　　Screw air compressor oil quotation: What type of oil is needed for the air compressor

　　Lubrication principle of air compressor oil

　　The apparent phenomena caused by friction include high temperature, high pressure, noise, wear, etc. The most harmful one is wear, which includes adhesive wear, abrasive wear, corrosive wear, surface fatigue wear, etc. It directly affects the normal operation and even failure of mechanical equipment.

　　The function of air compressor oil is to form a protective film between two friction pairs, avoiding direct contact between metals, thus buffering the frictional force, providing lubrication, reducing wear, and protecting the normal operation of the machinery. This protective film can be a physical adsorption film, a chemical adsorption film, or an oxide film, and the thickness and strength of the film directly affect the lubrication effect.

　　The lubrication function of ordinary air compressor oil is mainly to form a layer of oil film between the friction surfaces for protection. The lubrication theory of air compressor oil relies on the adsorption film formed by additives on the friction surfaces for protection. The base oil itself only serves as an additive carrier and a sealing function between the friction surfaces, and the lubrication function of the oil film has been relegated to a secondary position

　　Air compressor oil is mainly used for lubricating the moving parts of compressor cylinders and exhaust valves, and plays a role in rust prevention, corrosion prevention, sealing, and cooling.

　　Performance of air compressor oil:

　　Due to the high pressure, high temperature, and presence of condensed water in the air compressor, the air compressor oil should have excellent high-temperature oxidation stability, low tendency to accumulate carbon, suitable viscosity and viscosity temperature performance, as well as good oil-water separation, rust and corrosion resistance. The base oils used for air compressor oil mainly include five types: synthetic hydrocarbons (poly - α - olefins), organic esters (diesters), polyalkylene glycol, fluorosilicone oil, and phosphate esters. Compared with mineral oil types, it has the advantages of good high-temperature stability, less carbon deposition at high temperatures, wide operating temperature, low pour point, low volatility, and long service life.
