1、做好施工前的准备工作
1. Do a good job in preparation before construction.
俗话说“磨刀不误砍柴工”,充分的准备工作是确保风管安装质量的前提。在准备净化风管的制作时,无论是采取工厂集中制作还是现场制作方式,都必须保证场地的洁净和封闭,并拥有符合条件的采光和照明条件。除此外,还要对制作好的方管进行看管,尽量避免污染。
As the saying goes, "sharpening the chopper is not a mistake", adequate preparation is the prerequisite for ensuring the quality of the installation of the wind pipe. In preparation for the production of purifying ducts, whether in factory centralized production or on-site production, must ensure that the site is clean and closed, and have qualified lighting and lighting conditions. Besides, the square tubes should be carefully monitored to avoid pollution.
2、风管材质的选择
2. Selection of duct material
风管材质的选择,对风管的施工质量也有很大的影响。一般而言为了保证风管的重量,需采用小板厚的风管,但除此外还需要综合考虑风管的尺寸和压力级别。从设计角度来看,值得注意的是一个系统可以同时存在几种对应于不同静压级别的风管板厚。
The selection of duct material has great influence on the construction quality of the duct. Generally speaking, in order to ensure the weight of the duct, the minimum thickness of the duct is required, but in addition to the need to consider the size of the duct and pressure level. From the design point of view, it is noteworthy that there are several kinds of duct thickness corresponding to different static pressure levels in a system.
3、风管的横向连接
3. Transverse connection of wind pipes
风管的横向连接有一定讲究,这种连接方式可以说是是延续风管长度的一种手段,还具备增强刚度及保持风管精确地横向尺寸的作用。通常横向连接的方式是角钢法兰连接,这种连接方式取决于壁厚,更取决于连接种类及板壁加固方式。
The transverse connection of the air duct is particular, which can be said to be a means of extending the length of the air duct. It also has the function of enhancing the stiffness and maintaining the accurate transverse dimension of the air duct. Generally, the way of lateral connection is angle steel flange connection, which depends on the thickness of the wall, more depends on the type of connection and plate wall reinforcement.

4、风管的纵向缝接合
4. Longitudinal joint of wind pipes.
风管的纵向缝接合方式可以根据实际情况,选择对应的方式。在中、低压风管中常常使用扣式咬口连接,对于矩形风管,联合咬口使用无任何压力级别,因此使用扣式咬口可以节省一道翻边工序,目前大多数的风管纵向缝接合都采用了扣式咬口。对于立缝和封盖式立缝可以使用铆钉、自攻螺丝、点焊、压凸凹痕等方法紧固。
The longitudinal joints of wind pipes can be selected according to the actual situation. In the middle and low pressure air ducts, the buckle bite is often used. For rectangular air ducts, the joint bite is used without any pressure level. Therefore, the use of the buckle bite can save a flanging process. At present, most of the longitudinal seam joints of the air duct are used buckle bite. For vertical seams and capped vertical seams, rivets, tapping screws, spot welding, indentation and other methods can be used to fasten.
5、风管的存放
5. Storage of air duct
预制好的风管,是必须要做好存放工作,以免受到二次污染。可将管口用塑料布等密封材料封住,然后将风管分门别类堆放好。在使用风管前,要注意进行彻底的清洗工作,确定板材表面无腐蚀,干燥后不吸尘。
The prefabricated good duct must be stored well so as not to be contaminated by the two pollution. The pipe can be sealed with plastic cloth and other sealing materials, and then the air pipes can be stacked in different categories. Before using the air duct, we should pay attention to thorough cleaning to ensure that the surface of the plate is non-corrosive, no dust after drying.
