通风管道的安装质量受哪些因素的影响呢?

发布人:   发布时间:2020-07-08 15:58:02

  通风管道在大家现在的城市建设中非常重要,特别是安装质量问题,直接影响了空气的交换,影响了人们的正常工作活动,效率,那么它的安装质量受到哪些因素的影响呢?

  Ventilation duct is very important in our urban construction, especially the installation quality problem, which directly affects the air exchange, affects people's normal work activities and efficiency, so what factors affect its installation quality?

  1、施工前的准备工作

  1. Preparation before construction

  俗话说,“磨刀不误砍柴”,充分的说明准备是保证风管安装质量的前提。准备清洁管道的制作,无论采用工厂集中制作还是现场制作方式,都要保证场所的清洁和关闭,具有符合条件的采光和照明条件。另外,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 knife does not cut firewood by mistake". Sufficient preparation is the premise to ensure the installation quality of air duct. Preparation for the production of clean pipes, whether factory centralized production or on-site production, should ensure that the site is clean and closed, with qualified lighting and lighting conditions. In addition, it is necessary to take care of the square tube to avoid pollution.

  2、风管材质的选择

  2. Selection of duct material

  通风管道材质的选择对管道的施工质量也有很大影响。一般来说,为了保证管道的重量,需要较小板厚的管道,但需要综合考虑管道的尺寸和压力水平。从设计角度来看,值得注意的是,一个系统可以同时具有对应于不同静态压力水平的几个管道厚度。

  The selection of ventilation pipe material also has a great impact on the construction quality of the pipeline. Generally speaking, in order to ensure the weight of the pipe, the pipe with smaller plate thickness is needed, but the pipe size and pressure level should be considered comprehensively. From a design point of view, it is worth noting that a system can have several pipe thicknesses corresponding to different static pressure levels at the same time.

  3、风管的横向连接

  3. Transverse connection of air duct

  风管的横向连接有一定的应力。这种连接方法可以说是延长空气导管长度的手段,并且还具有增强刚性和保持空气导管横向尺寸的功能通常,横向连接方式是角钢法兰连接。这种连接模式取决于壁厚,也取决于连接类型和板墙加固模式。

  The transverse connection of air duct has certain stress. This connection method can be said to be a means to extend the length of the air duct, and also has the function of enhancing the rigidity and maintaining the transverse dimension of the air duct. Generally, the transverse connection mode is angle steel flange connection. The connection mode depends on the wall thickness, the connection type and the reinforcement mode of the panel wall.

  4、风管的纵向缝接合

  4. Longitudinal joint of air duct

  风管的纵接缝接合方式可根据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 joint mode of longitudinal joint of air duct can be selected according to the situation. In the medium and low pressure air duct, the button type bite connection is often used. For rectangular air duct, the joint bite has no pressure level, so the use of button type bite can save a flanging process. At present, most of the longitudinal seam joints of air duct adopt the button type bite. Rivets, self tapping screws, spot welding and dent pressing can be used to fasten the vertical seam and cover type vertical seam.

  5、风管的存放

  5. Storage of air duct

  预制好的风管,需要做好存放工作,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。使用管道前,请注意清洗作业,确认板材表面没有腐蚀,干燥后不进行清扫。

  The prefabricated air duct needs to be stored well to avoid secondary pollution. The pipe orifice can be sealed with plastic cloth and other sealing materials, and then the air duct can be stacked in different categories. Before using the pipeline, please pay attention to the cleaning operation, make sure that the surface of the plate is not corroded, and do not clean after drying.
