Does oil in an oil-filter refer to bearing lubricating oil?

The oil in an oiled air compressor does not specifically refer to bearing lubricating oil, but refers to lubricating oil used to lubricate and cool various components of the air compressor, which is usually called air compressor oil or special oil for air compressors.

The main functions of oil in oil-containing air compressors include:

  1. Luction: reduces friction between various components inside the air compressor, reduces wear, and extends the service life of the equipment.
  2. Cooling: When the air compressor is circulating internally, it absorbs part of the heat and discharges the heat generated by friction out of the machine, which can cool down and cool down, and prevent the air compressor from overheating.
  3. Sealing: Prevent gas leakage and improve the working efficiency of the air compressor.
  4. Cleaning: Remove impurities, metal debris and other substances inside the air compressor to keep the equipment clean.
  5. Rust Anti-rust: Protect metal parts inside the air compressor from corrosion.

The difference between oil in oil-containing air compressors and bearing lubricating oil:

  1. Different use scenarios:
    • Oil of oil in oil-containing air compressors: It is specially used for lubrication and cooling of air compressors, adapting to high temperature, high pressure and environments with oxidized water.
    • Bearing lubricating oil: used for bearing lubrication of various mechanical equipment, mainly focusing on the friction, wear and life of bearings.
  2. The performance requirements are different:
    • Oil with oil air compressors: It is necessary to have good oxidation resistance, wear resistance, corrosion resistance, as well as good adhesion and fluidity.
    • Bearing lubricating oil: It is necessary to have appropriate viscosity, wear resistance, extreme pressure resistance, etc. to ensure the normal operation of the bearing.
  3. Added additives have different ingredients:
    • Oil with oil air compressors: It may contain a variety of additives such as viscosity index improvers, pour point dropping agents, antioxidants, detergent dispersants, etc. to meet the special working environment and performance requirements of the air compressor.
    • Bearing lubricating oil: OKCan contain different additives to meet the lubrication and cooling requirements of bearings.

Summary:

The oil in an oil-containing air compressor is a lubricating oil specially designed for air compressors. It is not only used for bearing lubrication, but also undertakes various functions such as cooling, sealing, cleaning and rust prevention. Therefore, it cannot be simply equivalent to bearing lubricating oil. When selecting and using it, it should be strictly followed by the equipment manufacturer’s recommendations to ensure the normal operation of the air compressor and extend the service life.
