　　1、通風管道在運輸過程應(yīng)有防止損傷風管的保護措施。

　　1. Ventilation pipes should be protected against damage during transportation.

　　2、榫接風管的連接在榫口處涂膠粘劑，是為增強接頭處的強度。

　　2. The connection of tenon-joint air duct is coated with adhesive at the tenon-joint to enhance the strength of the joint.

　　3、當風管采用地面預(yù)組裝后架空安裝時，限制預(yù)組裝的長度是為了遮免風管因自重產(chǎn)生的彎曲而破壞構(gòu)件接口。

　　3. When air ducts are installed overhead after ground pre-assembly, the length of pre-assembly is limited in order to prevent the bending of air ducts caused by self-weight from destroying component interfaces.

　　4、玻璃纖維復(fù)合板風管端口為切割面時，在裝配法蘭連接件前應(yīng)將管端切口面用膠帶或膠液進行封堵，才能防止玻璃纖維外露和飛散。

　　4. When the end of glass fiber composite board air duct is cut face, before assembling flange connector, the end of the pipe should be sealed with tape or glue to prevent the glass fiber from exposing and flying away.

　　5、非法蘭連接的玻璃纖維復(fù)合板風管垂直安裝的支撐件制作與安裝的方法。

　　5. The method of making and installing the supporting parts for the vertical installation of the glass fibre composite board air duct connected by illegal blue.

　　6、豎井內(nèi)通風管道垂直安裝，由于空間少，又不便于以后檢修，故風管一般采用外套角鋼法蘭連接以增加連接點的牢固程度和強度，并把法蘭作成“井”形，吊筋直接吊在角鋼法蘭的吊耳上而不另設(shè)支撐件。

　　6. Vertical installation of ventilation pipes in vertical shaft, due to the lack of space and the inconvenience of later maintenance, so the air duct generally adopts the outer angle steel flange connection to increase the firmness and strength of the connection points, and the flange is made into a "well" shape, and the suspension bar is directly suspended on the lifting lug of the angle steel flange without additional supporting parts.

　　風管安裝加工是將法蘭的槽口套插在風管管板的端頭，用膠粘劑粘接。如果其間沒有過盈量，槽口和風管端面插入時會有一定的間隙，使其無法粘為一體。

　　The installation and processing of the air duct is to insert the slot sleeve of the flange into the end of the air duct plate, and to bond it with adhesive. If there is no interference between them, there will be some gap between the groove and the end face of the air duct when inserting, which makes it impossible to stick together.

　　通風設(shè)備的安裝質(zhì)量更是影響到空氣的交換

　　The installation quality of ventilation equipment affects air exchange.

　　1、做好施工前的準備工作

　　1. Preparing for construction

　　俗話說“磨刀不誤砍柴工”，充分的準備工作是確保風管安裝質(zhì)量的前提。在準備凈化風管的制作時，無論是采取工廠集中制作還是現(xiàn)場制作方式，都必須保證場地的潔凈和封閉，并擁有符合條件的采光和照明條件。除此外，還要對制作好的方管進行看管，盡量避免污染。

　　As the saying goes, "no mistake in cutting firewood by sharpening knives", adequate preparation is the premise to ensure the installation quality of air ducts. When preparing for the production of purified air ducts, whether centralized production in factories or on-site production, it is necessary to ensure that the site is clean and closed, and has the lighting and lighting conditions that meet the requirements. In addition, we should also take care of the square tubes made to avoid pollution as far as possible.

　　2、風管材質(zhì)的選擇

　　2. Selection of Air Pipe Material

　　風管材質(zhì)的選擇，對風管的施工質(zhì)量也有很大的影響。一般而言為了保證風管的重量，需采用較小板厚的風管，但除此外還需要綜合考慮風管的尺寸和壓力級別。從設(shè)計角度來看，值得注意的是一個系統(tǒng)可以同時存在幾種對應(yīng)于不同靜壓級別的風管板厚。

　　The selection of air duct material also has a great influence on the construction quality of air duct. Generally speaking, in order to ensure the weight of the duct, the minimum thickness of the duct is needed, but in addition, the size and pressure level of the duct need to be considered comprehensively. From the design point of view, it is worth noting that there are several duct sheet thicknesses corresponding to different static pressure levels in a system at the same time.

　　3、風管的橫向連接

　　3. Horizontal connection of air duct

　　風管的橫向連接有一定講究，這種連接方式可以說是是延續(xù)風管長度的一種手段，還具備增強剛度及保持風管精確地橫向尺寸的作用。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。

　　The horizontal connection of air duct is particular. It can be said that this connection is a means to extend the length of air duct. It also has the function of enhancing stiffness and keeping accurate lateral dimension of air duct. Usually the way of lateral connection is angle steel flange connection, which depends on the thickness of the wall, but also depends on the type of connection and the way of plate wall reinforcement.

　　4、風管的縱向縫接合

　　4. Longitudinal seam joint of air duct

　　風管的縱向縫接合方式可以根據(jù)實際情況，選擇對應(yīng)的方式。在中、低壓風管中常常使用扣式咬口連接，對于矩形風管，聯(lián)合咬口使用無任何壓力級別，因此使用扣式咬口可以節(jié)省一道翻邊工序，目前大多數(shù)的風管縱向縫接合都采用了扣式咬口。對于立縫和封蓋式立縫可以使用鉚釘、自攻螺絲、點焊、壓凸凹痕等方法緊固。

　　The longitudinal joint mode of air duct can be selected according to the actual situation. Button bite connection is often used in middle and low pressure air ducts. For rectangular air ducts, there is no pressure level for joint bite. Therefore, using buckle bite can save a flanging process. At present, buckle bite is used in most longitudinal seam joints of air ducts. Rivets, tapping screw, spot welding and indentation can be used to fasten the vertical seam and capping vertical seam.

　　5、風管的存放

　　5. Storage of air ducts

　　預(yù)制好的風管，是必須要做好存放工作，以免受到二次污染。可將管口用塑料布等密封材料封住，然后將風管分門別類堆放好。在使用風管前，要注意進行徹底的清洗工作，確定板材表面無腐蝕，干燥后不吸塵。

　　Prefabricated air ducts must be stored well to avoid secondary pollution. The nozzle can be sealed with plastic cloth and other sealing materials, and then the air ducts can be stacked in different categories. Before using the air duct, we should pay attention to thorough cleaning work to ensure that there is no corrosion on the surface of the sheet and no dust absorption after drying.
