The two stage structure pump is the place where the large scale stone pump can not reach. Fine stone pumpMany outstanding technologies have been used in concrete pumps and have been patented.It is a domestic fine aggregate concrete conveying equipment.Compared with the construction method of the elevator, the use of fine stone concrete pump is not easy to damage the ground heating pipe in the construction of the fine concrete or mortar backfill in the floor heating project. It can greatly improve the construction efficiency and reduce the labor intensity of the workers. The two stage structure pump is the place where the large scale stone pump can not reach, and the work is done without working place.This is the characteristics and advantages of the micro fine stone pump, and the micro stone pump can achieve the performance of the large scale stone pump.Materials for transporting large sized stone pumps can also be transported easily.This is a very advantageous feature.It is quite technical to achieve such a level in small volume. 1. the two grade special mortar grouting pump can realize the transportation of fine sand concrete and mortar for long distance high-rise buildings. 2, the distribution valve adopts advanced S type pipe valve, which has good sealing performance and simple and reliable structure.The eye plates and floating cutting rings are made of cemented carbide, with good wear resistance, long service life and convenient replacement.The cutting ring adopts automatic compensation gap structure. 3, the control mode is electro hydraulic control, which has a perfect electro-hydraulic overload protection and instrument display system. It has the function of anti pump operation, easy to exclude the blockage fault, and the pumping speed can be adjusted to meet various working conditions. 4. centralized lubrication system starts automatically by program, stops and runs time, effectively prolongs the service life of rotating parts. 5, electrical components such as contactor and pushbutton switch, the protection level can reach IP65, PLC control is adopted, the operation is reliable, the control circuit is simple, the switch is installed in the electrical appliance box, and the operation is convenient. 6. the main seal is sealed to prevent internal and external leakage of the hydraulic system. 7. low feed height, easy to assemble into a combined unit.It is equipped with lifting and guiding wheels, which can flexibly and conveniently locate and move.
