摘要(Abstract):

本文在试验结果的基础上分析了附加导叶的高度h和角度α对轴流风机性能的影响,结果表明,h=0.6~0.7b,α=20~30°时,附加导叶对风机性能有较大改善。
Based on test results, influence of attached guide vans highth h and angle α on axial fans performance have been analyzed. When h=0.6—0.7b, and α= 20—30°, performace of fans can be improved greatly by an attached guide vane.
