What is the difference between screw compressor oil and ordinary oil?

Compared with screw air compressor, the oxidation resistance and shear resistance of ordinary air compressor oil are much worse, and screw oil is much thinner.

The choice of engine oil mainly considers the environment in which it is used. Screw machine oil is generally used at 70℃~ 100℃, which is similar to automobile lubricating oil, but there are some differences.

The specific heat capacity of engine oil is also related to the choice of engine oil. The specific heat capacity of screw oil should not be too high or too low. Too high: it will lead to the untimely cooling of the oil circulating fan and the temperature will continue to rise. Too low: it will lead to too little heat carried by the oil, which will not achieve the cooling effect required by the main engine.

Main functions:

1, the screw air compressor runs at a medium speed, so it will generate a lot of heat, which needs cooling to ensure the normal operation of the machine. At this time, the special oil for screw compressor plays a cooling role, and the machine head is cooled by oil circulation to ensure the normal operation of the machine.

2. The screw main engine is pumped by two non-friction rotors, that is to say, there is a gap, and the role of screw engine oil is to play a sealing role and improve pumping efficiency.
