Centrifugal pump refers to a pump that transports liquid by the centrifugal force generated by the rotation of the impeller. When the centrifugal pump is working, the impeller is driven by the motor to rotate at a high speed, forcing the liquid between the blades to rotate at a nearly constant angular velocity. , so that the liquid moves radially from the center of the impeller to the outer edge. The liquid obtains energy during the movement in the impeller, and leaves the outer edge of the impeller at a high speed into the volute pump casing. In the volute, due to the gradual expansion of the flow channel, the Slow down, convert part of the kinetic energy into potential energy, and finally flow into the outlet pipe along the tangential direction. The high-speed rotation of the electronic internal rotor will generate a large amount of heat energy.
