Oil free air compressor maintenance

Oil-free screw air compressors are widely used in manufacturing and chemical industries.
Compared with oil-lubricated air compressors, oil-free air compressors are easy to maintain and have relatively lower maintenance costs. Daily preventive maintenance of oil-free air compressors can help extend the service life.

Benefits of daily maintenance of oil-free air compressors
1. Food and medical industries have high requirements for the purity of compressed air, so daily maintenance of oil-free air compressors is required to ensure that the air compressor parts are free of pollution.

2. Through maintenance during daily use, the service life of oil-free air compressors can be extended and the frequency of air compressor replacement can be reduced.


Tips for maintenance of oil-free air compressors
1. Control pressure
Excessive or low operating pressure will affect the output efficiency of oil-free air compressors and even cause them to be scrapped.

2. Regularly discharge sewage from the gas tank
The sewage in the gas tank should be discharged once a week to prevent sewage accumulation from affecting the operation of the air compressor.

3. Replacement of filters
When the operation reaches 250~300 hours, the filter should be checked to keep the filter clean to effectively reduce the failure rate of the air compressor.

4. Electrical system inspection
Regularly check whether the power wiring is loose or aging to ensure stable operation of the electrical system. At the same time, regularly calibrate the sensors of the control system to prevent the equipment from failing to adjust the operating parameters normally.

5. Check for leaks
Check the working environment of the air compressor. If a leak is found, please contact the manufacturer's engineer to deal with the leak.

6. Radiator cleaning
The radiator is a component of the air compressor cooling system. By cleaning the dust and oil on the surface of the radiator, the heat dissipation effect is prevented from decreasing and affecting the operating efficiency of the air compressor.

7. Noise and vibration detection
Pay attention to the noise and vibration level of the air compressor on a daily basis. Abnormal sounds may be problems with the air compressor components and need to be repaired in time.

8. Lubrication system maintenance
Oil-free air compressors do not use lubricating oil during the compression process, but mechanical transmission parts still need lubrication, such as motor bearings and gearboxes. The lubrication of bearings, etc. needs to be checked regularly, and the lubricating grease should be replaced according to the frequency recommended in the user manual.

Through daily maintenance of oil-free air compressors, not only the use time of the equipment is increased, but also the operating efficiency of the air compressor is improved.
