防止镀锌风管震动和噪音的方法。防止震动和噪音是安裝全过程中的关键步骤。安裝全过程中，镀锌风管的震动和噪音防止主要从以下几个方面入手:

Methods to prevent vibration and noise from galvanized air ducts. Preventing vibration and noise is a crucial step throughout the installation process. During the entire installation process, the vibration and noise prevention of galvanized air ducts mainly focus on the following aspects:

①风扇安裝时，应根据设计要求或施工规范设置减振装置。

① When installing fans, vibration damping devices should be set up according to design requirements or construction specifications.

②风机和镀锌风管的联接采用软管联接，风机吸入口处的软管安裝应适度松紧，避免因软接过松而降低进出风口面积而产生噪音和震动。防止镀锌风管震动和噪音的方法。

② The connection between the fan and the galvanized air duct adopts a flexible hose connection. The installation of the flexible hose at the fan inlet should be moderately loose to avoid noise and vibration caused by the reduction of the inlet and outlet area due to loose soft connections. Methods to prevent vibration and noise from galvanized air ducts.

③镀锌风管制造、安裝和与部件联接，联接严密，无漏风现象，避免漏风噪音。

③ Galvanized air duct manufacturing, installation, and connection with components, with tight connections and no air leakage, to avoid air leakage noise.

④为了防止镀锌风管震动，在各系统镀锌风管的转弯处，与通风机和风口的连接处设置固定支架。镀锌风管漏风量测试镀锌风管安裝后，需要进行漏风量测试。根据规范，镀锌风管的漏风量测试采用漏光法定性和漏风量测试定量测试相结合的方式，适用于中低压系统的严密性测试；漏风量测试适用于中压系统的抽检和高压系统的全部检测。防止镀锌风管震动和噪音的方法。

④ In order to prevent vibration of galvanized air ducts, fixed brackets are installed at the turning points of galvanized air ducts in each system, and at the connection points with ventilation fans and air vents. After the installation of galvanized air ducts, a leakage test is required. According to the specifications, the leakage test of galvanized air ducts adopts a combination of leakage detection and quantitative testing, which is suitable for the tightness test of medium and low voltage systems; The air leakage test is applicable to the sampling inspection of medium pressure systems and all inspections of high pressure systems.
