- Fuel tank
Working Principle
The Kaishan LGCY-27/25-29/18 operates on the principle of rotary screw compression. A diesel engine drives the male and female rotors inside the airend. As the rotors mesh, they trap air and progressively reduce its volume, increasing pressure. Oil is injected into the compression chamber to lubricate, seal, and cool the process. The compressed air then passes through a separator to remove oil, a cooler to reduce temperature, and a filter to ensure cleanliness. The intelligent control system monitors pressure, temperature, and engine parameters, automatically adjusting the engine speed and compressor load to match demand. This ensures optimal fuel efficiency and prevents overpressure. The dual pressure capability is achieved by adjusting the control valve settings, allowing the operator to select between 25 bar and 18 bar based on application requirements. The entire process is contained within a sound-attenuated enclosure, reducing noise and protecting components from dust and weather.
