        哪些因素影响通风管道的安装?
        来源:m.inight.cn 2019-02-28 11:45:13
        通风管道在城市建筑中非常的重要,尤其是它的安装质量更是影响到空气的交换,影响人们的正常的“活动”,影响人们的工作效率。今天通风管道公司就为大家介绍哪些方面的因素能够影响到通风管道的安装质量。
        Ventilation pipeline is very important in urban buildings, especially its installation quality affects air exchange, affects people's normal "activities" and affects people's work efficiency. Today, the Ventilation Pipeline Company will introduce to you what factors can affect the installation quality of the ventilation pipes.
        1、做好施工前的准备工作
        1. Preparing for 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, "no mistake in cutting firewood by sharpening knives", adequate preparation is the premise to ensure the installation quality of air ducts. When preparing for the production of purified air ducts, whether centralized production in factories or on-site production, it is necessary to ensure that the site is clean and closed, and has the lighting and lighting conditions that meet the requirements. In addition, we should also take care of the square tubes made to avoid pollution as far as possible.
        2、风管材质的选择
        2. Selection of Air Pipe 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,需采用最小板厚的风管,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 air duct material also has a great influence on the construction quality of air duct. Generally speaking, in order to ensure the weight of the duct, the minimum thickness of the duct is needed, but in addition, the size and pressure level of the duct need to be considered comprehensively. From the design point of view, it is worth noting that there are several duct sheet thicknesses corresponding to different static pressure levels in a system at the same time.

        3、风管的横向连接
        3. Horizontal connection of air duct
        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 horizontal connection of air duct is particular. It can be said that this connection is a means to extend the length of air duct. It also has the function of enhancing stiffness and keeping accurate lateral dimension of air duct. Usually the way of lateral connection is angle steel flange connection, which depends on the thickness of the wall, but also depends on the type of connection and the way of plate wall reinforcement.
        4、风管的纵向缝接合
        4. Longitudinal seam joint of air duct
        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 joint mode of air duct can be selected according to the actual situation. Button bite connection is often used in middle and low pressure air ducts. For rectangular air ducts, there is no pressure level for joint bite. Therefore, using buckle bite can save a flanging process. At present, buckle bite is used in most longitudinal seam joints of air ducts. Rivets, tapping screw, spot welding and indentation can be used to fasten the vertical seam and capping vertical seam.
        5、风管的存放
        5. Storage of air ducts
        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。
        Prefabricated air ducts must be stored well to avoid secondary pollution. The nozzle can be sealed with plastic cloth and other sealing materials, and then the air ducts can be stacked in different categories. Before using the air duct, we should pay attention to thorough cleaning work to ensure that there is no corrosion on the surface of the sheet and no dust absorption after drying.
