排烟罩在城市建设中非常关键，尤其是其安装质量也对气体交换有害，危及人们的工作效率。那么排烟罩的安装质量会受到各种因素的影响是怎样的内容呢？
Smoke exhaust hood is very important in urban construction, especially its installation quality is also harmful to gas exchange and endangers people's work efficiency. Then, the installation quality of smoke hood will be affected by various factors. What is the content?
做好项目施工前的准备工作。做好充分的准备是保证排烟罩安装质量的前提。提前准备制造净化处理用排烟罩时，无论是加工厂集中制造方式还是现场制造方式，都需要保证场所清洁密闭，有符合条件的照明和照明标准。此外，还需要对准备好的管道进行爱护，以尽量减少对环境的污染。
Make preparations before project construction. Adequate preparation is the premise to ensure the installation quality of smoke hood. When preparing the manufacturing of smoke hood for purification treatment in advance, whether it is centralized manufacturing in the processing plant or on-site manufacturing, it is necessary to ensure that the place is clean and closed, and there are qualified lighting and lighting standards. In addition, it is also necessary to take good care of the prepared pipelines to minimize environmental pollution.
材料的选择。材料的选择对排烟罩的施工质量也有很大的危害。一般来说，为了更好地保证排烟罩的净重，需要选择板厚较小的排烟罩，但除此之外，还要综合考虑排烟罩的规格和工作压力等级。从设计方案来看，特别注意的是，一个系统软件可以额外存储多种类型的排烟罩板厚度，以匹配不同的负压等级。
Selection of materials. The selection of materials also does great harm to the construction quality of smoke exhaust hood. Generally speaking, in order to better ensure the net weight of the smoke exhaust hood, the smoke exhaust hood with smaller plate thickness needs to be selected, but in addition, the specification and working pressure level of the smoke exhaust hood should be comprehensively considered. From the point of view of the design scheme, it is particularly noted that a system software can additionally store various types of smoke exhaust hood plate thickness to match different negative pressure levels.
排烟罩的水平连接。排烟罩的水平连接应注意一定的问题。这种接口方式可以说是保持风道长度的一种方式。它还具有提高抗弯刚度和保持排烟罩水平规格的作用。一般横向连接的方法是角铁弯套法兰。这种接口类型取决于壁厚，还取决于板墙结构的连接类型和加固方法。
Horizontal connection of smoke exhaust hood. Some problems should be paid attention to in the horizontal connection of smoke exhaust hood. This interface mode can be said to be a way to maintain the length of the air duct. It also has the function of improving the bending stiffness and maintaining the horizontal specification of the smoke exhaust hood. Generally, the method of transverse connection is angle iron bent sleeve flange. This type of interface depends on the wall thickness, as well as the connection type and reinforcement method of the plate wall structure.
排烟罩垂直接缝紧密连接。排烟罩的垂直接缝紧密连接方式可根据具体情况选择。在中压排烟罩和底压排烟罩中，经常使用纽扣式接头。对于矩形框架排烟罩，接头压槽的应用没有工作压力等级。因此，按钮式接头的应用可以节省逆向工艺流程。在这个阶段，大部分风道的垂直接缝通过纽扣式咬合紧密连接。对于立缝和密封立缝，可用螺栓、自攻螺钉、焊接、压花等方式进行紧固。
The vertical joints of the smoke exhaust hood are closely connected. The vertical joint tight connection mode of smoke exhaust hood can be selected according to specific conditions. Button joints are often used in medium pressure smoke exhaust hood and bottom pressure smoke exhaust hood. For rectangular frame smoke hood, the application of joint pressure groove has no working pressure grade. Therefore, the application of button joint can save the reverse process flow. At this stage, the vertical joints of most air ducts are closely connected through button bite. For vertical joints and sealing vertical joints, bolts, self tapping screws, welding, embossing and other methods can be used for fastening.
济南排烟罩的存放。预制排烟罩必须妥善保管，防止二次污染。支管可用塑料薄膜等橡胶密封条密封，然后排烟罩进行分类堆放。使用排烟罩前，注意进行彻底的清洁工作，确保板面耐腐蚀，干燥后不要扬尘。
Storage of smoke hood in Jinan. The prefabricated smoke exhaust hood must be kept properly to prevent secondary pollution. The branch pipe can be sealed with rubber sealing strips such as plastic film, and then the smoke exhaust hood is stacked by category. Before using the smoke exhaust hood, pay attention to thorough cleaning to ensure the corrosion resistance of the board surface, and do not raise dust after drying.
The installation quality of smoke hood will be affected by various factors. Of course, you need to know a variety of relevant content points in order to get a good return during the use of smoke hood. For more information, please visit www.1nightescorts.com Com consultation!
