When the centrifugal pump is working, it relies on the impeller that rotates at a high speed, and the liquid obtains energy under the action of inertial centrifugal force to increase the pressure. Before the centrifugal pump is working, the pump body and the inlet pipeline must be filled with liquid medium to prevent cavitation.
When the impeller rotates rapidly, the blade causes the medium to rotate rapidly, and the rotating medium flies out of the impeller under the action of centrifugal force. After the water in the pump is thrown, the central portion of the impeller forms a vacuum region. The liquid is continuously sucked in while continuously giving a certain amount of energy to the inhaled liquid to discharge the liquid. The centrifugal pump works continuously like this.

Centrifugal pumps are widely used. In addition to industrial applications, centrifugal pumps are also widely used in agricultural irrigation, municipal water supply, power station circulating water supply, and urban pollution treatment.
