摘　　要：目前国内外干式双螺杆压缩机大多数直接采用了喷油螺杆压缩机的型线,一般通过改变齿数比,适应干式螺杆压缩机低压比和大气量的需求。通过对干式双螺杆空压机型线开展优化设计,将螺杆压缩机型线中瞬时啮合的曲线变为逐点啮合的曲线,避免压缩机螺杆齿面啮合的泵吸作用,从而降低压缩机气动噪声,改善压缩机运行环境。At present,most dry twin screw compressors directly use the profile of oil injection screw compressor,generally by changing the tooth ratio,to adapt to the low-pressure ratio of dry screw compressor and large gas requirements.Through the optimization design of dry twin-screw air compressor profile,the instantaneous meshing curve of screw compressor profile is changed into point-by-point meshing curve,avoiding the pumping action of screw tooth surface meshing,thus reducing compressor aerodynamic noise and improving compressor operating environment.
