Does the oil of the oil air compressor refer to the bearing lubricating oil?

The oil of the oil air compressor does not specifically refer to the bearing lubricating oil, but refers to the lubricating oil used to lubricate and cool the internal parts of the air compressor, usually referred to as air compressor oil or air compressor special oil.

The main functions of oil air compressor include:

1. lubrication: Reduce the friction between the internal parts of the air compressor, reduce wear, and extend the service life of the equipment.

2. Cooling: When circulating inside the air compressor, it absorbs part of the heat and discharges the heat generated by friction out of the machine to cool down and prevent the air compressor from overheating.

3. Seal: Prevent gas leakage and improve the working efficiency of the air compressor.

4. Clean: Remove impurities, metal debris and other substances inside the air compressor to keep the equipment clean.

5. Rust prevention: Protect the metal parts inside the air compressor from corrosion.

The difference between the oil of the oil air compressor and the bearing lubricating oil:

1. different use scenarios:

   • oil for air compressor with oil: Specially used for the lubrication and cooling of air compressors, adapting to the environment of high temperature, high pressure and oxidized water.
   • bearing lubricating oil: Used for bearing lubrication of various mechanical equipment, mainly focusing on the friction, wear and life of the bearing.

2. Different performance requirements:

   • oil for air compressor with oil: It needs to have good oxidation resistance, wear resistance, corrosion resistance, and good adhesion and fluidity.
   • bearing lubricating oil: It is necessary to have suitable viscosity, anti-wear performance, extreme pressure resistance, etc. to ensure the normal operation of the bearing.

3. Additive composition is different:

   • oil for air compressor with oil may contain viscosity index improvers, pour point depressants, antioxidants, detergent dispersants and other additives to meet the special working environment and performance requirements of air compressors.
   • bearing lubricating oil: May contain different additives to meet the lubrication and cooling needs of the bearing.

Summary:

the oil of the oil air compressor is a kind of lubricating oil specially designed for the air compressor. It is not only used for the lubrication of the bearing, but also undertakes various functions such as cooling, sealing, cleaning and anti-rust. Therefore, it cannot be simply equated with bearing lubricating oil. When selecting and using, it should be carried out in strict accordance with the recommendations of the equipment manufacturer to ensure the normal operation of the air compressor and extend the service life.
