简体中文1. The working principle of the self-priming pump is: fill the pump casing with water before starting the pump (or there is water in the pump casing itself). After starting, the impeller rotates at a high speed to make the water in the impeller channel flow to the volute. At this time, the inlet forms a vacuum, so that the water inlet check door opens, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.
