Mud pump in the use of the process, which is likely to occur when suction pump does not suction water, suction water slow or pump vibration situation, these water absorption is what caused the failure of it
1. Pump suction is not water, the main reason is not enough water, the pump can not discharge air, water pipe leakage, the front guard plate and the impeller clearance is too large, etc.. If the high-pressure water pump and vacuum pumping device working sand pump suction water in the sand outlet there is a small amount of water overflow, even if the sand pump stops water does not stop, then should be the sand suction pipe blockage.
2. Pump water slowly, mainly because the former liner and impeller clearance, the outlet pipe can not seal the air, emptying slowly etc..
3. Pump vibration, the main cause of pump shaft and motor (or diesel) is not concentric, uneven impeller, bearing damage, etc..
