Electric Grout Pump
Description of Electric Grout Pump:
Electric grout pump can be used as a cement grouting pump in
foundation treatment engineering. The cement ratio of cement slurry
can reach 1:1, and it has small size, compact structure, and can
prevent collapse. It is easy to install, disassemble and carry. The
electric grout pump can be used as a matching equipment for 1000m
large diameter drilling rig with four-step displacement.
Technical parameters of Electric Grout Pump:
| Cylinder number | 3 |
| Bore diameter | 80mm |
| Piston stroke | 100mm |
| Diameter of suction pipe | 64mm |
| Diameter of outlet pipe | 32mm |
| Motor power | 15kw |
| Main shaft speed | 1450 r/min |
| Working pressure | 6 Mpa |
Structure of Electric Grout Pump:
Electric Grout 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:
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.
