1. Laying principle of ventilation duct installation system

管道鋪設(shè)分明裝、暗裝，一般采用明裝。因?yàn)槊餮b以便于檢修，在無(wú)法采用明裝時(shí)考慮暗裝方式，管道盡可能的集中成列，盡量沿墻或柱子平行鋪設(shè)，若管徑大或保溫應(yīng)布局在靠墻側(cè)。一般兩根管道平行布局時(shí)，間距不小于100～200mm。

Pipeline laying shall be clearly installed and concealed, and generally open installation shall be adopted. Because the open installation is convenient for maintenance, the concealed installation method shall be considered when the open installation cannot be adopted. The pipes shall be concentrated in columns as far as possible and laid parallel along the wall or column as far as possible. If the pipe diameter is large or the thermal insulation shall be arranged near the wall. Generally, when two pipes are arranged in parallel, the spacing shall not be less than 100 ~ 200mm.

2、通風(fēng)管道加工系統(tǒng)的連接原則

2. Connection principle of ventilation duct processing system

在以焊接為主要連接方式方法的管道中，應(yīng)設(shè)置足夠數(shù)量的法蘭連接，在以螺紋為主的連接管道中應(yīng)設(shè)置足夠的活接頭，以便宜于安裝、拆卸、檢修

In the pipeline with welding as the main connection method, a sufficient number of flange connections shall be set, and in the connecting pipeline with thread as the main connection method, sufficient movable joints shall be set to make it cheaper for installation, disassembly and maintenance

3、通風(fēng)管道加工系統(tǒng)的支撐原則管道不宜與閥件直接支撐在設(shè)備上，應(yīng)單獨(dú)設(shè)置支架或吊架，管道的焊縫位置應(yīng)在施工方便或受力較小的地方，焊縫不得位于支架處且距離不小于200mm。

3. Support principle of ventilation pipe processing system: the pipe shall not be directly supported on the equipment with the valve, and the support or hanger shall be set separately. The weld of the pipe shall be located at the place where the construction is convenient or the stress is small, and the weld shall not be located at the support and the distance shall not be less than 200mm.

4、不同含塵氣體性質(zhì)不同，則凈化的分段處理應(yīng)不同。

4. If the properties of different dusty gases are different, the subsection treatment of purification should be different.

當(dāng)污染源多時(shí)可以集中在一個(gè)凈化系統(tǒng)中，也可分為幾個(gè)系統(tǒng)，但出現(xiàn)污染物混合會(huì)引起燃燒、爆炸危險(xiǎn)、不同溫度和濕度的氣體，混合后出現(xiàn)管道內(nèi)結(jié)露、粉塵或氣體性質(zhì)不同，影響回收或凈化效率的。

When there are many pollution sources, they can be concentrated in one purification system or divided into several systems. However, the mixing of pollutants will cause combustion, explosion hazards, gases with different temperatures and humidity. After mixing, condensation, dust or different gas properties in the pipeline will affect the recovery or purification efficiency.

5、通風(fēng)管道加工系統(tǒng)布局中要保證整體系統(tǒng)的漏損小，確保吸塵口的有足夠的風(fēng)量。

5. The layout of ventilation duct processing system shall ensure that the leakage of the overall system is small and that there is sufficient air volume at the dust suction port.

6、通風(fēng)管道加工系統(tǒng)布局要減小阻力。

6. The layout of ventilation duct processing system shall reduce resistance.

通風(fēng)管道安裝過程中如果安裝不好會(huì)產(chǎn)生噪音、漏風(fēng)、布局不合理造成管材浪費(fèi)等問題，都說(shuō)三分產(chǎn)品，七分安裝，安裝比產(chǎn)品本身更為重要，建議大家選擇有經(jīng)驗(yàn)的安裝團(tuán)隊(duì)

In the process of ventilation duct installation, if the installation is not good, it will produce noise, air leakage, unreasonable layout, resulting in pipe waste and other problems. It is said that there are three products and seven installation. Installation is more important than the product itself. It is recommended that you choose an experienced installation team
