摘要
对离心式通风机噪声产生的机理进行了分析 ,并重点讨论离心式通风机在设计与改造中几种常用的降噪方法。可为离心风机降噪设计和降噪结构改造提供参考。
The pneumatic noise, the mechanical noise and the noise which is produced because gas couples with solid are the main parts of centrifugal fan noise. We analysed these noise mechanism in detail, and discussed several methods for reducing noise in designing and reforming centrifugal fan systematically. If we can use these methods suitably, the noise of centrifugal fan will be reduced effectively. At the same time, we provided references for the design of centrifugal fan for reducing noise, the reforming of centrifugal fan for reducing noise and the noise reduction of other model fans.
