Description

Technical Field

[0002] A centrifugal pump is a pump that transports liquids by the centrifugal force generated by the rotation of the impeller. A centrifugal pump works by using the centrifugal motion of water caused by the rotation of the impeller. Before starting the water pump, the pump casing and the suction pipe must be filled with water, and then the motor is started so that the pump shaft drives 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 casing.

[0003] Traditional centrifugal pumps are generally composed of a motor and a pump, which are connected by a coupling. The temperature of the motor will rise during long-term use, generating a large amount of heat, thereby reducing the service life of the centrifugal pump. Therefore, traditional centrifugal pumps will add a cooling fan to the motor casing for heat dissipation. However, the cooling effect of the cooling fan is limited and still cannot meet the needs of long-term use, resulting in the phenomenon that the performance of the centrifugal pump itself is not stable enough.
