Monolithic construction has become widespread today; not only large administrative premises and multi-storey buildings are built using this technology. residential buildings, but also individual buildings, for example, cottages. Scientific and technological progress responds to this trend in construction fashion - today monolithic buildings are erected quickly and efficiently using concrete pumps. However, such equipment is very expensive, which is why many individual developers are interested in whether it is possible to assemble a concrete pump with their own hands. If you show engineering ingenuity and manual dexterity, you can assemble a completely decent concrete pump, which will be quite enough for the construction of a cottage.

Classification of concrete pumps

Before you run to assemble a concrete pump with your own hands, you need to understand with your own brain what types of such pumps there are, what are their differences and advantages. All concrete pumps are divided into 2 groups according to the principle of operation:

piston concrete pump;
rotary concrete pump.

Rotary concrete pumps are too complex to manufacture and ultimately too expensive, so they are used only by professionals. Therefore, we will focus on the piston type. A piston fuel pump consists of 3 main elements:

cylinder;
drive;
piston.

Naturally, these elements have a much more complex structure and consist of many smaller elements.

Detailed structure of piston concrete pump

The concrete pump cylinder is a hollow part with 2 valves. These valves, opening alternately, allow liquid concrete to be taken from the tank and pumped into the concrete pipeline. And this, in turn, is possible due to the movement of the piston and the change of phases of the rarefied atmosphere and ultra-high pressure. To meet the needs of private housing construction, a simple model with one piston is quite sufficient. On large construction sites, where there is a need for high productivity, two-piston models are also used, but they are too expensive and difficult to manufacture - it is almost impossible to assemble a two-piston concrete pump with your own hands.

In general, in order to make a functional concrete pump yourself, you need to pay great attention to the design and creation of drawings. Sample drawings can be found online, and you can also use them. Or you can contribute your own know-how - it’s your choice.

How to make a piston concrete pump with your own hands?

Probably the most difficult thing when making a concrete pump is making the cylinder and piston. The fact is that they must have fairly large dimensions - the cylinder diameter is at least 40 cm, and the piston stroke is at least 50 cm. Therefore, the most reasonable solution would be to order the production of parts from a familiar turner. After all, for this you will need a lathe, and not every home has one.

In order for the piston to continuously move in the cylinder and pump concrete into the wire, a drive is needed. An electric motor is best suited for this. It is more productive, more reliable, and more affordable than any other options. A gearbox, which acts as a gearbox, and a rotation-to-translational impulse converter are connected to the electric motor.

All elements of the concrete pump must be firmly connected to each other to prevent possible way out failure during use is a real danger. In addition, it is necessary to check the quality of all connections every time, and also clean all working elements from concrete residues.

In general, before you start using your device, you need to conduct operational tests. You cannot test a concrete pump empty, this can kill it ahead of time! You can pour it in concrete mixture With high content water.

Monolithic construction is impossible without the use of special equipment - a concrete pump, through which the finished concrete mixture is moved to the pouring site. The use of such a unit significantly reduces the labor intensity of construction and the time required for its implementation.

This article presents step by step instructions, following which you can make a concrete pump with your own hands. We will also look at common industrial pump models, their operating principles, technical specifications and operating features.

Concrete pump - device, purpose, classification

The need to use a concrete pump is explained not only by the increased labor intensity of monolithic construction, but also by the fact that concreting technology requires simultaneous pouring of the structure even with large volumes of work.

Only a structure, during concreting of which partial hardening of the concrete layers was not allowed, can be considered monolithic. If a new portion was poured onto a partially hardened previous one, the final strength of the structure will significantly decrease due to microcracks in the structure of the material.

Also, you cannot do without a concrete pump when concreting structures with dense reinforcement, when it is necessary to supply concrete to a large height or length, when filling cavities and working in cramped conditions.

All concrete pumps on the market, depending on the principle of operation, can be divided into two types:

with mechanical drive;
with oil-hydraulic drive.

Until recently, mechanically driven units were the most common, but they have a significant drawback in the form of a short piston stroke, which causes uneven supply of solution. Also, mechanical equipment has less power than its analogue. Such pumps can pump concrete no more than 300 m horizontally and no higher than 40 meters vertically. Installations with an oil-hydraulic drive do not have such disadvantages. Their piston stroke is increased to 200-250 cm, whereas for mechanical units it does not exceed 40 cm.

The operating principle of both types of pumps is identical. They are equipped with two transport cylinders - concrete is pumped into the first cylinder from a receiving hopper, after which a reciprocating piston moves the mixture into a concrete pipeline, through which the solution is transported to its destination.

The pump always works in tandem with a concrete pipeline - a prefabricated pipeline (less often - a rubber hose), which is deployed directly at the construction site. It is also mandatory to have a conventional water pump for flushing the main components of the equipment and the concrete pipeline.

1.1 Varieties and popular models

Stationary units for supplying concrete, depending on the type of running base, are classified into 2 types:

wheeled;
tracked (used in conjunction with drilling machines)

Conventional wheel pumps are the most common class. Such equipment is also called a trailed concrete pump, since the concrete pump is mounted on a wheeled chassis and transported to the site as a trailer.

