防止振動和噪音是安裝過程中的一個重中之重。通風(fēng)管道廠家安裝過程中對通風(fēng)管道振動和噪聲的預(yù)防主要從以下幾個方面著手：

Preventing vibration and noise is a top priority during installation. The prevention of vibration and noise of ventilation duct during the installation of ventilation duct manufacturers mainly starts from the following aspects:

1、安裝風(fēng)機時，根據(jù)設(shè)計要求或施工規(guī)范要求配置減振裝置。

1. When installing the fan, the vibration damping device shall be equipped according to the design requirements or construction specifications.

2、風(fēng)機與通風(fēng)管采用軟管連接，風(fēng)機吸入口處的軟管應(yīng)安裝適當(dāng)配合，以免因連接松動而減少進(jìn)出風(fēng)口面積，產(chǎn)生噪聲和振動.

2. The fan and ventilation pipe are connected by hose. The hose at the suction inlet of the fan shall be installed with proper coordination to avoid reducing the area of inlet and outlet due to loose connection, resulting in noise and vibration

3、通風(fēng)管制作、安裝并與部件連接，連接密封。無漏風(fēng)現(xiàn)象，避免漏風(fēng)噪音。

3. The ventilation pipe shall be fabricated, installed and connected with components, and the connection shall be sealed. No air leakage and avoid air leakage noise.

4、為防止通風(fēng)管道振動，各系統(tǒng)通風(fēng)管道的轉(zhuǎn)動處及與風(fēng)機、出風(fēng)口的連接處均裝有固定支架。

4. In order to prevent the vibration of the ventilation duct, the rotation of the ventilation duct of each system and the connection with the fan and air outlet are equipped with fixed supports.

通風(fēng)管道的安裝

Installation of ventilation duct

安裝通風(fēng)口后，需要進(jìn)行漏氣測試。按照規(guī)定，通風(fēng)管道漏氣檢測采用輕漏合法性和定量漏氣檢測相結(jié)合的方式。漏光法適用于中低壓系統(tǒng)的密封性檢查;量測適用于中壓系統(tǒng)的抽查和高壓系統(tǒng)的檢查。

After installing the vent, an air leakage test is required. According to the regulations, the air leakage detection of ventilation pipeline adopts the combination of light leakage legitimacy and quantitative air leakage detection. The light leakage method is applicable to the sealing inspection of medium and low pressure systems; Measurement is applicable to spot check of medium voltage system and inspection of high voltage system.

通風(fēng)管道的漏光法檢測

Light leakage detection of ventilation duct

漏光檢測是利用光線在小孔中的強透視，定性檢測系統(tǒng)通風(fēng)口的密封性的一種方法。測試方法是在黑暗環(huán)境中，在一定長度的通風(fēng)管道中使用電壓不高于36V、功率高于100W的帶保護(hù)罩的燈泡，從管道一端緩慢移動。從通風(fēng)管道的一端緩緩移向另一端，試驗時若在通風(fēng)管道外能觀察到光線，則說明通風(fēng)管道有漏點，并對通風(fēng)管道的漏風(fēng)處進(jìn)行修補。

Light leakage detection is a method to qualitatively detect the tightness of the system vent by using the strong perspective of light in the small hole. The test method is to move the power from one end of the duct with a protective cover that is not necessarily higher than 100V in the dark. Slowly move from one end of the ventilation pipe to the other end. If light can be observed outside the ventilation pipe during the test, it indicates that there is a leakage point in the ventilation pipe, and repair the air leakage point of the ventilation pipe.
