Three major judgment methods for 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, combined with temperature, moisture, oxygen, impurities and other factors, the lubricating oil is highly prone to deterioration and affects the operation of the equipment.
The deterioration of air compressor lubricating oil will affect the loss of parts and shorten its service life, and it can cause major equipment failure in severe cases. Therefore, to understand the identification method of lubricating oil deterioration, and to do a good job in quality monitoring of lubricating oil, it is of great significance for timely replacement of lubricating oil and protection of equipment.
01
Observation
The flow state of the lubricating oil can be used as a basis for judging whether or not the product is deteriorated. Raise the beaker containing the oil to be tested, slowly pour it into the empty beaker on the table, and observe the flow of the lubricant while standing. If it is uniform, slender, continuous flow state, it indicates that the oil quality is better; The speed is suddenly large and small, and when the amount of fluid is too small, it proves that deterioration has occurred. The initial color of the lubricating oil is very light, and the quality of the lubricating oil is very light. After a period of use, the color of the oil will gradually deepen and become turbid. According to experience, the color is too dark or too turbid to be used. The oil is sampled and tested by pH test paper. If the acid value exceeds the standard, the oil needs to be replaced if the oxidation is serious.
02
Touch method
After the lubricating oil has deteriorated, the touch will also change. This is the basis for judging whether the lubricating oil has deteriorated. Good quality lubricating oil, when the finger is ground, the lubrication is strong, and there is no obvious friction. If the finger feels sharp friction during the grinding process, it proves that the impurity content in the lubricating oil exceeds the standard and should be replaced immediately.
03
Detection method
By regularly sampling the lubricating oil, the professional physical and chemical equipment is used to test the physical and chemical indicators of the lubricating oil. According to the test results, the report on whether the lubricating oil can continue to be used is given, and the oil is replaced according to the report. During the operation of the screw air compressor, high-quality, clean lubricating oil is selected, which can avoid the premature deterioration of the air compressor oil during use and ensure the normal operation of the equipment.
It is recommended to use ultra-high cost performance. The screw air compressor oil series with the advantage of “synthetic oil quality, mineral oil price” is developed and produced by Pulanka Lubricant Technology Co., Ltd., with low unit price and long service life of 4000+. hour. Provides long oil life and effective lubrication protection for screw air compressors operating at high temperatures and harsh operating conditions.
