[0002] The existing centrifugal pump is a device used for conveying water. Before starting the centrifugal pump, the pump body and the suction pipe must be filled with water, and then the motor is started to make the pump shaft drive the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller and flows into the water pressure pipeline of the water pump through the flow channel of the volute pump body.
