The installation of general smoke exhaust fan system software and air conditioning unit shall be carried out after the construction of house building bent structure project, the obstacles have been removed and the road surface is free of dirt.

管道不可立即支撐點(diǎn)在含有各種閥門的機(jī)器設(shè)備上，支撐架或支架應(yīng)獨(dú)立設(shè)定。管道焊接應(yīng)坐落于工程施工便捷或地應(yīng)力小的地區(qū)。焊接不可坐落于支撐架處，間距不可低于200mm

The pipe cannot be supported immediately. The support frame or support shall be set independently on the machinery and equipment containing various valves. The pipeline welding shall be located in the area with convenient engineering construction or low in-situ stress. Welding shall not be located at the support frame, and the spacing shall not be less than 200mm

排煙系統(tǒng)通風(fēng)管道布局的一般標(biāo)準(zhǔn)：

General standards for layout of ventilation ducts of smoke exhaust system:

1.不一樣的煙塵汽體具備不一樣的特性，因而清潔應(yīng)在不一樣的一部分開展解決。

1. Different soot vapors have different characteristics, so cleaning should be carried out in different parts.

當(dāng)污染物長期集中化在一個(gè)凈化設(shè)備里時(shí)，他們能夠分成好多個(gè)系統(tǒng)軟件。殊不知，空氣污染物的混和會(huì)造成 點(diǎn)燃、發(fā)生爆炸風(fēng)險(xiǎn)及其不一樣溫度和環(huán)境濕度的汽體?；旌秃螅艿乐袝?huì)出現(xiàn)冷疑、塵土或不一樣特性的汽體，危害收購或清潔率。

When pollutants are concentrated in one purification equipment for a long time, they can be divided into many system software. As everyone knows, the mixing of air pollutants will cause ignition, explosion risk and steam with different temperature and environmental humidity. After mixing, cold doubt, dust or steam with different characteristics will appear in the pipeline, endangering the purchase or cleaning efficiency.

通風(fēng)管道

Ventilation duct

2.管道系統(tǒng)軟件合理布局應(yīng)降低摩擦阻力

2. Reasonable layout of pipeline system software shall reduce friction resistance

一般來說，環(huán)形風(fēng)管抗壓強(qiáng)度大，原材料耗費(fèi)少，但占有室內(nèi)空間大。矩形框管道占有室內(nèi)空間小，便于布局，但也必須遵照具體室內(nèi)空間。

Generally speaking, the annular air duct has high compressive strength and low consumption of raw materials, but it occupies a large indoor space. Rectangular frame pipe occupies a small indoor space and is convenient for layout, but it must also follow the specific indoor space.

3.管道系統(tǒng)軟件的鋪設(shè)標(biāo)準(zhǔn)

3. Laying standard of pipeline system software

管道鋪裝有二種種類：敞開式和內(nèi)藏式。維護(hù)保養(yǎng)一般選用敞開式安裝。當(dāng)不可以選用敞開式安裝時(shí)，考慮到掩藏安裝方法。管道應(yīng)盡量成形布局，并沿墻或柱平行面鋪設(shè)。假如管經(jīng)很大或隔熱保溫應(yīng)建在墻側(cè)。一般狀況下，兩根管道平行面布局時(shí)，間隔不可低于100~200mm

There are two types of pipe pavement: open type and built-in type. Generally, open installation is selected for maintenance. When open installation cannot be selected, the concealed installation method shall be considered. The pipes shall be laid in a shaped layout as far as possible and shall be laid along the parallel plane of the wall or column. If the pipe is large or insulated, it should be built on the side of the wall. Generally, when two pipes are arranged in parallel, the spacing shall not be less than 100 ~ 200mm
