通風(fēng)管道安裝時，振動和噪音的降低是很有必要的，重要從以下幾個方面著手：
It is necessary to reduce the vibration and noise during the installation of ventilation pipes. The following aspects are important:
①離心通風(fēng)機組裝后按方案設(shè)計要求或施工技術(shù)要求設(shè)置避震機器設(shè)備。
① After the centrifugal fan is assembled, shock absorption machines and equipment shall be set according to the design requirements or construction technical requirements.
②離心通風(fēng)機、通風(fēng)管道相互連接采用塑料管連接，離心通風(fēng)機吸進口的塑料管組裝要確保緊松適度，避免因軟收到松降低進通風(fēng)孔占地面積，而引起噪聲和振動。
② The centrifugal fan and ventilation pipe are connected by plastic pipe. The plastic pipe at the suction inlet of the centrifugal fan shall be assembled in a tight and loose manner to avoid noise and vibration caused by reducing the floor area of the ventilation hole due to soft reception.
③通風(fēng)管道制作、安裝及與預(yù)制構(gòu)件連接，連接嚴密，無漏風(fēng)情況，防止導(dǎo)致漏風(fēng)噪音。
③ The production, installation and connection of ventilation pipes with prefabricated components shall be tight without air leakage to prevent air leakage noise.
④為防止通風(fēng)管道振動，在每一個系統(tǒng)通風(fēng)管道的轉(zhuǎn)彎處、與排煙風(fēng)機和通風(fēng)口的相接處設(shè)固定支架。
④ In order to prevent the vibration of ventilation ducts, fixed supports shall be set at the corners of each system ventilation duct and at the joints with smoke exhaust fans and vents.

通風(fēng)管道的漏風(fēng)量檢測通風(fēng)管道組裝完畢，需進行漏風(fēng)量檢測，依據(jù)規(guī)范標準，通風(fēng)管道的漏風(fēng)量檢測采用漏光法律法規(guī)性與漏風(fēng)量檢測定量分析檢測緊密聯(lián)系的辦法，漏光法適合于中、低壓系統(tǒng)的密閉性檢測;漏風(fēng)量檢測適合于髙壓系統(tǒng)軟件的抽樣檢查和高壓系統(tǒng)的盡數(shù)檢測。
Air leakage detection of the ventilation duct After the assembly of the ventilation duct, the air leakage detection shall be carried out. According to the specifications and standards, the air leakage detection of the ventilation duct adopts the method that the light leakage laws and regulations are closely linked with the quantitative analysis and detection of the air leakage detection. The light leakage method is suitable for the tightness detection of medium and low pressure systems; Air leakage detection is suitable for sampling inspection of high pressure system software and full detection of high pressure system.
通風(fēng)管道的漏光法檢測漏光法檢測是采用燈源對小孔的強透視力，德裕建筑安裝工程有限公司對系統(tǒng)通風(fēng)管道嚴密水準進行判斷檢測的形式，其試驗方式就是在一定長度的通風(fēng)管道上，在黑喑自然環(huán)境下，在通風(fēng)管道內(nèi)用一個工作標準電壓不太高過36V、功率在100W之上的帶保護罩的燈泡，從通風(fēng)管道的一端漸漸地調(diào)向另一端，試驗時如果在通風(fēng)管道外能觀察到燈源，則說明通風(fēng)管道有漏掉，對其通風(fēng)管道的漏風(fēng)處進行修護。
Light leak detection of ventilation duct Light leak detection is a way to use the light source to have a strong vision of small holes. Deyu Construction and Installation Engineering Co., Ltd. judges and detects the tightness level of the system ventilation duct. The test method is to use a bulb with a protective cover in the ventilation duct with a working standard voltage not too high than 36V and a power above 100W on a certain length of ventilation duct in a dark and silent natural environment, Gradually adjust from one end of the ventilation duct to the other end. If the light source can be observed outside the ventilation duct during the test, it means that the ventilation duct has leakage, and repair the air leakage part of the ventilation duct.
