振動和噪音的預防是安裝過程中一個，
濟南通風管道加工廠家認為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：
The prevention of vibration and noise is a key point in the installation process. Jinan ventilation pipe manufacturers believe that the prevention of vibration and noise of ventilation pipes during the installation process mainly starts from the following aspects:
①風機安裝時按設計要求或施工規(guī)范要求設置減振裝置。
① During fan installation, vibration damping devices shall be set according to 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 fans and ventilation pipes shall be connected by hoses. The hoses at the suction inlet of the fans shall be installed with proper tightness to avoid noise and vibration caused by loose flexible connections that reduce the area of 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(xiàn)象，以免產(chǎn)生漏風噪音。
③ The fabrication, installation and connection of ventilation pipes with components shall be tight without air leakage to avoid air leakage noise.
④為防止通風管道振動，在每個系統(tǒng)通風管道的轉(zhuǎn)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, a fixed support shall be set at the turning of the ventilation duct of each system and the connection with the ventilator and the air outlet.
通風管道安裝完畢，需進行漏風量測試，依據(jù)規(guī)范規(guī)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(jié)合的方式，漏光法適合于中、低壓系統(tǒng)的嚴密性檢驗；漏風量測試適合于中壓系統(tǒng)的抽檢和高壓系統(tǒng)的悉數(shù)檢測。
After the installation of the ventilation duct, the air leakage test shall be conducted. According to the specifications, the air leakage test of the ventilation duct shall adopt the method of combining the legal detection of light leakage and the quantitative detection of air leakage test. The light leakage method is suitable for the tightness inspection of the medium and low pressure systems; The air leakage test is suitable for sampling inspection of medium pressure system and full inspection of high pressure system.
漏光法檢測是采用光線對小孔的強透視力，對系統(tǒng)通風管道嚴密程度進行定性檢測的方法。其試驗方法是在一定長度的通風管道上，在黑暗的環(huán)境下，在通風管道內(nèi)用一個電壓不高于36V、功率在100W以上的帶保護罩的燈泡，從通風管道的一端緩緩移向另一端，試驗時若在通風管道外能觀察到光線，則說明通風管道有漏點，并對通風管道的漏風處進行修補。
The light leakage detection is a qualitative detection method of the tightness of the ventilation duct of the system by using the strong vision of light to the small hole. The test method is to use a bulb with a protective cover with a voltage not higher than 36V and a power of more than 100W in the ventilation duct on a certain length of ventilation duct and in a dark environment, and slowly move it from one end of the ventilation duct to the other end. If light can be observed outside the ventilation duct during the test, it means that there is a leak in the ventilation duct, and repair the air leak of the ventilation duct.
系統(tǒng)通風管道的漏光法檢測采用分段檢測、匯總分析的方法，被測系統(tǒng)的通風管道不允許有多處條縫形的明顯漏光，低壓系統(tǒng)通風管道每10米接縫，漏光點不超過2處，100米接縫平均不大于16處；中壓系統(tǒng)通風管道每10接縫，漏光點不超過1處，100米接縫平均不大于8處為合格。
The method of sectional detection and summary analysis is adopted for the detection of light leakage of the ventilation pipes of the system. The ventilation pipes of the tested system are not allowed to have multiple obvious light leakage in the shape of slits. The light leakage points of the ventilation pipes of the low-pressure system are not more than 2 per 10m joint, and the average number of joints is not more than 16 per 100m; For every 10 joints of the ventilation pipe of the medium pressure system, the light leakage point is not more than 1, and the average joint of 100 meters is not more than 8.
