The self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline, and it is only necessary to ensure that there is a quantitative suction liquid stored in the pump body before work. Different liquids can use different material self-priming pumps. The working principle of the self-priming pump is to fill the pump casing with water before the pump starts. After starting, the impeller rotates at high speed to make the water in the impeller channel flow to the volute. At this time, the inlet forms a vacuum, which makes the water inlet check door open, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.

In the existing self-priming pump, the water inlet pipe may be blocked by impurities during operation, so that the self-priming pump cannot work normally, and it needs to be cleaned before it can work, which affects the working efficiency of the self-priming pump.
