摘　　要：利用自行建立的膨胀机性能试验台，不仅实测了滑片膨胀机在不同工况下的性能指标，还利用配置的动态压力测量系统，测得了表示其工作过程的指示图．经过对滑片膨胀机基本特性的研究，搞清了一些主要的运行参数对其性能的影响，为进一步设计和应用这种膨胀机奠定了基础．Experimental studies are carried out for investigating the fundamantal performances of the rotary vane expander with compressed air. A mathematical model is established for describing the working processes of the expander. With the experimental setup built during the study, the performances of the rotary vane expander are measured under various working conditions. Furthermore, the cellpressure variations are also recorded by a dynamic pressure measuring system. Based on the studies mentioned above, the effects of some important operating parameters on the expander performances are understood. And this is very helpful to design or operate this kind of expander.
