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(fēng)管道不可能建造成筆直的。因此在建造的時(shí)候，我們可以盡量的削減風(fēng)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(shí)候沒有辦法避免比較大的轉(zhuǎn)角，這個(gè)時(shí)候可以采用軟接頭連接通風(fēng)管道，這個(gè)措施能夠有效的減少風(fēng)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(fēng)管道在建造和安裝的時(shí)候，需要結(jié)合實(shí)際的情況，提前控制好出風(fēng)與回風(fēng)的空間，避免出現(xiàn)空氣對(duì)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(fēng)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(fēng)管道的對(duì)應(yīng)位置，減少通風(fēng)管道的震動(dòng)。

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(fēng)管道加工幾點(diǎn)控制通風(fēng)管道噪音的方法，實(shí)際上這些方法對(duì)于的工作人員來講還是非常容易實(shí)現(xiàn)的，并且能夠帶來非常不錯(cuò)的效果，還能夠減少通風(fēng)管道的損耗延長(zhǎng)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.
