通风管道的防腐保温和安装吊架要注意什么?

来源:http://www.jnqsg.com/     发布时间:2024-03-17  

通常使用镀锌风管,不锈钢管用于腐蚀性和特别潮湿的地方。当环境空气湿度较高时,风道外壁应进行防腐防锈处理。输送高温高湿的风道内壁应喷涂磷化底漆或其他防腐涂料。当风道输送高温气体或低温空气时,风道外壁应进行保温(冷保)处理。

Galvanized air ducts are usually used, while stainless steel pipes are used in corrosive and particularly humid areas. When the ambient air humidity is high, the outer wall of the air duct should be treated with anti-corrosion and rust prevention. The inner wall of the air duct conveying high temperature and high humidity should be sprayed with phosphating primer or other anti-corrosion coatings. When the air duct transports high-temperature gas or low-temperature air, the outer wall of the air duct should be insulated (cold preserved).

输送高温气体的风道的隔热目的是防止管道中空气的热量损失(冬季出现在集中式空调系统中)。在输送废热蒸汽或高温气体时,为了防止热量传递到室内并使室温升高,可以防止人再次接触风管并烫伤。在夏季,当输送气体的温度低于周围环境的空气露点温度时,通风管道外壁会产生冷凝现象。空调系统的空气管道会增加冷却损失,冷凝水滴会污染天花板和墙壁地板。因此,还应进行冷却和隔热处理。

The insulation purpose of the air duct transporting high-temperature gas is to prevent heat loss of the air in the pipeline (which occurs in centralized air conditioning systems in winter). When transporting waste heat steam or high-temperature gas, in order to prevent heat from being transferred indoors and raise the room temperature, it is possible to prevent people from coming into contact with the air duct again and getting burned. In summer, when the temperature of the transported gas is lower than the dew point temperature of the surrounding air, condensation will occur on the outer wall of the ventilation duct. The air ducts of the central air conditioning system will increase cooling losses, and condensation droplets will contaminate the ceiling and walls and floors. Therefore, cooling and insulation treatment should also be carried out.

以上是通风管道防腐保温的原因。只有防腐才能减少后期使用中的腐蚀,所以我们应该注意这些方面,并尽量保证在以后使用时更光滑,效果更好。

The above are the reasons for the anti-corrosion and insulation of ventilation ducts. Only anti-corrosion can reduce corrosion in later use, so we should pay attention to these aspects and try to ensure smoother and better results in future use.

关于通风管道施工时安装吊架有哪8项规定

What are the 8 regulations for installing hangers during ventilation duct construction

1.根据风机,空调机组,风扇板等设备的支架和吊架的设计要求,设置隔振器,济南通风管道的其品种和规格应符合设计和产品技术文件的要求。

According to the design requirements of the brackets and hangers for equipment such as fans, air conditioning units, and fan boards, vibration isolators should be installed. The variety and specifications of Jinan ventilation ducts should meet the requirements of the design and product technical documents.

2.风道应垂直安装,间距不超过4米。单根直管应少有两个固定点。

2. The air duct should be installed vertically with a spacing of no more than 4 meters. A single straight pipe should have at least two fixing points.

3.吊架的螺孔应加工,吊杆应笔直,线头完整光滑。

3. The screw holes of the suspension bracket should be machined, the suspension rod should be straight, and the thread head should be complete and smooth.

4.对于长度超过20米的水平悬挂风道,在通风管道施工期间少应设置一个防摇支架。

For horizontal suspended air ducts with a length exceeding 20 meters, at least one anti shake bracket should be installed during the construction of the ventilation duct.

5,支架和吊架不应设置在风口,阀门,检查门和自动控制机构中,与风口或插头连接的距离不应小于200mm。

5. Brackets and hangers should not be installed in air vents, valves, inspection doors, and automatic control mechanisms, and the distance connected to air vents or plugs should not be less than 200mm.

6,当水平悬挂主干管和干空气管道长度超过20m时,应设置防止摆动的固定点,每个系统应不小于1。

When the length of the horizontally suspended main pipe and dry air pipeline exceeds 20m, fixed points to prevent swinging should be set up, and each system should not be less than 1.

7,蒸汽水管应按标准图纸和规格及规格形式选择适合的强度和刚度,济南通风管道的直径或长度超过2500㎜超宽,超重专用风管分支,吊架应在规定的设计。

7. Steam water pipes should be selected with appropriate strength and stiffness according to standard drawings, specifications, and forms of specifications. The diameter or length of Jinan ventilation pipes should exceed 2500mm for ultra wide, overweight specialized air duct branches, and hangers should be designed according to regulations.

8.安装后,每个辅助支架和吊架的应力应均匀,无明显变形。空气管道或空调设备使用的可调隔振支架和吊架的拉伸或压缩量应根据设计要求进行调整。

8. After installation, the stress on each auxiliary bracket and hanger should be uniform without significant deformation. The tension or compression of adjustable vibration isolation brackets and hangers used in air ducts or air conditioning equipment should be adjusted according to design requirements.
