A hot water deep well pump consists of a water pump, a submersible motor (including cables), a water pipe and a control switch. Mostly composed. The submersible pump is a single-suction multi-stage vertical centrifugal pump. The submersible motor is a sealed water-filled wet type, vertical three-phase cage asynchronous motor. The motor and water pump are directly equipped with three-core cables of different specifications through claw or single-cylindrical couplings. The starting equipment is air switches of different capacity levels and auto-coupling decompression starters. The water pipes are made of steel pipes of different diameters and are connected by flanges. The high-lift electric pump is controlled by a gate valve.


Each stage of the hot water deep well pump is equipped with a rubber bearing impeller fixed on the pump shaft with a tapered sleeve in the diversion casing. The diversion casing is integrated with threads or bolts.


A check valve is installed on the upper part of the high-lift submersible pump to avoid damage to the unit caused by water sag during shutdown.


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.


'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 caused by temperature
br/> The pressure change motor windings are made of polyethylene insulated and nylon sheathed durable consumer goods electromagnetic wires. The cable connection method is according to the
type cable joint process. Take off the insulation of the joints and scrape off the paint layer, connect them separately, and weld them firmly. Wrap a layer of raw rubber. Then wrap it with a
~
layer of waterproof adhesive tape, and cover the outside with a
~
layer of waterproof tape or glue it with water glue and wrap it with a layer of rubber tape (bicycle inner tape) to prevent leakage water.


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


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


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. With the up and down axial force of the water pump, .
