①安裝風扇時，請根據設計要求或施工規范安裝減振裝置。

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

防止螺旋風管安裝時的振動和噪音

Prevent vibration and noise during installation of spiral air ducts

②風扇和螺旋風管通過軟管連接。 風扇吸入口的軟管必須安裝適度，以免由于軟連接而減少進氣口和出風口的面積，否則會引起噪音和振動。

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螺旋風管的制造，安裝和組件連接。 連接牢固，無漏氣現象，避免了泄漏聲。

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

④為了防止螺旋風管振動，在每個系統的螺旋風管的轉彎處以及與風扇和出風口的連接處都安裝了固定支架。

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.

螺旋風管的漏氣測試螺旋風管的安裝完成后，需要進行漏氣測試。 根據規格，螺旋風管的漏氣測試結合了漏光的合法性和漏氣測試的定量檢測。  3.低壓系統的氣密性測試； 漏氣測試適用于中壓系統的抽查和高壓系統的全面檢測。

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.

螺旋風管的漏光檢測漏光檢測是對系統的螺旋風管的密封性的定性測試，它利用小孔上的強光透視。 測試方法是在黑暗環境中，在一定長度的螺旋風管上使用保護燈泡，螺旋風管中的電壓不高于36V，功率大于100W。 移到另一端。 如果在測試過程中在螺旋管外部觀察到光線，則表明螺旋管有泄漏點，并修復了螺旋管的泄漏。

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.
