专注通风管道加工·排烟罩

风管主要应用在工业及建筑工程中，主要的作用是通风换气，降低室内温度，通风管道应用在很多行业，在食品加工、机械制造、药业制品、电子工业、购物中心都被广泛使用，但是通风管道怎么正确安装呢?但是如果你想要自己安装，就必须学会安装正确的流程步骤来进行工作。

Air ducts are mainly used in industrial and construction projects, with the main function of ventilation and reducing indoor temperature. Ventilation ducts are widely used in many industries, including food processing, machinery manufacturing, pharmaceutical products, electronics industry, and shopping centers. However, how can ventilation ducts be installed correctly? But if you want to install it yourself, you must learn the correct process steps to carry out the work.

风管组装：风管较短可以一次性在地面组装，风管较长可依据安装场地情况分段组装。组装时应尽量调整风道的中心度和水平度，避免风管扭曲或上下起波，左右摆龙，每段风道不宜超过10m。组装时，垫片应垫平，法兰螺栓应均匀拧紧，螺母帽均朝向同一方向。

Air duct assembly: Short air ducts can be assembled on the ground in one go, while longer air ducts can be assembled in sections according to the installation site conditions. During assembly, the centrality and levelness of the air duct should be adjusted as much as possible to avoid twisting or rippling of the air duct, and the length of each section of the air duct should not exceed 10m. During assembly, the gasket should be leveled, the flange bolts should be tightened evenly, and the nut caps should be facing in the same direction.

风管就位：先检查全部支架的水乎度、标高、牢固程度。风管就位一般使用直接和吊具两种方式。如果风管断面较小位置又很低的可采用人工就位方法，只需搭设简易脚手架即可。当风管断面较大且管段较长时，可采用滑轮、倒链、大绳等方法吊装。为了便于风道就位，一般多采用将风道吊在脚手架上，然后再将其抬放在风道支架上的方法。脚手架应沿其风道长度方向搭设，高度和位置应适合施工操作，吊装顺序应先干管后支、立管。

Air duct positioning: First, check the water level, elevation, and firmness of all supports. There are generally two methods for positioning air ducts: direct and lifting. If the cross-section of the air duct is small and the position is very low, manual positioning method can be used, and simple scaffolding can be erected. When the cross-section of the air duct is large and the pipe section is long, methods such as pulleys, chain blocks, and large ropes can be used for lifting. In order to facilitate the positioning of the air duct, it is generally used to hang the air duct on a scaffold and then lift it onto the air duct bracket. Scaffolding should be erected along the length direction of its air duct, and the height and position should be suitable for construction operations. The lifting sequence should start with dry pipes and then support and stand pipes.

风道调直：就位在支架上的风道，应拨正位置，调整风道横平竖直，然后再按图集要求固定。

Air duct straightening: The air duct placed on the bracket should be aligned, adjusted horizontally and vertically, and then fixed according to the requirements of the atlas.
