Description of high pressure grouting pumps
This series of high pressure grouting pumps is a light high pressure pump that has been carefully developed to meet the growing high pressure grouting technology. The latest generation of products that can pump medium such as clear water and high-density cement slurry, and equipped with a speed control mechanism, can be used as a variable pump. It has the characteristics of reasonable parameters, advanced technology, reliable quality, excellent performance and beautiful appearance.
Working medium of grouting pumps
The working medium must be filtered through a filter of 20 mesh or more to filter out harmful solid particles. If there are more solid particles in the medium, increase the number of filtrations. The common failures caused by poor filtration are as follows:
- Since the hydraulic end of the mud pump is sealed as rubber, the solid particles are pressed into the rubber by the valve plate under high pressure. If the particles are large, the valve plate will be padded, causing the seal to fail and damage the valve plate and the valve seat.
- If the particles are small, but the quantity is large, after accumulating to a certain extent, the valve plate will be padded, causing the seal to fail and damage the valve seat and the valve plate.
- Because the gap between the valve plate and the limit sleeve is small, if the larger particles are squeezed in, the valve plate can be stuck, causing the pump to work abnormally and damage the valve seat.
- Users of cement slurry should note: due to the different cement producers used, the size and quantity of iron beans in the cement are different. Please use a suitable filter according to the situation to ensure the high pressure pump can work normally.
Main function Of high pressure grouting pump
High-pressure grouting pump is mainly used for soft ground treatment, high-pressure jet grouting; high-pressure water jet assists rock breaking; coal mine hydraulic props for underground hydraulics; anchored hydraulic expansion metal pumping pump for high-pressure water; underground large-scale pipeline dredging Cleaning; chemical pump; high-pressure water jet horizontal through hole drilling; other uses grouting pump;
