Working process of twin screw air compressor

　　After the dust or impurities in the atmosphere are filtered out by the air inlet filter, the air enters the compressor main engine through the air inlet control valve, mixes with the injected cooling lubricating oil during the compression process, and the compressed mixed gas is discharged into the oil-gas separation tank from the compression cavity. At this time, the oil-gas discharged by the compression is separated by collision, interception and gravity, and then most of the oil medium is separated Enter the oil-gas fine separator for secondary separation to obtain compressed air with little oil content. When the air is compressed to the specified pressure value, the minimum pressure valve is opened, and the compressed air is discharged to the cooler for cooling, and finally sent to the use system.
