Centrifugal pump out of water or sudden stop water causes and solutions

Posted on

Pumps common faults, in general, can be divided into two types of hydraulic faults and mechanical faults. Failure, should be promptly checked and ruled out, not to make the machine "sick" work. Troubleshooting procedures are: to clarify the phenomenon - → Analysis of the reasons - → be excluded.

    Centrifugal pump in operation, the pump out of water.

Reasons: Remedy:

Submerged suction pipe is not deep enough, the pump inhalation 1. Increase the length of the suction pipe, put a piece of wood on the water to prevent air into the water pipe
Water pipe joints Department leaks, leaking 2. Tighten the connection screws or replace the pad suction pipe or impeller with water and debris 3. Clear water debris high water transport 4. Lower the water delivery height or off the valve on the small pressure pipe Seal packing leak 5. Tighten the gland or replace the filler water lift is too high 6. Adjust suction head lift or off valve speed is not enough Adjust the tightness of the drive belt Centrifugal pump in operation, the pump suddenly stopped water.

Reasons: Remedy:

Water pipe suddenly blocked by debris 1. After stopping to remove clogged debris was sucked or cluttered debris 2. After shutdown, remove the pump, remove debris or replace the impeller nozzle inhalation of a large number of air 3. To deepen the submerged suction pipe depth

All in all, the causes of pump failure are many, to be careful analysis, do not be too busy dismantling parts. Should follow the "first external, internal" principle check to find out the reason, "the right medicine," troubleshooting.
