Main Components
- Diesel engine (Cummins/Yuchai)
- Screw air end
- Air-oil separator tank
- Cooling system (radiator and oil cooler)
- Intelligent control panel
- Air outlet valves (G1.5, G3/4)
- Heavy-duty mobile chassis with canopy
- Intake air filter and oil filter
Working Principle
The Kaishan LGCY-23/23-25/18K operates on the principle of rotary screw compression. A diesel engine drives the male and female rotors inside the air end. 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-oil mixture then enters a separator, where oil is removed and recirculated, while clean air passes through a cooler and is delivered to the outlet. The system is regulated by an intelligent controller that adjusts engine speed and compressor load to match air demand, optimizing fuel efficiency. Safety features include high-temperature and low-oil shutdowns, ensuring reliable operation. This design delivers smooth, pulse-free air at high pressure, ideal for continuous duty in demanding environments.
