Background

The drain pump relies on an impeller that rotates at high speed,

the liquid gains energy under inertial centrifugal force to increase pressure. Before the water pump works, the pump body and the water inlet pipe must be filled with water, so that the cavitation phenomenon is prevented. When the impeller rotates rapidly, the blades promote the water to rotate rapidly, the rotating water flies away from the impeller under the action of centrifugal force, and after the water in the pump is thrown out, a vacuum area is formed in the center of the impeller. The water from the water source is pressurized into the water inlet pipe through the pipe network under the action of atmospheric pressure (or water pressure). Thus, continuous water pumping can be realized after circulation is not completed, and the drainage pump can be used for draining liquid in the water accumulation tank or the large liquid storage tank.
