Description

QJ submersible pump for wells is a water-lifting machine for the direct connection of the motor and the pump to submerged water. It is suitable for extracting ground water from deep wells, and can also be used for water-lifting projects such as rivers, reservoirs, and canals: mainly used for farmland irrigation and plateau mountain areas The water used by humans and animals can also be used for water supply and drainage in cities, factories, railways, mines, and construction sites.

Main Feature

1. The motor and pump are integrated into the water andoperate safely and reliably.2.There are no special requirements for well pipes and waterpipes (ie: steel pipe wells can be used; under pressure permit, steel pipes, hoses, plastic pipes, etc. can be used as water pipes)
2. It is easy to install, use and maintain. It occupies a smallarea and does not require the construction of a pump room.
3. The structure is simple, saving raw materials.
4. We can make cast iron and stainless steel two type ofmaterial as yourrequest.

Whether the use conditions of submersible pumps are appropriate and whether they are properly managed is directly related to their service life.

Structure Explanation

1. Submersible electric pump is composed of five parts: water pump, motor, water line, waterproof cable and control switch. Water pump belongs to single suction multistage vertical centrifugal pump.
2. Submersible motor adopts YQS type water-filled wet structure the chamber full of clear water, mainly for cooling the motor and the bearing lubrication. During operation, as the temperature changing may cause the water-filling volume to vary, a pressure regulator is equipped in the motor to allow the calibration.
3. For preventing the sand getting into the motor, a sand-preventing sealing mechanism consisting of a sand thrower and amechanical seals mounted on the upside motor, composing asand-preventing structure, the whole motor is well sealed by its sealing structure.
4. There are water injection hole and exhaust hole in the upper partof the motor and discharge hole in the lower part.
5. Thrust bearing and thrust collar are installed at the lower part ofmotor, mainly subjected to the axial force of the electric pump.
6. The winding of motor stator adopts water-proof electromagneticwire with good insulating and water-proof functions and rotoradopts squirrel-cage structure.
7. The stainless steel submersible pump is used for corrosivewater quality