Among the trusted domestic manufacturers, we highlight the BN company; it is their concrete pump BN 40 that can be found on 80% of construction sites.

BN 40 is a small-sized oil-hydraulic concrete pump. Among the advantages of this unit, we highlight the presence of an electronic control system, which allows you to program the equipment for any operating mode, a built-in washing system, and a factory-equipped 80-meter concrete pipeline.

The BN 40 concrete pump is equipped with two Euro-4 diesel engines with a total power of 37 kW. Its design allows you to adjust the gap of the concrete distribution unit, which makes it possible to transport solutions from different sizes filler ( maximum size fractions - 40 mm).

Let's look at the technical characteristics of the BN-40:

productivity - 40 m 3 /hour;
nominal supply pressure - up to 75 Bar;
maximum feed height - 100 m, range - 400 m;
diameter of the pipe for connecting the concrete pipeline is 125 mm;
volume of the receiving hopper - 0.6 m 3 ;
The volume of the flushing system tank is 200 l.

The BN 40 concrete pump consumes 9 liters of diesel fuel per hour of operation, the volume of the fuel tank is 39 liters. Dimensions of the unit are 457 * 1.8 * 2.4 m, weight - 3120 kg. Spare parts for BN 40 concrete pumps are relatively inexpensive, and the equipment itself is characterized by increased reliability and wear resistance, which is the reason for the wide popularity of this model.

Among foreign manufacturers of equipment for supplying concrete, we note the company Schwing-Statter (Germany). The company produces both stationary and automotive pumps and concrete mixers. The line of stationary units includes over 10 models, the most popular of which are:

Concrete pump Schwing SP 305 - supply volume 23 m 3 /hour, pressure - 43 Bar, height - 60 m, range - 245 m.
Swing SP500 - feed volume 35 m 3 /hour, pressure - 75 Bar, height - 100 m, range - 360 m.
Swing SP 2800 - feed volume 101 m 3 /hour, pressure - 110 Bar, height - 170 m, range - 500 m.

There is also a class of low-capacity equipment, which is commonly referred to as a mini-concrete pump. Such units are intended for use in individual low-rise construction; they are capable of pumping up to 5 cubic meters of concrete or foam concrete per hour with a supply pressure of up to 10 bar. This niche is dominated by Chinese manufacturers - Hongda and Zoomlion.

2 Features of making a concrete pump with your own hands

To make a concrete pump at home, you will need three main components - an electric drive, a piston and a cylinder. You can buy a motor at a disassembly site or flea market; you can order the turning of the piston and cylinder from a familiar turner or do it yourself.

A homemade concrete pump must be assembled on the basis of a cylinder with a diameter of 40 cm; the optimal piston stroke is considered to be 50 cm. Keep in mind that a decrease in the working stroke directly affects the acceleration of wear of the piston group. The design of a homemade pump does not require the presence of transport cylinders - pumping is carried out directly from the receiving tank.

To assemble the pump you will need the following tools:

wrenches;
angle grinder (grinder);
lathe;
welding machine;
screwdriver

It is best to use a three-phase asynchronous motor as a motor; you will also need a reduction gearbox and a transmission mechanism, through which the rotational movement of the motor will be converted into the reciprocating movement of the piston group.

Leave your comment

Construction work in the private sector is carried out constantly and at a fairly rapid pace. Of course, haste has not yet brought full benefit to anyone, but given the rising cost of materials and work, you want to speed up the process, and this can only be achieved with auxiliary equipment. If we are talking about pouring monolithic foundations, formwork or floors, then practically no alternative is to use devices for supplying the finished mixture to work area. To save even more, you can not resort to renting, but make a concrete pump yourself, based on existing manuals. Let’s try to figure out further what this technique is, what it consists of, and how to make it work.

Pouring foundations or floors involves creating a homogeneous mass. Doing this manually with large volumes and areas is almost impossible. This approach leads to the formation of focal structures: part has already begun to harden, and more is gradually added to it fresh concrete. Obviously, this structural element will not have uniform characteristics; its shrinkage and shrinkage at different points will follow its own scenario.

You can speed up the pouring process, and therefore bring the structure as close as possible to the required one, by using mixers in combination with concrete pumps. The former ensure continuous preparation of the mixture, and the latter ensure its supply to the working area. The main difference between such superchargers and conventional water pumps is the structure of the moving medium. Concrete is a more viscous, thick (paste-like) material, which forces the use of slightly different principles and technologies for its transportation. Products existing on the market are divided into two large groups: rotary and piston.

1. Rotary concrete pumps.

These are transport mechanisms that use flexible suction and pressure hoses (positions 1, 5 and 9 in the illustration).

