风机失速喘振特性及其预防措施

Discussion on Stall Surging Characteristic and its Prevention Measure

针对低、高压轴流送风机及多级轴流压缩机在低流量区域的失速喘振特性及其预防措施进行了分析。在并列压缩机假说下 ,对Day氏提出的一种求解多级轴流压缩机的级失速特性的模型进行了研讨。

The stall surging characteristic and its prevention measure are analysed with focus on low-pressure axial fan、 high-pressure axial fan and mutiple-stage axial compressor. Under the assuming of parallel comperessor, Day ,s predicting model of stage stall surging characteristic in mutiple-stage axial compressor are discussed.
