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.

Deep well submersible water pump structure&model meaning
1. Submersible electric pump is composed of five parts: water pump, submersible motor, water line, waterproof cable and control switch. Water pump belongs to single suction multistage vertical centrifugal pump.
2. Submersible motor adopts water-filled wet structure, internal chamber was filled with water for cooling the motor and lubricating the bearing. In the operation, due to the changes of temperature, the pressure of the filled water in the internal chamber also changes, it can be automatically regulated by pressure-regulating unit in the lower part of motor.
3. For preventing the sand getting into the motor, the sand-preventing unit including sand and skeleton oil-sealed was installed in the upper part of motor, the whole motor was sealed tightly.
4. There are water injection hole and exhaust hole in the upper part of the motor and discharge hole in the lower part.
5. There are thrust bearing and thrust collar, mainly for sustaining remnant axial force of pump and the empty weight of motor's rotor.