Like in any car of this type? there is a main chamber where the sleeves and a rotating eccentric rotor 4 are located. It has rubber-coated rollers 3, which, during rotation, compress sections of the suction and intermediate lines, pushing the mixture into the supply line. Such machines have a volumetric capacity of up to 70 m3/hour, with a horizontal and vertical head of 300 and 70 m, respectively. Due to the high complexity of the design and manufacturing technology of individual components, it is unlikely to be possible to assemble a concrete pump of this type on your own and focus attention on it doesn't make sense.

2. Piston concrete pumps.

These are more productive (up to 200 m3/hour) and widespread machines. Unlike the previous type, here driving force is not a rotor with rollers, but a piston that pushes a certain dose of concrete into the supply line. Industrial designs use a scheme with two parallel pistons, which are alternately connected to the concrete pipeline through a C- or S-shaped gate.

During operation of the concrete pump, concrete from the hopper is supplied to the chamber with the gate and sucked into one of the cylinders that are open at that moment. After filling, the gate is connected to it and the piston pushes the concrete into the supply pipeline. Then, in the adjacent block, the working unit moves back and material is collected.

Periodic switching of the feed cylinders allows you to save on their size (primarily length), ensuring continuous supply in accordance with the instructions.

Assembling such a concrete pump with your own hands is not as complicated a procedure as it might seem at first glance. Moreover, if we take into account the relatively small volumes of work in the private sector, the scheme can be significantly simplified by using only one pressure cylinder. This will reduce the number of upcoming actions and their overall cost.

Where to start? Step by step instructions

Any technically complex undertaking can be implemented in practice, subject to a competent assessment of the situation and correct calculations. It is necessary to analyze existing technologies, select an acceptable scheme for the manufacture and assembly of individual components and assemblies for working with concrete, find suitable materials and finished parts. You also need to develop drawings according to which the piston, cylinder, and body will be created. It would be a good idea to prepare operating instructions for the concrete pump.

Preparation of project documentation is also carried out independently, especially if you have specialized education and understanding of the basic principles of development. If this does not work out, then you need to seek help or advice from professionals or search for information on the Internet: on specialized forums you can easily find ready-made drawings and manuals for assembling and operating units for working with concrete.

How to make the main elements?

The accuracy of the functioning of the concrete pump depends on how optimally the parameters of its main components were selected. The diameter of the master cylinder is selected based on the range of 42–400 mm. The piston stroke will be recommended to be within the range of 500–900 mm to ensure a sufficient volume of concrete unloading.

It is recommended to make check valves used in the design from alloyed, preferably stainless steel, which will significantly extend their service life in direct contact with concrete. Parts that have the shape of a shaft are turned from blanks to lathe. The required size accuracy is adjusted by grinding. It should be noted that when docking, the deviation should be within ±0.1 mm.

The main components of the concrete pump are assembled using screwdrivers and wrenches. The finished pump is connected to a drive (hydraulic, mechanical). In the first case, a hydraulic system is used, which guarantees greater travel and durability. The second option uses an intermediate gearbox, as well as a crank pair. In this case, it is impossible to ensure a sufficiently long stroke, which means that the frequency of movements increases, which inevitably affects the service life.

The average cost of manufacturing such a concrete pump is in the range of 50,000 - 60,000 rubles, but depending on the materials and components, as well as the economic situation affecting pricing, this figure may differ (usually upward).

Correct use of equipment

The first stage, the starting point in the process of working with a concrete pump, is its start-up and running-in - sea trials. It is strictly forbidden to perform a test run in idle mode on a concrete pump that is not filled with material. Machine oil and concrete are used as a working mixture, which is diluted with a sufficient amount of water.

Each operational cycle must be completed with scheduled disassembly and cleaning in accordance with the instructions. This should be done because it will be extremely difficult to chip away at hardened concrete, and constant contact with the working surfaces can lead to their premature wear.

A homemade concrete pump is useful in monolithic construction a unit for working with concrete, which allows you to speed up the process of pouring the mixture and save on the services of private companies. But its production must be thoughtful so that the money and time spent on development and assembly can be guaranteed to pay off.

Every year construction industry is developing faster than we think, although it is still far from the large-scale construction sites that existed in the 60-80s of the last century. For pouring foundations, as well as for technological processes construction, the optimal solution would be a do-it-yourself concrete pump, which can be created from existing materials and technologies. You can build a simple, and at the same time effective, homemade concrete pump for any production site - industrial facilities or private housing construction.

Categories of industrial equipment

According to generally accepted specifications, it is customary to subdivide several categories of concrete pumping equipment, in particular:

Stationary option. Suitable for large industrial construction sites, while the equipment can operate under high loads and volumes, regardless of the complexity of the construction process.
Mobile option. This type is preferable for those who are involved in several construction projects in a row. In this case, a small-sized concrete pump can be easily transported on vehicle from one construction site to another.

In addition to the main classes of concrete pumping equipment, there are differences in the performance of the equipment, as well as in the method of power supply and connection. In some cases, there is a difference in supply by category and type of concrete loaded. In general, when creating a concrete pump with our own hands, we will see what technical properties the equipment has:

Vacuum type. The material is supplied by squeezing the finished processed material out of the tray under the influence of a vacuum pump.
Piston type. The supply of building material is carried out through the interaction of elements of the piston group.

