摘要
说明了离心风机的主要噪声及产生机理,揭示了声压的计算方法以及声压与声功率的换算方式,同时也重点讲述了离心风机噪声的频谱特性。作为风机从业人员,应全面掌握噪声产生的机理和特性以及如何降低噪声污染。
This paper show the composition and production mechanism of centrifugal fan noise, and reveal calculation method of sound pressure and conversion of sound pressure and sound power. At the same time,frequency spectrum characteristics of centrifugal fan noise is also introduced in this paper. As engineer working on centrifugal fan,we should master centrifugal fan noise production mechanism and how to reduce noise.
