Mortar pump failure causes and solutions: Mortar pump failure 1: Pump not absorbent reasons: inadequate perfusion irrigation, pump air can not be discharged, the suction pipe leaks, the front liner and the impeller gap large approach: continuous infusion diversion, Reflect the pipeline can leak, conditioning the impeller and the liner of the gap between the mortar pump failure 2: Pumping slow edge of the water by: the front liner and the impeller gap, the outlet pipe can not seal the air, emptying Full treatment: conditioning Gap, conditioning effluent pipe, the installation of vacuum pump mortar 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 large, splitter closure is not tight, impeller or liner wear treatment : Drain the gas in the pump, adjust the gap, adjust the separation gap of the gathering friction plate, change the impeller or liner mortar pump Fault 4: Pump vibration reason: The pump shaft and diesel engine (or motor) divergent heart, impeller is not balanced, bearing damage treatment Approach: conditioning fit, the impeller for a balanced test, replacement bearing mortar pump failure 5: impeller hub wear fast edge by: high-pressure pump head low, packing dislocation, Disadvantage of the pump shaft and the back cover approach: to change the high pressure pump higher than the head of the mud pump, change the packing, conditioning mortar pump at the heart of trouble 6: pump wear fast margin by: the construction of the situation (large particles) Long way to deal with water pipes: Change the battlefield, add afterburner, shorten the length of the inlet pipe to reduce cavitation
