防止鍍鋅風管震動和噪音的方法。防止震動和噪音是安裝全過程中的關鍵步驟。安裝全過程中，鍍鋅風管的震動和噪音防止主要從以下幾個方面入手:

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風扇安裝時，應根據設計要求或施工規范設置減振裝置。

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

②風機和鍍鋅風管的聯接采用軟管聯接，風機吸入口處的軟管安裝應適度松緊，避免因軟接過松而降低進出風口面積而產生噪音和震動。防止鍍鋅風管震動和噪音的方法。

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鍍鋅風管制造、安裝和與部件聯接，聯接嚴密，無漏風現象，避免漏風噪音。

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

④為了防止鍍鋅風管震動，在各系統鍍鋅風管的轉彎處，與通風機和風口的連接處設置固定支架。鍍鋅風管漏風量測試鍍鋅風管安裝后，需要進行漏風量測試。根據規范，鍍鋅風管的漏風量測試采用漏光法定性和漏風量測試定量測試相結合的方式，適用于中低壓系統的嚴密性測試；漏風量測試適用于中壓系統的抽檢和高壓系統的全部檢測。防止鍍鋅風管震動和噪音的方法。

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. Methods to prevent vibration and noise from galvanized air ducts.
