When the plastic pump filled with water, the centrifugal force produced by the rotation of the impeller, water pump under the action of centrifugal force of the impeller, jilt to peripheral flow into the pump shell, so the center of impeller reduced pressure, the pressure is lower than the water tube, under the action of water on the pressure difference by suction tank into the impeller. This pump can continuously absorbing water and constantly water supply. In addition to the role of the impeller, the function of spiral pump casing is also very important. Obtained energy liquid flows out from the impeller has great function, when the liquid in the spiral pump shell were collected, and behind the spread of the tube in the kinetic energy into pressure energy. Compared with other types pumps, it has a simple structure, wear resistance, smooth operation, low noise, uniform water flow, convenient adjustment and high efficiency, etc.
