摘　　要：本文以压缩机试验台为载体,利用PCB声压传感器对单级离心压缩机扩压器位置声压信号进行测量,通过改变回流器叶片结构进行对比试验研究。经后期频谱分析及数据处理,得到旋转失速相关规律。为以后对压缩机扩大稳定运行范围设计提供试验依据。The experiment comparison of different return channel structure is carried on the test rig.The sound pressure sensor is used to measure the sound pressure signal in single stage centrifugal compressor diffuser.The rotating stall rules is found through the frequency spectrum analysis and after treatment.The conclusion is regard as the reference for enlarge the steady operation of compressor.
