The secret that I have to say between the compressor oil and the compressor has increased knowledge!

As a result of the publicity of the lubricant manufacturer, users do not know much about the impact of the compressor itself on the real life of the compressor oil, especially the oil-injected screw air compressor oil. The truth is: even the same type of compressor oil is used in different types , Compressors with different parameters, different compression media and different working conditions, the true life is also very different.

　　See the following analysis:

　　1) If the discharge temperature of the oil-injected screw air compressor is reduced by 8~10℃, the life of the compressor oil will be doubled;

2) The discharge pressure of a single-stage oil-injected screw compressor ranges from 0.3 to 1.3 MPa. Due to the difference in discharge temperature and oxygen partial pressure, the oxidation rate of air compressor oil is very different. The low pressure air compressor with a discharge pressure of 0.3 MPa The real life of lubricating oil is 3~5 times longer than that of an air compressor with a discharge pressure of 1.3MPa;

　　3) The lubricating oil of nitrogen compressor is not affected by oxygen, and its real life is much longer than that of the same type of air compressor;

　　4) The oil acid value of similar screw compressors that compress carbon dioxide gas is easy to exceed the standard, and the real life is short;

　　5) The two-stage compression normal pressure oil-injected screw air compressor has low oxygen partial pressure at all levels and low exhaust temperature not only has high energy efficiency, but also the real life of lubricating oil is about 2 times longer than that of the same type of single-stage air compressor;

　　6) The compressor oil life of the single-stage screw air compressor with high compression ratio is short;

7) Frequency conversion oil-injected screw air compressor due to the low exhaust temperature during frequency conversion, the compressor's shearing effect on lubricating oil is lighter than ordinary volumetric air compressors, the real life of the lubricating oil is long, the frequency conversion time and the frequency conversion depth are different, and the lubrication The real life of oil is different;

8) In order to improve energy efficiency, some air compressor manufacturers and users have increased the fan of air-cooled oil-injected screw air compressors and lowered the discharge temperature of the screw compressor, which not only reduces power consumption, but also extends the compressor The service life of oil achieves the effect of killing two birds with one stone;

　　9) The true life of centrifugal compressor oil and piston compressor oil is much longer than that of oil-injected screw air compressors
