There are four common causes of oil plugging in screw air compressors:
1, screw air compressor surrounding environment. The environment surrounding the screw air compressor is corrosive. For example, sulfides, water, chemicals used for cleaning, etc. evaporate in the air in some cases. The high temperature of the machine itself accelerates the oxidation of the oil. The screw air compressor system enters into a chemical reaction with the engine oil to generate carbon deposits, sludge, etc. Some of the impurities enter the engine oil circulation system and are intercepted by the oil filter. The other part of the impurities will rise with the oil and gas mixture to the oil. When the gas passes through the oil, these Impurities remain on the oil filter paper, clogging the filter holes, the resistance of the oil gradually increases, so that the oil needs to be replaced in advance within a short time.
2. Screw air compressors do not use qualified air filters, oil filters, and oils, and they all exist in one or more conditions. Air filtration with poor filtration accuracy will make dust particles in the air unable to be intercepted, and will directly enter the screw air compressor system. The oil filter and oil load will be too large, leading to blockage; impurities, oil oxides entering the screw air compressor system Due to the poor accuracy of oil filter filtration, worn metal particles, etc., some of the impurities are intercepted on the oil filter layer, and the other part of the impurities has been circulated in the machine until it rises up to the oil. After separation, it is retained in the filter layer of the oil, causing the oil to be separated prematurely. Blockage; Oil with poor oxidation resistance should not be used. Even if the working time is short, it will produce carbon deposits and jellies, blocking the oil.
3. There is a leak in the air line between the screw air compressor and the air inlet of the host. Causes of leakage are as follows: air filter is not installed; air filter assembly contact area is not flat; air filter and assembly contact surface with dirt attached to the above, leading to leakage; air filter surface of the elastic contact pad put away ; Air filter or air filter assembly rupture and so on.
4. Excessive moisture on the oil filter material of the screw air compressor causes the filter material to swell and shrink pores, so that the effective separation area of ​​the oil is reduced, resulting in increased oil resistance and premature blockage of the oil.

Screw air compressor oil blocking common 4 reasons
The air-oil separator elements of the screw air compressor are also called oil-air separators, oil separators, oil separators, oil separators, etc., which are generally referred to as oils in the industry. The oil has a long life, because when it separates the oil and compressed air, the impurities also stay on its filter material, blocking the filter pores, but the resistance is too large, resulting in increased power consumption of the air compressor, which is not conducive to Energy-saving and emission-reduction, so when the oil is plugged to a certain pressure value, it needs to be replaced.
