Working Principle
The Kaishan LGCY-25/10TK operates on the principle of positive displacement using a twin-screw airend. A diesel engine drives the male and female rotors within the airend. As the rotors rotate, they trap air between their lobes and the casing, progressively reducing the volume and increasing the pressure. 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 compressed air is delivered to the outlet. The engine's speed is regulated to match air demand, optimizing fuel consumption. An advanced cooling system maintains optimal temperatures, and the control panel monitors parameters to ensure safe, efficient operation. This design provides continuous, pulse-free air delivery with high efficiency and reliability.
