                                             Multi-stage submersible pump unit composition.

Deep well pump 350 meters 450 meters 550 meters deep well pump

For deep wells: the outer diameter of the pump is 143mm, the head can reach 1500 meters, and the flow rate is 30 cubic meters/hour. Because the axial force is eliminated, the performance is stable, low noise and long life.

For mine use:  

pump outer diameter: 460mm, 570mm, flow rate of 100 cubic meters, lift of 800 meters, flow rate of 300 cubic meters, lift of 500 meters can be achieved.

This kind of pump does not produce axial force, the flow rate can be 50m3/h to 500m3/h, and the head can be 300 meters, 400 meters, 500 meters, 600 meters, 700 meters, 800 meters, 900 meters, 1000 meters, high efficiency 70%.

The flow rate can reach 2200 tons per hour, and the head can reach 1500m.

It is no longer a problem to have a flow rate of 500 tons and a head of 500 meters at the same time!

1. The multi-stage submersible pump unit consists of four parts: water pump, submersible motor (including cables), water pipe and control switch.

The submersible pump is a single-suction multi-stage vertical centrifugal pump: the submersible motor is a sealed water-filled wet type, oil-filled type, vertical three-phase asynchronous motor. The motor and the water pump are directly connected through a claw or single-cylindrical coupling; equipped with different Specifications of three-core cable; the starting equipment is an air switch of different capacity levels and an auto-coupling decompression starter, the water pipe is made of steel pipes of different diameters and is connected by flange, and the high-lift electric pump is controlled by a gate valve.

2. Each stage of the submersible pump is equipped with a rubber bearing in the diversion casing; the impeller is fixed on the pump shaft with a tapered sleeve; the diversion casing is integrated with threads or bolts.

3. The upper part of the high-lift submersible pump is equipped with a check valve to prevent damage to the unit caused by water sag during shutdown.

4. The upper part of the submersible motor shaft is equipped with a labyrinth sand preventer and two reversely assembled skeleton oil seals to prevent quicksand from entering the motor.

5. The submersible motor uses 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 regulate pressure changes caused by temperature; the motor windings are insulated with polyethylene and nylon-sheathed durable consumer product water electromagnetic wires. , the cable connection method is based on the QJ type cable joint process, take off the joint insulation and scrape off the paint layer, connect them separately, weld firmly, and wrap a layer of raw rubber around them. Then wrap 2 to 3 layers of waterproof adhesive tape, and wrap 2 to 3 layers of waterproof tape on the outside or a layer of rubber tape (bicycle inner tape) with water glue to prevent water seepage.

6. The motor is closed, using precision stop bolts, and the cable outlet is sealed with a rubber gasket.

7. There is a water injection hole on the upper end of the motor, a vent hole, and a water drain hole on the lower part.

8. The lower part of the motor is equipped with upper and lower thrust bearings. 

There are grooves on the thrust bearing for cooling. The stainless steel thrust plate grinds against it to follow the up and down        axial force of the water pump.
