对于风管系统严密性检验的方法有两种：低压系统的风管在制作、安装工艺得到保证的前提下，可采用漏光法检验中、高压系统风管应采用漏风量测试方法。下面济南风管加工厂为您进行分析：

There are two methods for inspecting the tightness of the air duct system: under the premise of ensuring the production and installation process of the low pressure system air duct, the light leakage method can be used for inspection. The medium and high pressure system air ducts should use the air leakage test method. Below, Jinan Air Pipe Processing Factory will analyze for you:

1、风管系统安装完毕后，应按系统类别进行严密性检验。

1. After the installation of the air duct system is completed, the tightness inspection should be carried out according to the system category.

2、检测应采用具有一定强度的光源。手持移动光源可采用不低于100W带保护罩的低压照明灯，或其他低压光源。

2. The detection should use a safe light source with a certain intensity. Handheld mobile light sources can use low-voltage lighting lamps with protective covers of no less than 100W, or other low-voltage light sources.

3、系统风管漏光检测时，光源可置于风管内侧或外侧，但其相对侧应为暗黑环境。检测光源应沿着被检测接口部位与接缝做缓慢移动，在另一侧进行观察，当发现有光线射出，则说明查出明显漏风处，并应做好记录。

3. When detecting air duct leakage in the system, the light source can be placed on the inner or outer side of the air duct, but its opposite side should be in a dark environment. The detection light source should move slowly along the tested interface and seam, and observe on the other side. If light is found to be emitted, it indicates that a significant air leakage has been identified and records should be kept.

4、对系统风管的检测，宜采用分段检测、汇总分析的方法。在严格安装质量管理的基础上，系统风管的检测以总管和干管为主。

4. The detection of system air ducts should be carried out using segmented detection and summary analysis methods. On the basis of strict installation quality management, the detection of system air ducts is mainly focused on the main and main pipes.

当采用漏光法检测系统的严密性时，低压系统风管以每10m接缝，漏光点不大于2处，且100m接缝平均不大于16处为合格中压系统风管每10m接缝，漏光点不大于1处，且100m接缝平均不大于8处为合格。

When using the light leakage method to detect the tightness of the system, the low-pressure system air duct is qualified if there are no more than 2 light leakage points per 10m of joints, and the average number of 100 m joints is no more than 16. The medium pressure system air duct is qualified if there are no more than 1 light leakage point per 10m of joints, and the average number of 100 m joints is no more than 8.
