The main function of ventilation duct is to ensure the circulation of air and keep the indoor air clean. When a large amount of air flow passes through the ventilation duct, it may produce some noise. If it is in densely populated residential areas or prosperous commercial areas, the noise will have a great impact on people. So how can we avoid the noise generated by the ventilation duct during the installation of the ventilation duct? Let's explain it to you.

1.受到建筑結(jié)構(gòu)的影響，通風管道不可能建造成筆直的。因此在建造的時候，我們可以盡量的削減風道的轉(zhuǎn)角，避免氣流與管道壁產(chǎn)生較大的撞擊以及摩擦從而產(chǎn)生噪音。

1. Affected by the building structure, the ventilation duct cannot be built straight. Therefore, during construction, we can reduce the corner of the air duct as much as possible to avoid large impact and friction between the air flow and the pipe wall, resulting in noise.

2.有的時候沒有辦法避免比較大的轉(zhuǎn)角，這個時候可以采用軟接頭連接通風管道，這個措施能夠有效的減少風噪。

2. Sometimes there is no way to avoid large corners. At this time, soft joints can be used to connect the ventilation duct. This measure can effectively reduce wind noise.

3.通風管道在建造和安裝的時候，需要結(jié)合實際的情況，提前控制好出風與回風的空間，避免出現(xiàn)空氣對流，產(chǎn)生共振增加噪音。

3. During the construction and installation of the ventilation duct, it is necessary to control the air outlet and return space in advance in combination with the actual situation, so as to avoid air convection, resonance and noise.

4.通風管道在某些位置的噪音已經(jīng)影響到我們正常的生活或者生產(chǎn)，這是可以使用專門的避震器，安裝在通風管道的對應(yīng)位置，減少通風管道的震動。

4. The noise of the ventilation duct at some positions has affected our normal life or production. Therefore, special shock absorbers can be used and installed at the corresponding positions of the ventilation duct to reduce the vibration of the ventilation duct.

以上就是山東通風管道加工幾點控制通風管道噪音的方法，實際上這些方法對于的工作人員來講還是非常容易實現(xiàn)的，并且能夠帶來非常不錯的效果，還能夠減少通風管道的損耗延長使用壽命。

The above are the methods for Shandong ventilation duct processing to control the noise of ventilation duct. In fact, these methods are very easy to realize for professional staff, and can bring very good results, reduce the loss of ventilation duct and prolong the service life.
