QYOil filled submersible electric pumpproduct overview

QY typeOil filled submersible electric pumpIt consists of three parts: water pump, seal, and electric motor. The water pump is located at the upper part of the electric pump and is a centrifugal or axial flow structure. The electric motor is located at the lower part of the electric pump and is an oil filled three-phase asynchronous motor. The internal mechanical seal box is used to seal between the water pump and the motor, and an "o" - shaped oil rubber seal ring is used for static sealing at each fixed sealing point.

QYOil filled submersible electric pumpConditions of Use

Can work continuously and normally under the following usage conditions:
1. The working medium is non corrosive clean water, with a sand content of no more than 0.10% by volume and a particle size of no more than 0.20mm
2. The temperature of the medium should not exceed 40 ℃, and the pH value of the medium should be between 6.5-8.5
3Submersible pumpIt should be used within the range of use near the rated head And it should be fully immersed in water for use, with a diving depth not exceeding 3m and a maximum depth not exceeding 5m
4Submersible pumpStay at least 0.5m above the bottom of the water, but do not sink into the mud Otherwise, it may cause an explosion
5. The power frequency is three-phase 50Hz, the voltage is 380V, and the voltage fluctuation range is 0.9-1.1 times the rated value

QYOil filled submersible electric pumpPrecautions for use

1.Submersible pumpBefore use, carefully read the user manual, confirm that it meets the usage conditions, and strictly follow the precautions and requirements for unit installation, start-up, operation, and shutdown.

2. Before using the submersible motor, the chamber must be filled with clean water, otherwise it will cause the motor stator coil, thrust bearing, and guide bearing to heat up and burn out. When pouring water, both the water injection bolt and the air release bolt must be unscrewed at the same time to ensure smooth pouring of water and easy removal of air from the chamber.

3. The ground test run of the motor shall not exceed one second, and before the test run (the motor chamber has been filled with clean water), a sufficient amount of water should be poured into the oil seal of the motor shaft extension, otherwise it will cause the oil seal (or mechanical seal) to burn out.

4. If the motor andSubmersible pumpInstalled together, during the trial run, the check valve should be removed first, and then a sufficient amount of clean water (or laundry detergent water) should be slowly poured from the outlet of the water pump. At the same time, the pump shaft should be rotated to pre lubricate the rubber bearings of the water pump, otherwise the bearings will be burned out. Electric pumps should be used upright and should not be operated lying down.

5. High liftSubmersible pumpWhen the unit is heavy, two steel wire ropes must be added for load-bearing protection to prevent the unit from falling into the well. (It is recommended that all pumps used underground should be equipped with load-bearing protection)

6. Submersible pumpWhen not in use for a long time, it should be placed upright to prevent bending and deformation of the motor rotor and water pump rotor. Electric pumps should not be stored outdoors for a long time and should be stored in a warehouse, otherwise it will cause cable aging, insulation degradation and failure of motor winding coils, and rusting of components.Submersible pumpAfter long-term storage, it should be inspected and debugged before use.

7. After the submersible motor is taken out of the well in winter, the drain bolt and vent bolt should be tightened in a timely manner to drain the water stored in the motor cavity, otherwise it will cause the motor components to freeze and crack. When going down the well again, it is necessary to refill it with clean water. After the electric pump is lowered into the well, the insulation resistance to ground should be measured first with a 500 volt megohmmeter, which should not be lower than 5 megohms before conducting a water test. Otherwise, the conductive motor will be burned out.
