In the ventilation and cooling project of workshop, the processing and installation of ventilation duct of environmental protection air conditioner is a very important link. There are some specific requirements and specifications for the processing and installation methods of ventilation pipes, which should be studied and studied by all individuals or enterprises processing ventilation pipes and undertaking ventilation and cooling projects. What are the processing specifications of ventilation pipes? Next, Xiaobian will give you an answer. Come and understand it.

通風(fēng)管道加工前的注意情況：

Precautions before ventilation pipe processing:

其一：規(guī)格。這里所說(shuō)的規(guī)格，就是通風(fēng)管道的基本規(guī)格，我們所需要的通風(fēng)管道的尺寸和大小。值得我們注意的是，在進(jìn)行規(guī)格確定的時(shí)候，我們需要與空調(diào)的使用進(jìn)行聯(lián)系，只有這樣，我們才能夠保證通風(fēng)管道規(guī)格設(shè)定之后，能夠與空調(diào)相互連接，并發(fā)揮使用功能，完成它們的使用效果。

First: specifications. The specifications mentioned here are the basic specifications of the ventilation duct, and the size and size of the ventilation duct we need. It is worth noting that when determining the specification, we need to contact the use of air conditioner. Only in this way can we ensure that after the specification of ventilation duct is set, it can be connected with air conditioner, give play to the use function and complete their use effect.

其二：類(lèi)型。通風(fēng)管道的類(lèi)型有很多種，不同的類(lèi)型與空調(diào)進(jìn)行聯(lián)合使用，所發(fā)揮出來(lái)的效果也不一樣，尤其是保溫性的通風(fēng)管道。所以說(shuō)，我們要想進(jìn)行通風(fēng)管道加工，且讓它們更好的結(jié)合空調(diào)進(jìn)行工作，那么，我們也要在加工之前考慮下它們的類(lèi)型，這是我們確保它們作業(yè)，發(fā)揮優(yōu)勢(shì)作用的好條件。

Second: type. There are many types of ventilation pipes. Different types are used in combination with air conditioning, and the effect is also different, especially the thermal insulation ventilation pipe. Therefore, if we want to process ventilation ducts and make them work better in combination with air conditioners, we should also consider their types before processing, which is a good condition for us to ensure their efficient operation and give full play to their advantages.

綜上情況來(lái)說(shuō)，通風(fēng)管道加工前，要與空調(diào)的基本情況相結(jié)合，并要注意通風(fēng)管道的規(guī)格和類(lèi)型，不同的空調(diào)需要不同的通風(fēng)管道，規(guī)格不同，類(lèi)型也不相同。所以在加工通風(fēng)管道的時(shí)候，需要多考慮以上情況。

To sum up, before processing, the ventilation duct should be combined with the basic situation of the air conditioner, and pay attention to the specification and type of the ventilation duct. Different air conditioners need different ventilation ducts with different specifications and types. Therefore, the above situations need to be considered when processing ventilation pipes.

通風(fēng)管道加工規(guī)范：

Ventilation duct processing specification:

1、通風(fēng)管道加工時(shí)為保證風(fēng)管制作后的強(qiáng)度，在下料時(shí)粘合處有一邊要保留20mm鋁箔做護(hù)邊；

1. During the processing of ventilation duct, in order to ensure the strength of the duct after fabrication, 20mm aluminum foil shall be reserved at one side of the bonding position during blanking;

2、風(fēng)管在粘合前需預(yù)組合，檢查拼接縫處是否嚴(yán)密，尺寸是否符合要求。根據(jù)季節(jié)溫度、濕度及膠粘劑的性能確定粘合時(shí)間。粘接后，用角尺、鋼卷尺檢查、調(diào)整垂直度及對(duì)角線(xiàn)偏差應(yīng)符合規(guī)定。

2. The air duct shall be pre assembled before bonding. Check whether the splicing joint is tight and whether the size meets the requirements. The best bonding time is determined according to the seasonal temperature, humidity and the performance of the adhesive. After bonding, check and adjust the perpendicularity and diagonal deviation with angle ruler and steel tape to meet the requirements.

3、在通風(fēng)管道加工時(shí)，做好現(xiàn)場(chǎng)板材和預(yù)制管的成品保護(hù)工作。

3. During the processing of ventilation pipes, the finished products of on-site plates and prefabricated pipes shall be protected.

4、連接和安裝后，應(yīng)檢查粘接縫，在粘接后應(yīng)平整，不得有歪斜。錯(cuò)位、局部開(kāi)裂，以及2mm以上的縫隙等缺陷。

4. After connection and installation, the bonding joint shall be checked. After bonding, it shall be flat without skew. Dislocation, local cracking, and cracks above 2mm.

5、風(fēng)管支吊架間距應(yīng)符合規(guī)定。

5. The spacing between air duct supports and hangers shall meet the requirements.
