Hand Grout Pump
Description of Hand Grout Pump:
BW150 grouting pump is a horizontal three-cylinder reciprocating
single-acting piston pump, which is mainly used in road, bridge,
dam, mine and high-rise building grouting construction. Eight
different working pressures and flow rates can be changed.
Technical parameters of Hand Grout Pump:
| Cylinder number | 3 |
| Bore diameter | 70mm |
| Piston stroke | 70mm |
| Suction height | 2.5 meter |
| Diameter of suction pipe | 50mm |
| Diameter of outlet pipe | 32mm |
| Motor power | 7.5kw |
| Main shaft speed | 1450 r/min |
| Working pressure | 7 Mpa |
Structure of Hand Grout Pump:
Hand 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.
