How oil-free compressors are lubricated

The oil-free compressor mainly adopts the following lubrication methods:

air lubrication: This method reduces the friction between machine parts by increasing the water molecules in the air. During operation, oil-free compressors produce water molecules in the compression chamber, and then use pipes to transport these water molecules to the bearings and sliding surfaces to achieve a lubricating effect. This lubrication method can not only reduce the friction between the components, but also play a role in cooling.

Polymer lubrication: This is a new type of oil-free lubrication technology that achieves lubrication by coating polymer materials on the surface of machine parts. Polymer lubrication has excellent lubrication performance, which can effectively reduce the wear and friction loss between components. At the same time, it can also reduce the noise and vibration generated by the machine during operation, thereby improving the working efficiency of the machine.

Water lubrication: Especially in oil-free screw air compressors, water lubrication technology is widely used. This technology uses water to replace traditional lubricants to achieve the four major effects of lubrication, cooling, sealing and noise reduction. Due to the use of water as a lubricant, the discharged water does not require special treatment and meets environmental protection requirements. At the same time, water lubrication also makes the compression process closer to isothermal compression and improves the compression efficiency.

In summary, oil-free compressors achieve efficient and environmentally friendly operation through a variety of innovative lubrication methods, such as air lubrication, polymer lubrication and water lubrication. These lubrication methods not only reduce the friction and wear between components, but also improve the working efficiency and service life of the machine.
