答：如果想解决风机噪音大的问题，需要根据风机的用途与安装环境，排查噪音大的原因！根据其不同的噪音来源解决噪音问题！由于我们厂主要是生产销售罗茨风机、喷泉曝气机、环形风机的厂家！其他的风机设备我们还不是很了解，今天我就以我们生产的风机设备噪音大的解决方法分享给大家！

罗茨风机噪音大的处理方法

       罗茨风机的噪音来源主要是摩擦音与振动音！罗茨风机主机噪音的解决方法分别是在风机进出口加装消音器，或单独为风机加装一个隔音罩隔音房！如果风机噪音不大，但是管道振动高产生了噪音困扰的！可以在风机消音器与管道之间加装一个弹性软接头！从而减少罗茨风机的震动传送到管道！

环形风机噪音大的处理方法

环形风机的噪音来源一般具有以下几种情况：

1. 因叶片回转而产生噪音；

2. 涡流产生噪音；

3. 风道乱流而产生噪音；

4. 风管外壳产生共振而发生噪音；
   

5. 鼓风机以外引起的噪音；
   大家可以根据自己的环形风机的实际运转情况，判断噪音来源，从而实施不同的解决方法！切勿随意改动风机！同时也可以联系自己风机的购买渠道帮助解决噪音问题！
   
   

   　　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!
