WORK PRINCIPLE
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. After the water is thrown out, the pressure near the impeller is reduced, and a low pressure area is formed near the rotating shaft. The pressure here is much lower than the atmospheric pressure, and the water outside is under the action of atmospheric pressure, flushing the bottom valve and entering the pump from the water inlet pipe. The rushing water is thrown out again with the high-speed rotation of the impeller, and is pressed into the water outlet pipe. The impeller is continuously rotated at high speed by the power machine, and the water is continuously pumped from the low to the high.
