Working Principle
The Kaishan LGCY-26/25K operates on the principle of positive displacement using a rotary screw mechanism. Two intermeshing helical screws (rotors) rotate within a precision-machined housing. As the rotors turn, air is drawn in through an inlet valve and trapped between the screw threads. As the rotors continue to rotate, the volume of the trapped air decreases, compressing it to the desired pressure. The compressed air then passes through a separator to remove oil and contaminants, and is cooled before being discharged. The diesel engine drives the airend via a coupling or belt, and the control system regulates engine speed and compressor load to match air demand, optimizing fuel efficiency. This continuous process ensures a steady supply of compressed air with minimal pulsation, making screw compressors ideal for high-demand applications.
