通風設備安裝過程中振動和噪音的預防，是安裝過程中一個，安裝過程中通風設備的振動和噪音的預防主要從以下幾個方面著手：
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通風設備安裝時按設計要求或施工規范要求設置減振裝置。
① During the installation of ventilation equipment, vibration damping devices shall be set according to the design requirements or construction specifications.
②通風設備相連接采用軟管連接，風機吸入口處的軟管安裝要做到松緊適度，避免因軟接過松減小進出風口面積，而引起噪聲和振動。
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通風設備制作、安裝及與部件連接，連接嚴密，無漏風現象，以免產生漏風噪音。
③ Ventilation equipment production, installation and connection with components, tight connection, no air leakage phenomenon, so as to avoid air leakage noise.
④為防止通風設備振動，在每個系統通風設備的轉彎處、與通風機和風口的連接處設固定支架。
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.
通風管道及螺旋通風管道，它們都是通風管道，而且螺旋通風管道還是通風管道中的一種，是使用比較多的一種，通風管道的種類有很多，但不管是哪一種，其基本功能作用是一樣，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：送風和通氣
Function 1: air supply and ventilation
就是送新鮮空氣和排氣，將有害氣體排出去，將室外新鮮空氣輸送到室內，一般使用通風管道是好的，如果環境比較潮濕，或者是具有腐蝕性的話，那么應使用不銹鋼，以免通風管道生銹腐蝕。
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：送冷風
Function 2: cold air supply
主要是用到空調中，不過需要在通風管道上加上保溫材料。
Mainly used in central air conditioning, but need to add insulation material in the ventilation duct.
作用三：排油煙
Function 3: exhaust fumes
主要是用在飯店、酒店等場所中，將廚房中的油煙排出，一般是使用圓形通風管道。
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：除塵，以及散裝物料的輸送
Function 4: dust removal and bulk material transportation
在工廠車間中使用通風管道來除塵，還可以用通風管道來輸送散狀顆粒，比如泡沫塑料顆粒等，因為其比重不大。
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.
