摘　　要：对扩压器进口不同安装角和进口导叶不同预旋角匹配下离心压缩机的性能进行了实验研究.研究表明:扩压器进口安装角最小值为7°时,压缩机性能对进口导叶预旋角不敏感;采用不同的扩压器进口安装角和不同进口导叶预旋角匹配调节时,压缩机所能达到的最高效率为86.0%,比单独调节进口导叶预旋角或扩压器进口安装角所能达到的效率高2%.效率提高的潜能可通过自由选择匹配的方式来加以实现.The performance of the centrifugal compressor at different diffuser stagger angles and different inlet guide vane （IGV） prewhirl angles are measured. The investigation shows the performance gets quite insensitive to the prewhirl angle of IGV as the stagger angle of diffuser vane is reduced to the minimum 7°; the combination of these two stators enables to greatly improve the compressor efficiency over the entire operating rage, the maximum efficiency with the combined adjustment reaches 86.0%, higher than that in alone adjustment of IGV or diffuser vanes by 2%. The potential efficiency can be exploited via freely selectable mode of matched adjustment.
