Interpretation of the main performance of air compressor oil

Air compressor oil is mainly used for the lubrication of the occluding positions of various mechanical parts, such as compressor cylinders, piston rings, bearings, speed-increasing gears, crank connecting rods and crankcase lubrication systems.

Proper viscosity can make the air compressor have good lubrication, cooling and sealing functions under the working temperature and pressure, and ensure the normal operation of the air compressor.

Since the exhaust temperature of an air compressor is usually between 120°C and 200°C, and may reach 300°C, the compressor oil is easily oxidized and deteriorated at high temperatures.

Therefore, air compressor oil must have the following main properties:

1. Good anti-emulsification, anti-corrosion and anti-foaming properties

Air compressor oil is easily mixed with condensed water and air, which can emulsify and deteriorate the oil, increase the corrosion and wear of mechanical parts, and oxidize the oil. Therefore, good anti-emulsification, anti-corrosion and oxidation resistance are essential for air compressor oil.

2. Good oxidation stability

Since the discharge temperature of the compressor is usually between 120°C and 200°C, and may reach 300°C, the compressor oil is easily oxidized at high temperatures and deteriorated to form sludge.

3. The tendency to deposit carbon is good

If carbon deposits accumulate in the exhaust system, the exhaust valve will not be closed tightly, and the cooling effect will be poor, which will increase the exhaust temperature, cause the compressor to malfunction, or even catch fire or explode. Therefore, the compressor is required to have a good carbon deposit tendency. .

4. Appropriate viscosity

Proper viscosity can make the air compressor have good lubrication, cooling and sealing effects under working temperature and pressure, and ensure the normal operation of machinery and equipment.
