1、通风管道加工安装时，根据设计要求或施工规范要求，设置减振装置。

1. During the processing and installation of ventilation pipes, vibration damping devices shall be set according to the design requirements or construction specifications.

2、通风管道加工安装采用软管连接，风机吸入口的软管镀锌螺旋风管加工安装应适度拧紧，避免因软连接过松而造成噪音和振动，减少进出口面积。

2. The ventilation duct shall be processed and installed with hose connection. The galvanized spiral air duct at the fan inlet shall be properly tightened to avoid noise and vibration caused by loose soft connection and reduce the area of inlet and outlet.

3、制作镀锌螺旋风管、镀锌螺旋风管加工安装及与部件连接，连接紧密，无漏气现象，避免漏气噪声。

3. The galvanized spiral air duct shall be manufactured, processed, installed and connected with components, and shall be tightly connected without air leakage and noise.

4、为了防止镀锌螺旋风管加工安装的振动，在每个系统镀锌螺旋风管加工安装的转弯处、固定支架设置在通风机与风口的连接处。

4. In order to prevent the vibration of the processing and installation of the galvanized spiral air duct, the turning and fixing bracket of the processing and installation of the galvanized spiral air duct of each system are set at the connection of the fan and the air outlet.

镀锌螺旋风管加工安装漏风试验：镀锌螺旋风管加工安装完毕后，应进行漏风试验。根据规范，镀锌螺旋风管加工安装的漏风试验采用漏光法和漏风试验定量试验相结合，漏光法适用于中间.检查低压系统的严密性；漏风试验适用于中压系统的抽检和高压系统的检测。

Air leakage test for processing and installation of galvanized spiral air duct: after processing and installation of galvanized spiral air duct, air leakage test shall be conducted. According to the specification, the air leakage test for the processing and installation of galvanized spiral air duct adopts the combination of the light leakage method and the quantitative test of the air leakage test. The light leakage method is applicable to the middle. Check the tightness of the low-voltage system; The air leakage test is applicable to the sampling inspection of the medium-voltage system and the overall inspection of the high-voltage system.

镀锌螺旋风管加工安装漏光法检测漏光法检测是一种利用光线对小孔的强透视力来定性检测系统镀锌螺旋风管加工安装严密性的方法。试验方法是在一定长度的镀锌螺旋风管加工安装上，在黑暗的环境下，在镀锌螺旋风管加工安装中使用不超过36的电压V，功率在100W上述带有保护罩的灯泡从螺旋管的一端缓慢移动到另一端。如果在试验过程中可以观察到螺旋管外的光线，则表明螺旋管有泄漏点，并修复螺旋管的泄漏点。

Light leakage method for processing and installation of galvanized spiral air duct The light leakage method is a method to qualitatively detect the tightness of the processing and installation of galvanized spiral air duct of the system by using the strong penetration of light to the small hole. The test method is to use a voltage of not more than 36 V and a power of 100W in the processing and installation of galvanized spiral air duct with a certain length, and in the dark environment, the bulb with protective cover moves slowly from one end of the spiral duct to the other end. If the light outside the spiral tube can be observed during the test, it indicates that the spiral tube has a leakage point, and repair the leakage point of the spiral tube.

系统镀锌螺旋风管加工安装漏光检测采用分段检测，总结分析方法：被测系统镀锌螺旋风管加工安装不允许多条缝明显漏光，低压系统镀锌螺旋风管加工安装每10米接缝不超过2个漏光点，100米接缝平均不超过16个；中压系统镀锌螺旋风管加工安装每10个接缝，漏光点不超过1个，100米接缝平均不超过8个。

The light leakage detection for the processing and installation of the galvanized spiral air duct of the system adopts sectional detection, and the summary and analysis method: the processing and installation of the galvanized spiral air duct of the system under test shall not allow multiple seams to have obvious light leakage, and the processing and installation of the galvanized spiral air duct of the low-voltage system shall not exceed 2 light leakage points every 10 meters, and the average of the 100 meters of joints shall not exceed 16; For the processing and installation of galvanized spiral air duct of medium pressure system, there shall be no more than 1 light leakage point for every 10 joints, and no more than 8 joints for 100 meters on average.
