Main Components
- Diesel engine (Cummins or Yuchai)
- Screw air end (two-stage)
- Air-oil separator tank
- Cooling system (radiator and oil cooler)
- Intelligent control panel
- Heavy-duty four-wheel chassis with towbar
- Fuel tank (large capacity)
- Intake air filter and oil filter
Working Principle
The Kaishan LGCY-33/35A operates on the principle of rotary screw compression. A diesel engine drives the screw air end, which consists of two intermeshing helical rotors. As the rotors turn, air is trapped between them and progressively compressed as the space decreases. The compressed air then passes through a separator to remove oil, a cooler to reduce temperature, and a filter to remove impurities before being discharged. The two-stage compression design allows the compressor to achieve high pressure (35 bar) efficiently by compressing air in two steps, with intercooling between stages to reduce thermal stress and improve efficiency. The intelligent control system continuously monitors key parameters such as discharge pressure, temperature, and engine speed, adjusting the engine throttle to match air demand. This ensures optimal fuel consumption and reduces wear. The mobile chassis and diesel power source make the compressor self-contained, capable of operating in remote areas without external power. Safety features include automatic shutdown in case of high temperature or low oil pressure, ensuring reliable and safe operation.
