                                     Structural Description of Geothermal Submersible Pump For Deep Well


     Deep well submersible pump, geothermal submersible pump is a water-lifting tool that is directly connected to a motor and a water pump and submerges into water to work. It is suitable for extracting groundwater from deep wells, and can also be used for water-lifting projects such as rivers, reservoirs, and canals: geothermal submersible pumps are mainly used for farmland irrigation and water for humans and animals in plateau and mountainous areas, it can also be used for water supply and drainage in cities, factories, railways, mines, and construction sites.

    Structure description of geothermal submersible pump for deep well

The deep well submersible pump unit consists of four parts :

  • Water pump

  • Submersible motor (including cables)

  • Water pipe 

  • Control switch

  1. The submersible pump is a single-suction multi-stage vertical centrifugal pump: the submersible motor is a closed water

    filled wet type, vertical three-phase squirrel-cage asynchronous motor, and the motor and the water pump are directly connected through claw-type or middle-key barrel couplings; equipped with different Standard three-core cable: the starting equipment is an air switch of different capacity levels and an auto-coupling decompression starter, the water delivery pipe is made of steel pipes of different diameters, connected by flanges, and the high-lift electric pump is controlled by a gate valve.

2. A rubber bearing is installed in each diversion shell of the deep well geothermal submersible pump; the impeller is fixed on the        pump shaft with a tapered sleeve; the diversion shell is integrated with thread or bolts.

3. The upper part of the QJ deep well submersible pump is equipped with a check valve to avoid damage to the unit caused by            water hammer during shutdown.

4. The upper part of the submersible motor shaft of the deep well submersible pump is equipped with a labyrinth sand control            device and two skeleton oil seals assembled in reverse to prevent quicksand from entering the motor.

5. The submersible motor of the deep well submersible pump adopts water-lubricated bearings, and the lower part is equipped          with a rubber pressure-regulating film and a pressure-regulating spring to form a pressure-regulating chamber to adjust the            pressure change caused by temperature; the motor winding is insulated with polyethylene, and the nylon sheath is water-                resistant electromagnetic wire , The cable connection method is according to the QJ type cable joint process, the insulation of          the joint is removed and the paint layer is scraped off, connected separately, the welding is firm, and the layer is wound with raw      rubber. Then wrap 2-3 layers with waterproof adhesive tape, and wrap 2-3 layers of waterproof tape on the outside or wrap a          layer of rubber tape with water glue (bicycle inner tire> to prevent water seepage.

6. The motor of the deep well submersible pump is airtight, and the precision seam screw is used, and the cable outlet is sealed          with glue.

7. There is a water injection hole on the upper end of the motor of the deep well submersible pump, and there is a vent hole on          the  bottom.

8. The lower part of the motor of the deep well submersible pump is equipped with an upper-thrust bearing.
