Before opening the pump, the suction tube and pump must be filled with liquid. After the pump is turned on, the impeller rotates at a high speed and the liquid rotates along with the blades. Under the action of centrifugal force, the liquid will fly out of the impeller and the liquid will gradually become slower in the diffusion chamber of the pump housing, and the pressure gradually increases. Export, discharge pipe outflow. At this time, at the center of the vane, liquid is thrown around to form a vacuum low-pressure area free of air and liquid, and the liquid in the liquid pool flows into the pump through the suction pipe by the atmospheric pressure of the pool surface, Continuously sucked up from the liquid pool and continuously from the discharge pipe outflow.
