How to solve the problem of oil spraying out from the air filter of the screw air compressor?

In industrial production, screw air compressors (referred to as screw air compressors) are widely used in various manufacturing companies due to their advantages such as high efficiency, reliability, and wide application range. However, during the operation of the equipment, oil spraying out of the air filter is a common and serious problem. This will not only lead to waste of lubricating oil, but may also affect the normal operation of the equipment and even cause safety hazards. Therefore, timely and accurate diagnosis and resolution of the problem of oil spraying out of the air filter is crucial to ensure stable operation of the equipment and production safety.

1. Hazards of oil spraying out of the air filter

Oil spraying out of the air filter will cause the following hazards to the normal operation of the screw air compressor:

1. Waste of lubricating oil:

The lubricating oil sprays out from the air filter, resulting in a decrease in oil volume, increasing lubricating oil consumption and operating costs.

2. Insufficient equipment lubrication:

The loss of lubricating oil will cause the moving parts of the equipment to not be fully lubricated, increase friction and wear, and shorten the service life of the equipment.

3. Environmental pollution:

The sprayed lubricating oil will pollute the environment around the equipment and affect the cleanliness and safety of the workplace.

2. Analysis of the reasons for oil spraying outward from the air filter

2.1 Oil separator core failure

1. Oil separator core blockage:

Cause: After long-term use of the oil separator core, oil and impurities accumulate, causing blockage.

Impact: Blockage of the oil separator core will lead to reduced oil separation efficiency and incomplete oil-gas separation.

2. Damage to the oil separator core:

Cause: Damage caused by aging of the oil separator core material, external force damage or improper installation.

Impact: The damaged oil separator core cannot effectively separate oil and gas, causing the lubricating oil to enter the air filter with the compressed air.

3. Improper installation of the oil separator core:

Cause: The oil separator core is not installed firmly or has poor sealing.

Impact: Improper installation will lead to incomplete oil-gas separation and lubricating oil entering the air filter.

2.2 Lubricating oil problem: excessive lubricating oil, inappropriate lubricating oil viscosity, and emulsified lubricating oil

3. Diagnostic method for oil spraying outward from the air filter

1. Observe the oil spraying situation:

Check the oil spraying position: Observe the specific position of the oil spraying to determine whether there is a problem with the oil separator core or other parts.

2. Check the oil separator core:

Remove the oil separator core: Remove the oil separator core and check whether it is blocked, damaged or improperly installed.

3. Check the oil separator tank pressure:

Check the minimum pressure valve: Check whether the minimum pressure valve is working properly and whether it is stuck or damaged.

4. Check the return oil pipe:

Check the blockage: Check whether the return oil pipe is blocked and clean it if necessary.

5. Check the lubricating oil:

Check the oil level: Make sure the lubricating oil level is within the normal range.

Check the oil quality: Take samples to check the color, viscosity, impurity content, etc. of the lubricating oil to determine whether it needs to be replaced.

6. Check the air filter:

Check the blockage: Check whether the air filter is blocked and replace or clean it if necessary.

IV. Treatment measures for oil spraying outward from the air filter

1. Replace the oil separator core:

Regular replacement: Regularly replace the oil separator core according to the use of the equipment and the quality of the oil.

2. Adjust the oil separator tank pressure:

Check the minimum pressure valve: Repair or replace the faulty minimum pressure valve to ensure its normal operation.

3. Control the amount of lubricating oil:

Check the oil level: Check the oil level in the oil tank regularly, and replenish or discharge excess lubricating oil in time.

4. Use lubricating oil with appropriate viscosity:

Choose the appropriate viscosity

5. Deal with air filter blockage:

Replace or clean regularly: According to the usage, replace or clean the air filter regularly to ensure its smoothness.

6. Control the equipment load:

Reasonably adjust the operating parameters: According to the actual gas consumption, reasonably adjust the equipment operating parameters to avoid overload operation.

The outward oil spraying from the air filter of the screw air compressor is a complex problem, and its reasons involve the oil core, oil tank pressure, lubricating oil and air filter. Through timely and accurate diagnosis and effective treatment measures, the problem of outward oil spraying from the air filter can be effectively solved to ensure the safe and efficient operation of the equipment. I hope that this article can provide valuable reference and guidance for enterprises, help enterprises effectively deal with the problem of outward oil spraying from the air filter, improve the reliability of equipment operation, and reduce operating costs.
