Concrete Pumping Equipment

Working Principle​
A concrete pump is composed of several key components, namely the pump body, delivery pipeline, and power unit. Its operating principle is based on the reciprocating motion of a piston. During the suction stroke, the piston moves backward, creating a negative pressure within the pump body. Under the action of atmospheric pressure, concrete is drawn into the cylinder of the pump body through the inlet. In the subsequent pushing stroke, the piston moves forward, squeezing the concrete in the cylinder out and forcing it to flow along the delivery pipeline to the designated location. This mechanical - force - driven method of concrete conveyance enables long - distance and high - elevation transportation.​

• Concrete pump tubes are characterized by high pumping pressure and large displacement. Generally, their pumping pressure can reach dozens of megapascals, and the displacement can be several tens to over a hundred cubic meters per hour. This enables them to adapt to construction projects of different scales and conditions.
• Moreover, the delivery pipelines of towable concrete pumps can be flexibly arranged according to actual construction requirements. Whether it is vertical upward, horizontal extension, or a curved path, they can effectively transport concrete to the target location.
• In addition, modern new concrete pumps have seen a significant improvement in automation.
• They are easier to operate, allowing for precise control of the pumping speed and volume, reducing human - operation errors and improving the stability and reliability of construction.

Concrete delivery with pumps find extensive use in various large - scale construction projects.

In the construction of high - rise office buildings, for instance, there is a need to transport concrete to floors dozens or even hundreds of meters above the ground.

The concrete placing pump, with its powerful pumping capacity, can accurately deliver the concrete to the construction site, ensuring the smooth progress of the building structure pouring.

In bridge construction, especially in the pouring of piers for long - span bridges, due to the complex terrain at the construction site, traditional concrete transportation methods often fall short.

The electric concrete pump can lay pipelines to directly transport concrete from the ground or the mixing plant into the formwork of the piers, guaranteeing the continuity and integrity of concrete pouring, thus enhancing the quality and efficiency of bridge construction.​

Portable Cement Screw Conveyor

A cement screw conveyor is mainly used for cement conveying in concrete mixing plants.

Portable cement screw conveyor is a new type of screw conveyor. Compared with the traditional shaft screw conveyor, it has the following characteristics:

1 Thickened body: thickened steel, high hardness and durability

2 Universal ball: the feed port can be adjusted in angle, and the flange size is customized according to the size of the equipment's discharge port

3 Discharge port: round tube type discharge port, fast discharge speed

High-efficiency transportation: The helical screw conveyor adopts a new type of suspended intermediate hanging bearing frame, which increases the material transportation space and reduces logistics resistance. In addition, the small diameter, high speed, variable pitch and other designs ensure smooth, fast and uniform feeding.

Random layout: The outer shell of the multi screw conveyor adopts a U-shaped groove design for easy maintenance. The whole, whether horizontal or at a large angle, can be continuously transported. It can be directly connected and fixed with the supporting equipment without the need for a foundation, making full use of space, and is very convenient to move and disassemble.

Diversified connection: The feed and discharge ports can be connected in various forms such as flange connection, bag connection, bag boom connection, universal interface connection, etc.

Reliable sealing: The connection of the outer shell pipe of the screw pipe conveyor is equipped with an anti-seepage device, and the process hole has also been carefully improved to avoid the occurrence of blockage and machine suffocation caused by cement agglomeration in the pipe due to rainwater infiltration.

No need to add oil: Since the automatic screw conveyor adopts a novel intermediate bearing material, it can reduce friction, be wear-resistant and self-lubricating. Even if it is used for a long time, no lubricating oil needs to be added, which can avoid the side effects of grease and cement mixing on the sleeve and shaft.

Special reducer: The reducer specially made by our company is advanced and reasonably designed, with the advantages of small size, light weight, large torque, fast speed, no oil leakage, no noise, etc., and is equipped with a stop structure, which can be fully suitable for thrust conveying at large inclination angles.
