The Working Principle Of The Submersible Pump

Before opening the pump, the suction pipe and the pump must be filled with liquid. After opening the pump, the impeller rotates at high speed, the liquid in it rotates with the blades, under the action of centrifugal force, it flies out of the impeller and shoots outward, the injected liquid gradually slows down in the pump casing diffusion chamber, the pressure gradually increases, and then flows out of the pump outlet and discharge pipe. At this time, at the center of the blade, due to the liquid being thrown around, a vacuum low pressure area with neither air nor liquid is formed, and the liquid in the liquid pool flows into the pump through the suction pipe under the action of atmospheric pressure on the pool surface, and the liquid is continuously sucked up from the liquid pool and continuously flows out of the discharge pipe.
