Air compressor oil level overview:
In the running state, the oil level of the compressor should be kept between the minimum and maximum oil levels. Too much oil will affect the separation effect, and too little oil will affect the lubrication and cooling performance of the machine. During the oil change cycle, if the oil level is lower than the minimum The oil level should be replenished in time, the method is:
①Stop the machine and wait for the internal pressure to be released (confirm that there is no pressure in the system), then pull down the main switch of the power supply.
②Open the filler port on the oil-gas separation tank, and add a proper amount of cooling lubricating oil.
③For the oil change time after the air compressor is in normal operation, refer to the regular maintenance table.
Air compressor lubrication method:
1. Pressure lubrication method - use machinery (such as oil pump, lubricator) to automatically press lubricating oil to lubricate parts, also called pressure lubrication method. This method is used in large and medium-sized compressors with crossheads.
2. Splash lubricating method--the oil rod installed on the connecting rod will throw the oil and splash it to the lubricating parts for lubrication, so the cylinder and the moving mechanism can only use the same lubricating oil. This method is mostly used in small compressors without crossheads. The disadvantage is that the oil is not easy to filter, and the oil level must be strictly controlled.
3. Spray-in lubrication method - the sprayed oil mist follows the gas into the cylinder and other lubricating places, such as ultra-high pressure compressors, sliding vane compressors and screw compressors are all lubricated by oil spraying.
4. Drip oil lubrication method - use oil cups and oil pipelines to send lubricating oil to the parts that should be refueled, or use an oil pot to fill lubricating oil on time.
5. Oil ring lubrication method - use the rotating shaft to drive the oil ring that is movably sleeved on the shaft, and the oil ring will bring the oil in the oil pool into the bearing and enter the circulation lubrication.
