①安装风扇时，请根据设计要求或施工规范安装减振装置。

① When installing the fan, please install the vibration damping device according to the design requirements or construction specifications.

防止螺旋风管安装时的振动和噪音

Prevent vibration and noise during installation of spiral air ducts

②风扇和螺旋风管通过软管连接。 风扇吸入口的软管必须安装适度，以免由于软连接而减少进气口和出风口的面积，否则会引起噪音和振动。

② The fan and spiral duct are connected through hoses. The hose at the fan inlet must be installed appropriately to avoid reducing the area of the air inlet and outlet due to soft connections, otherwise it may cause noise and vibration.

③螺旋风管的制造，安装和组件连接。 连接牢固，无漏气现象，避免了泄漏声。

③ Manufacturing, installation, and component connection of spiral air ducts. The connection is firm and there is no air leakage, avoiding leakage sound.

④为了防止螺旋风管振动，在每个系统的螺旋风管的转弯处以及与风扇和出风口的连接处都安装了固定支架。

④ To prevent vibration of the spiral duct, fixed brackets are installed at the turns of each system's spiral duct and at the connections with the fan and air outlet.

螺旋风管的漏气测试螺旋风管的安装完成后，需要进行漏气测试。 根据规格，螺旋风管的漏气测试结合了漏光的合法性和漏气测试的定量检测。  3.低压系统的气密性测试； 漏气测试适用于中压系统的抽查和高压系统的检测。

After the installation of the spiral air duct is completed, a leak test is required. According to the specifications, the leakage test of the spiral air duct combines the legality of light leakage and quantitative detection of leakage test. 3. Airtightness testing of low-pressure systems; Leakage testing is applicable for spot checks of medium pressure systems and comprehensive inspections of high pressure systems.

螺旋风管的漏光检测漏光检测是对系统的螺旋风管的密封性的定性测试，它利用小孔上的强光透视。 测试方法是在黑暗环境中，在一定长度的螺旋风管上使用保护灯泡，螺旋风管中的电压不高于36V，功率大于100W。 移到另一端。 如果在测试过程中在螺旋管外部观察到光线，则表明螺旋管有泄漏点，并修复了螺旋管的泄漏。

Leakage detection of spiral air ducts is a qualitative test of the sealing performance of the system's spiral air ducts, which utilizes strong light perspective on small holes. The testing method is to use a protective light bulb on a certain length of spiral air duct in a dark environment. The voltage in the spiral air duct should not exceed 36V and the power should be greater than 100W. Move to the other end. If light is observed outside the spiral tube during the testing process, it indicates that there is a leakage point in the spiral tube and the leakage has been repaired.
