Working Principle Of Submersible Pump

Before opening the pump, the suction tube and the pump must be filled with liquids; open the pump, the impeller high-speed rotation, in which the liquid with the blade rotating, in the centrifugal force, flying out of the impeller, the injection of liquid in the pump shell diffusion indoor speed gradually slowly, the pressure gradually increased, and then from the pump outlet, drain pipe outflow.

At this time, in the blade center because the liquid is dumped around the formation of no air and no liquid vacuum zone, liquid in the pool surface atmospheric pressure, through the suction tube into the pump, liquid is so continuously from the liquid pool suction up and continuously flowing from the exhaust pipes.
