一、前 言 压缩机按其工作原理,通常,大体上如图1分类。离心式压缩机是将给与气体的流动能量转换为压力的;容积式压缩机通过容积变化可以提高气体压力。这些压缩机根据容量大小、压力高低及压缩介质来确定使用范围。尤其是往复式压缩机历史悠久,从一般产业部门空气机械的空气动力到各种化学装置的高压合 First, the foreword Compressor according to its working principle, usually, generally classified as Figure 1. Centrifugal compressors convert the flow energy of the supplied gas to pressure; the displacement of a positive displacement compressor increases the gas pressure. These compressors are sized based on capacity, pressure level and compression media to determine the scope of use. In particular, the reciprocating compressor has a long history, from the general industrial sector aerodynamic air machinery to a variety of high-pressure chemical devices
