摘　　要：以某型轴流式通风机为研究对象,对一级导叶不同结构特征对通风性能的影响进行研究,结果表明:风机采用复合式导叶片时其工作性能要优于单一长度结构的导叶片,在一级导叶片中,其工作时的周向、轴向和导叶片的长度均会对风机通风性能造成影响,当导叶片的长度为320 mm时风机具有最优的工作性能。The influence of different structure characteristics of the first-stage guide vane on ventilation performance was studied.The results showed that the performance of the fan was better than that of the single-length guide vane when the fan adopted the compound guide vane.In the first-stage guide vane,the circumferential direction,axial direction and the length of the guide vane would affect the ventilation performance of the fan.When the length of the guide vane was 320 mm,the fan had the best performance.
