There are several types of diving cooler pumps, and the wires in the motor are oil-immersed, water-immersed, and dry.

You must read the manual before using it, and you can’t make a mistake. If you don’t use it for a long time, you must turn the impeller before using it, otherwise it will burn because it will be stuck for a long time. Before starting the pump, the suction pipe and the pump must be filled with liquid. After the pump is turned on, the impeller rotates at a high speed, and the liquid in it rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots out. The speed of the injected 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, at the center of the diving cooler pump blade, the liquid is thrown to the surroundings to form a vacuum low-pressure area without air or liquid. 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. Just like this, it is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe.
