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 municipal, 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 coal mine exclusion of small pebbles 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 causes and troubleshooting

Slurry Pump Fault 1: The pump is not absorbing water

Reason: perfusion is not enough water, pump air can not be discharged, suction pipe leaks, front liner and impeller gap

Solution: continue perfusion water, check whether the pipeline leak, adjust the gap between the impeller and the front liner

Mud pump failure 2: pump on the water slow

Reason: the front liner and impeller gap, the water outlet pipe can not seal the air, emptying full

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

Mud pump failure 3: water pressure is small, small flow

Reason: pump air, the gap between the impeller and the front liner large clutch tight closed, 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

The reason: the pump shaft and diesel engine (or motor) do not mind, impeller imbalance, bearing damage

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

Mud pump failure 5: impeller shaft wear fast

The reason: high-pressure pump head low, dislocation, pump shaft and the back cover is not the heart

Solution: Replace the pump higher than the head of the mud pump, replace the packing, and adjust the concentricity

Mud pump failure 6: Pump worn fast

Reason: The construction environment (large particles) poor transmission distance, inlet pipe length

Solution: Change the battlefield, add afterburner, shorten the length of the inlet pipe to reduce cavitation
