The whole machine

Secondary constructional column pump, also known as small fine stone delivery pump, is widely used in some special construction environments, such as railway and highway tunnels, diversion tunnels, culverts, bridge opening and other caves, including water conservancy projects, hydropower projects, slope support, underground construction operations, foundation filling projects, constructional column pouring of large-scale podium buildings and so on.

Main feature

1. The mortar pump adopts double-cylinder piston type, electro-hydraulic combined control and S-tube valve distribution. It has the advantages of stable system, simple control system, convenient operation and less maintenance.
2. The use power of the pump is very small, and it only needs to be equipped with the smallest generator to work without power supply.
3. It is the smallest concrete pump in China and the only choice for many narrow construction environments.
4. The pump is light in weight and easy to move.
5. High pump configuration, full hydraulic operation, stable performance, compact structure, low failure rate and long service life.
6. Pumps are affordable miniature mortar pumps.
7. High pumping pressure and long pumping distance.
8. Used for structural column pouring, with good continuity and high conveying efficiency, which is hundreds of times that of artificial pouring concrete.
9. The distribution valve adopts advanced S-tube valve, which has good sealing performance and simple and reliable structure. The spectacle plate and wear-resistant ring are made of wear-resistant cast iron, which has good wear resistance, long service life and convenient replacement. The wear-resistant ring adopts a mechanism that can automatically compensate the gap.
10. The control mode is electro-hydraulic control, with simple operation, stable operation and low noise; It has perfect electro-hydraulic overload protection and instrument display system; Have the function of reverse pump operation; The operation is safe and reliable, and the blockage fault is easy to be removed and the maintenance is convenient.
11. Contactor, button switch and other electrical components, the protection level can reach IP65, and the control circuit is simple and reliable.
12. The stirring device is sealed and reliable, and it is not easy to leak slurry; The structure of the stirring blade is reasonable, which greatly improves the suction efficiency.
13. The main seal adopts PARKER's high-quality seal, which prevents the internal and external leakage of the hydraulic system.
14. The hopper screen is equipped with a vibrating motor to ensure sufficient blanking.
