The specific working condition of the air compressor determines that the used air compressor lubricating oil needs to have the following main properties: (1) the oil product is easy to oxidize and deteriorate due to continuous contact with high-temperature and high-pressure oxygen in compressed air in the circulating use process, and has excellent oxidation stability, so that the oil product can be safely used for a long time; (2) the carbon deposition tendency is low, and the carbon deposition resistance tendency of the air compressor oil is crucial to the reliable operation of the air compressor; (3) good oil-water separation performance; (4) the lubricating oil has good viscosity-temperature performance, the viscosity of the lubricating oil cannot be too high at low temperature, and the lubricating oil can be fully distributed to a lubricating part; at high temperature, the viscosity of the lubricating oil cannot be too low, and the lubricating oil forms a thick enough oil film at the lubricating part to ensure good lubrication; (5) the oil product is easy to generate foam in the recycling process of the air compressor oil, and abnormal phenomena such as increased oil consumption, overtemperature and the like are caused, so that the air compressor oil is required to have excellent anti-foaming performance; (6) the corrosion-resistant antirust paint has good corrosion-resistant antirust performance, and ensures the normal operation of equipment; (7) the device has a proper flash point, and the safe operation of the device is ensured.
