About the installation of oil and gas separation filter element and the reasons for the effect

Fistly, installation precautions

1.the correct placement of seals, and there should be electrostatic conductivity measures, oil-resistant seals can work normally at a high temperature of 120 ° C.

2.re-straight installation of the external intake oil, the return pipe must be long enough, and straight to the oil, to reach the bottom end cover slope concave.

3.the selection of high-quality lubricating oil, lubricating oil system should not be mixed with any foreign matter, the oil should be replaced regularly.

4. When installing the rotary type oil and gas separator, the return pipe must be placed at the bottom of the separator.

Secondly, the oil partial pressure difference rises too fast

The oil partial pressure difference is formed when the solid particles in the compressed air remain in the filter layer of the oil core.

1.air compressor air filter and oil filter have a certain life, both must be replaced on time should not use low quality

Air filter, oil filter.

2.when the compressor running temperature is high or the oil quality is low, the oil is easy to age, oxidize, form a glue, block, pollute the filter element, make

The pressure difference rises too fast.

3.the air compressor oil and gas separation tank should be regularly drained, otherwise the filter element is easy to rust.

Thirdly, Excessive oil consumption (excessive oil content in exhaust)

1.the return pipe is blocked or the return pipe does not work, in this case, a large amount of oil is stored in the oil core, and the oil is taken out by the gas.

2.Excessive refueling in the oil tank leads to high oil content of the gas entering the oil core, increasing the load of the oil core and reducing the separation effect.

3.the design of the oil tank is unreasonable, the diameter of the oil and gas barrel is small or the mechanical separation structure is poor.

4.the design of the selection of oil core is unreasonable, the size of the oil core is too small, resulting in poor separation effect.

5.the sealing ring, pad material is not suitable, not oil resistance or poor position, resulting in oil leakage at the seal.

6.the compressor is used to reduce pressure, the exhaust volume is larger, the filter element separation effect is reduced, the residual oil amount is increased.

7.the temperature of the compressor is too high, the oil evaporation is accelerated, and the oil mist concentration is large when the oil core is reached.