The general classification of equipment is capable of working both in a horizontal position and with vertical installation of special equipment.

Piston installation

In order to create autonomous equipment on your own, a piston version is suitable, and after watching the video of a do-it-yourself concrete pump, you will be convinced that homemade installation will work no worse than production analogues. For assembly you will need:

Drive mechanism.
Cylinder.
Piston element.

These components will be the basis for assembly autonomous equipment. In addition, there are a number of small spare parts that are used during the assembly process. The cylinder has a special vessel shape, where there are 2 valves for the reverse process. It is the cylinder that ensures the pumping of concrete mixture from a special receiving point to the concrete-containing part. An efficient work process is ensured by the coordinated operation of two main mechanisms - the cylinder and the piston element.

At the very beginning of work, the piston is started, which creates a conditional discharge inside the cylinder, and thereby the mixture is distilled into the receiver. Next, the piston mechanism moves to the end of the structure and then returns to its original state. The presence of several factors leads to the creation of pressure, due to which the concrete solution moves.

If we consider the industrial version of the equipment, the concrete mixture is supplied by a concrete pump using built-in two piston elements inside the system. Industrial type concrete pumping equipment is ideal only for large production purposes, but for minor works It is enough to build a homemade apparatus with different performance.

What tools and materials are needed for the job?

To build a high-quality concrete pump on your own, you will need a number of tools and devices that are necessary to create the installation:

Steel sheet, preferably at least 5mm thick.
A pipe of the appropriate diameter for the cylinder (metal).
Round shaped metal sheets to create the piston and valve mechanism.
Turning equipment for processing workpieces and giving them the appropriate shape.
Electric drive, motor of appropriate power.
Cordless or electric drill.
A set of locksmith wrenches of various configurations and bolted connections.
For a concrete pipeline - a plastic or analogue plastic pipe.
Gear complex with reducing transmission characteristics of mechanisms.
Solid or welded frame for installation.

What you need to know to make a piston group and cylinder

To manufacture a cylinder mechanism, it is necessary to use a pipe or blank of at least 400 mm. The length of the piston stroke should be about 50cm. By using other underrated or overestimated parameters of the cylinder and piston element, you may encounter the fact that the hose for the concrete pump will not be able to withstand the load and this will lead to premature wear of the equipment. Extreme precision should be the main factor in the manufacture of the piston group and cylinder of concrete pumping equipment.

Manufacturing workflow

The drawings should be the basis for creating the equipment. To be able to use the equipment for its intended purpose, contact specialists who will help you develop technical documentation. In addition, not the last option for searching for drawings would be to view ready-made drawing documents on the Internet. When developing parts, pay attention to the length of the concrete pump hose, which is an integral part of the technological equipment and the quality of its work.

Choosing an automatic drive

For a device that will perform its direct functions, you will need to install a drive. The right decision will be the choice of an electromechanical drive as opposed to a hydraulic option. Electromechanics can recoup the cost of creating a concrete pump with your own hands several times. To manufacture the final version of the electromechanical drive, you will need a gearbox with reduction characteristics, an asynchronous type electric drive, and a complex transmission mechanism, with the help of which various rotational actions are produced - modified after starting into translational rotation.

In order for the translational movement mechanism to be adapted to the piston, it is necessary to connect a king pin to the device. In this case, you will need a ready-made welded frame for the frame structure. It is necessary to take into account that the finished steel frame must be very high quality execution.

When manufacturing cylinder mechanisms - valves, pay close attention to the task of manufacturing only high-quality parts. In this case, you will need a high grade of alloy steel, which is capable of interacting with the aggressive characteristics of the finished concrete mixture for transfer to the concrete pipeline.

Summary of equipment assembly

In order to put the concrete pump into operation, it is necessary to carry out preparatory work. For starting work, take a specially prepared mixture, which includes cement mixture with the addition of a small amount of machine oil. We pour the prepared mixture into the pump and observe what characteristics the device shows you when interacting with this material. Remember that only after you have carried out preliminary tests, you can use the equipment for work. In any case, increased safety precautions must be observed during operation. homemade equipment for supplying concrete to the construction site.

How to make a concrete pump with your own hands? Homemade concrete pump

working principle and how to do it

Concreting is the most common type of work in construction; it is used in most areas. To make working with heavy mortar easier, special devices for preparing and transporting cement have become widespread. The simplest but most expensive way to move mortar is with a concrete pump, but the cost of installation puts off small firms. It is possible to create a concrete pump with your own hands, and the costs will be 30-40% less.

Operating principle of a concrete pump

A concrete pump is a device with the sole task of preparing and delivering concrete from the mixing point to the target area. The installation is based on pipelines or concrete pipes that transfer the solution to any location. The greatest need arises in monolithic construction and when creating reinforced concrete structures.

