What are the advantages of concrete pumps and what are the types of concrete pumps

Concrete pump, also known as concrete pump, is composed of a pump body and a delivery pipe. It is a kind of machinery that uses pressure to continuously transport concrete along pipelines, which is mainly used in housing construction, bridge and tunnel construction. It is mainly divided into gate valve concrete pump and S valve concrete pump.

The other is to install the pump body on the chassis of the car, and then equip the retractable or flexib distribution rod to form a pump truck.

Types: According to the structure and use, it is divided into trailer concrete pumps, truck-mounted pumps and pump trucks, and according to the power type, it is divided into electric concrete pumps and diesel-powered concrete pumps. Performance characteristics of concrete pump 1, the use of triple pump open system, hydraulic circuit does not interfere with each other, system operation.

2. It has the function of reverse pump, which is conducive to timely elimination of pipe blockage faults, and can stop for a short time to wait for materials. 3. The advanced S-pipe distribution valve is adopted, which can automatically compensate for the wear gap and has good sealing performance. 4. Wear-resistant alloy glasses plate and floating cutting ring are adopted, which has a long service life.

5. The long-stroke cylinder prolongs the service life of the cylinder and the piston. 6. The hopper with optimized design is easy to clean and has better suction performance. 7. Automatic centralized lubrication system to ensure that the machine is effectively lubricated during operation.

8. It has the function of remote control, which is safer and more convenient to operate. 9. All parts and components adopt national standards, and the interchangeability is good.

Abstract:Concrete pump, also known as concrete pump, is a machine that uses pressure to continuously transport concrete along the pipeline. There are many types of concrete pumps, which can be divided into truck-type concrete pumps and trailer-type concrete pumps in terms of mobility.

In terms of power form, it can be divided into electric type and internal combustion engine type. What are the different types of concrete pumps? Let's take a look at the following, first, what are the types of concrete pumps.

There are many types of concrete pumps, and the different classification methods will lead to the differences in the types of concrete pumps.

According to the structural form, concrete pumps are divided into piston type, extrusion type, and hydraulic diaphragm type. According to the structure and use, it can be divided into trailer concrete pump and truck-mounted concrete pump. According to the type of power, it can be divided into electric concrete pump and diesel-powered Soulu concrete pump.

In terms of pumping form, the inclined gate valve and the inclined gate valve are commonly used in China"s"The advantage of the former is that the diameter of the aggregate in the concrete is wider (40mm), and the price is lower, and the disadvantage is that the gate valve needs to be lubricated uninterrupted, and the pumping height is about 100m; The latter has no lubrication system, strict aggregate requirements (no more than 33mm), pumping height can reach more than 150m, and the selling price is generally higher.

Concrete transport pump, also known as concrete pump, is composed of pump body and conveying pipe, using pressure to continuously transport concrete along the pipeline, mainly used in housing construction, bridges, tunnel construction, etc.

Second, what are the types of concrete pumps?

1. Sky pump. The sky pump is also called a boom pump, and there are two kinds of pumps: those with and without stirring function. The day pump is also often said to be a concrete pump truck, it has its own independent support, so it can transport concrete without laying pipelines, usually the operation flexibility of the concrete pump truck is quite good, and the speed is also very fast, but compared with other concrete pumps, its maintenance and use costs are relatively high, but because it is limited by the height of the operation, it has a lot of requirements for the site.

2. Vehicle-mounted pump.

Compared with the truck-mounted pump and the sky pump, it does not have an independent bracket, and its advantage is that it occupies a relatively small space, so the relative cost is relatively low, and because there is no bracket, the labor intensity of workers is relatively large. However, compared with the sky pump, the advantage of the vehicle-mounted pump is that the operating cost is low, so if the high-pressure pipe is used, the conveying height will be relatively high.

3. Ground pump. The ground pump, also called the tow pump, cannot walk independently because there is no car chassis, but there are tires that can be towed to the site of the slag group with a tractor. Compared with the sky pump and the truck-mounted pump, the operating cost of the ground pump is relatively low, but its disadvantage is that the conveying speed is slow and the conveying height is not as good as the truck-mounted pump.

4. Stirring pump.

The mixing pump also comprises a mixing trailer pump and a mixing truck pump, the mixing trailer pump cannot walk independently, the mixing truck pump can walk independently, and the mixing pump has increased the mixing function compared with other concrete transfer pumps, and can carry out on-site mixing.

Piston concrete pump is known for sale.

There are hydraulic transmission type and mechanical transmission type. The hydraulic transmission concrete pump is composed of hopper, hydraulic cylinder and piston, concrete cylinder, distribution valve, Y-pipe, flushing equipment, hydraulic system and power system, etc. The hydraulic system pushes the piston to reciprocate by pressure.

When the piston moves back, it sucks the material, and when it pushes forward, the concrete in the concrete cylinder is pressed into the conveyor pipe through the Y-shaped pipe. After pumping concrete, the pump body and delivery pipe are cleaned with high-pressure water finger or compressed air. The displacement of the piston concrete pump depends on the number and diameter of the concrete cylinder, the reciprocating speed of the piston and the volumetric efficiency of the concrete cylinder suction.

Concrete pump machine is classified according to displacement, when choosing displacement, it is necessary to consider whether the concrete pump is commercial concrete or on-site mixing, if the concrete pump is on-site mixing, then it is necessary to consider factors such as the amount of square and pumping distance per unit time; Concrete pump machine can also be classified according to the power, how big the concrete pump machine to choose the motor concrete pump, first consider the capacity of the transformer, and then consider the distance from the concrete pump and the size of the wire diameter, the purpose is to prevent the increase in current caused by excessive voltage drop and cause tripping and shutdown.

The hydraulic system of the large concrete pump greatly improves the overall reliability of the machine and ensures that the machine can work without failings under harsh conditions. It mainly produces various types of motors with pumping efficiency of 15-120 h and concrete pressure of 5-20MPa for diesel engines.

Large concrete pump is suitable for high-rise buildings, high-speed road dust, overpasses, bridges, mines and other large-scale concrete projects mixed delay concrete conveying work.

Small concrete pump trucks have been popular in China for 20 years, specifically referring to concrete pump trucks with 39 meters and below. Small concrete pump truck is a kind of construction equipment that transports concrete through the pipeline by pressure, and the pumping construction conveying distance is long, and the conveying volume is large in the unit, which is mainly used for concrete conveying work of large-scale concrete projects such as high-rise buildings, high-speed, and overpasses. It is an ideal equipment in the concrete transportation equipment, which can complete vertical conveying and horizontal conveying continuously at one time.

In the construction site where it is narrow or has many obstacles, it is often difficult for large pump trucks to get close to the construction site and cannot pump concrete. At this time, the relatively small concrete pump truck can shuttle through the construction site, arrive at the destination construction site, and perfectly complete the pumping construction task.
