Mud pump common faults and maintenance methods

Mud pump is a single-stage single-suction centrifugal pump is used in mining, paper making, printing and dyeing, environmental protection, graphite, mica, gold, ceramic, oil refining, petroleum, chemical industry, farms, saltworks, iodine, dyeing, brewing, food, chemical fertilizer, coking mill plant, building, marble factory, mine, mud, sand, muddy ponds, sludge pond and dreggy liquid to send thick pulp thick liquid, charging and aerosols in sewage, also can make coal mine drainage and the fluid containing clods. If with high pressure water pump, water gun, hydraulic mechanized earthwork unit, it can be used in land leveling, dredging of river and pond, chiseling, excavation and transportation of small water conservancy engineering, as well as the city's air defense project, the following projects.

Mud pump common faults and pump maintenance methods:

Mud pump failure 1: don't pump suction

Reason: perfusion inadequate water diversion, air in the pump can't eduction, suction pipe leakage, liner and impeller clearance before

Solution: to continue to infusion water diversion, check whether the pipe is air, adjust the impeller and the former plate gap

Mud pump fault 2: pump water slowly

Reason: big, liner and impeller clearance before can't full sealed air, emptying water pipes

Solution: adjust the clearance, adjust the water pipe, install vacuum device

Mud pump failure 3: the water pressure and flow rate is small

Reason: pump with air, impeller and top plate gap, clutch closure is not tight, impeller or liner wear

Solution: gas inside the drain pump, adjust clearance, clearance, replacement of adjusting clutch friction impeller or lining

Mud pump fault 4: the pump vibration

Reason: the pump shaft with diesel engine (or motor) different heart, impeller imbalance, bearing damage

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

Mud pump fault 5: quick wear of impeller shaft neck

Reason: low dislocation, packing, high pressure water pump head pump shaft and the rear cover different heart

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

Mud pump failure 6: quick wear of pump

Reason: poor construction environment (particles) and long conveying distance, suction culvert

Solution: replace the battlefield, add strength, shorten the length of inlet pipe to reduce cavitation
