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. By designing the project, the volumetric efficiency is 70%, the compressed temperature is more 80℃。It is very important to design and research a twin-screw compressor in industrial. The project is to design a universal twin-screw air compressor, and to adopt single side asymmetric swept line unilaterally and dowel tooth circular rotor profile. There are six lobes on the female rotor and four lobes on the male rotor. The aim of designing a new rotor profile is to optimize the contact line length, blowhole area and clearance volume. That can improve the mechanical performance of a twin-screw compressor further. The project is mainly to research a twin-screw compressor rotor profile, geometry characteristic, mechanics analysis, thermodynamics calculation [Keywords] A twin-screw compressor, rotor profile, mesh curve, tooth space volume.
