Oil injection screw air compressor working principle
The oil of the oil-injected screw air compressor has three functions: cooling absorbs heat of compression, sealing and lubrication
Gas path: The external air enters the machine head through the air filter and is compressed by the screw. The oil and gas mixture is discharged from the exhaust port, passes through the pipeline system and the oil and gas separation system, enters the air cooler, and reduces the high temperature compressed air to an acceptable level. .
Oil circuit: The oil and gas mixture is discharged from the main engine outlet. In the oil separation cylinder, the cooling oil is separated from the compressed air and then enters the oil cooler to remove the heat of the high temperature oil. The cooled oil is re-injected into the main machine through the corresponding oil circuit. Cool, seal and lubricate. Repeatedly.
