Cement Grouting Pump Machine
Structure of Cement Grouting Pump Machine:
The cement grouting pump machine's body is a sealed variable speed box, which is mainly composed of input shaft, intermediate shaft, variable speed shaft, gear and so on. Crank connecting rod mechanism, and by the speed change handle, pull bar, fan gear, clutch rod, etc., the gear, clutch control mechanism composed of three parts.
The input shaft is hollow, and the input end is equipped with a coupling, which is connected with a pulley clutch. The middle shaft is hollow spline shaft, and the input shaft is on the same axis, the shaft end is installed with the clutch handle shell, when the handle rotates upward will drive the eccentric shaft rotation, so as to squeeze the long push rod, short push rod and push disk, compression clutch spring, clutch separation. The variable speed shaft is a spline shaft, which is equipped with two double sliding gears. The position of the sliding gear is controlled by the variable speed handle to achieve four-level variable speed. The specific gear position is shown on the plate above.

Structure of Cement Grouting Pump Machine:
PU Grouting Machine is mainly composed of pump body, pump frame, air chamber, shock-resistant pressure gauge, motor, V-belt and pulley cover.
The installation foundation of cement grouting pump should be smooth and not inclined.
The pump is fixed on the foundation with the foot screw to prevent the vibration of the pump during operation.
Preparations before pumping:
After the pump has been stopped or reinstalled for a long time, the following preparations must be made before starting.
1. Check whether there is enough lubricating oil in each part.
2. Check whether the suction pipe of the filter is unblocked.
3. Check whether there is obstruction in the movement of each part.
4. Check the accuracy and reliability of the transmission mechanism.
5. Check the looseness of fasteners, especially the screw tightening of rubber piston locking nut, cross head and piston rod connection thread.
6. Check the suction height of the pump. The maximum suction height of the pump should not exceed 2.5 meters in areas below 1000 meters above sea level. In areas above 1000 meters above sea level, the suction height of the pump should be reduced according to the local atmospheric pressure reduction.
7.Check the position of the filter immersed in the mud tank. Generally, the mud level should be below 0.3-0.5 meters, and the filter should be no less than 0.5 meters away from the bottom of the mud tank.
