Cement Pressure Grouting Machine

Decription of Cement Pressure Grouting Machine:

1. During the operation of the grouting pump, it is forbidden to carry out any repair, cleaning and oiling of the gear box.
2. It is forbidden to take down the protective cover of grouting pump without stopping and work without installing the protective cover.
3. It is forbidden to overpressure grouting pump and work for a long time.
4. When the grouting pump pressure does not drop to zero, it is forbidden to remove the air chamber, pressure gauge and pipeline.
5. When repairing and checking electric appliances such as motors, wires and pressure gauges, cut off the power supply.
6. For the grouting pump with casters, the casters should be adjusted to separate from the ground to prevent swimming during transportation and operation.

Technical Parameters of Cement Pressure Grouting Machine:

Structure of Cement Pressure Grouting Machine:

Cement pressure 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 of Cement Pressure Grouting Machine:

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.
