對(duì)于城市各類建筑來(lái)說(shuō)，山東通風(fēng)管道工程起著至關(guān)重要的作用，通風(fēng)管道的質(zhì)量將直接影響到整個(gè)工程質(zhì)量。今天通風(fēng)管道廠家為大家介紹更好的控制通風(fēng)管道安裝質(zhì)量的方法。
For all kinds of buildings in cities, Shandong ventilation pipeline project plays a crucial role, and the quality of ventilation pipeline will directly affect the quality of the whole project. Today, the ventilation pipe manufacturer introduces the better control method of the installation quality of the ventilation pipe.
山東通風(fēng)管道
Shandong ventilation pipeline
一、施工前的準(zhǔn)備工作
1、 Preparation before construction
充分的準(zhǔn)備工作是確保風(fēng)管安裝質(zhì)量的前提。
Adequate preparation is the premise to ensure the installation quality of air duct.
在準(zhǔn)備凈化風(fēng)管的制作時(shí)，無(wú)論是采取工廠集中制作還是現(xiàn)場(chǎng)制作方式，都必須保證場(chǎng)地的潔凈和封閉。
When preparing the production of the purification air duct, whether it is centralized production in the factory or on-site production, the site must be clean and closed.
擁有符合條件的采光和照明條件。
Have qualified lighting and lighting conditions.
除此外，還要對(duì)制作好的方管進(jìn)行管理，避免管道被污染。
In addition, we should also manage the square pipes to avoid the pipeline being polluted.
二、風(fēng)管的橫向連接
2、 Transverse connection of air duct
風(fēng)管的橫向連接是延續(xù)風(fēng)管長(zhǎng)度的一種手段，還具備增強(qiáng)剛度及保持風(fēng)管精確地橫向尺寸的作用。
The transverse connection of the duct is a means to continue the length of the duct, and also has the function of enhancing the rigidity and keeping the wind duct accurately in the transverse dimension.
通常橫向連接的方式是角鋼法蘭連接，這種連接方式取決于壁厚，更取決于連接種類及板壁加固方式。
Generally, the transverse connection is angle steel flange connection, which depends on the wall thickness, and more depends on the type of connection and the reinforcement of the plate wall.
三、風(fēng)管材質(zhì)的選擇
3、 Selection of duct material
為了保證風(fēng)管的重量，需采用小板厚的風(fēng)管，但除此外還需要綜合考慮風(fēng)管的尺寸和壓力級(jí)別。
In order to ensure the weight of the duct, the small plate thick air duct is required, but in addition, the size and pressure level of the duct should be considered comprehensively.
從設(shè)計(jì)角度來(lái)看，一個(gè)系統(tǒng)可以同時(shí)存在幾種對(duì)應(yīng)于不同靜壓級(jí)別的風(fēng)管板厚。
From the design point of view, there are several types of duct plate thickness corresponding to different static pressure levels simultaneously in a system.
四、風(fēng)管的縱向縫接合
4、 Longitudinal joint of air duct
風(fēng)管的縱向縫接合方式可以根據(jù)實(shí)際情況，選擇對(duì)應(yīng)的方式。
The longitudinal joint mode of air duct can be selected according to the actual situation.
在中、低壓風(fēng)管中常常使用扣式咬口連接，對(duì)于矩形風(fēng)管，聯(lián)合咬口使用無(wú)任何壓力級(jí)別。
Buckle type is often used in medium and low pressure air ducts. For rectangular air ducts, joint bite is not used for any pressure level.
對(duì)于立縫和封蓋式立縫可以使用鉚釘、自攻螺絲、點(diǎn)焊、壓凸凹痕等方法緊固。
For vertical joint and cover type vertical joint, rivets, tapping screws, spot welding, indenting and other methods can be used to fasten.
五、風(fēng)管的存放
5、 Storage of air ducts
預(yù)制好的風(fēng)管，是必須要做好存放工作，以免受到二次污染。
The prefabricated air duct must be stored well to avoid secondary pollution.
可將管口用塑料布等密封材料封住，然后將風(fēng)管分門別類堆放好。
The pipe mouth can be sealed with plastic cloth and other sealing materials, and then the air duct can be piled up in different categories.
在使用風(fēng)管前，要注意進(jìn)行的清洗工作，確定板材表面無(wú)腐蝕，干燥后不吸塵。
Before using the air duct, pay attention to the cleaning work to ensure that the surface of the plate is free of corrosion and no dust after drying.

因此，嚴(yán)格把控好山東通風(fēng)管道的安裝質(zhì)量是非常重要的。通風(fēng)管道現(xiàn)在應(yīng)用在各個(gè)領(lǐng)域，受到廣大群眾的歡迎與喜愛(ài)，想要了解更多咨詢，歡迎持續(xù)關(guān)注我們的信息。
Therefore, it is very important to control the installation quality of ventilation pipes in Shandong Province. Ventilation ducts are now used in various fields, and are welcomed and loved by the masses. For more consultation, we welcome to pay close attention to our information. 上一篇：通風(fēng)管道設(shè)計(jì)結(jié)合實(shí)際的原因!
