Working Principle
The Kaishan LGCY-23/23-25/18 operates on the principle of positive displacement using a rotary screw mechanism. Air is drawn into the compressor through an intake valve and enters the airend, where two intermeshing helical screws rotate. As the screws turn, the space between them decreases, compressing the air. Oil is injected into the compression chamber to lubricate, seal, and cool the process. The compressed air then passes through an oil separator, where most of the oil is removed and recirculated. The air is further cooled in an aftercooler and delivered through outlet ports at the required pressure. The diesel engine drives the airend via a coupling, and the intelligent control system regulates engine speed and air intake to match demand, optimizing fuel efficiency. This design ensures smooth, continuous operation with minimal vibration and wear, making it suitable for heavy-duty applications.
