通风管道厂家安装过程中振动和噪音的预防

发布人：   发布时间：2022-04-13 21:08:00

防止振动和噪音是安装过程中的一个重中之重。通风管道厂家安装过程中对通风管道振动和噪声的预防主要从以下几个方面着手：

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、安装风机时，根据设计要求或施工规范要求配置减振装置。

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

2、风机与通风管采用软管连接，风机吸入口处的软管应安装适当配合，以免因连接松动而减少进出风口面积，产生噪声和振动.

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、通风管制作、安装并与部件连接，连接密封。无漏风现象，避免漏风噪音。

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、为防止通风管道振动，各系统通风管道的转动处及与风机、出风口的连接处均装有固定支架。

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.

安装通风口后，需要进行漏气测试。按照规定，通风管道漏气检测采用轻漏合法性和定量漏气检测相结合的方式。漏光法适用于中低压系统的密封性检查;量测适用于中压系统的抽查和高压系统的检查。

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.

通风管道的漏光法检测

漏光检测是利用光线在小孔中的强透视，定性检测系统通风口的密封性的一种方法。测试方法是在黑暗环境中，在一定长度的通风管道中使用电压不高于36V、功率高于100W的带保护罩的灯泡，从管道一端缓慢移动。从通风管道的一端缓缓移向另一端，试验时若在通风管道外能观察到光线，则说明通风管道有漏点，并对通风管道的漏风处进行修补。

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.
