Oil-free air compressor by what lubrication

Oil-free air compressor mainly rely on the following ways of lubrication:

1. Dry lubrication: There is no excess lubricating medium in this way, but a special solid lubricating material, such as polytetrafluoroethylene (PTFE), will be coated on the surface of the key components inside the compressor. These materials have excellent high temperature resistance and wear resistance, which can reduce energy consumption and improve the working efficiency of the compressor.

2. Water lubrication: In this way, water is used as the lubricating medium to lubricate the moving parts inside the compressor. Water lubrication not only has a good cooling effect, effectively reduces the internal temperature of the compressor, but also reduces wear. At the same time, due to the high cleanliness of the water, this also helps to improve air quality.

3. Self-lubricating materials: Some oil-free air compressors use special materials to make key moving parts. These materials can produce self-lubricating effect when they contact each other, thereby reducing friction and wear. For example, in some miniature reciprocating piston compressors, this is achieved by using piston rings and cylinder walls with self-lubricating properties.

4. Other lubrication methods: In addition to the above methods, there are some oil-free air compressors that may use other lubrication methods, such as resin lubrication, but these methods are currently used less.

in general, the oil-free air compressor achieves efficient and safe operation in an oil-free environment by adopting these special lubrication methods. These lubrication methods not only reduce friction and wear, but also improve air quality, making oil-free air compressors particularly suitable for applications with strict air quality requirements.
