Grout injection Pump
Description of Grout Injection Pump:
Grout injection pump BW-250 type is a horizontal three-cylinder reciprocating single-acting piston pump, which is one of the main supporting equipment for geological exploration. Its main function is to supply flushing fluid (mud or clear water) to the borehole during core drilling, so that it can circulate in the borehole, so as to carry debris back to the ground, cool and lubricate drill bits and drilling tools, and protect the borehole wall from collapse.
Technical parameters of Grout Injection 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 Grout Injection Pump:
Grouting pump 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:
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.
