3 methods to judge the deterioration of air compressor lubricating oil

Screw air compressor is one of the most widely used air compressors. During the use of lubricating oil, due to its own service life and the influence of various factors such as temperature, moisture, oxygen, impurities, etc., the lubricating oil is easily deteriorated and affects the operation of the equipment. 3 methods for judging the deterioration of air compressor lubricating oil

　　 The deterioration of air compressor lubricating oil will affect the loss of parts, shorten their service life, and cause major equipment failures in severe cases. Therefore, understanding the methods of identifying deterioration of lubricating oil and monitoring the quality of lubricating oil is of great significance for timely replacement of lubricating oil and protection of equipment.

　　① Observation method

　　The flow state of lubricating oil can be used as a basis for judging whether it has deteriorated. Raise the beaker containing the oil to be tested, and slowly pour it into the empty beaker on the table. Observe the flow of lubricating oil while pouring. If it shows a uniform, slender, continuous flow state, it indicates that the oil is of good quality; if it shows flow When the speed fluctuates rapidly, and the fluid volume fluctuates, it proves that it has deteriorated.

　　 The initial color of lubricating oil is very light, and the color of good quality lubricating oil is very light. After a period of use, the color of the oil will gradually darken and become turbid. According to experience, if the color is too dark or too turbid, it cannot be used. Sampling oil, use pH test paper to test and observe. If the acid value exceeds the standard and the oxidation is serious, the lubricant needs to be replaced.

　　② Touch method

　　 After the lubricating oil has deteriorated, the touch will also change, which is the basis for judging whether the lubricating oil has deteriorated. Good quality lubricating oil has a strong sense of lubrication and no obvious friction during finger grinding. If you feel obvious friction during finger grinding, it proves that the content of impurities in the lubricating oil exceeds the standard and should be replaced immediately.

　　③ Detection method

　　 Through regular sampling of lubricating oil, the use of professional equipment to detect various physical and chemical indicators of lubricating oil, according to the test results, give a report on whether the lubricating oil can continue to be used, and replace the oil according to the report.

　　 During the operation of the screw air compressor, selecting high-quality and clean lubricating oil can largely avoid the premature deterioration of the air compressor oil during use and ensure the normal operation of the equipment.
