Leaks in the pump shaft seal of spinning oil agents directly affect operational safety and cleanliness and need to be addressed promptly.
Main causes:
1. Seal failure: Wear of the rotating/stationary rings, aging of O-rings (most common), caused by long-term operation, medium corrosion, or wear from impurities in the oil agent.
2. Shaft journal wear or scratches: Grooves on the shaft surface in contact with the seal due to wear or improper installation, leading to poor sealing.
3. Abnormal operating conditions: System pressure too high or fluctuating frequently, excessive pump shaft vibration, exceeding the design limits of the seal.
4. Improper installation: During seal installation, insufficient cleaning, reversed orientation, or incorrect compression adjustment.
