Analysis of the causes of the failure of the mud pump in Haitan Pump and its remedies

Mud pumps are generally used in rural areas as river mud, excrement, river water, and slurry feed to provide water for irrigation, instead of picking shoulders for people, as well as for drainage and drought resistance, it is also possible to carry car heads, river mud, and compost production. It can also be used as a simple fire pump in rural areas. It can also be used as a fish-to-water clear pond, and oxygen in fish ponds. Can also be used in municipal, chemical, printing and dyeing, pharmaceutical, shipbuilding, foundry, food and other industries to pump thick liquids, contaminated liquids, pastes, quicksand and flowing sludge in urban rivers, etc. can be used as coal mines to exclude gravel and small gravel The fluid. If high-pressure water pumps and water guns are combined to form a hydraulic mechanized earthwork unit, they can be used for excavation and transportation of land leveling, river courses, ponds, air defense, and underground projects. Mud pump failure causes and remedies.

Slurry pump failure 1: Pump does not absorb water

Reason: perfusion enough water, air can not be discharged in the pump, the suction pipe leak, front liner and impeller large gap Solution: Continue filling water, check the pipe leaks, the front plate and the gap adjusting impeller <br> <br > mud pump fault 2: slow pump Sheung Shui
Reason: a large front liner and impeller clearance, the air outlet duct is not sealed, evacuated full solution: gap adjustment, adjusting the water outlet pipe, a vacuum device mounted <br> <br> mud Fault 3: Small water pressure, flow small

Causes: 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 clearance, adjust the clearance of the clutch friction plate, replace the impeller or the liner
Slurry Pump Fault 4: Water Pump Vibration

Causes: Concentricity between pump shaft and diesel engine (or motor), imbalance of impeller, bearing damage Solution: Adjust concentricity, balance test impeller, replace bearing
Slurry Pump Fault 5: Impeller Shaft Wears Fast

Reasons: High head of low-pressure pump, dislocation of packing, misalignment of pump shaft and back cover. Solution: Replace the high pressure pump above the head of mud pump, replace packing, adjust concentricity
Slurry Pump Fault 6: Pump Wears Fast

Reasons: poor construction environment (large particles), long transportation distance, long inlet pipe Solution: Replace the sand yard, add afterburner units, shorten the length of the inlet pipe, reduce the cavitation double-stage water ring vacuum pump, double-stage rotary vane vacuum pump , Stainless steel submersible sewage pump, non-clogging sewage pump, stainless steel self-priming sewage pump, vertical pipeline sewage pump.
