Mortar pump troubleshooting - medium pump valve

Mortar pump failure 1: The pump does not absorb water: the perfusion water is not enough, the pump air can not be discharged, the suction pipe leaks, the front liner and the impeller gap are large. Treatment: Continuously injecting water, introspecting whether the pipeline can leak, and conditioning the impeller The slurry pump with the front liner is faulty. 2: The slow water on the pump is caused by: the gap between the front liner and the impeller is large, the outlet pipe can not seal the air, and the emptying method is full: conditioning gap, conditioning the water pipe, and installing the vacuum installation Mortar pump failure 3: The outlet pressure is small, and the flow rate is small: the air in the pump, the gap between the impeller and the front liner is large, the separation of the gathering device is not tight, and the impeller or the liner is worn. The air in the pump is drained, the conditioning gap is Conditioning separation of the friction plate gap of the gathering device, changing the impeller or the lining mortar pump failure 4: The vibration of the pump is caused by the difference between the pump shaft and the diesel engine (or the motor), the impeller is not compliant, and the bearing damage treatment method: conditioning and centrifugation, impeller for equalization test Change the bearing mortar pump fault 5: Impeller journal wear fast edge: high pressure pump head low, packing misalignment, pump shaft and back cover disparity treatment: change is higher than Mud pump lift head high pressure pump, change packing, conditioning and heart rate mortar pump failure 6: pump wear fast edge: construction situation (granularity) is poor, far-reaching interval, long water inlet pipe treatment method: change the battlefield, add afterburner Shorten the length of the inlet pipe to reduce cavitation
