摘　　要：通过对一台矿用对旋式通风机在非额定工况上叶栅的流场分析,得到该通风机在一定角度下前后级叶栅的气流参数及负荷的分布情况,并揭示造成两级负荷不一致的内在原因,然后又对一台对旋式通风机模型机的性能试验,得到了两级叶栅在一定角度下负荷的变化规律,试验结果与理论分析数据基本吻合。根据理论分析及试验结果,定性地给出了达到两级负荷匹配时叶片安装角的变化规律。Through the flow cascade analysis of one mine counter-rotating fan under non-rated condition, gains the distribution situation of before and after cascade flow parameters and load in certain angle, and reveals the reasons leading to mismatching of two inconsistent load . Through the performance test on a counter-rotating fan model, gets the loading change regulation of two stage cascades in a certain angle. And the test results show good agreement with the theoretical analysis. According to the theoretical analysis and the experimental results, reveals the change regulation of the blade installation angle when reaching two-stage load matching.
