The function of air compressor oil is to form a lubricating oil film on the friction surface of the relative motion of the air compressor, reduce friction and wear, reduce energy consumption, cool the friction surface, and seal the working volume of compressed air.
Main usage characteristics of air compressor oil
1. The compressor oil is in a mist form and is fully mixed with the high-temperature compressed gas. The oil is very easy to oxidize and age;
2. The compressor oil circulates at a high speed in the compressor, is repeatedly heated and cooled, and is catalyzed by metal oxidation, which aggravates the aging and deterioration of the oil;
3. The compressor oil is easy to inhale particulate impurities and suspended dust in the air during use, and is affected by corrosive gases, which accelerates the aging and deterioration of the oil.
At present, there are many manufacturers and varieties of air compressor oil, and the quality is uneven, and there are good and bad ones. The common air compressor mineral oil type on the market has a service life of mostly 1000-2000 hours, while the synthetic type has a service life of mostly 5000-6000 hours.
Common problems in the operation of screw air compressors using mineral lubricants
1. Oil change
Oil changes are frequent, and should be replaced after about 1500-2000 hours.
2. Shutdown
High temperature tripping is frequent, especially after two or three years of use of new compressors, which often shut down automatically due to excessive temperature.
3. Carbon deposition
Paint mud and carbon deposition are serious, maintenance and cleaning are frequent, the efficiency of the compressor is reduced, and even the entire air power system is affected.
4. Loss
The compressed air contains high oil content, which affects the quality of the air in the rear section. The lubricating oil evaporation loss is large and the consumption is large.
5. Maintenance
The compressor is frequently repaired and the consumption of parts is large. Generally speaking, if the screw air compressor is not maintained, it needs to be repaired once every 1-2 years.
