Main Components
- Screw airend
- Diesel engine (e.g., Weichai/Deutz)
- Air intake filter
- Oil separator tank
- Minimum pressure valve
- Aftercooler with moisture separator
- Electronic controller (PLC)
- Heavy-duty towing chassis with suspension
Working Principle
The Kaishan KSCY-220/8X operates on the rotary screw compression principle. A diesel engine drives two intermeshing helical rotors inside the airend. As the rotors turn, the volume between them decreases, compressing the air drawn in through the intake filter. Oil is injected into the compression chamber to seal the gaps, lubricate the rotors, and absorb heat. The compressed air-oil mixture is discharged into a separator tank, where the oil is removed and cooled before being recirculated. The clean compressed air then passes through a minimum pressure valve and an aftercooler, reducing its temperature and condensing moisture. The final air is delivered to the outlet port at the required pressure of 8 bar. The engine speed is regulated by an electronic governor to match air demand, ensuring optimal fuel efficiency and stable output.
