本文对多级离心压缩机的喘振动态特征进行了分析。采用稳态与动态参数相结合的方式，对诱导机组出现非稳定性的因素进行了研究；从压缩机内部流动的惯性和阻尼特征上，解释了该类机组的动态响应特征；发现了该类机组低压缸首先出现非稳定性，高压缸出现压力崩溃的现象．
This paper analyzes the surge characteristics of multistage centrifugal compressor. The factors that induce the instability of the generating unit are studied by means of the combination of steady state and dynamic parameters. The dynamic response characteristics of such units are explained from the inertia and damping characteristics of the internal flow of the compressor. The low pressure cylinder first appears instability, the pressure cylinder pressure collapse phenomenon.
