摘要
全面地分析和研究了高风压大流量风机的强噪声问题。对噪声源的部位进行了局部改造和新颖的设计。同时根据风机和风道的噪声频谱进行了吸声隔声室和吸声隔声罩的设计。经改造安装后测量得知 。
The problems of strong noise for fan with high pressure and large capacity are comprehensively analyzed & researched.Local improvement & novel design are carried out on the position of noise supply. At the same time, design of acoustical room & enclosure is carried out according to the noise spectrum of fan & air passage. Obvious results of noise reducing & energy saving are obtained by measurement after transforming & mounting.