Mobile concrete pump with high capacity on a crawler chassis

To understand the method of constructing the installation, you should know how a concrete pump works. The operating principle of a concrete pump is based on the properties of the liquid - it displaces and fills the changing volume of the system. If the volume is completely filled with the mixture, the solution is discharged into the concrete pipeline and then to the target area.

The design and principle of operation of a concrete pump is divided into several groups:

piston Perform a constant feed at various distances. Modern devices are capable of displacing liquid to a height of 6-65 m. The volume of the supplied mixture reaches 180 m3/h. It is not durable due to the risk of small elements of cement getting in. Has a jerky delivery principle.
hose (screw). Provide continuous transportation. The gerotor pump for concrete provides a large volume of transported material. The installation is characterized by silent operation when pumping compounds of any consistency. If a blockage occurs, it is broken through by reversing the engine. A gerotor pump for pumping concrete has one significant drawback - the hose has a short service life, but the structure can easily be repaired independently;
with hydraulics. If there are hydraulic units for working with concrete, the devices become more durable and smoothly transfer the solution (without jerking or changing speed). Hydraulics help pump liquid to heights and long distances. The hydraulic drive is made as simple as possible; the device results in low energy consumption. Hydraulic pumps help pump mortar containing lightweight aggregates and are easy to operate and maintain.

Construction of a piston concrete pump

Drawings of concrete pumps for DIY production differ significantly depending on the type. All models differ in design, but have similar disadvantages to a greater or lesser extent:

the use of rolling stock is mandatory;
limited transportation range;
demands on the composition of the solution.

The price of a homemade concrete pump directly depends on the required power and pipe diameter. For larger pipes the pressure decreases. Recently, concrete pumps (the ability to supply concrete to a target area at various distances) and concrete pumps (smaller dimensions and mobility) have become very popular.

Unit types

Conventionally, devices are divided into 2 categories: with a mechanical unit or a hydraulic element. Rotary and piston concrete pumps have their own operational advantages and disadvantages.

Operation of the piston system

Piston systems operate on the same principle in all applications. At the stage of downward movement, a certain volume of liquid and concrete receiver is sucked in; in the second cycle of work, the solution is pushed out into the transfer sleeve. The mixture is supplied to the working area through the pipeline.

Mechanical driven piston concrete pump

The operation requires the use of a slide gate, which opens the concrete receiver during the suction stage and closes it during the ejection process. The gate regulates the direction of fluid flow. During testing, it is necessary to add machine oil to the working mixture.

The design includes a mechanical drive or a hydraulic system. Modern concrete pumps work with hydraulics, since the system is highly efficient, it leads to the formation of greater pressure and increased pump power. Compared to a connecting rod assembly, the hydraulic system provides a greater range of piston stroke and smoother movement. A potential problem is loose contact between the piston and the chamber. Microscopic particles of cement penetrate between the piston and cylinder, accelerating wear many times over.

Devices with 1 cylinder are practically not used, as they lead to a pronounced pulsation of the solution supply. Mostly, two cylinders are built into the system; they work alternately - so the concrete is supplied smoothly and continuously. Also, a mechanism with two cylinders wears out less.

Rotor system operation

The use of rotary concrete pumps is much more common, since pistonless systems are more reliable. It is based on a rotor with fixed rollers (covered with rubber). As the rotor rotates, the rollers move, transferring the mixture from the concrete receiver to the working hose. An important advantage is the reverse function to remove air pockets and blockages.

Design of a rotary concrete pump

Equipment operation and repair are easier. The weak point of the structure is wear of the hose or seals - both faults can be easily eliminated with your own hands. Other disadvantages include low power (compared to the piston type) and poor tolerance of coarse filler.

There are also screw pumps for pumping concrete, but they are inferior in durability and performance. Their operating principle is elementary: a screw is placed in a through chamber, which displaces the substance during rotation.

Rotary mechanisms are presented in many modifications, the main difference being the method of placement: stationary and automotive.

Unit mounting options

Stationary pumps

Before making a concrete pump with your own hands, you should decide on the type of base it will be based on. The stationary option is a separate station for pumping the substance. Dimensions vary widely; there are concrete pumps for small-scale construction and the construction of industrial facilities. For movement, a chassis is often installed.

A mobile structure without a chassis predominantly has high power; it is recommended to use a concrete pump to supply large-scale construction with substances, more often high-rise buildings. If there is a chassis, transportation over long distances is not provided; they are intended for movement within one area.

Stationary mixer and concrete pipeline

Today, a new type has been developed - a towed device; it is distinguished by a powerful chassis that allows the installation to be moved over long distances by a tractor. For the construction of private housing or household structures, a mini concrete pump with a piston mechanism has been created, less commonly found with a pneumatic drive. It helps when working with small orders or in cramped conditions.

The pneumatic installation is designed to work with homogeneous cellular solutions; it is characterized by low power and the need to connect a compressor, but a stable supply of solution.

