高速离心压缩机组失稳状态分析及对策

UNSTABILITY SITOATION ANALYSIS OF HIGH-SPEED CENTRIFUGAL COMPRESSOR MACHINE TRAIN AND ITS COUNTERMEASURE

高速离心压缩机组启、停车过程失稳将产生强烈振动,极易造成动、静部件损伤。文章对离心压缩机组启、停车过程失稳特性进行分析,找到了机组失稳的原因及控制对策。

With the unstability of high-speed centrifugal compressor machine train during starts up and shuts down,the judder vibration is generated, which damages to moving and static components easily. This article analyzes the unstability feature of centrifugal compressor machine train during start-up and shut-dawn and finds out the reason of the machine train unstability and control countermeasure.
