摘要
矿用贯流风机噪声的主要成分是旋转噪声和涡流噪声。它的形成与蜗舌的存在有直接的联系,底板间隙和蜗舌间隙选取合理与否是影响贯流风机噪声大小的主要原因,所以合理优化底板间隙和蜗舌间隙可以消除风机刺耳的啸叫声。
The tubular cross flow fan is the main component of rotation noise and worm flow noise. The formation and the snail＇s tongue there is a direct link in the design, pair of straight-tongue and tilttongue comparison was informed that the use of the tih-tongue turbine fan noise substantially reduced, fan the piercing whistle sounds has disappeared.