Pumps on a car base

The automotive type of pump is the most common in all areas of construction. Like other gardening equipment on wheels, the concrete pump can be easily moved independently, and also has characteristic differences:

a stationary station with high power is applicable exclusively for large-scale construction; it is expensive to maintain and unmaneuverable. Automotive option able to drive to most objects;
for stationary type units, special power supply is required; in construction conditions it can be difficult to create suitable conditions. In a concrete pump truck, power comes from the machine installation;
a small pump has low performance, and the cost of installation is not affordable for all contractors. In terms of savings, renting a car unit is cheaper, and in addition it helps to complete the job many times faster;

Pumps on a car base

Modern auto complexes have a built-in retractable boom, which simplifies the delivery of the solution to target areas with difficult access or located at height. If a boom is not applicable, a line pump is used to help pump the solution up to 1 km and 120 m in height;
Thanks to a professional operator in the equipment cabin, the customer is relieved of all risks of device breakdown.

Concrete pump – buy or make it yourself?

There are many offers on the used special equipment market, but first you should think about the feasibility of the purchase, because there is an option to make a concrete pump yourself. Basic skills will be required to create the installation. Homemade installations are less powerful and have a simpler design, but when properly manufactured they work properly and smoothly.

Initially, it is important to decide on the operating principle of the concrete pump: piston or hydraulics. The piston type is the simplest, but leads to rapid wear of the unit elements due to constant friction. Hydraulics are much better in performance, but are more difficult to manufacture. It is possible to make an automatic concrete pump, but they are less powerful.

Before starting to make a concrete pump with your own hands, important attention is paid to the gate - this is a kind of valve that ensures high-quality adhesion between the concrete pipe and the pump. The operation of the structure depends on the correct choice of gate.

How to make a concrete pump - production technology

During the work, auxiliary tools will be required; thermal insulation is a desirable measure. A do-it-yourself gerotor pump is made according to a single scheme. Key points for assembling a concrete pump:

Assessment of the feasibility of production. For large-scale construction, it makes sense to purchase your own installation. For small and medium volumes of work, it is profitable to rent a concrete pump. A homemade concrete pump is a relatively complex and expensive process.
Creating a drawing. The concrete pump diagram is simple; its design will require minimal design skills or use existing diagrams. Self-production- This is a more difficult method, but allows you to create a design for specific needs. The use of ready-made diagrams is convenient due to the reduction in time costs and the ability to study reviews about the shortcomings of the drawing or find ways to improve the design in them.
Selection of cylinder and piston. Key element systems should be selected with power reserves. The maximum cylinder diameter is 400 mm, it is better to choose smaller models. The piston stroke estimate is from 50 cm. If the parameters do not match, the number of working cycles increases, and as a result, rapid wear.
Adjustment of piston and cylinders. In order for the pump to serve for a long time, it is necessary to perform high-precision fitting and eliminate roughness.
Selection of node type. An electromechanical pump will help reduce the complexity and cost of manufacturing the device. The hydraulic option can be prepared manually, but this will increase costs and complicate the process.
Gearbox installation. The mechanism must include a gear ratio to reduce and convert rotational movements into translational ones.
Installation of the king pin. The element is connected to the mechanism. A metal corner is used to prepare the welded frame. Enter into the system check valves Made of alloy steel, it is wear-resistant.

After preparing the parts and assembling the pump, all that remains is to check the functionality of the installation. It is prohibited to start the device without concrete or a specialized starting mixture (manually made from cement with water and the addition of automobile oil).

Concrete pump drawing

Monolithic high-rise buildings are almost always built using a concrete pump. The installations help deliver concrete to any floor with minimal time and physical costs.

With regard to private construction, the situation is somewhat more complicated, since access to the site for special equipment is limited, and manual preparation of the solution is an extremely lengthy procedure. Automotive units are quite large; in working condition, the equipment takes up up to 12 m in width; using a boom requires even more space, up to 70 m. Mini concrete pumps will help eliminate the problem, simplifying the task and speeding up construction.

You can order concrete with a concrete pump for small construction in combination with a KamAZ truck, on which the main line is fixed: 2 pipes with connecting clamps. An improvised concrete pump with a KamAZ truck is the largest version of a concrete pump.

If no truck arrives at the site, assembly must be done manually, but the participation of 2 and more people. Potential problems manual installation:

line rupture. There is a lot of pressure in the system, the clamps are not always able to withstand the pressure. Pulling out the fastener creates a hole. You will have to stop the system, clean the pipeline and make a more durable fastening;
relocation of the highway. When changing jobs, it is necessary to move the pipe, but this cannot be done together with the solution. The lines will have to be disassembled, cleaned and reinstalled.

The long time required to set up the operation of the equipment is still significantly less than manually mixing the mixture.

