Mud pump accessories manufacturer introduction mud pump troubleshooting
Mud pump vibration
Cause: the pump shaft and diesel engine (or motor) are not centrifugal, the impeller is unbalanced, and the bearing is damaged;
Solution: adjust concentricity, conduct impeller balance test, and replace bearings.
Cause: the gap between the front cylinder liner and the impeller is large, and the exhaust pipe cannot seal air, so the exhaust volume is large.
Solution: adjust the clearance, adjust the outlet pipe, and install the vacuum pumping device.
Cause: insufficient water filling and diversion, the air in the pump cannot be discharged, the suction pipe leaks, and the gap between the front cylinder liner and the impeller is large;
★ original solution: continue to fill the water, check whether the pipeline leaks, and adjust the gap between the impeller and the front lining plate.
Low pressure and flow
★ cause: there is air in the pump, the gap between the blade and the front lining plate is large, the clutch is not closed tightly, and the blade or lining plate is worn;
Solution: drain the gas in the pump, adjust the clearance between the clutch friction plates, and replace the impeller or bushing.
Rapid wear of pump
★ reasons: poor construction environment (large particles), long transportation distance and long water inlet pipeline;
Solution: replace the sand field, increase the afterburner, shorten the length of intake pipe, and reduce cavitation.
Rapid wear of impeller Journal
★ cause: the high-pressure water pump has low speed, the packing is misaligned, and the pump shaft is not concentric with the rear cover;
Solution: replace the high-pressure pump higher than the mud pump head, replace the packing and adjust the concentricity.
