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.受到建筑结构的影响，通风91短视频三级片不可能建造成笔直的。因此在建造的时候，91短视频版高清在线观看免费可以尽量的削减风道的转角，避免气流与91短视频三级片壁产生较大的撞击以及摩擦从而产生噪音。

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.有的时候没有办法避免比较大的转角，这个时候可以采用软接头连接通风91短视频三级片，这个措施能够有效的减少风噪。

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.通风91短视频三级片在建造和安装的时候，需要结合实际的情况，提前控制好出风与回风的空间，避免出现空气对流，产生共振增加噪音。

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.通风91短视频三级片在某些位置的噪音已经影响到91短视频版高清在线观看免费正常的生活或者生产，这是可以使用专门的避震器，安装在通风91短视频三级片的对应位置，减少通风91短视频三级片的震动。

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.

以上就是山东通风91短视频三级片加工几点控制通风91短视频三级片噪音的方法，实际上这些方法对于的工作人员来讲还是非常容易实现的，并且能够带来非常不错的效果，还能够减少通风91短视频三级片的损耗延长使用寿命。

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.
