Working Principle Of Outer Diameter Oil-filled Deep Well Pump

Before the oil-filled deep well pump is turned on, the suction pipe and the pump must be filled with liquid. After the pump is turned on, the impeller rotates at high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and is ejected outward. The ejected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases. Outlet, the discharge pipe flows out. At this time, a vacuum low-pressure area with neither air nor liquid is formed at the center of the blade due to the liquid being thrown around. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface, and the liquid is thus continuous. It is continuously sucked up from the liquid pool and continuously flows out of the discharge pipe.
