Does oil-free screw air compressor need lubricating oil? Why

Oil-free screw air compressor, as the name suggests, refers to the screw air compressor that does not use lubricating oil for lubrication during its operation. However, this does not mean that the oil-free screw air compressor does not need any lubrication at all. In fact, the lubrication method of the oil-free screw air compressor is different from that of the traditional oil-lubricated screw air compressor. It uses other lubricating media instead of lubricating oil.

For the water-lubricated oil-free inverter screw air compressor of Shanghai Granklin Group, the lubricating medium is water. As an environmentally friendly and non-polluting lubricating medium, water plays a role of lubrication, cooling and sealing in the operation of air compressors. By injecting an appropriate amount of water into the compression cavity, a water film can be formed to reduce the friction and wear between the screws, and at the same time take away the heat generated during the compression process to ensure the efficient and stable operation of the air compressor.

Therefore, although the oil-free screw air compressor does not use lubricating oil for lubrication, it still needs other lubricating media (such as water) to ensure its normal operation. The water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group uses water as the lubricating medium, which not only realizes oil-free compression, but also ensures the performance and life of the air compressor.

It should be noted that although the water-lubricated oil-free screw air compressor has many advantages, it is also necessary to pay attention to the treatment and maintenance of water quality during use. Because impurities and microorganisms in the water may cause damage to the air compressor, it is necessary to regularly check and replace the water quality to ensure the normal operation and service life of the air compressor.
