Main Components
- Diesel engine (Cummins or Yuchai)
- Twin-screw airend
- Oil separation tank
- Cooling system (radiator and fan)
- Intake air filter
- Control panel with microprocessor
- Heavy-duty chassis with tires
- Discharge valves and piping
Working Principle
The Kaishan LGCY-33/35 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 rotate, the volume between them decreases, raising the air pressure to the desired 35 bar. Lubricating oil is injected into the compression chamber to cool the air, seal clearances, and lubricate the rotors. The oil-air mixture then passes through a separation system where oil is removed and returned to the sump, while clean compressed air exits through the discharge valve. The engine speed is regulated by an electronic governor to match air demand, optimizing fuel consumption. A microprocessor controller monitors discharge pressure, temperature, and engine parameters, ensuring safe operation and automatic shutdown in case of faults. This design delivers high efficiency, low maintenance, and reliable performance in continuous duty cycles.
