Working Principle
The Kaishan KSCY-550/13 operates on the rotary screw principle. A diesel engine drives the airend, where two intermeshing helical screws rotate. As the screws turn, air is trapped between the lobes and the casing, and as the space decreases, the air is compressed. Oil is injected into the compression chamber to lubricate, seal, and cool the process. The compressed air-oil mixture then passes through a separator, where oil is removed and returned to the system, while clean air exits through the discharge valve. The intelligent control system monitors pressure and temperature, adjusting engine speed to match demand, ensuring efficient fuel use. This continuous process delivers a steady flow of compressed air at the required pressure for demanding applications.
