通風管道安裝過程中振動和噪音的預防振動和噪音的預防是安裝過程中一個重要環節，安裝過程中通風管道的振動和噪音的預防主要從以下幾個方面著手，
濟南通風管道加工人員為您講解。
The prevention of vibration and noise during the installation of ventilation pipes is an important link in the installation process. The prevention of vibration and noise of ventilation pipes during the installation process mainly starts from the following aspects. The ventilation pipe processing personnel in Jinan will explain to you.
①風機安裝時按設計要求或施工規范要求設置減振裝置。
① During the installation of fans, vibration damping devices shall be set according to the design requirements or construction specifications.
②風機、通風管道相連接采用軟管連接，風機吸入口處的軟管安裝要做到松緊適度，避免因軟接過松減小進出風口面積，而引起噪聲和振動。
② The fan and the ventilation pipe are connected by hoses. The hoses at the suction inlet of the fan shall be installed with proper tightness to avoid noise and vibration caused by the loose soft connection which reduces the area of the air inlet and outlet.
③通風管道制作、安裝及與部件連接，連接嚴密，無漏風現象，以免產生漏風噪音。通風管道安裝過程中振動和噪音的預防
③ The ventilation pipe shall be manufactured, installed and connected with components in a tight manner without air leakage to avoid air leakage noise. Prevention of vibration and noise during installation of ventilation pipe
④為防止通風管道振動，在每個系統通風管道的轉彎處、與通風機和風口的連接處設固定支架。
④ In order to prevent the vibration of the ventilation duct, fixed supports shall be set at the turning of the ventilation duct of each system and the connection with the ventilator and the air outlet.
通風管道的漏風量測試通風管道安裝完畢，需進行漏風量測試，依據規范規定，通風管道的漏風量檢測采用漏光法定性和漏風量測試定量檢測相結合的方式，漏光法適合于中、低壓系統的嚴密性檢驗;漏風量測試適合于中壓系統的抽檢和高壓系統的悉數檢測。通風管道的漏光法檢測漏光法檢測是采用光線對小孔的強透視力，對系統通風管道嚴密程度進行定性檢測的方法。
Air leakage test of the ventilation duct after the installation of the ventilation duct, the air leakage test shall be conducted. According to the specification, the air leakage test of the ventilation duct adopts the method of combining the legal and quantitative detection of the light leakage. The light leakage method is suitable for the tightness test of the medium and low pressure systems; Air leakage test is suitable for sampling inspection of medium pressure system and full inspection of high pressure system. Light leakage detection of ventilation duct light leakage detection is a method to qualitatively detect the tightness of the ventilation duct of the system by using the strong penetrating vision of the light to the small hole.
測量鍍鋅風管漏風量時不能忽略的要點特別需要注意到的是我們在測量該鍍鋅風管的漏風量的時候在晚上進行，保證四周環境較暗，將100W帶保護罩的低壓照明燈置于風管內側或外側，沿檢測部位與接縫作緩慢移動，在另一側進行觀察，當發現有光線射出，則說明查到明顯漏風部位，并作好記錄。
The key points that cannot be ignored when measuring the air leakage of the galvanized air duct are that we measure the air leakage of the galvanized air duct at night to ensure that the surrounding environment is dark. Place the 100W low-voltage lamp with protective cover on the inside or outside of the air duct, move slowly along the detection position and joint, and observe on the other side. If light is found, it indicates that there is obvious air leakage, and make records.
