The operating principle of the centrifugal pump

Before starting the centrifugal pump, fill the pump with water. After starting, the rotating impeller drives the water in the pump to rotate at high speed. The water makes centrifugal movement, is thrown out and pressed into the outlet pipe. After the water is thrown out, the pressure near the impeller decreases and a low-pressure area is formed near the rotating shaft. The pressure of the centrifugal pump here is much lower than atmospheric pressure. Under the action of atmospheric pressure, the outside water rushes open the bottom valve and enters the pump from the water inlet pipe. The water rushed in is thrown out in the high-speed rotation with the impeller and pressed into the outlet pipe. Driven by the power machine, the impeller rotates continuously at high speed, and the water is continuously pumped from the low to the high.(centrifugal pump)
