The introduction of oil-free compressor

Oil-free compressor refers to a compressor that does not use lubricating oil in the compressor cylinder. The crankcase of oil-free compressor is a dry structure with large connecting rod, small hole, and double port sealed grease ball bearing. Because in operation, no lubricating oil and compressed gas source contact, so the exhaust gas does not contain oil and gas, so it is welcomed by users. But the grease sealed in the bearing will evaporate and oxidize the grease due to the temperature rise in the long-term operation, and the thickening agent in the grease will also deteriorate and lose the thickening effect. Due to the change of lipid performance, the use effect decreases sharply. If new oil is not added in time, the bearing or even the machine will be directly damaged.