Application of concrete pumps in construction

Advantages of automatic concrete pumps

Automatic production plants have numerous advantages:

There is a built-in electronic control unit that monitors the correctness and continuity of operation. The operator selects the operating mode, and the unit independently regulates the operation of the installation;
independent flushing system for pipes and pump. Reduces time spent on maintenance and clearing congestion;
lighting the surrounding area for working with the concrete pump after dark;
sound alerts about major events;
adjustment of gaps in the concrete distribution unit;
All pumping units supplied with a flushing system, special software and a concrete pipeline up to 80 m;

technology, dimensions, sleeve (hose) length

Every year the construction industry is developing faster than we think, although it is still far from the large-scale construction sites that existed in the 60-80s of the last century. For pouring foundations, as well as for construction processes, the optimal solution would be a do-it-yourself concrete pump, which can be created from existing materials and technologies. You can build a simple, and at the same time effective, homemade concrete pump for any production site - industrial facilities or private housing construction.

Categories of industrial equipment

According to generally accepted specifications, it is customary to subdivide several categories of concrete pumping equipment, in particular:

Stationary option. Suitable for large industrial construction sites, while the equipment can operate under high loads and volumes, regardless of the complexity of the construction process.
Mobile option. This type is preferable for those who are involved in several construction projects in a row. In this case, a small concrete pump can be easily transported by vehicle from one construction site to another.

Vacuum type. The material is supplied by squeezing the finished processed material out of the tray under the influence of a vacuum pump.
Piston type. The supply of building material is carried out through the interaction of elements of the piston group.

The general classification of equipment is capable of working both in a horizontal position and with vertical installation of special equipment.

Piston installation

In order to create autonomous equipment on your own, a piston version is suitable, and by watching the video of a do-it-yourself concrete pump, you will be convinced that a home-made installation will work no worse than its production counterparts. For assembly you will need:

Drive mechanism.
Cylinder.
Piston element.

These components will be the basis for assembling autonomous equipment. In addition, there are a number of small spare parts that are used during the assembly process. The cylinder has a special vessel shape, where there are 2 valves for the reverse process. It is the cylinder that ensures the pumping of concrete mixture from a special receiving point to the concrete-containing part. An efficient work process is ensured by the coordinated operation of two main mechanisms - the cylinder and the piston element.

If we consider the industrial version of the equipment, the concrete mixture is supplied by a concrete pump using built-in two piston elements inside the system. The industrial type of concrete pumping equipment is ideal only for large production purposes, but for small-scale work it is enough to build a home-made apparatus with different capacities.

What tools and materials are needed for the job?

To build a high-quality concrete pump on your own, you will need a number of tools and devices that are necessary to create the installation:

Steel sheet, preferably at least 5mm thick.
A pipe of the appropriate diameter for the cylinder (metal).
Round shaped metal sheets to create the piston and valve mechanism.
Turning equipment for processing workpieces and giving them the appropriate shape.
Electric drive, motor of appropriate power.
Cordless or electric drill.
A set of locksmith wrenches of various configurations and bolted connections.
For a concrete pipeline - a plastic or analogue plastic pipe.
Gear complex with reducing transmission characteristics of mechanisms.
Solid or welded frame for installation.

Manufacturing workflow

Choosing an automatic drive

For a device that will perform its direct functions, you will need to install a drive. The right decision would be to choose an electromechanical drive as opposed to a hydraulic option. Electromechanics can recoup the cost of creating a concrete pump with your own hands several times. To manufacture the final version of the electromechanical drive, you will need a gearbox with reduction characteristics, an asynchronous type electric drive, and a complex transmission mechanism, with the help of which various rotational actions are produced - modified after starting into translational rotation.

In order for the translational movement mechanism to be adapted to the piston, it is necessary to connect a kingpin to the device. In this case, you will need a ready-made welded frame for the frame structure. It is necessary to take into account that the finished steel frame must be of very high quality.

Summary of equipment assembly

In order to put the concrete pump into operation, it is necessary to carry out preparatory work. For starting work, take a specially prepared mixture, which includes a cement mixture with the addition of a small amount of machine oil. We pour the finished mixture into the pump and observe what characteristics the device shows you when interacting with this material. Remember that only after you have carried out preliminary tests, you can use the equipment for work. In any case, it is necessary to observe increased safety measures when operating homemade equipment for supplying concrete to a construction site.

Monolithic construction has become widespread today; this technology is used to build not only large administrative premises and multi-storey residential buildings, but also individual buildings, for example, cottages. Scientific and technological progress responds to this trend in construction fashion - today monolithic buildings are erected quickly and efficiently using concrete pumps. However, such equipment is very expensive, which is why many individual developers are interested in whether it is possible to assemble a concrete pump with their own hands. If you show engineering ingenuity and manual dexterity, you can assemble a completely decent concrete pump, which will be quite enough for the construction of a cottage.

Classification of concrete pumps

piston concrete pump;
rotary concrete pump.

cylinder;
drive;
piston.

Naturally, these elements have a much more complex structure and consist of many smaller elements.

Detailed structure of piston concrete pump

How to make a piston concrete pump with your own hands?

All elements of the concrete pump must be firmly connected to each other to prevent possible failure during use - this is a real danger. In addition, it is necessary to check the quality of all connections every time, and also clean all working elements from concrete residues.

