摘　　要：针对多级离心式压缩机停车工况波动大、易喘振的问题,使用HYSYS建立动态仿真模型,研究各种情况下多级离心式压缩机停车的具体机组响应,并研究了防喘振阀Cv值和行程时间对多级离心式压缩机系统喘振的影响,为多级离心式压缩机防喘振阀选型提供理论支持。With respect to the large vibration and surging happened on multistage centrifugal compressor at the time of shutting down,we used the software HYSYS to build up dynamic simulation model,studied the responses of the compressor shutdown under different cases,and researched the influence of Cv value of anti-surging valve and its stroke time on the surge happened in the compressor system,which will provide the theoretical support on anti-surging valve model selection in multi-stage centrifugal compressor.
