通風(fēng)管道主要應(yīng)用在工業(yè)及建筑工程中，應(yīng)用領(lǐng)域主要涉及:電子工業(yè)無塵廠房凈化系統(tǒng)，醫(yī)藥食品無菌車間凈化系統(tǒng)，酒店賓館、醫(yī)院、工廠及寫字樓的空調(diào)系統(tǒng)，工業(yè)污染控制用除塵、排煙、吸油等排風(fēng)管、工業(yè)環(huán)境或崗位舒適用送風(fēng)管、煤礦抽放瓦斯用抽放瓦斯系統(tǒng)、煤礦礦井環(huán)境控制用送回風(fēng)系統(tǒng)。

The ventilation pipe is mainly used in industrial and construction projects, mainly related to application: purification system of electronic industry clean workshop, purifying system of medicine and food aseptic workshop, hotels, hospitals, shopping malls and office buildings factory of central air-conditioning system, with the addition of dust, smoke and fume exhaust pipe, etc. industrial environment comfortable by feeding or post the wind pipe, coal mine gas drainage in coal mine gas drainage system, environmental control system of industrial pollution control air supply.

風(fēng)管及部件的安裝

Installation of wind pipe and parts

風(fēng)管及配件可拆卸的接口及調(diào)節(jié)閥門不得裝設(shè)在墻內(nèi)或樓板內(nèi)。風(fēng)管及配件安裝前應(yīng)內(nèi)外雜物及污物并保持清潔。

The detachable interface and regulating valve of the wind pipe and accessories shall not be installed in the wall or in the floor. The internal and external impurities and dirt should be cleaned and kept clean before the installation of the wind pipe and accessories.

靠墻或靠柱安裝的水平、垂直風(fēng)管宜采用懸臂支架或斜撐支架。不靠墻、柱安裝的水平風(fēng)管宜用托底吊架，垂直風(fēng)管應(yīng)采用抱箍支架，風(fēng)管b＞800mm應(yīng)加雙螺帽。并在轉(zhuǎn)角處、頂端、末端設(shè)置防晃支架，支架不得設(shè)置在風(fēng)口、閥門、檢查孔及自控機(jī)構(gòu)處。吊架不宜直接固定在法蘭片上。

A horizontal and vertical wind pipe installed on a wall or a column should be supported by a cantilever bracket or a bracing support. Do not rely on the wall and column level wind pipe installed to use underpinning hanger, vertical wind pipe should be used in hoop bracket, duct b > 800mm should add double nut. At the corner, the top and the end, the anti - sway bracket is set up. The bracket shall not be set at the air vent, valve, check hole and automatic control mechanism. The hanger should not be fixed directly on the flange.

矩形風(fēng)管抱箍支架應(yīng)緊貼風(fēng)管。如保溫風(fēng)管，應(yīng)留有保溫厚度浸瀝青的木塊風(fēng)管吊架應(yīng)平直、螺紋應(yīng)光潔、吊桿拼接可采用焊接。長度不應(yīng)少于吊桿直徑的六倍，并應(yīng)在兩側(cè)焊接。

The brackets of the hoop of the rectangular wind pipe should be tightly attached to the wind pipe. If the heat insulation pipe, the wood block hanger of the wood block should be kept straight, the thread should be smooth and the splice of the hanger can be welded. The length should not be less than six times the diameter of the hanger, and should be welded on both sides.

通風(fēng)管道一般有:凈化系統(tǒng)送回風(fēng)管、空調(diào)通風(fēng)管、工業(yè)送排風(fēng)通風(fēng)管、系統(tǒng)吸排風(fēng)管、礦用抽放瓦斯管、礦用涂膠布風(fēng)筒等。

Ventilation pipes usually include: purification system, return air pipe, central air conditioning ventilation pipe, industrial ventilation and ventilation pipe, environmental protection system suction and exhaust pipe, mine drainage gas pipe, mine coating cloth air duct and so on.

在通風(fēng)系統(tǒng)中的風(fēng)管是相互連接的一個(gè)整體，必然得遵循各支路阻力平衡規(guī)律，當(dāng)風(fēng)管系統(tǒng)的結(jié)構(gòu)形式、管道尺寸一經(jīng)確定，在一定的風(fēng)機(jī)作用下，各段的風(fēng)量是按阻力平衡規(guī)律自動分配的。在設(shè)計(jì)計(jì)算時(shí)未經(jīng)阻力平衡計(jì)算，會導(dǎo)致系統(tǒng)實(shí)際風(fēng)量分配與設(shè)計(jì)不符。

In the ventilation system of wind pipe is a whole connected, must follow the branch resistance balance law, when the structure, size of pipe duct system is confirmed, the fan under certain sections of the air volume according to the automatic distribution of resistance balance law. Without the calculation of resistance balance in the design and calculation, the actual air volume distribution and design of the system will not conform to the design.
