The self-priming pump is a self-priming centrifugal pump with the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. The pipeline does not need to be installed with a bottom valve. Before working, it is only necessary to ensure that a certain amount of liquid is stored in the pump body. Different materials of self-priming pumps can be used for different liquids.
Description
Working principle
The working principle of the self-priming pump is that the pump casing is filled with water before the pump is started (or there is water in the pump casing itself). After starting, the impeller rotates at high speed to make the water in the impeller groove flow to the volute. At this time, a vacuum is formed at the inlet, causing the water inlet check valve to open, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller groove.
