Summary of submersible pumps for QJ wells
QJ-type submersible pump is a motor and pump directly into the water work of the water lifting equipment, it is suitable for extracting groundwater from the deep wells can also be used for rivers, reservoirs, canals and other water lifting projects: mainly for farmland irrigation and plateau mountain Human and animal water, but also for cities, factories, railways, mines, site for water use.
Key Features of Submersible Pump with QJ Type
1. Motor, water pump body, submerged into the water to run, safe and reliable.
2. There is no special requirement for the well pipe and the water pipe (ie, the steel pipe well, the ash pipe well, the soil well and so on can be used; under the pressure permission, the steel pipe, the hose, the plastic pipe and so on may serve as the water pipe).
3. Installation, use, easy maintenance Simple, small footprint, no need to build pump room.
4. Simple structure, saving raw materials. Submarine pump use of the conditions are appropriate, proper management and the life of a direct relationship.
QJ well submersible pump structure description
1.QJ submersible pump unit consists of: water pump, submersible motor (including cable), water pipes and control switch composed of four parts. Submersible pump for the single-suction multi-stage vertical centrifugal pump: submersible motor for the closed water-filled wet, vertical three-phase squirrel cage motor, motor and pump through the claw or in the key cylinder coupling directly equipped with different Specifications of the three-core cable: starting equipment for different capacity levels of air switch and auto-decompression starter, the water pipe for the different diameter of the steel pipe made of flange connection, high-lift pump with gate valve control.
2. Submersible pump Each stage of the baffle is fitted with a rubber bearing; the impeller is fixed to the pump shaft with a conical sleeve: the deflector is joined by a twist or bolt.
3. High-lift submersible pump with a check valve on the upper part, to avoid downtime caused by water hammer damage.
4. Submarine motor shaft with a labyrinth sandstand and two reverse assembly of the skeleton oil seal, to prevent the flow of sand into the motor.
5. Submersible motor with water lubricated bearings, the lower part of the rubber pressure regulating film, pressure regulating spring, composed of surge chamber, adjust the pressure caused by temperature changes; motor winding with polyethylene insulation, nylon sheath water-resistant magnet wire, cable connection Way by QJ-type cable connector technology, the connector insulation off scraping paint layer, were connected, welding firmly, with raw rubber around - layer. And then wrapped with water-resistant adhesive tape 2 to 3 layers, 2 to 3 layers outside the waterproof tape or glue with a glue layer of rubber tape (bike tire> to prevent water seepage.
6. The motor is sealed, the use of precision stop screw, cable outlet plus plastic school to seal.
7. There is a water injection hole on the top of the motor, there is a vent hole, Bu Department to make a hole.
8. The lower part of the motor is equipped with a bi-thrust bearing, the thrust bearing has a groove with dry cooling, and it is grinding stainless steel thrust plate, bearing the pump on the factory axial force.
♣ Deep Well Pump Advantages
♥ Easy installation
♥ Low noise, high temperature resistence, long service life.
♥ Fully operating in water avoiding entering air.
♥ Replacing the emergency pump quickly when the pump breaks down in harsh environment such as high temperature
water tank or pool,or somewhere that are inconvenient for man to maintain.
♥ Portable design with its small size and light weight. so you neednt install bay bolt.
1.100% copper rewindable wire
3.Fast delivery time
4.Dry run pretection
♣ The Choice of Submersible Motor Pump
The followig content should be understood in order to choose and operate submersible motor pump correctly:
1 Understanding all clauses mentioned in operation conditions
2 Pay attention to the diameter and the depth of well
3 Pay attention to the static water level and the flowing water level of well
4 Pay attention to the water surging capacity of the well
The capacity,head,and the diameter of full set should be shosen according to the water surging capacity,the depth and the diameter of well.The water surging capacity of well should meet the requirement of the capacity of submersible motor pump,so that the submersible motor pump can be under the water totally when it works.
