With more and more research on air compressor applications, more and more industries are using air compressor equipment, so the management and maintenance of air compressors is inevitable. However, there are some misunderstandings in the maintenance process, such as replacing screw air compressor oil, which seems to be simple, but in fact is not so easy. Improper handling can lead to a number of problems and failures, resulting in serious consequences. So how to change the oil of screw air compressor?

If there is not much mud in the air compressor at the time of oil change, you can put the air compressor oil into half of the barrel, run for 15 minutes to 1 hour, then add new oil and resume normal operation. If there is too much carbon accumulated in the mud, you can disassemble the air compressor cylinder, remove the mud and carbon manually, then clean the mud and carbon with special cleaning agent, add cleaning oil to clean for one to two hours, discharge the cleaning oil, and restore the normal operation of the equipment by new air compressor oil. Otherwise, the performance of the air compressor oil may be damaged or affected.

Secondly, each time the oil is replaced, the old oil should be discharged and not mixed or reused. This is because when the color of air compressor oil remains the same, the consumption of additives may exceed a certain limit and it no longer functions as a lubricant. Customers should pay attention to different brands of air compressor oil, different grades of air compressor oil do not mix, which is the advantage of air compressor oil, but also a limit, oil change should also replace the oil filter, oil filter parts, gas separation filter, oil bypass filter, check the air filter, temperature control warning, check valve, filter in good condition.

How to change the oil of screw air compressor? It is recommended not to choose a fixed time for oil change, because the environment, mechanical equipment and other impurities will accelerate the aging of the oil. To prevent carbon accumulation and focus, the viscosity and color of the oil should be observed during use (every 300 hours), but the quality of air compressor oil cannot be judged by color.

When using air compressor, you should make a good habit of recording and designate the person in charge. Screw air compressor oil is a kind of oil with special performance and must be managed by a person in charge to prevent accidents from mixed use. After the air compressor oil is used up, tighten the cylinder cover, and there is no tool to open the cover nearby. How to change the oil of screw air compressor? If oil evaporation loss is found to be large, the oil and gas separator should be checked first for perforation and other problems. The above are several oil change skills in the air compressor maintenance process, which will help significantly in the stable development and operation of air compressor equipment and will reduce some unnecessary troubles, and the stable air compressor oil should reach a certain service life.
