山東通風(fēng)管道安裝時(shí)要注意什么

發(fā)布人：http://www.hkcts.com.cn   發(fā)布時(shí)間：2019-04-08 18:03:18

　　1、通風(fēng)管道在運(yùn)輸過(guò)程應(yīng)有防止損傷風(fēng)管的保護(hù)措施。

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

　　2、榫接風(fēng)管的連接在榫口處涂膠粘劑，是為增強(qiáng)接頭處的強(qiáng)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(dāng)風(fēng)管采用地面預(yù)組裝后架空安裝時(shí)，限制預(yù)組裝的長(zhǎng)度是為了遮免風(fēng)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(fēng)管端口為切割面時(shí)，在裝配法蘭連接件前應(yīng)將管端切口面用膠帶或膠液進(jìn)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(fēng)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(fēng)管道垂直安裝，由于空間少，又不便于以后檢修，故風(fēng)管一般采用外套角鋼法蘭連接以增加連接點(diǎn)的牢固程度和強(qiáng)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(fēng)管安裝加工是將法蘭的槽口套插在風(fēng)管管板的端頭，用膠粘劑粘接。如果其間沒(méi)有過(guò)盈量，槽口和風(fēng)管端面插入時(shí)會(huì)有一定的間隙，使其無(wú)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(fēng)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(zhǔn)備工作

　　1. Preparing for construction

　　俗話說(shuō)“磨刀不誤砍柴工”，充分的準(zhǔn)備工作是確保風(fēng)管安裝質(zhì)量的前提。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，并擁有符合條件的采光和照明條件。除此外，還要對(duì)制作好的方管進(jìn)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(fēng)管材質(zhì)的選擇

　　2. Selection of Air Pipe Material

　　風(fēng)管材質(zhì)的選擇，對(duì)風(fēng)管的施工質(zhì)量也有很大的影響。一般而言為了保證風(fēng)管的重量，需采用較小板厚的風(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。從設(shè)計(jì)角度來(lái)看，值得注意的是一個(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。

　　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(fēng)管的橫向連接

　　3. Horizontal connection of air duct

　　風(fēng)管的橫向連接有一定講究，這種連接方式可以說(shuō)是是延續(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。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(fēng)管的縱向縫接合

　　4. Longitudinal seam 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。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，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(fēng)管縱向縫接合都采用了扣式咬口。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。

　　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(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?？蓪⒐芸谟盟芰喜嫉让芊獠牧戏庾?，然后將風(fēng)管分門別類堆放好。在使用風(fēng)管前，要注意進(jìn)行徹底的清洗工作，確定板材表面無(wú)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.
