矿用气动通风机降噪技术研究

摘要

针对目前矿用气动通风机噪声较高的情况,分析了风机各部分噪声产生的原因和机理,对主要的噪声源即马达齿轮噪声和马达排气噪声,分别采用了不同的降噪技术,在实际应用中取得了不错的消声效果.%In view of great noise of the mine pneumatic fan,the paper analyzed the reasons and mechanism of noise producing from each part of the fan.In addition,different noise reduction technology were separately applied to main noise sources such as motor gear noise and motor exhaust noise,and good noise reduction effects was achieved in practical application.
