[0002] A centrifugal pump refers to a pump that transports liquids by the centrifugal force generated when the impeller rotates. When the motor starts, the pump shaft drives the impeller and water to rotate at a high speed. Under the action of centrifugal force, the water is thrown to the outer edge of the impeller and flows into the pressure water pipeline of the water pump through the flow channel of the volute pump casing, thereby realizing the transportation of liquids.
