Compressor Oil Analysis: Performance Evaluation and Quality Control

What are Compressor Oils?

Compressor oils are lubricating fluids that are critical to keep industrial compressors running efficiently. Proper lubrication of compressors helps prevent friction, wear, heat generation and other problems in the system. Therefore, regular analysis of compressor oils and implementation of quality control methods are essential to maximize compressor performance and extend its life.

Compressor oils are polyalphaolefin-based oils produced by blending fully synthetic base oils and special additives, which ensure long life, high performance and trouble-free operation even under the harshest conditions and high temperatures.

Compressor oils are used in all types of screw and vane air compressors. The important issue for compressor oils is to be resistant to harsh climatic, environmental and high temperature conditions. They must have a service life of 8000 hours under normal operating conditions. They should have high oxidation resistance, low tendency to form soot and be easily separated from water.

Duties and Importance of Compressor Oils

  • Lubrication: Minimizes energy loss by reducing friction and wear between compressor components.
  • Cooling: Prevents overheating of components by dissipating the heat generated in compressors.
  • Corrosion Protection: Prevents the formation of rust and corrosion on metal surfaces.
  • Contaminant Control: It ensures efficient operation of the components by removing contaminants in the oil.


Quality Control Methods

  • Periodic Oil Analysis: Compressor oils should be analyzed regularly and changes in the operating process monitored. These analyses allow early detection of possible failures and the implementation of preventive maintenance strategies.
  • Filtration Systems: Filtration systems are used to prevent particulate contamination in the oil. Microfilters and magnetic filters remove metal particles and solid contaminants.
  • Oil Life Monitoring : Signs of oxidation and chemical degradation are closely monitored. Oil changes or additives are added if necessary.
  • Water and Pollution Control: Water separators and aeration systems can be used in the lubrication system to prevent water pollution.
  • Additive Analysis: The level of antioxidant and anti-rust additives in the oil is checked.
