| 摘 要： | 在一离心压缩系统喘振实验台上，通过系统各位置及沿叶轮出口圆周上压力波动进行的动态测量，对进入及退出瑞振时的瞬态特性进行了实验观察．实验发现系统的喘振首先发生在储气容腔内，并由下游向上游发展，在此过程中喘振幅度从容腔至进口管呈减小的趋势，且发生时间也逐渐落后．此外，还对喘振的形成和退出过程及其相应特性也进行了观察．

| Abstract: | The surge emerging and removing processes in a low speed centrifugal compression system are observed by measurement with 12 high response pressure transducers from inlet pipe, periphery of impeller, outlet pipe, to plenum. The pressure traces exhibit that the emergence of surge firstly occurs in plenum, and develops to inlet components in a certain time delay The results also show a large decrease in amplitude of pressure fluctuation fromplenum to inlet pipe. The selfrexcitation properties of surge emerging and removing surge are also investigated. |
