Mud pump often encountered failure and treatment

1. Slurry pump failure: Slow pumping water Cause: Large gap between the front liner and the impeller, the water outlet pipe cannot seal the air, empty the full solution: adjust the gap, adjust the outlet pipe, install the vacuum device 2, mud pump failure: Causes of water pump vibration: Concentricity between pump shaft and diesel engine (or motor), imbalance of impeller, bearing damage Solution: Adjust concentricity, balance test for impeller, replacement of bearing 3, mud pump failure: Pump does not absorb water Cause: Insufficient water for perfusion, The air in the pump cannot be discharged, the suction pipe leaks, and the gap between the front liner and the impeller is large. Solution: Continue to infuse diversion, check if the pipeline leaks, and adjust the gap between the impeller and the front liner. 4. The mud pump is faulty: the pressure of the outlet water is small and the flow rate Small reason: There is air in the pump, large gap between the impeller and the front liner, the clutch is not tightly closed, and the impeller or liner wears. Solution: Drain the air in the pump, adjust the gap, adjust the clutch friction plate clearance, replace the impeller or liner 5 , mud pump failure: rapid wear impeller wheel causes: high-pressure pump low head, root dislocation, the pump shaft and the rear cover distracted solution: replace the mud High-pressure pump head pump, replacement packing, adjust concentricity 6, mud pump failure: rapid wear and tear of the pump Cause: poor construction environment (large particles), transmission distance, long inlet pipe Solution: Replace the sand field, add afterburner Units, shorten the inlet pipe length, reduce cavitation