In general, before you start using your device, you need to conduct operational tests. You cannot test a concrete pump empty, this can kill it ahead of time! You can pour a concrete mixture with a high water content into it.

types, application and self-production

IN modern construction The timing of the work plays a very important role. At the same time this feature is associated not only with obligations to the customer, but also with some features of the materials. That is why such a device as a concrete pump is very popular among craftsmen.

Varieties

To begin with, it is necessary to say that there is simply a huge number various types device data. They have different dimensions, working space volumes and concrete supply systems. However, even the most ordinary concrete pumping unit can supply ready solution at a distance and a certain height.

Structures on a car chassis can be classified as special equipment

Types by mobility

The most common are mobile installations of this type. They are installed on a vehicle chassis and can follow immediately behind the vehicle delivering the solution. Therefore, they are ordered along with concrete and are paid only for hourly work, although the price for such services is quite high.

The unit mounted on a trailer solves the problem of mobility and size

It is important to note that this technique is also divided into separate classes, which are determined by the length of the arrow. This must be taken into account when ordering this vehicle in order to provide convenient access.
There is also a stationary concrete pump. It is installed directly on site and can be used throughout the entire duration of the work. It is worth noting that such equipment is usually used if the solution is prepared independently or the supply flow is established.

Advice! You should choose an installation of this type based on economy and ease of installation. Otherwise, this will lead to additional costs that will not be justified even by the high installation speed.

Types of solution supply

These technical characteristics of the concrete pump are not important to the customer or tenant. Properly configured and working equipment copes well with the task, regardless of the design of its mechanism.

However, if you plan to purchase such a unit, then you should find out in advance about some types of such structures.

Vacuum systems assume the presence of a receiver

Vacuum units use back pressure to extract the solution. At the same time, it is supplied to a height also due to the potential difference. This installation separates the concrete itself from the concrete pump, which is very important for maintenance and repair, since it can be disassembled into units.
Piston units are considered one of the simplest and most reliable. Their design resembles a syringe or a kind of plunger. In this case, the operating principle of the concrete pump of this type depends on the type of its feed mechanism.

Operating principle piston pump with two hydraulic cylinders as blowers

Piston installations are gate and curtain. It is these elements that are used as a separator between the main device and the supply system. Therefore, significant changes in performance can be observed.

Advice! The above systems are described very conditionally, since professional craftsmen recommend that when choosing a specific unit, you should focus on its performance indicators and the height of mixture delivery. The rest remains technical data that is needed only for repairs.

Operating principle of pistons at different pressure potentials

Mechanism of action

Typically, the operation of a concrete pump is associated with a number of difficulties, which are due to the fact that it is not always possible to find access to the electrical network at the construction site. Therefore, most often these units run on gasoline. This ensures their autonomy, which is very convenient for initial stage construction, when only concrete formwork.

However, it must be said that there are designs that use electrical energy. This concrete pump device is much more economical and has smaller dimensions.

Advice! Purchasing such systems is only beneficial for companies or large construction teams. To perform one-time work, it is much easier to rent such equipment.

Operation scheme hydraulic system

Self-production

Quite often on a construction site you can find a homemade concrete pump that does its job well and is quite easy to operate. However, it is worth saying that creating a product yourself can be very financially expensive and technically difficult. Therefore, you need to start this task after weighing all the positive and negative aspects.

To create pressure, you can use a simple compressor from the refrigerator

Design selection

When creating a concrete pump with your own hands, you need to choose those systems that will not cause serious difficulties and high costs during production. Therefore, experts advise choosing piston products. Their operating principle is to create pressure in a cylinder with two valves, allowing the mixture to enter the working space, which, during the reverse stroke, will be compressed, pushing the composition out.

Piston pump drawing

It is worth noting that for such work it is best to use ready-made drawings or create them yourself if you have the appropriate skills and education. In this case, the design instructions advise choosing the sketch that is based on the use of ready-made units. This will help save money and make the whole process easier.

Advice! The finished drawing should be shown to a specialist who can detect inaccuracies or make additions. Otherwise, there is a possibility of producing a unit that will not function.

Materials

Very often a concrete mixer is combined with a concrete pump, allowing the user to immediately simplify the feeding process.

However, such designs require a solid installation, preferably with vertical loading.

For power plant It is best to use an electromechanical drive. This is due to the fact that all remaining units are very expensive and have difficult operation.
If you cannot find the piston system in finished form, then you will have to create it yourself using alloy steel, which is processed on a lathe. In this case, it is advisable to make detailed drawing all elements so that the turner can make an accurate fit.

Advice! The entire manufacturing process depends only on the chosen design and the nodes found. Therefore, it makes no sense to describe it in detail.

Valve distribution patterns using different design configurations

By watching the video in this article, you can study in more detail the design and operating principle of these units. At the same time, based on the article proposed above, it is worth concluding that there is a mass various designs these devices, differing in different parameters.

You can also understand that it is quite difficult to make a concrete pump yourself. Sometimes it is much easier to purchase a finished product or rent it.
