Working Principle
The Kaishan KS300 operates on the principle of rotary screw compression. A diesel engine drives the male and female rotors inside the 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, a cooler to reduce temperature, and finally to the outlet ports. The engine speed is regulated to match air demand, ensuring efficient fuel use. An advanced control system monitors pressure, temperature, and oil level, automatically shutting down the unit if any parameter exceeds safe limits. This continuous process delivers a steady flow of compressed air for demanding applications.
