The installation of ventilation pipe hanger is a very important link in the construction of ventilation pipe. It plays the role of supporting weight, balancing medium reaction, limiting displacement and preventing vibration. Next, Jinan ventilation duct processing factory will show you the regulations on ceiling installation during ventilation duct construction:

1、風(fēng)機(jī)、空調(diào)機(jī)組、風(fēng)機(jī)盤等設(shè)備的支、吊架設(shè)計要求設(shè)置隔振器，其品種、規(guī)格應(yīng)符合設(shè)計及產(chǎn)品技術(shù)文件要求。

1. The supports and hangers of fans, air conditioning units, fan panels and other equipment shall be designed with vibration isolators, and their varieties and specifications shall meet the requirements of the design and product technical documents.

2、風(fēng)管支丶吊架宜按國標(biāo)圖集與規(guī)范選用強(qiáng)度和剛度相適應(yīng)的形式和規(guī)格，對于直徑或邊長大于2500㎜的超寬、超重特殊風(fēng)管的支、吊架應(yīng)按設(shè)計規(guī)定。

2. The support and hanger of air duct shall be in the form and specification corresponding to the strength and stiffness according to the national standard atlas and specifications. The support and hanger of ultra wide and overweight special air duct with diameter or side length greater than 2500 mm shall be in accordance with the design regulations.

3、風(fēng)管垂直安裝，間距不應(yīng)大于4m，單根直管少應(yīng)有2個固定點。

3. The air duct shall be installed vertically, the spacing shall not be greater than 4m, and a single straight pipe shall have at least 2 fixing points.

4、當(dāng)水平懸吊的主、干風(fēng)管長度超過20m時應(yīng)設(shè)置防止擺動的固定點，每個系統(tǒng)不應(yīng)少于1個。

4. When the length of horizontally suspended main and main air ducts exceeds 20m, fixed points to prevent swing shall be set, and each system shall not be less than 1.

5、吊架的螺孔應(yīng)采用機(jī)械加工，吊桿應(yīng)平直，螺紋完整、光潔。

5. The screw hole of the hanger shall be machined, the hanger rod shall be straight, and the thread shall be complete and smooth.

6、支、吊架不宜設(shè)置在風(fēng)口、閥門、檢查門及自控機(jī)構(gòu)處，離風(fēng)口或插接管的距離不宜小于200mm。

6. The supports and hangers shall not be set at the air outlet, valve, inspection door and automatic control mechanism, and the distance from the air outlet or plug-in pipe shall not be less than 200mm.

7、長度超過20m的水平懸吊風(fēng)管，應(yīng)設(shè)置少1個防晃支架。

7. Horizontal suspended air ducts with a length of more than 20m shall be provided with at least one anti sway support.

8、安裝后各副支、吊架的受力應(yīng)均勻，無明顯變形，風(fēng)管或空調(diào)設(shè)備使用的可調(diào)隔振支、吊架的拉伸或壓縮量應(yīng)按設(shè)計的要求進(jìn)行調(diào)整。

8. After installation, the stress of each auxiliary support and hanger shall be uniform without obvious deformation. The tension or compression of adjustable vibration isolation support and hanger used for air duct or air conditioning equipment shall be adjusted according to the design requirements.

在通風(fēng)管道設(shè)，合理布置和正確選擇結(jié)構(gòu)合適的支吊架，能改善通風(fēng)管道的應(yīng)力分布，確保通風(fēng)管道運行并延長通風(fēng)管道的使用壽命。

In the design of ventilation duct, reasonable layout and correct selection of supports and hangers with appropriate structure can improve the stress distribution of ventilation duct, ensure the safe operation of ventilation duct and prolong the service life of ventilation duct.
