The secret between compressor oil and compressor, dry goods!

The secret between compressor oil and compressor, dry goods! As a result of the lubricant manufacturer’s publicity, users do not know much about it

The influence of the compressor itself on the real life of the compressor oil, especially the oil-injected screw air

compressor oil, the real situation is: even the same compressor oil is used in different types, different parameters, different compression media and different working conditions. On board, the real life span is also very different. See the following analysis: 1) If the exhaust 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 speed of the air compressor oil is very different, and the discharge pressure is a low pressure of 0.3 MPa The real life of the lubricating oil of an air compressor 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) Two-stage compression normal-pressure oil-injected screw air compressorBecause of the low oxygen partial pressure at each level and low exhaust temperature, it is not only energy efficient, but also the real life of the 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 the frequency conversion period, the compressor's shearing effect on the lubricating oil is lighter than that of the ordinary volumetric air compressor, 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 lengthens 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.
