QJ type submersible pump motor and pump is directly into the water to work, it is suitable for deep groundwater, but also can be used for scooping from rivers, reservoirs and canals for water projects: mainly used for irrigation and plateau in the drinking water, but also for the city, factories, mines, railways, the site used for drainage.
Four major characteristics1. motor and water pump worked as a whole, deep into the water, safe and reliable.
2.the well pipe and pump water pipe without special requirements (i.e.: steel tube wells, tube wells, Doi ash can be used; in the permit, pressure pipe, hose, plastic pipe can be used for lifting pipe use
3.installation, use and maintenance is convenient and simple small area, does not need to build the pumping station.
4.the structure is simple, save raw materials.
Whether the condition is suitable, proper management and service life have a direct relationship.
UsageThe water pump motor and pump directly into the water to work, it is suitable for the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects: mainly used for irrigation and plateau in the drinking water, but also for the city, factories, mines, railways, water supply and drainage engineering to use. Main features: 1 motor, water pump, submerged operation, safe and reliable. The 2 tube wells and pumping pipe without special requirements (i.e.: steel tube wells, tube wells, Doi ash can be used in pressure; permit, pipe, hose, plastic pipe can be used for lifting pipe use). 3 installation, use and maintenance is simple and convenient, small occupied area, without the construction of pumping stations. 4 simple structure, saving raw materials. Whether the condition of the use of the submersible pump is suitable, proper management and service life have a direct relationship.
Rated frequency :50 Hz, rated voltage:380+5% volts three-phase AC power supply.
The water inlet of the water pump in the water level must be below 1 meters, but the diving depth shall not exceed the static water level of 70 meters below the lower end of the motor, from the bottom of at least 1 meters above the water depth.
Water temperature is generally not higher than 20OC.
Water quality requirements:
Sand content in water is not more than 0.01% (weight ratio);
PH value: 6.5~8.5
hlorine ion content:no more than 400 mg / L
straight well,inlet is smooth, no three tube stagger.
QJ type submersible electric pump unit consists of four parts: water pump, submersible motor (including cable), water delivery pipe and control switch.
Submersible pump for multi-stage single suction vertical centrifugal pump, submersible motor for confined water filling, wet vertical three-phase squirrel cage asynchronous motor, motor and pump through the claw type or single cylinder type direct coupling health; equipped with three core cables of different specifications for different levels of capacity; starting equipment air switch and self starter, water steel pipe made of different diameter, the flange connection, high pump control valve using the program.
A rubber bearing is arranged in the casing of the submersible pump, and the impeller is fixed on the pump shaft with a conical sleeve; the guide shell is connected with a screw thread or a screw bolt.
High lift submersible pump with check valve on the upper part to avoid downtime caused by the destruction of the unit.
The submersible motor shaft is arranged on the upper part of the labyrinth seal sand control device and two reverse assembly, to prevent the flow of sand into the motor.
submersible motor with water lubricated bearings, the lower part is provided with a rubber film, adjustable pressure regulating spring, composed of surge chamber, adjustment because of the change in pressure caused by temperature; motor winding adopts polyethylene insulated nylon sheathed consumer durable goods hydro magnetic line, cable connection joints according to QJ type of cable joint insulation, to scrape off the paint layer, are connected, welding firm, with around a layer of rubber. Use waterproof tape wrapped around the 2~3 layer, 2~3 layer is coated on the outer surface of waterproof tape or glue water wrapped in a layer of rubber belt (bicycle belt) to prevent water seepage.
The electric motor is closed, and the cable outlet and the rubber pad are sealed by the precision stop bolt.
The upper end of the motor has a water injection hole, a discharge hole, a lower hole.
The lower part of the motor is provided with an upper and a lower thrust bearing, a groove is used for cooling, and a stainless steel pushing plate is applied in the grinding, and the upper and the lower axial forces of the pump are arranged.
The motor must be filled with water before use, water gas tighten bolts, or are not allowed to use (Note: some QJ deep well pump model is the need to refuel, you must call the factory water before use, or have good oil). 2, the land must not be more than one second to run. 3, do not use electric pump or lying in. 4, the motor must be completely submerged, but the depth should not be more than 70 meters depth. 5, wire and cable joints in accordance with the provisions of the operation. 6, the order of high lift submersible pump please refer to the "high lift submersible pump type spectrum" and "high lift submersible electric pump use manual". 7, high lift submersible pump maximum head does not exceed 3000 meters.
