"Who operates the mine submersible pump? Let's take a closer look at the key components and their functions.
1. **Cable Connector Sealing**
To prevent oil leakage from the cable leads, both the outer and inner connections are sealed. The cable leads are sealed on the outside of the housing, while the internal connection is sealed using epoxy glue. The cable and power connector are also firmly connected and tightly sealed to ensure good insulation and improve the overall reliability of the pump during operation.
2. **Bearing Design for Mechanical Seal Reliability**
To ensure the reliability of the motor’s oil-filled mechanical seal, it’s crucial that the motor rotor does not move axially. Therefore, two radial thrust bearings of different sizes are installed at the bottom of the motor. These bearings are designed to handle the axial forces generated during pump operation, both upward and downward. The bearings are fixed with nuts to prevent any movement of the shaft, ensuring that the static and dynamic mechanical seals remain intact during operation. This prevents oil leakage and protects the motor from external well water.
3. **Packing Structure and Oil Protection Signal Device**
To prevent well water from entering the motor, the system maintains a hydraulic pressure inside the motor that is higher than the external water pressure. A packing device is installed at the lower part of the motor, consisting of an oil bag, oil bag jacket, oil gland, and spring. After the motor is filled with insulating oil, the spring applies pressure, keeping the oil bag fully filled. This creates internal pressure that helps maintain the integrity of the mechanical seal. When functioning properly, only a small amount of insulating oil may slowly leak through the seal, but well water cannot penetrate into the motor.
