通风管道安装时，振动和噪音的降低是很有必要的，重要从以下几个方面着手：
It is necessary to reduce the vibration and noise during the installation of ventilation pipes. The following aspects are important:
①离心通风机组装后按方案设计要求或施工技术要求设置避震机器设备。
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离心通风机、通风管道相互连接采用塑料管连接，离心通风机吸进口的塑料管组装要确保紧松适度，避免因软收到松降低进通风孔占地面积，而引起噪声和振动。
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通风管道制作、安装及与预制构件连接，连接严密，无漏风情况，防止导致漏风噪音。
③ The production, installation and connection of ventilation pipes with prefabricated components shall be tight without air leakage to prevent air leakage noise.
④为防止通风管道振动，在每一个系统通风管道的转弯处、与排烟风机和通风口的相接处设固定支架。
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.

通风管道的漏风量检测通风管道组装完毕，需进行漏风量检测，依据规范标准，通风管道的漏风量检测采用漏光法律法规性与漏风量检测定量分析检测紧密联系的办法，漏光法适合于中、低压系统的密闭性检测;漏风量检测适合于髙压系统软件的抽样检查和高压系统的尽数检测。
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.
通风管道的漏光法检测漏光法检测是采用灯源对小孔的强透视力，德裕建筑安装工程有限公司对系统通风管道严密水准进行判断检测的形式，其试验方式就是在一定长度的通风管道上，在黑喑自然环境下，在通风管道内用一个工作标准电压不太高过36V、功率在100W之上的带保护罩的灯泡，从通风管道的一端渐渐地调向另一端，试验时如果在通风管道外能观察到灯源，则说明通风管道有漏掉，对其通风管道的漏风处进行修护。
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.
