因此要做好掌握多功能消声管的技术特性,熟悉施工图,了解土建和其它工种同本工种的相关情况,核实风管系统的标高,轴线、预留孔洞,预埋件等是否符合安装条件。备足安装用的各类辅助材料,准备好吊装机具和安装用的其它工具,对风管系统划线定位等工作。镀锌风管的安装需要哪些注意的地方?
Therefore, it is necessary to master the technical characteristics of the multi-functional silencing pipe, be familiar with the construction drawings, understand the relevant conditions of civil engineering and other types of work with this type of work, and verify whether the elevation, axis, reserved holes and embedded parts of the air duct system meet the installation conditions. Prepare all kinds of auxiliary materials for installation, prepare hoisting machines and other tools for installation, and mark and position the air duct system. What should be paid attention to in the installation of galvanized air duct?
风管的组对:将成品或预制好的风管运至安装地点,结合实际情况进行检查、复核,再按编号进行排列,风管系统的各部分尺寸和角度确确无误后,即开始风管组对工作。风管各管段之间的连接采用法兰连接,接口处要求严密不漏风。一次吊装风管的长度要根据建筑物的条件,风管的壁厚,吊装方法和吊装机具配备情况确定,组对好的风管可把两端的法兰做为基准点,以中间法兰为测点,拉线测量风管的连接是否平直,偏差大时要进行调整。
Assembly of air duct: the finished or prefabricated air duct shall be transported to the installation site, checked and rechecked in combination with the actual situation, and then arranged according to the number. After the size and angle of each part of the air duct system are correct, the assembly of air duct shall be started. The connection between each pipe section of the air duct adopts flange connection, and the interface is required to be tight without air leakage. The length of the air duct for one-time hoisting shall be determined according to the conditions of the building, the wall thickness of the air duct, the hoisting method and the allocation of hoisting machines and tools. For the assembled air duct, the flanges at both ends can be used as the reference point, and the middle flange can be used as the measuring point. Draw a line to measure whether the connection of the air duct is straight. If the deviation is large, it shall be adjusted.
不锈钢板的强度要比普通钢板高,用不锈钢板咬口前,要作成形试验,避免使设备负荷作业,形成过度磨损或机械事端。由于铝板塑性差,咬口成形时容易开裂,施工前也要作成形试验,同时,因铝板缺乏弹性,铝板风管不能进行按扣式咬口。镀锌风管的锌镀层经钝化处理、染色或涂覆护光剂后,能明显提高其防护性和装饰性。
The strength of stainless steel plate is higher than that of ordinary steel plate. Before biting with stainless steel plate, the forming test shall be conducted to avoid excessive wear or mechanical trouble caused by equipment load operation. Due to the poor plasticity of the aluminum plate, the undercut is easy to crack during forming, and the forming test shall also be carried out before construction. At the same time, due to the lack of elasticity of the aluminum plate, the aluminum plate air duct cannot carry out snap type undercut. The zinc coating of galvanized air duct can significantly improve its protection and decoration after passivation, dyeing or coating with light protection agent.
