What oil is added to the air compressor

What oil is added to the air compressor needs to be determined according to the type of air compressor. Small piston air compressor generally use ordinary mechanical oil can, viscosity is not too high on the line. If it is a screw air compressor or sliding vane air compressor, it is necessary to use special lubricating oil. Air compressor oil mainly plays the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Its type is roughly divided into three types: synthetic oil, semi-synthetic, mineral oil;

air compressor with what oil? Air compressor oil function analysis:

1) Lubrication: It is to lubricate the screw host to form a lubricating oil film between the rotors;

2) Sealing function: mainly to fill the leakage gap between the rotor and the housing;

3) Cooling effect: mainly means that it can effectively control the temperature rise caused by the heat release of the compressor;

4) Noise reduction effect: The injected oil is a viscous fluid, which has absorption and damping effects on sound energy and sound waves. Generally, after fuel injection, the noise can be reduced by 10-20 decibels, that is: dB(A) because the air compressor oil is divided into: Mineral oil and synthetic oil. Because of its inherent composition is different, under normal circumstances, the service life of mineral oil is about half shorter than that of synthetic oil.

Mineral oil: under the condition of good unit temperature and working conditions, the service life can reach about 3000-4000 hours. If the air compressor is operating under the condition of more dust and pollutants, it is recommended to replace it at about 2500-3000 hours.

Synthetic oil: Under the condition of good unit temperature and working conditions, the service life can reach about 6000-8000 hours. If the operating conditions are in a dusty and multi-fiber environment, it must be replaced after 6000 hours.
