①通風(fēng)設(shè)備安裝時(shí)按設(shè)計(jì)要求或施工規(guī)范要求設(shè)置減振裝置。

① During the installation of ventilation equipment, damping devices shall be set according to the design requirements or construction specifications.

②通風(fēng)設(shè)備相連接采用軟管連接，風(fēng)機(jī)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(jìn)出風(fēng)口面積，而引起噪聲和振動(dòng)。

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通風(fēng)設(shè)備制作、安裝及與部件連接，連接嚴(yán)密，無漏風(fēng)現(xiàn)象，以免產(chǎn)生漏風(fēng)噪音。

③ The ventilation equipment shall be manufactured, installed and connected with components tightly without air leakage to avoid air leakage noise.

④為防止通風(fēng)設(shè)備振動(dòng)，在每個(gè)系統(tǒng)通風(fēng)設(shè)備的轉(zhuǎn)彎處、與通風(fēng)機(jī)和風(fēng)口的連接處設(shè)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.

通風(fēng)管道及螺旋通風(fēng)管道，它們都是通風(fēng)管道，而且螺旋通風(fēng)管道還是通風(fēng)管道中的一種，是使用比較多的一種，通風(fēng)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 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：送風(fēng)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(nèi)，一般使用通風(fēng)管道是好的，如果環(huán)境比較潮濕，或者是具有腐蝕性的話，那么應(yīng)使用不銹鋼，以免通風(fēng)管道生銹腐蝕。

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：送冷風(fēng)

Function 2: supply cold air

主要是用到空調(diào)中，不過需要在通風(fēng)管道上加上保溫材料。

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

作用三：排油煙

Function 3: exhaust oil fume

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(fēng)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：除塵，以及散裝物料的輸送

Function 4: dust removal and transportation of bulk materials

在工廠車間中使用通風(fēng)管道來除塵，還可以用通風(fēng)管道來輸送散狀顆粒，比如泡沫塑料顆粒等，因?yàn)槠浔戎夭淮蟆?/p>

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.
