Pressure Grouting Machine
Work Preparation of 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 the sufficiency of lubricating oil in the gearbox
(lubricating oil should be injected into the gearbox to the viewing
hole of the oil window when it is first used).
2. Check the fastening and loosening of all parts, especially the
screw tightening of rubber piston locking nut, cross head and tie
rod. Whether the moving parts are blocked or not, and whether the
rotation is flexible.
3. Check whether the filter, suction pipe and discharge pipe are
unblocked.
4. Check whether the joints of the pipelines are firm and tight,
whether there is leakage or leakage.

Structure of Pressure Grouting Pump:
Chemical Grout Injection 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 Pressure 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.
