Abstract: The twin-screw compressor is a kind of newly emerging compressor. Because of its high reliability, easy repair, good balance and good adaptability etc, and widely applied to such industrial departments as mine, chemical industry, power, metallurgy, architecture, machinery, refrigeration, etc. The twin-screw compressor has Occupied the market for more than 50% of the industrial, and the market share is more than 80%, also the share of the market will continue to expand in the future。So
the twin-screw compressor has a very great importance in the industry. The project is mainly to lean design the screw compressor. About Redesign of air cooling system, separation of barrels of oil and gas etc, and leaning design the oil pipeline, the base bracket just for reasonable. Redesigning of the air compressor system control circuit and the motor start control scheme, etc . The key research is about to design a new control scheme of the twin-screw compressor
Keywords: A twin-screw compressor, Lean Design, layout, System control scheme.
