Mud pump often encountered failure and treatment

Pump Valve Trading News mud pump often encountered faults and treatment methods 1, mud pump failure: slow pump water causes: large gap between the front liner and the impeller, the water outlet pipe can not seal the air, empty the full solution: adjust the gap, adjust Outlet pipe, installation of vacuum device 2, mud pump failure: pump vibration causes: pump shaft and diesel engine (or motor) misalignment, impeller imbalance, bearing damage Solution: adjust concentricity, impeller for balance testing, replacement of bearings 3, Slurry pump failure: The pump is not water-absorptive Causes: Insufficient water for pumping, air in the pump cannot be exhausted, air leaking from the suction pipe, large gap between the front liner and the impeller Solution: Continue to infuse diversion, check if the pipeline leaks, and adjust the impeller and front liner. Plate gap 4, mud pump failure: low water pressure, small flow rate Causes: Air in the pump, large clearance between the impeller and the front liner, clutch not tightly closed, wear of the impeller or liner Solution: Drain the air in the pump, adjust the gap , Adjust the clutch friction plate clearance, replace the impeller or lining plate 5, mud pump failure: faster wear of the impeller journal cause: high-pressure pump low head, dislocation, The pump shaft and the rear cover do not have the same solution: Replace the high pressure pump above the head of the mud pump, replace the packing, adjust the concentricity 6, and the mud pump is faulty: the pump wears quickly. Cause: The construction environment (large particles) is poor, and the conveying distance is long. Inlet water line length solution: replace the sand field, add afterburner units, shorten the inlet pipe length and reduce cavitation
