Small submersible sewage pump is a kind of sewage treatment equipment with pump and motor connected design, submerged under liquid work, widely used in municipal engineering, industrial wastewater treatment and building drainage field. The equipment adopts vertical structure, with compact structure, low noise characteristics, can be directly installed in the sewage pool operation.
Submersible sewage pumps are submersible sewage pumps that are particularly suitable for transferring liquids containing hard solids, fibrous materials, and particularly dirty, sticky and slippery liquids. There are two types: AS and AV submersible sewage pumps.
QW submersible sewage pump is a kind of pressure pump with large flow channel anti-clogging hydraulic parts design, which greatly improves the dirt passing ability.
The biggest feature of deep well pump is to make the motor and pump into one, it is immersed in the groundwater well for pumping and conveying water, a kind of pump, which is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage and sewage treatment. As the motor is submerged in water at the same time, the structure requirements for the motor are more special than the general motor. The structure of the motor is divided into four types: dry type, semi-dry type, oil-filled type and wet type.
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 vane, and under the action of centrifugal force, it flies away from the impeller and shoots outward, and the liquid shot out in the diffusion chamber of the pump casing slows down gradually, and the pressure increases gradually, and then it flows out from the outlet of the pump and the discharge pipe. At this time, in the centre of the vane as a result of the liquid is thrown to the surrounding and the formation of neither air nor liquid vacuum low-pressure area, the liquid in the pool of liquid pool under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is so continuously from the pool of liquid is pumped up and continuously from the discharge pipe out.
