摘要
介绍了 BKJ型子午轴流局部通风机减小动叶与机壳间隙和增大动叶与后置导叶轴向间距对其气动噪声影响的试验结果 。
The experiment results of reducing air dynamic noise of mining axial local typed BKJ are showed by reducing the gap between the tip of rotor and case and increasing the distance between rotor and state.The basis for designing the lower noise fans is provided.
