Submersible pump is a very widely used water treatment tool. The submersible pump is different from the ordinary pump. It works under water, and most of the pumps work on the ground. The working principle of the submersible pump: before the pump is pumped, the suction pipe and the pump must be filled with liquid. Open the pump, the impeller rotating speed, submersible pump with the liquid with the rotating blades, under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the submersible pump, the liquid is continuously pumped from the liquid pool was up and continuous outflow from the discharge pipe. The basic parameters of the submersible pump: including flow, head, pump speed, supporting power, rated current, efficiency, diameter and so on. The main purpose and submersible pump application: including the construction schedule, water, agricultural irrigation, industrial water cycle, urban and rural drinking water supply, and even disaster relief and so on

The working principle of the submersible pump

Before the pump is opened, the suction pipe and the pump must be filled with liquid. After the pump is opened, the impeller rotates at high speed. The liquid moves along with the blades. Under the action of centrifugal force, the impeller flies outward, and the liquid ejected slowly slows down in the diffuser of the pump housing, and the pressure gradually increases. Then it flows out from the pump outlet and the discharge pipe. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.

Two. Basic parameters of the submersible pump

It includes flow, lift, pump speed, matching power, rated current, efficiency, pipe diameter, and so on.

Three. Main use and application range of submersible pump

It includes construction arrangement, water and agricultural irrigation and drainage, industrial water circulation, urban and rural residents citing water supply, even emergency rescue and relief, and so on.
