我相信很多人不知道什么是铁风管，这是一种通风风管，可以帮助气体的运输和循环。虽然这些人接触的机会较少，但它们为生活提供了很大的帮助。镀锌风管系统完成后，须进行相应的检查，以有效保证铁皮风管的质量和使用效果。让我们来看看实际的检查工作：
I believe many people don't know what iron air duct is. It is a kind of ventilation air duct, which can help the transportation and circulation of gas. Although these people have less access, they provide a lot of help for life. After the completion of galvanized air duct system, corresponding inspection must be carried out to effectively ensure the quality and use effect of iron sheet air duct. Let's take a look at the actual inspection work:
1.铁皮通风管道的强度应满足1.5倍工作压力下接缝处无裂纹；
1. The strength of iron sheet ventilation pipe shall meet the requirement that there is no crack at the joint under 1.5 times the working pressure;
2.采用漏光法监控系统风管严格水平：选择一定强度的安全灯源沿检查接口位置和接头缓慢移动，在另一侧进行观察检查，做好记录，发现接头泄漏需要密封；当选择泄漏法监控系统密封时，低压系统风管每10m接缝，漏光点不大于2处，且1OOm接缝平均值不大于16为合格；高压系统风管每10m接缝，漏光点不大于1，OOm接缝均值不大于8处为合格；
2. Use the light leakage method to monitor the strict level of the air duct of the system: select a certain intensity of safety light source to move slowly along the inspection interface position and joint, observe and check on the other side, make records, and find that the joint leakage needs to be sealed; When the leakage method monitoring system is selected for sealing, it is qualified that the light leakage point of the low-pressure system air duct is no more than 2 per 10m joint, and the average value of the 1OOm joint is no more than 16; For every 10m joint of the air duct of the high-pressure system, the light leakage point is not more than 1, and the average value of the oom joint is not more than 8;
3.系统漏风检测可以整体或分段进行。检测时，被测系统的所有开口应关闭，不得漏风。当漏风量超过设计和验收规范要求时，可以听.摸.观查.水或烟泄漏，找出漏风位置，做好标识；修好后，再次检测，直至合格。
3. The air leakage detection of the system can be carried out as a whole or in sections. During the test, all openings of the tested system shall be closed without air leakage. When the air leakage exceeds the requirements of design and acceptance specifications, you can listen Touch Observation If water or smoke leaks, find out the air leakage position and make a mark; After repair, test again until it is qualified.
The above is a detailed introduction about the ventilation ducts in Jinan. I hope it will help you If you have any questions, please contact us We will provide you with professional service http://www.jntfgd.com
