Working Principle
The Kaishan LGCY-17/18-18/15T operates on the principle of positive displacement screw compression. Air is drawn through a heavy-duty filter into the first-stage screw airend, where two intermeshing rotors compress the air. The compressed air then passes through an intercooler to reduce its temperature before entering the second-stage airend for further compression to the final 18 bar pressure. After the second stage, the air goes through an aftercooler and moisture separator to remove condensate. The diesel engine drives the airend via a coupling or belt system, and an electronic control unit monitors and adjusts engine speed and compressor load to match air demand, optimizing fuel efficiency. A safety valve and automatic shutdown system protect the compressor from overheating, overpressure, and low oil pressure, ensuring reliable operation.
