专注通风管道加工·排烟罩

1. The planning of supports and hangers for fans, air conditioning units, fan panels, and other equipment requires the provision of vibration isolators, and their types and specifications should meet the requirements of the planning and product technology documents.

2、风管笔直设备，间隔不该大于4m，单根直管起码应有2个不变点。

2. The equipment with straight air ducts should have a spacing of no more than 4m, and a single straight duct should have at least 2 fixed points.

3、吊架的螺孔应选用机械加工，吊杆应平直，螺纹无缺、光亮。

3. The screw holes of the suspension bracket should be machined, and the suspension rod should be straight, with no missing or bright threads.

4、长度超出20m的水平悬吊风管，在通风管道施工时起码配备1个防晃支架。

4. Horizontal suspended air ducts exceeding 20m in length should be equipped with at least one anti shaking support during the construction of ventilation ducts.

5、支吊架不宜配备在风口、阀门、查验门及自控组织处，离风口或插接纳的间隔不宜小于200mm。

5. Supports and hangers should not be installed at air vents, valves, inspection doors, and automatic control organizations, and the distance between them and the air vents or plugs should not be less than 200mm.

6、平悬吊的主、干风管长度超出20m时应配备防备摇摆的不变点，每个体系不该少于1个。

6. When the length of the main and main air ducts suspended horizontally exceeds 20m, they should be equipped with fixed points to prevent swaying, and each system should not be less than 1.

7、风管支吊架宜按国标图集与规范选用强度和刚度相适宜的模式和规范，关于直径或边长大于2500㎜的超宽、超重风管的支、吊架应按规划规章。

7. The support and hanger of air ducts should be selected according to the national standard atlas and specifications with suitable strength and stiffness modes and specifications. For support and hanger of ultra wide and overweight air ducts with a diameter or side length greater than 2500 mm, planning regulations should be followed.

8、设备后各副支、吊架的受力应均匀，无显着变形，风管或空调设备运用的可调隔振支、吊架的拉伸或收缩量应按规划的要求进行调度。

8. The force on each auxiliary support and hanger behind the equipment should be uniform without significant deformation. The adjustable vibration isolation support and hanger used for air ducts or air conditioning equipment should be adjusted for stretching or shrinking according to the planned requirements.

因此，在规划通风管道时，正确安置和挑选结构适宜的支吊架，能够改进通风管道的应力分散，确保通风管道的平安作业，还能够拉长通风管道的运用寿数。

Therefore, when planning ventilation ducts, the correct placement and selection of structurally suitable supports and hangers can improve the stress dispersion of the ventilation ducts, ensure safe operation of the ventilation ducts, and also extend the service life of the ventilation ducts.
