Principle of centrifugal water pump
Before starting, the pump should be filled with water. After starting, the rotating impeller drives the water in the pump to rotate at a high speed, and the water is thrown out and pressed into the outlet pipe. As the water is thrown out, the pressure near the impeller decreases, forming a low pressure area near the rotating shaft. The pressure here is much lower than in the atmosphere, and the water outside, under the action of atmospheric pressure, opens the bottom valve and enters the pump through the intake pipe. The water rushed in with the impeller high-speed rotation and was thrown out, and pressed into the outlet pipe. The impeller is constantly rotating at high speed driven by the power machine, and the water is constantly pumped from the lower to the higher.
