一、前 言 随着我国工业生产和科学技术的迅速发展,对压缩机产量和质量提出了越来越高的要求。为了适应当前压缩机生产发展的新形势,近年来国内对回转式压缩机做了很多工作,其中螺杆式压缩机已经成批生产,滑片式压缩机也有试制生产。 I. Introduction With the rapid development of China’s industrial production and science and technology, higher and higher requirements have been put on compressor output and quality. In order to adapt to the current situation of compressor production and development, in recent years a lot of work has been done on the rotary compressor in China, among which the screw compressor has been mass-produced and the vane compressor has trial production.
