- Discharge valve and piping
Working Principle
The Kaishan LGCY-30/8TK operates on the principle of positive displacement using a twin-screw airend. A diesel engine drives the male and female rotors, which mesh to trap and compress air. As the rotors turn, the volume between them decreases, raising the air pressure. The compressed air then passes through a separator to remove oil and impurities before being discharged. The engine's power is transmitted via a coupling or belt, and the system includes valves, coolers, and filters to ensure efficient operation. The control system regulates engine speed and air intake to match demand, optimizing fuel consumption. This design provides smooth, pulsation-free air delivery with high efficiency and reliability, making it suitable for continuous heavy-duty use.
