Working Principle
The Kaishan KSCY-920/10K operates on the principle of positive displacement using two intermeshing helical rotors. The diesel engine drives the male rotor, which in turn drives the female rotor. As the rotors rotate, air is trapped in the spaces between them and the casing. The volume of these spaces decreases as the rotors turn, compressing the air. Oil is injected into the compression chamber to lubricate the rotors, seal clearances, and absorb heat. The compressed air-oil mixture then passes through a separator where oil is removed, and the air is cooled by the aftercooler before being discharged. The intelligent control system monitors pressure, temperature, and other parameters to ensure safe and efficient operation.
