专注通风管道加工·排烟罩

In densely populated areas, ventilation ducts are generally required, mainly used for fresh air in spring and autumn, cooling in summer, and heating in winter. How much do you know about the specifications for air duct installation

安装前的准备工作：

Preparation before installation:

1.围护结构施工完毕，所有障碍物、杂物清理完毕，地面杂物清理完毕!

1. The construction of the enclosure structure is completed, all obstacles and debris are cleared, and the ground debris is cleared!

2.净化系统风管安装时，建筑物内部安装构件的地面已完成，墙体混凝土已找平。需要在室内无粉尘或防尘措施的情况下进行。

When installing the air duct of the purification system, the ground of the internal installation components of the building has been completed, and the wall concrete has been leveled. It needs to be carried out indoors without dust or dust prevention measures.

3.安装现场的辅助材料要齐全，施工技术人员应提供质量和技术指导。

3. The auxiliary materials on the installation site should be complete, and construction technicians should provide quality and technical guidance.

风管安装注意事项：

Precautions for air duct installation:

1.风管内严禁与其他管道交叉

1. It is strictly prohibited to cross with other pipelines inside the air duct

2.安装在易燃易爆环境中的风管应良好接地。穿过生活区或生产区的风管一定要安装严密，不得与设备风管接口。

2. Air ducts installed in flammable and explosive environments should be well grounded. Air ducts passing through living or production areas must be installed tightly and must not interface with equipment air ducts.

3.室外垂直风管的固定不得与避雷针或房屋防雷设施连接。

3. The fixation of outdoor vertical air duct shall not be connected with lightning rod or lightning protection facilities of the house.

4.风管安装需要符合下列技术规定：

4. The installation of air ducts needs to comply with the following technical regulations:

① 风管与通风设备及附件的连接配置不应减少其连接部位的连接管。

① The connection configuration between air ducts, ventilation equipment, and accessories should not reduce the number of connecting pipes at their connection points.

② 吊架不得设置在出风口、风阀、检查门和自动控制机构上，不得固定在法兰上，以免风管变形影响风管功能。

② Hangers shall not be installed on air vents, air valves, inspection doors, and automatic control mechanisms, nor shall they be fixed on flanges to prevent deformation of the air duct from affecting its function.

③ 吊架安装一定符合相应的安装规定。悬挂风管及部件应设置固定点，防止摆动，如固定支架、支架等。固定点的设置位置和数量应根据系统条件确定。

③ The installation of the hanger must comply with the corresponding installation regulations. Hanging air ducts and components should be equipped with fixed points to prevent swinging, such as fixed brackets, brackets, etc. The location and quantity of fixed points should be determined based on system conditions.

④ 法兰垫片和厚度根据输送空气的温度而不同。

④ The flange gasket and thickness vary depending on the temperature of the air being transported.

⑤ 风管及构件穿墙、穿屋面时，应设置防雨罩。当风管穿过屋面超过1.5m时，电缆应镀锌或使用钢丝绳。电缆不得固定在风管法兰或避雷针或防雷网络上。

⑤ When air ducts and components pass through walls or roofs, rain covers should be installed. When the air duct passes through the roof for more than 1.5m, the cable should be galvanized or steel wire rope should be used. The cable shall not be fixed on the air duct flange or lightning rod or lightning protection network.

⑥ 柔性短管的安装应具有适当的密封性，不得扭曲。柔性金属或非金属柔性风管长度不得超过2m，不得有死弯和塌陷。

⑥ The installation of flexible short pipes should have appropriate sealing and should not be twisted. The length of flexible metal or non-metallic flexible air ducts shall not exceed 2m, and there shall be no dead bends or collapses.

⑦ 保温风管支吊架应设置在保温层外，不得损坏保温层。

⑦ The insulation air duct support and hanger should be installed outside the insulation layer and should not damage the insulation layer.

事实上，无论是末端风管安装还是主机的安装，都需要经过的方案设计，由的安装团队进行，尽量避免出现不必要的麻烦，耽误施工进度。

In fact, whether it is the installation of terminal air ducts or the installation of hosts, it requires expert design and professional installation teams to avoid unnecessary trouble and delay the construction progress as much as possible.
