1. When processing and installing galvanized spiral air ducts for fans, vibration reduction devices should be installed according to design requirements or construction specifications.

2、风机.镀锌螺旋风管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 processing and installation of fans and galvanized spiral air ducts use hose connections. The hose at the fan suction port for galvanized spiral air duct processing and installation should be moderately tightened to avoid noise and vibration caused by loose soft connections and reduce the inlet and outlet area.

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. Produce galvanized spiral air ducts. Process and install galvanized spiral air ducts and connect them to components tightly, without air leakage, to avoid air leakage 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 vibration during the processing and installation of galvanized spiral air ducts, a fixed bracket is set at the connection between the ventilation fan and the air outlet at the turning point of each system's galvanized spiral air duct processing and installation.

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。

Galvanized spiral air duct processing and installation air leakage test: After the processing and installation of galvanized spiral air duct is completed, an air leakage test should be conducted. According to the specifications, the air leakage test for the processing and installation of galvanized spiral air ducts adopts a combination of light leakage method and quantitative air leakage test. The light leakage method is suitable for checking the tightness of the low-voltage system in the middle; The air leakage test is applicable to spot checks of medium voltage systems and comprehensive inspections of high voltage systems.

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。

Galvanized spiral air duct processing and installation leak detection method is a method that uses the strong transmittance of light to small holes to qualitatively detect the tightness of the galvanized spiral air duct processing and installation system. The test method is to use a voltage of no more than 36 V and a power of 100W on a certain length of galvanized spiral air duct during processing and installation in a dark environment. The bulb with a protective cover is slowly moved from one end of the spiral duct to the other end. If the light outside the spiral tube can be observed during the experiment, it indicates that there is a leakage point in the spiral tube, and the leakage point of the spiral tube should be repaired.
