Main Components
- Diesel engine (Cummins or Yuchai)
- Screw air end
- Air filter and oil filter
- Oil separator tank
- Cooling system (radiator and fan)
- Control panel with gauges
- Towable chassis with axles and brakes
- Sound-attenuated canopy
Working Principle
The Kaishan LGCY-17/18-18/15TK operates on the principle of positive displacement rotary screw compression. A diesel engine drives the male and female rotors inside the screw air end. As the rotors mesh, air is trapped in the spaces between them and progressively compressed as the rotors turn. The compressed air then passes through a separator to remove oil, and is cooled by an aftercooler before being discharged. The engine's power is transmitted directly to the air end via a coupling, ensuring high efficiency and minimal energy loss. An advanced control system monitors key parameters such as discharge pressure, temperature, and engine speed, automatically adjusting the engine throttle to match air demand. This load-on-demand operation reduces fuel consumption and wear. The cooling system maintains optimal operating temperatures, even in harsh environments. Safety features include high-temperature and low-oil-pressure shutdowns, ensuring reliable and safe operation.
