Oil-free air compressor is a kind of efficient and safe compressed air equipment, its working principle is to generate power by compressed air. Due to the oil-free design, there is no need to use traditional lubricants to protect internal mechanical parts. However, although oil-free air compressors do not need to use oil, they still need regular maintenance and maintenance to ensure their normal operation and extend their service life.
Common maintenance work for oil-free air compressors includes cleaning filters, checking and replacing seals, and regularly checking motors and cooling fans. In addition, the oil-free air compressor also needs to carry out regular inspection and cleaning of the exhaust pipe to ensure the quality and flow of compressed air.
In addition to routine maintenance work, oil-free air compressors also need to use some special lubricants to protect and lubricate the internal seals and bearings. These lubricants are usually oil-free or low-oil to avoid contamination of compressed air.
The following are some commonly used oil-free air compressor lubricants:
1. Polytetrafluoroethylene (PTFE) lubricant: PTFE is an oil-free lubricant with strong lubricating properties and high temperature resistance. It can be used to lubricate seals and bearings, reducing wear and friction.
2. High temperature grease: For some oil-free air compressors used in high temperature environments, you can choose some high temperature grease to protect the internal parts. These greases have high temperature resistance and lubrication properties, and can work stably at high temperatures.
3. Lubricating oil additives: Some oil-free air compressors can use some lubricating oil additives to improve the lubrication effect of seals and bearings. These additives are usually oil-free or low in oil and can provide better sealing properties and lubrication properties.
4. Pneumatic lubricant: Pneumatic lubricant is an oil-free lubricant with low volatility and high lubrication performance. It can be used to lubricate the seals and bearings of oil-free air compressors, reducing wear and friction.
It should be noted that when using lubricants, the appropriate products should be selected according to the model of the oil-free air compressor and the requirements of the manufacturer. Different oil-free air compressors may have different requirements for lubricants, so the advice of manufacturers or technicians should be consulted when selecting lubricants.
To sum up, oil-free air compressors do not need to use traditional lubricants, but still need to use special oil-free lubricants to protect and lubricate the internal seals and bearings. Choosing the right lubricant is crucial to the normal operation and extended service life of oil-free air compressors.
