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, 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 shall be connected by hose. The hose at the suction inlet of the fan shall be installed with appropriate tightness to avoid noise and vibration due to loose soft connection and reducing the area of 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 The ventilation equipment shall be manufactured, installed and connected with components tightly without air leakage 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 vibration of ventilation equipment, fixed supports shall be set at the turning of ventilation equipment of each system and the connection with ventilator 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 duct and spiral ventilation duct are both ventilation ducts, and spiral ventilation duct is one of ventilation ducts, which is used more. There are many types of ventilation ducts, but no matter which one, its basic functions are the same, mainly including:

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, discharge harmful gases, and transport outdoor fresh air indoors. Generally, it is good to use ventilation pipes. If the environment is humid or corrosive, stainless steel should be used to avoid rust and corrosion of ventilation pipes.

作用二：送冷风

Function 2: supply cold air

主要是用到空调中，不过需要在通风管道上加上保温材料。

It is mainly used in central air conditioning, but thermal insulation materials need to be added to the ventilation duct.

作用三：排油烟

Function 3: exhaust oil fume

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 discharge the oil fume 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 transportation of bulk materials

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.
