Working Principle
The Kaishan KSCY-175/8 operates on the rotary screw compression principle. A diesel engine drives a pair of intermeshing helical rotors within the air end. As the rotors turn, air is drawn in and trapped between the rotors and the housing. The volume of this trapped air decreases as the rotors rotate, progressively raising the pressure. Oil is injected into the compression chamber to seal the gaps, lubricate the rotors, and absorb the heat of compression. The oil-air mixture then passes through a separator where the oil is extracted, cooled, and recirculated. The compressed air is discharged through a minimum pressure valve and aftercooler before being delivered to the outlet. This design ensures high efficiency, low pulsation, and a long service life.
