B Sewage submersible pump
B/ Mine explosion-proof sewage and sand discharge submersible electric pump is an electric drainage and irrigation equipment that combines a pump and a motor. It has beautiful appearance, simple structure, good sealing performance and stable performance. , has a long life, is easy to install and use, and can operate continuously underwater for a long time. It is widely used in coal mine vertical shafts, inclined shafts and automatic drainage of loose coal mud at the bottom of the shaft. Built-in electric pump, water flows through the interlayer of the motor, effectively extending the service life of the electric pump. Externally installed electric pump, the impeller adopts a double-channel large overflow structure, stable operation, strong sewage discharge capacity, anti-winding, no clogging, and It has the characteristics of small size, light weight and easy to carry.
B/The working principle of the submersible pump: Before opening the pump, 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, and then flows out of the pump. Outlet, discharge pipe flows out. At this time, a vacuum low-pressure zone with neither air nor liquid is formed at the center of the blade because the liquid is 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. The liquid continues like this. It is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe.
