通风管道安装过程中振动和噪音的预防振动和噪音的预防是安装过程中一个重要环节，安装过程中通风管道的振动和噪音的预防主要从以下几个方面着手，
济南通风管道加工人员为您讲解。
The prevention of vibration and noise during the installation of ventilation pipes is an important link in the installation process. The prevention of vibration and noise of ventilation pipes during the installation process mainly starts from the following aspects. The ventilation pipe processing personnel in Jinan will explain to you.
①风机安装时按设计要求或施工规范要求设置减振装置。
① During the installation of fans, vibration damping devices shall be set according to the design requirements or construction specifications.
②风机、通风管道相连接采用软管连接，风机吸入口处的软管安装要做到松紧适度，避免因软接过松减小进出风口面积，而引起噪声和振动。
② The fan and the ventilation pipe are connected by hoses. The hoses at the suction inlet of the fan shall be installed with proper tightness to avoid noise and vibration caused by the loose soft connection which reduces the area of the air inlet and outlet.
③通风管道制作、安装及与部件连接，连接严密，无漏风现象，以免产生漏风噪音。通风管道安装过程中振动和噪音的预防
③ The ventilation pipe shall be manufactured, installed and connected with components in a tight manner without air leakage to avoid air leakage noise. Prevention of vibration and noise during installation of ventilation pipe
④为防止通风管道振动，在每个系统通风管道的转弯处、与通风机和风口的连接处设固定支架。
④ In order to prevent the vibration of the ventilation duct, fixed supports shall be set at the turning of the ventilation duct of each system and the connection with the ventilator and the air outlet.
通风管道的漏风量测试通风管道安装完毕，需进行漏风量测试，依据规范规定，通风管道的漏风量检测采用漏光法定性和漏风量测试定量检测相结合的方式，漏光法适合于中、低压系统的严密性检验;漏风量测试适合于中压系统的抽检和高压系统的悉数检测。通风管道的漏光法检测漏光法检测是采用光线对小孔的强透视力，对系统通风管道严密程度进行定性检测的方法。
Air leakage test of the ventilation duct after the installation of the ventilation duct, the air leakage test shall be conducted. According to the specification, the air leakage test of the ventilation duct adopts the method of combining the legal and quantitative detection of the light leakage. The light leakage method is suitable for the tightness test of the medium and low pressure systems; Air leakage test is suitable for sampling inspection of medium pressure system and full inspection of high pressure system. Light leakage detection of ventilation duct light leakage detection is a method to qualitatively detect the tightness of the ventilation duct of the system by using the strong penetrating vision of the light to the small hole.
测量镀锌风管漏风量时不能忽略的要点特别需要注意到的是我们在测量该镀锌风管的漏风量的时候在晚上进行，保证四周环境较暗，将100W带保护罩的低压照明灯置于风管内侧或外侧，沿检测部位与接缝作缓慢移动，在另一侧进行观察，当发现有光线射出，则说明查到明显漏风部位，并作好记录。
The key points that cannot be ignored when measuring the air leakage of the galvanized air duct are that we measure the air leakage of the galvanized air duct at night to ensure that the surrounding environment is dark. Place the 100W low-voltage lamp with protective cover on the inside or outside of the air duct, move slowly along the detection position and joint, and observe on the other side. If light is found, it indicates that there is obvious air leakage, and make records.
