通风设备安装过程中振动和噪音的预防，是安装过程中一个重 点，安装过程中通风设备的振动和噪音的预防主要从以下几个方面着手：
The prevention of vibration and noise in the installation process of ventilation equipment is a key point in the installation process. The prevention of vibration and noise in the installation process of ventilation equipment mainly starts from the following aspects:
①通风设备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 ventilation equipment, vibration damping devices shall be set according to the design requirements or construction specifications.
②通风设备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 ventilation equipment is connected by flexible pipes. The installation of the flexible pipes at the suction inlet of the fan should be appropriately tight to avoid noise and vibration caused by the loose soft connection and reducing the area of the air inlet and outlet.
③通风设备制作、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。
③ Ventilation equipment production, installation and connection with components, tight connection, no air leakage phenomenon, so as to avoid air leakage noise.
④为防止通风设备振动，在每个系统通风设备的转弯处、与通风机和风口的连接处设固定支架。
④ In order to prevent the vibration of ventilation equipment, fixed support is set at the corner of ventilation equipment of each system and the connection with fan and air outlet.
通风管道及螺旋通风管道，它们都是通风管道，而且螺旋通风管道还是通风管道中的一种，是使用比较多的一种，通风管道的种类有很多，但不管是哪一种，其基本功能作用是一样，其主要有：
Ventilation pipe and spiral ventilation pipe are both ventilation pipes. Spiral ventilation pipe is one of the ventilation pipes, which is widely used. There are many kinds of ventilation pipes, but no matter which one is, its basic functions are the same. Its main functions are as follows:
作用一：送风和通气
Function 1: air supply and ventilation
就是送新鲜空气和排气，将有害气体排出去，将室外新鲜空气输送到室内，一般使用通风管道是好的，如果环境比较潮湿，或者是具有腐蚀性的话，那么应使用不锈钢，以免通风管道生锈腐蚀。
It is to send fresh air and exhaust, to discharge harmful gases, to transport outdoor fresh air to indoor, generally using ventilation pipe is good, if the environment is humid, or corrosive, then stainless steel should be used to avoid rust and corrosion of ventilation pipe.
作用二：送冷风
Function 2: cold air supply
主要是用到中 央空调中，不过需要在通风管道上加上保温材料。
Mainly used in central air conditioning, but need to add insulation material in the ventilation duct.
作用三：排油烟
Function 3: exhaust fumes
主要是用在饭店、酒店等场所中，将厨房中的油烟排出，一般是使用圆形通风管道。
It is mainly used in restaurants, hotels and other places to exhaust the oil smoke in the kitchen. Generally, circular ventilation pipes are used.
作用四：除尘，以及散装物料的输送
Function 4: dust removal and bulk material transportation
在工厂车间中使用通风管道来除尘，还可以用通风管道来输送散状颗粒，比如泡沫塑料颗粒等，因为其比重不大。
Ventilation pipes are used for dust removal in factory workshops, and ventilation pipes can be used for conveying granular particles, such as foam plastic particles, etc., because their proportion is not large.
