Does the air of the air compressor contain oil? Why

The compressed air of the air compressor (air compressor) may contain oil, which is mainly due to a variety of factors. The following is a detailed explanation of the problem:

causes of Oil in Air of 1. Air Compressor

1. too much fuel:
   • if the oil level of the air compressor is too high, the air flow may roll the oil in the oil separator into the compressed air, resulting in excessive oil content in the discharged compressed air. Therefore, the amount of oil should be controlled within a reasonable range.
2. Oil separator problem:
   • the failure of the minimum pressure spring may cause the opening air pressure to be too low, and the pressure difference between the front and rear of the oil separator is too large, so that the flow rate of the oil and gas mixture in the tank is high, and the condensed oil on the cylinder wall and the oil separation filter element is taken away by the high-speed airflow, which affects the oil and gas separation effect.
   • Blocking or damage to the filter element of the oil separator will also reduce the separation effect and increase the oil content in the compressed air.
3. Oil return pipe blocked:
   • the blockage of the oil return pipe of the oil separator will affect the return of oil, resulting in incomplete oil separation, resulting in oil in the compressed air.
4. System leakage:
   • leaks in the air cooler system or other related systems may also cause oil to enter the compressed air system.
5. Oil problem:
   • oil that has been used for too long or deteriorated may produce foam or reduce the separation effect, increasing the oil content in the compressed air.
6. Design or manufacturing defects:
   • manufacturing defects in oil and gas barrels and trachoma in combination valves may also lead to incomplete mixing of oil and gas, resulting in oil in compressed air.
7. Improper use:
   • improper use of air compressors or long-term low-temperature operation of machines, such as large-scale pressure reduction, may also lead to an increase in oil content in compressed air.

2. solutions

for the above reasons, the following measures can be taken to reduce or avoid oil in compressed air:

1. control fuel quantity: Ensure that the refueling amount is within a reasonable range and avoid excessive oil level.

2. Regular inspection and maintenance of oil separator:

   • check the minimum pressure spring for proper operation.
   • Regularly clean or replace the oil separator filter element.

3. Keep the oil return pipe unblocked:

   • regularly check whether the oil return pipe is blocked, and clean or replace it.

4. Check system for leaks:

   • regularly check the air cooler system and other related systems for leaks, and repair them in time.

5. Replace qualified oil:

   • regularly replace the oil used by the air compressor to ensure that the quality of the oil is qualified.

6. Improved design and manufacturing:

   • air compressor parts with design or manufacturing defects shall be modified or replaced.

7. Correct use of air compressor:

   • avoid the use of air compressor or machine long-term low temperature operation and other improper use.

Through the implementation of the above measures, the problem of oil in the compressed air of the air compressor can be effectively reduced or avoided.
