摘要
介绍研究矿用轴流风机可直接反转反风课题的阶段性成果,通过对风机叶型拱度分别f为=0.022、0.033和0.0044的模型风机的性能测试和实验结果分析,确认叶型拱度是影响轴流风机反转反风量的最主要因素,完善了轴流风机直接反转反风理论。
This article presents the phase result of studying the mine use axial fan reversal ventilation project by direct contrarotation. Through the performance lest and the experimental resnlts analysis of the model fan with blade arching factors f=0.022, 0.033 and 0.004 respectively; it is confirmed that the blade arching factor is the most principal factor affecting the air flow of axial fan reversal ventilation by contrarotation. Thus the theory of reversal ventilation by direct contrarotation is perfected.
