答：如果想解決風機噪音大的問題，需要根據風機的用途與安裝環境，排查噪音大的原因！根據其不同的噪音來源解決噪音問題！由于我們廠主要是生產銷售羅茨風機、噴泉曝氣機、環形風機的廠家！其他的風機設備我們還不是很了解，今天我就以我們生產的風機設備噪音大的解決方法分享給大家！

羅茨風機噪音大的處理方法

       羅茨風機的噪音來源主要是摩擦音與振動音！羅茨風機主機噪音的解決方法分別是在風機進出口加裝消音器，或單獨為風機加裝一個隔音罩隔音房！如果風機噪音不大，但是管道振動高產生了噪音困擾的！可以在風機消音器與管道之間加裝一個彈性軟接頭！從而減少羅茨風機的震動傳送到管道！

環形風機噪音大的處理方法

環形風機的噪音來源一般具有以下幾種情況：

1. 因葉片回轉而產生噪音；

2. 渦流產生噪音；

3. 風道亂流而產生噪音；

4. 風管外殼產生共振而發生噪音；
   

5. 鼓風機以外引起的噪音；
   大家可以根據自己的環形風機的實際運轉情況，判斷噪音來源，從而實施不同的解決方法！切勿隨意改動風機！同時也可以聯系自己風機的購買渠道幫助解決噪音問題！
   
   

   　　Answer: if you want to solve the problem of high fan noise, you need to check the causes of high noise according to the purpose and installation environment of the fan! Solve the noise problem according to its different noise sources! Because our factory mainly produces and sells roots blower, fountain aerator and annular blower! We don't know much about other fan equipment. Today, I will share with you the solutions to the high noise of our fan equipment!

   　　Treatment of the noise of Roots blower

   　　The noise source of Roots blower is mainly friction sound and vibration sound! The solution to the noise of Roots blower is to install a silencer at the inlet and outlet of the blower, or to install a sound proof cover and sound proof room separately for the blower! If the fan noise is not high, but the pipe vibration is high, it will cause noise problems! A flexible joint can be installed between the fan silencer and the pipe! So as to reduce the vibration of Roots blower transmitted to the pipeline!

   　　How to deal with loud fan noise

   　　Treatment method for high noise of annular fan

   　　The noise sources of annular fan generally include the following situations:

   　　Noise due to blade rotation;

   　　Noise generated by eddy current;

   　　Noise caused by turbulent flow in air duct;

   　　The air duct shell produces resonance and noise;

   　　Noise outside the blower;

   　　You can judge the noise source according to the actual operation of your annular fan, so as to implement different solutions! Do not change the fan at will! At the same time, you can also contact your own fan purchase channel to help solve the noise problem!
