摘要
研制了一套光电式内部流场测试系统，对旋转风机叶轮叶片表面上的静压力分布进行了测试，并将测试结果与机械式压力转换器的结果相比较，证明了本系统的可行性和优越性。同时提出了对该系统的改进措施。
A set of optiˉelectronic pressure measuring and transfering system is desinged,by means of which,the static pressure distribution on the blade of a rotating centrifugul fan has been measured.Comparison and discussion of the measuring results by different pressure transfer devices(PTD) are made in the paper. The experiment shows the availability and superiority of the opti electronic measuring system. Meanwhile,some improvement proposals are also presented.
