Working Principle

The Kaishan LGCY-45/25-37/35V operates on a two-stage rotary screw principle. Air enters through a filter and is compressed in the first stage, then passes through an intercooler before entering the second stage for further compression to 25 bar. The screw rotors, driven by a diesel engine via a coupling, mesh to reduce volume and increase pressure. Oil is injected for lubrication, sealing, and cooling. The compressed air-oil mixture then enters a separator, where oil is removed and returned to the system. The clean, high-pressure air exits through the discharge valve. A sophisticated control system monitors parameters and adjusts engine speed to match air demand, optimizing fuel efficiency. Safety devices protect against overheating and low oil pressure, ensuring reliable operation.
