振動(dòng)和噪音的預(yù)防是安裝過(guò)程中一個(gè)，濟(jì)南通風(fēng)管道加工廠家認(rèn)為安裝過(guò)程中通風(fēng)管道的振動(dòng)和噪音的預(yù)防主要從以下幾個(gè)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(fēng)機(jī)安裝時(shí)按設(shè)計(jì)要求或施工規(guī)范要求設(shè)置減振裝置。

① During fan installation, vibration damping devices shall be set according to design requirements or construction specifications.

②風(fēng)機(jī)、通風(fēng)管道相連接采用軟管連接，風(fēng)機(jī)吸入口處的軟管安裝要做到松緊適度，避免因軟接過(guò)松減小進(jìn)出風(fēng)口面積，而引起噪聲和振動(dòng)。

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(fēng)管道制作、安裝及與部件連接，連接嚴(yán)密，無(wú)漏風(fēng)現(xiàn)象，以免產(chǎn)生漏風(fēng)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(fēng)管道振動(dòng)，在每個(gè)系統(tǒng)通風(fēng)管道的轉(zhuǎn)彎處、與通風(fēng)機(jī)和風(fēng)口的連接處設(shè)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(fēng)管道安裝完畢，需進(jìn)行漏風(fēng)量測(cè)試，依據(jù)規(guī)范規(guī)定，通風(fēng)管道的漏風(fēng)量檢測(cè)采用漏光法定性和漏風(fēng)量測(cè)試定量檢測(cè)相結(jié)合的方式，漏光法適合于中、低壓系統(tǒng)的嚴(yán)密性檢驗(yàn)；漏風(fēng)量測(cè)試適合于中壓系統(tǒng)的抽檢和高壓系統(tǒng)的悉數(shù)檢測(cè)。

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(cè)是采用光線對(duì)小孔的強(qiáng)透視力，對(duì)系統(tǒng)通風(fēng)管道嚴(yán)密程度進(jìn)行定性檢測(cè)的方法。其試驗(yàn)方法是在一定長(zhǎng)度的通風(fēng)管道上，在黑暗的環(huán)境下，在通風(fēng)管道內(nèi)用一個(gè)電壓不高于36V、功率在100W以上的帶保護(hù)罩的燈泡，從通風(fēng)管道的一端緩緩移向另一端，試驗(yàn)時(shí)若在通風(fēng)管道外能觀察到光線，則說(shuō)明通風(fēng)管道有漏點(diǎn)，并對(duì)通風(fēng)管道的漏風(fēng)處進(jìn)行修補(bǔ)。

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(fēng)管道的漏光法檢測(cè)采用分段檢測(cè)、匯總分析的方法，被測(cè)系統(tǒng)的通風(fēng)管道不允許有多處條縫形的明顯漏光，低壓系統(tǒng)通風(fēng)管道每10米接縫，漏光點(diǎn)不超過(guò)2處，100米接縫平均不大于16處；中壓系統(tǒng)通風(fēng)管道每10接縫，漏光點(diǎn)不超過(guò)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.
