Common faults of air compressors – clogging of oil and gas separator
Many users will find that the oil and gas separator will be frequently blocked during the use of the air compressor. The blockage of oil will cause problems such as poor circulation of the oil circuit, severe high-temperature shutdown of the machine, etc., making the air compressor unable to work normally. So what causes the blockage?
- Surrounding environment
The location requirements for air compressor work are less dust, clean air and good ventilation. When dust, particles and other impurities in the air enter the air compressor system, they will chemically react with the lubricating oil, resulting in carbon deposits and sludge. For example, industries such as cement, coal mines, and textiles must do a good job in air filtration, as well as timely maintenance and replacement of “three filters and one oil”.
- Lubricating oil is low
Lubricating oil with poor oxidation resistance is not suitable for use. Even if the working time is short, carbon deposits and jelly will be generated to block the oil.
- Mix oils of different oil products
Do not mix different grades and types of air compressor lubricants. Also do not mix compressor oils from different manufacturers.
- The quality of “three filters” is poor
An air filter with poor filtration accuracy will prevent some dust particles in the air from being intercepted, and will directly enter the air compressor system, causing excessive load on the oil filter and oil components, resulting in blockage. Impurities, oil oxides, worn metal particles, etc. that enter the air compressor system due to poor oil filtration accuracy, some of them are intercepted on the oil filter layer, and the other part of the impurities has been circulating in the machine until it rises to the oil, and stays in the oil after separation. In the filter layer, the oil is blocked prematurely.
- Too much moisture in the filter material
Excessive water on the oil filter material will cause the filter material to swell and shrink, reducing the effective separation area of the oil, resulting in an increase in the resistance of the oil and premature blockage of the oil.
