Oil-free air compressors are lubricated by what?

According to the different lubrication methods, air compressors can be divided into two types: one is an oil-free air compressor, and the other is an oil-based air compressor, which uses lubricating oil to lubricate the components to reduce the wear between the components. However, there is no lubricating oil involved in the operation of the oil-free air compressor. Therefore, the compressed air is not polluted by the lubricating oil. How do oil-free air compressors lubricate?

Lubrication method of oil-free air compressor:

1. The oil-free air compressor does not need to add lubricating oil. It is lubricated by high speed or water, and the discharged compression will have no lubricating oil particles.

2. The oil-free air compressor mainly replaces oil with water, realizes the four functions of lubrication, cooling, sealing and noise reduction, provides high-quality oil-free air, is pollution-free, and the discharged water does not need special treatment, which meets the requirements of environmental protection.

3. It should be noted that the compressed air of the oil-free air compressor is not 100% oil-free. Since air contains a small amount of oil, the compressed gas also needs to be treated to a certain extent.

The above is the way to lubricate the oil-free air compressor. I hope it can help everyone. In the air compressor system, no lubricating oil is added, and pure water is used for smoothing. No lubricating oil participates in the work of the air compressor throughout the process. Therefore, after compression There is no lubricating oil in the air, so it is called an oil-free air compressor.
