Rotary Screw Compressor: Analyzing Causes and Solutions for Oil Leakage

I. Causes of Oil Leakage in Rotary Screw Compressor

1. Aging Seals: The seals within the rotary screw compressor, including gaskets and sealing rings, undergo wear and tear over prolonged operation periods. This deterioration leads to reduced sealing efficiency, ultimately causing oil leaks.

2. Blocked Oil Lines: Contamination or blockages in the oil system can hinder the proper circulation of oil during compressor operation. This results in increased oil pressure, contributing to oil leakage.

3. Excessive Oil Level: An overly filled oil tank can cause oil to overflow within the compressor, leading to leaks. This commonly occurs due to incorrect filling procedures by operators or faulty oil level indicators.

4. Improper Installation: Failure to install components correctly during the compressor setup, such as uneven sealing surfaces or unevenly tightened bolts, can significantly contribute to oil leakage.

II. Effective Solutions to Address Oil Leakage 

1. Regular Seal Inspection: To maintain the integrity of the compressor’s seals, regularly inspect gaskets, sealing rings, and other sealing components. Promptly replace worn-out or damaged seals to ensure optimal sealing performance.

2. Oil System Cleaning: Schedule regular cleaning of the oil system to prevent blockages. Use a suitable cleaning agent to remove impurities and dirt, ensuring smooth oil flow throughout the system.

3. Oil Level Management: Adhere strictly to the recommended oil filling procedures to prevent excessive oil levels. Regularly check the functionality of oil level indicators and take corrective measures immediately if faults are detected.

4. Enhance Installation Quality Control: During compressor installation, follow established procedures meticulously. Pay special attention to critical components, ensuring that sealing surfaces are flat and bolts are tightened to the appropriate torque specifications.
