Analyze the cause of the mud pump failure and its troubleshooting

Mud pump is generally used mainly in rural areas as river mud, manure, river water, slurry feed, suction and irrigation, instead of shouldering the pick and bear, and for drainage, drought purposes, can also be car head, the river mud, fertilizer production, Can also be used as a simple flow of rural fire pumps, fish ponds can also be used for clear ponds, ponds and oxygen. It can also be used in municipalities, chemical industry, printing and dyeing, medicine, shipbuilding, casting, food and other industries aspirated thick liquid, dirty liquid, paste, quicksand and urban river flow of sludge can be used as a mine exclusion of small gravel Of fluid. If the high-pressure water pump, water gun with the composition of hydraulic mechanized earthwork unit can be used for land leveling, river, ponds, air defense, underground excavation and other projects such as engineering. Mud pump failure reasons and troubleshooting Mud pump failure 1: The pump is not absorbent Reason: insufficient filling water, the pump air can not be discharged, the suction pipe leaks, the front liner and impeller clearance big solution: continue to pour water, check whether the pipeline Leakage, adjust the gap between the impeller and the liner mud pump failure 2: Pumping water 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 Vacuum pump 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 tight, impeller or liner wear Solution: empty the pump gas, adjust the gap , Adjust the clutch friction plate gap, replace the impeller or liner mud pump Fault 4: pump vibration Cause: pump shaft and diesel engine (or motor) is not the heart, impeller imbalance, bearing damage Solution: adjust the concentricity, impeller balance test, Replace the bearing mud pump failure 5: impeller shaft wear fast reason: high-pressure pump head low, packing root dislocation, the pump shaft and the back cover do not mind to solve Replacing the high-pressure pump above the head of the mud pump, replacing the packing, adjusting the concentric mud pump failure 6: Pump wear fast Cause: poor construction environment (large particles), long distance, inlet pipe length Solution: , Add afterburner unit, shorten the length of the inlet pipe to reduce cavitation
