- Screw airend
- Air filter
- Oil separator
- Cooling system
- Control panel
- Fuel tank
- Discharge valve
Working Principle
The Kaishan LGCY-21/13TK operates on the principle of rotary screw compression. A diesel engine drives the male and female rotors inside the airend. As the rotors mesh, air is trapped in the spaces between them and progressively compressed as the volume decreases. Oil is injected into the compression chamber to lubricate, seal, and cool the process. The compressed air then passes through an oil separator, where the oil is removed, and a cooler reduces the air temperature. The intelligent control system regulates the engine speed and compressor load to match air demand, ensuring optimal efficiency. The air is delivered through a discharge valve at the required pressure. This continuous process provides a steady, pulse-free flow of compressed air, ideal for demanding applications.
