Five, QJP series stainless steel deep well submersible pump features

1, motor, pump integration, diving into the water operation, safe and reliable.

2, no special requirements for well pipes and lifting pipes (that is, steel pipe Wells, ash pipe Wells, earth Wells, etc., can be used; Under the pressure permit, steel pipe, hose, plastic pipe, etc., can be used as a lifting pipe

3, easy to install, use, maintenance, small footprint, no need to build pump room.

4, simple structure, save raw materials, proper management and service life has a direct relationship.

Six, QJP series stainless steel deep well submersible pump structure description

1. QJP stainless steel deep well pump consists of four parts: water pump, submersible motor (including cable), water transmission pipe and control switch. Submersible pump is a single suction multi-stage vertical centrifugal pump: submersible motor is a closed water-filled wet, vertical three-phase cage asynchronous motor, the motor and the pump through the claw or single cylinder coupling directly; Equipped with three core cables of different specifications; The starting equipment is made of different capacity levels of air switch and self-coupling pressure starter, the water transmission pipe is made of different diameters of steel pipe, using flange connection, the high Yang program electric pump is controlled by gate valve.

2, each stage of the submersible pump guide shell is equipped with a rubber bearing; The impeller is fixed on the pump shaft with a conical sleeve; The guide shell is threaded or bolted into one body.

3, the upper part of the submersible pump is equipped with a check valve to avoid the damage of the unit caused by the shutdown water sag.

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

5, the submersible motor uses water-lubricated bearings, the lower part is equipped with rubber pressure regulator film, pressure regulator spring, composed of pressure regulator chamber, adjust the pressure change caused by temperature; The motor winding adopts polyvinyl insulation, nylon sheathed durable consumer goods water electromagnetic wire, cable connection method according to QJ cable joint process, the joint insulation to remove the scraped paint layer, respectively connected, welded firmly, with raw rubber around a layer. Then wrap 2 to 3 layers of waterproof adhesive tape, and put 2 to 3 layers of waterproof tape on the outer bread or wrap a layer of rubber belt (bicycle belt) with water adhesive to prevent water seepage.

6, the motor is sealed, the use of precision stop bolts, the cable outlet with rubber pads to seal.

7, the upper end of the motor has a water injection hole, there is a release hole, the lower part has a water release hole.

8, the lower part of the motor is equipped with upper and lower thrust bearings, thrust bearings have grooves for cooling, and it is worn on the stainless steel thrust plate, with the upper and lower axial force of the pump.
