我国对螺杆压缩机的研制工作已有十多年的历史,进展比较缓慢。最初是仿制国外的对称园弧型线,由于型线本身缺陷及工艺水平落后,机器的性能指标一直很低。直到73年我国自己的型线——单边非对称摆线园弧型线(见图1)研制成功后,我国的螺杆压缩机才发展到一个新阶段。 China’s development of the screw compressor has been more than 10 years of history, the progress is relatively slow. Initially imitation of the symmetrical arc-shaped lines abroad, due to defects in the profile itself and the level of technology behind, the performance of the machine has been very low. Until 73 years of our own type - unilateral asymmetric cycloid circular arc line (see Figure 1) was successfully developed, China’s screw compressor to develop to a new stage.
