摘要
针对矿用引风机等排粉机械叶片磨损较快的实际情况 ,从叶片受力以及空气动力学的角度 ,提出了变截面积防磨气垫叶片 。
In order to solving rapid detrition on coal mine fanner and these kinds of blowing dust machines,this paper proposed changing the section laminae with the air current on the basis of the principle of air dynamic and press.It protected effectually the fanner's laminae from rapid detrition.
