一、前 言 螺杆式压缩机问世以后,已经四十余年,但最近才做为产业用压缩机确定了它的地位。由于知道它作为容积型回转式压缩机与过去的压缩机比较有不同的特点,今后其应用范围可能日益扩大。 然而,进入实用阶段为期不久的螺杆式压缩机,不像往复式和透平式那样在理论上和实践上被人们所熟悉,所以这方面的文献也较少。 这次有机会讨论螺杆式压缩机的概况及其应用,能够帮助读者了解螺杆式压缩机,则引以为幸。
I. INTRODUCTION After the advent of screw compressors, it has been more than 40 years ago, but it was recently confirmed as a compressor for industrial use. Knowing that it has different characteristics as a rotary compressor of the volume type from that of the past compressors, its application range may expand day by day. However, the screw compressors, which have not yet reached the practical stage, are not as theoretically and practically familiar as the reciprocating and turbo-charged ones, so the literature is relatively small. This opportunity to discuss the overview of screw compressors and their applications, to help readers understand screw compressors, was fortunate.
