　　The long-axis pump is a kind of centrifugal pump. From the point of view of the centrifugal pump, it is improved on the performance of the submerged pump. The pump can be used to transport rainwater, scale water, sewage, corrosive industrial Waste water, sea water and other liquids. Widely used in water supply companies, sewage treatment plants, steel plants, mines and other industrial and mining enterprises, as well as municipal water supply and drainage, farmland irrigation, flood control and drainage and other projects.

　　The working principle of the long-axis deep well pump is a vane pump that lifts water from the well. The long-axis deep well pump is a kind of pump that is widely used in deep well pumps, and is generally used in motorized wells. The deep well pump is mainly composed of three parts: the upper part is the motor, the middle part is installed on the wellhead ground is the water delivery pipe and the lower end of the drive shaft is the working part of the deep well pump, which is submerged below the well water surface. Due to the depth of the well, a larger head is required.

　　Long shaft deep well pumps can be divided into segmented multistage vertical centrifugal pumps. According to the structural characteristics of the deep well pump, correct use and timely troubleshooting are crucial to the safe operation of the deep well pump and the extension of its service life.

　　Before the long shaft 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 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, a vacuum low-pressure area without air and liquid is formed at the center of the blade due to the liquid being thrown to the surroundings. 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 continues like this. It is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe.
