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

Mud pumps are generally used in the rural areas as river mud, excrement, river water, and slurry feed to suck and water, instead of picking shoulders and shoulders, as well as for drainage and drought resistance, they can also be used to carry car heads, river mud, and compost production. It can also be used as a simple-flow 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. The fault mud and Remedy

Slurry pump failure 1: Pump does not absorb water

Causes: Insufficient diverted water, no air in the pump, leakage in the suction pipe, large gap between the front liner and the impeller

Solution: continue to divert water, check the pipeline for air leakage, and adjust the gap between the impeller and the front liner.

Slurry Pump Fault 2: Pump Slow Water

Cause: Large gap between the front liner and the impeller, the outlet pipe cannot seal the air, and the exhaust is full.

Solution: adjust the gap, adjust the outlet pipe, install the vacuum device

Slurry pump failure 3: low water pressure, small flow

Reasons: There is air in the pump, large clearance between the impeller and the front liner, the clutch is not tightly closed, and the impeller or liner wears

Solution: Drain the gas in the pump, adjust the clearance, adjust the clutch friction plate clearance, replace the impeller or liner

Slurry Pump Fault 4: Water Pump Vibration

Reason: The pump shaft is different from the diesel engine (or motor), the impeller is not balanced, and the bearing is damaged

Solution: adjust the concentricity, impeller balance test, replace the bearing

Slurry Pump Fault 5: Impeller Shaft Wears Fast

Reason: Low head of high pressure water pump, misplaced packing, different shafts of pump shaft and back cover

Solution: Replace the high pressure pump above the head of the mud pump, replace the packing, adjust the concentricity

Slurry Pump Fault 6: Pump Wears Fast

Reason: poor construction environment (large particle size), long conveying distance, long inlet pipe length

Solution: Replace the sand yard, add afterburner units, and shorten the length of the inlet pipe to reduce cavitation
