QJ submersible pump motor and pump integrated directly into the water to work water equipment , which applies to groundwater from deep pinch , can also be used in rivers, reservoirs , canals until water projects : mainly used for irrigation and the mountain plateau drinking water and also for the cities , factories , railways, mines, construction sites for drainage be used.
1, QJ deep well submersible pump consists of : water pumps, submersible motors ( including cable ) , pipes and control switches four major components. Submersible pump is single -suction multi- stage vertical centrifugal pumps : submersible motor is sealed water-filled wet , vertical three-phase cage induction motor, motor and pump through the claw coupling or single- cylinder direct health ; equipped with three different specifications core cable ; starting equipment of different capacity levels of air pressure switch and self-dual starters, mains of different diameter steel pipe , flange connection , highlight the theme of the program using the pump control valve .
2 , each stage submersible pump (www.greenco.cn) with a rubber shell deflector bearing ; impeller with cone sleeve fixed to the pump shaft ; diversion shell with screw or bolt into one .
3 Praise Submersible Pump top with check valve, causing the unit to avoid downtime vertical water damage .
4 , submersible motor shaft unit is equipped with a labyrinth of sand and two reverse assembled seal, to prevent the flow of sand into the motor .
5 , submersible motor with water lubricated bearings , the lower tone laminated with rubber , pressure springs, composed surge chamber , adjust the pressure changes due to temperature ; motor winding insulation using polyethylene , nylon sheath wire durables water , the cable connection mode by QJ type cable connector technology, scrape the paint off the joint insulation were connected, welding firm , with raw rubber around the floor. Then waterproof adhesive tape wrapped around 2 to 3 layers , the outside package 2 to 3 layers waterproof bandages or water wrapped in a layer of glue rubber band ( bicycle inner tube ) to prevent water seepage.
6 , the motor sealed using precision spigot bolt , cable outlet add cushion for sealing.
7 , the motor has an upper injection hole has a vent hole , the lower part has a drain hole .
8 , the motor up and down with the lower thrust bearing , thrust bearing with grooves for cooling , and it is a stainless steel grinding thrust plate , with the axial force of the pump up and down .
