Manual Cement Grouting Pump
Description of Manual Cement Grouting Pump:
Manual cement grouting pump is especially suitable for treating various soft ground grouting operations. It is a three-cylinder single-acting round-trip plunger pump (see Figure 1), with four gears, which can mainly be used for hydraulic impact drilling in hole depth of 1000 meters, screw drilling in hole depth of 15000 meters, turbine drilling in hole depth of 2500 meters, and common core drilling in hole depth of 15000 meters. Crankcase and gearbox integrated design, so the pump not only reliable performance, wearing parts of a long life, and small volume and light weight, good decomposition, easy to move mountain, is the ideal equipment for geological exploration, but also engineering construction drilling, sugar, wine dike grouting and other uses.

Structure of Manual Cement Grouting Pump:
Manual Cement Grouting Pump 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 of Manual Cement Grouting Pump:
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.
