Pipeline and construction pipeline should pay attention to the operation specification in the construction. The use of ventilation pipeline in family buildings also needs to meet certain construction standards. For the construction process of air duct, the type of air duct is generally selected according to the design level. At the same time, in the design, it is necessary to refer to the construction environment and the difficulty of the role, and estimate the layout design of the ventilation pipeline.

因为风管资料是镀锌板或者是金属资料，在施工时要严厉按照施工验收标准选择钢板厚度和施工工艺，比如风管制造偏差、平直度、风管加固、支吊架选择及制造装置等等。到了施工阶段，出风口尽量不要靠近设备。

Because the air duct information is galvanized sheet or metal information, the steel plate thickness and construction technology should be strictly selected according to the construction acceptance standard, such as the air duct manufacturing deviation, straightness, air duct reinforcement, support selection and manufacturing device, etc. At the construction stage, the air outlet should not be close to the equipment as far as possible.

假如可以添加弯头数目也可以下降噪音，风口加装过滤网，噪音操控效果也很好。 风机的声响。处理办法我们通常可装消声器处理风管中风的冲突声。通常在设计阶段就要思考噪声的问题，设计操控好管内风速，防止风声啸叫，以下是一些经历。

If the number of elbows can be added, the noise can also be reduced. If the air outlet is equipped with a filter, the noise control effect is also very good. The sound of the fan. How to deal with it we can usually install a muffler to deal with the conflicting sound of the wind in the air duct. Usually in the design stage, we need to consider the problem of noise, design and control the wind speed in the pipe to prevent the wind from whistling. Here are some experiences.

1、螺旋风管风道转角尽量削减。

1. The angle of spiral duct should be reduced as much as possible.

2、软接头装置标准，防止软接帆布松垮发生风阻而形成风噪。

2. The standard of flexible joint device can prevent wind resistance and wind noise caused by loose canvas.

3、螺旋风管风机叶轮体系动平衡校调合理正常正负不大于5丝的起伏。

3. The dynamic balance adjustment of spiral duct fan impeller system is reasonable, and the fluctuation of positive and negative is no more than 5 threads.

4、操控出风、回风间隔，防止空气对流时自激表象和小循环空间。

4. Control the air outlet and return air interval to prevent the self-excited appearance and small circulation space during air convection.

5、悬挂选用顺便弹簧避震专职的连接器，减轻运转时因扭力发生的跳动或共频。

5. The suspension adopts the spring shock absorber connector to reduce the runout or common frequency caused by torsion during operation.

通过设计能够很好的规划出管道的界限，这样也能够为其他的系统提供可靠的保障。而且设计布局更加合理，也能够增加建筑的温馨指数，可谓是一劳多益

The pipeline boundary can be well planned through the design, which can also provide reliable guarantee for other systems. Moreover, the design layout is more reasonable, which can also increase the warmth index of the building
