KAISHAN LG oil-lubricated rotary Screw Compressor adopts 0-100% infinitely variable control of displacement to realize optimal energy saving effect.

Design Characteristics of Screw Rotor Profile:

1. It fully realizes “Convex-Convex” engagement to assist in the formation of hydrodynamic lubrication film, to reduce horizontal leakage passing the contact zone, and to improve efficiency of the compressor; improve rotor processing and testing property.

2. It adopts the design thought of “large rotor, large bearing and low speed method”, thus its revolving speed is 30-50% lower than that of other brands to reduce noise, vibration, and exhaust temperature, improve rotor rigidity, increase service life, and reduce sensibility to sundries and oil carbide.

3. Its power range is 4~355KW, where 18.5~250KW applies to the compressor without direct-coupled gearbox, 200KW and 250KW apply to the compressor with Level 4 direct-coupled motor and the speed is as low as 1480 rmp.

4. It fully conforms to and exceeds requirements in GB19153-2003 Limited Values of Energy Efficiency and Evaluating Values of Energy Conservation of Displacement Air Compressors.
