Submersible borehole pump for 10 inch manufacturers tell you that the submersible electric pump unit consists of four parts: water pump, submersible motor (including cable), water pipe and control switch. The submersible pump is a single-suction multi-stage vertical centrifugal pump; the submersible motor is a closed water-filled wet, vertical three-phase squirrel cage asynchronous motor, and the motor and the water pump are directly connected by a claw or single-key barrel coupling; equipped with different specifications. Three-core cable; the starting equipment is air switch of different capacity grades and auto-decompression pneumatic actuator, the water pipe is made of steel pipe with different diameters, connected by flange, and the high-lift electric pump is controlled by gate valve.

The manufacturer of Submersible borehole pump for 10 inch tells you that the upper part of the submersible motor shaft is equipped with a labyrinth sand control device and two skeleton oil seals assembled in the reverse direction to prevent quicksand from entering the motor. The submersible motor 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 manufacturer of Submersible borehole pump for 10 inch tells you that the motor winding is insulated by polyethylene and nylon Set of water-resistant electromagnetic wires, the cable connection method is based on the cable joint process, the joint insulation is removed and the paint layer is scraped off, respectively connected, welded firmly, and wrapped with a layer of raw rubber. Then wrap 2-3 layers of waterproof adhesive tape, and wrap 2-3 layers of waterproof tape on the outside or wrap a layer of rubber (bicycle lining) with water glue to prevent water seepage.
A rubber bearing is installed in each stage of the guide casing of the submersible pump; the impeller is fixed on the pump shaft with a conical sleeve; the guide casing is connected by threads or bolts. The upper part of the high-lift submersible pump is equipped with a check valve to avoid the damage of the unit caused by water hammer during shutdown. The motor is airtight, using precision stop bolts, and the cable outlet is sealed with a rubber gasket. The manufacturer of Submersible borehole pump for 10 inch tells you that there is a water injection hole at the top of the motor, a vent hole, and a drain hole at the bottom. The lower part of the motor is equipped with upper and lower thrust bearings, and there are grooves on the thrust bearings for cooling.
