摘要
为解决通风机噪声污染问题,以2K-60-21-No24型主通风机噪声污染为例,研究分析噪声产生的机理特性,制定相应的综合治理措施。通过对噪声治理前后测试结果对比显示,采取的措施切实可行,得到了较好的降噪效果。
In order to solve the noise pollution problem of the ventilator, the noise pollution of the main fan of 2K-60-21- No24 is taken as an example to study the mechanism of noise generation, and the corresponding comprehensive measures are proposed. The comparison of the test results before and after the noise control shows that the proposed measures are feasible, and the better noise reduction effect is obtained.
