Oil-air lubrication is a lubrication device developed in recent years. It is similar to oil mist lubrication, but different from oil mist lubrication. Oil-air lubrication is similar to oil-mist lubrication. They both use compressed air as power to transport thin oil to the bearings. The difference is that oil-air lubrication does not impact the oil into a fine mist, but uses the flow of compressed air to transport the oil along the pipeline to the bearing. bearings, so condensation is no longer needed. All liquids that can flow can be transported without being limited by viscosity. The pressure of air delivery is relatively high, about 3×105Pa. The air pressure in the bearing box is also high, about 0.3×105Pa. During normal operation, the lubricating oil level is maintained in the bearing box, so the amount of oil supplied can be determined according to the actual consumption. Therefore, the lubricating oil is supplied intermittently, while the air is continuously supplied. Due to the large number of lubrication points, it was still a problem a few years ago to evenly transport the oil-air mixture to each bearing. Now a special oil distributor has been invented to solve this problem, thus enabling the development and application of oil and gas lubrication, and achieving satisfactory results.

????????The advantages of oil and gas lubrication are as follows:

? ? ????1. Conducive to environmental protection. Because there is no oil mist, the surrounding environment is not polluted.

? ? ????2． Precision measurement. Both oil and air components can be accurately measured separately and delivered to a lubrication point according to different needs. This is an economical system.

? ? ????3. It has nothing to do with the viscosity of the oil. Any oil that can flow can be transported. It does not have the problem of difficulty in atomizing high viscosity because it does not require atomization.

? ? ????4. Can be monitored. The working status of the system can be easily monitored electronically.

? ? ????5. Suitable for rolling bearings and heavy-duty rolling mill roll neck bearings. Air cooling has good results and can reduce the operating temperature of the bearings, thereby increasing the service life of the bearings.

? ? ????6. Fuel consumption is minimal. It is 1/10~1/20 of the fat consumption.
