由于羅茨鼓風(fēng)機(jī)吸氣排氣過程中產(chǎn)生了強(qiáng)烈的噪聲,被人們稱為機(jī)械產(chǎn)品中的“聲老虎”，嚴(yán)重制約著生產(chǎn)的發(fā)展。若想在生產(chǎn)活動中正常使用羅茨鼓風(fēng)機(jī)，必須采取一定的降噪措施。

Due to the strong noise produced in the process of suction and exhaust of Roots blower, it is called "sound tiger" in mechanical products, which seriously restricts the development of production. If we want to use roots blower in production activities, we must take some noise reduction measures.

按照羅茨鼓風(fēng)機(jī)特點(diǎn)進(jìn)行分析，對鼓風(fēng)機(jī)噪聲的控制主要從吸聲和隔聲入手，采取下面的措施:建立隔聲罩、安裝消聲器、管道包扎、采用軟管和連接、采用隔聲門窗、粘貼吸聲材料等。

According to the characteristics of Roots blower, the noise control of blower mainly starts from sound absorption and sound insulation, and takes the following measures: establishing sound insulation cover, installing muffler, pipe binding, using hose and connection, using sound insulation doors and windows, pasting sound absorption materials, etc.

通過對羅茨鼓風(fēng)機(jī)噪聲嚴(yán)重的進(jìn)出口加裝消聲器，針對性的進(jìn)行吸聲和隔聲,這種方式簡單易行、對風(fēng)機(jī)的適應(yīng)性強(qiáng)，且不改變羅茨鼓風(fēng)機(jī)的結(jié)構(gòu)和精度，這種降噪方式對羅茨鼓風(fēng)機(jī)來說，是目前比較有效、應(yīng)用廣泛的一種降噪措施。

Through the installation of muffler at the inlet and outlet of Roots blower with serious noise, the sound absorption and sound insulation are targeted. This method is simple and easy to operate, has strong adaptability to the fan, and does not change the structure and precision of Roots blower. This noise reduction method is an effective and widely used noise reduction measure for Roots blower.

基于來源于對各類工業(yè)運(yùn)行的風(fēng)力機(jī)噪聲源的實(shí)際測試頻譜特征的數(shù)據(jù)，主要基于吸聲體設(shè)計(jì)和流體通道來確定譜范圍所需的降噪能力。同時(shí)采用較窄的矩形通道和較大的吸聲材料表面來增強(qiáng)吸聲效果。

Based on the data from the actual test spectrum characteristics of various industrial wind turbine noise sources, mainly based on the absorber design and fluid channel to determine the required noise reduction ability of the spectrum range. At the same time, a narrow rectangular channel and a large surface of sound absorption material are used to enhance the sound absorption effect.
