Mud pump failure 1: The pump is not absorbent Cause: Insufficient filling water, the pump air can not be discharged, the suction pipe leaks, the front liner and the impeller clearance big solution: continue perfusion water, check the pipeline is leaky, adjust the impeller and the front Liner gap mud pump failure 2: Pumping water is slow Cause: The front liner and the impeller gap, the outlet pipe can not seal the air, emptying over Solution: Adjust the gap, adjust the outlet pipe, install the vacuum device Mud pump failure 3 : The water pressure is small, the flow is small Reason: the pump air, the gap between the impeller and the front liner, the clutch is not closed, the impeller or liner wear Solution: empty the pump gas, adjust the gap, adjust the clutch friction plate clearance, Replace Impeller or Liner Mud Pump Fault 4: Pump Vibration Cause: The pump shaft is not the same as the diesel engine (or motor), the impeller is unbalanced and the bearing is damaged Solution: Adjust the concentricity and impeller for balance test, replace the bearing mud pump Fault 5: Impeller shaft wear fast cause: high-pressure pump head low, packing root dislocation, the pump shaft and the back cover is not the heart Solution: replace the high Slurry pump head high pressure pump, replace the packing, adjust the concentric mud pump failure 6: Pump wear fast reason: the construction environment (large particles) is poor, the transmission distance, the inlet pipe length Solution: Change the battlefield, add afterburner , Shorten the length of the inlet pipe to reduce cavitation
