We provide you with comprehensive services. We will gradually contribute more knowledge to you. Please stay tuned. When installing air ducts, you need to consider their size and area. The calculation of duct area is as follows: 1. The formula for calculating duct area is: circular duct F=π× D × L, where F - the unfolded area of the circular duct (in m2); D-diameter of circular air duct; L - Length of the centerline of the pipeline. Calculate by multiplying the circumference of a rectangular duct by the length of the centerline of the duct. The calculation rule for the surface area of ventilation duct elbows is to extend the duct to the intersecting centerline.

　　2、三(san)(san)通(tong)：風管長(chang)(chang)度(du)以中心線長(chang)(chang)度(du)為(wei)(wei)準(zhun)(主(zhu)管與支管以其中心線交點劃分(fen))，包括彎頭、三(san)(san)通(tong)、變徑管、天圓地方等(deng)管件的長(chang)(chang)度(du)，但不(bu)得包括部(bu)(bu)件所(suo)占長(chang)(chang)度(du)。直(zhi)徑和周長(chang)(chang)按圖(tu)示(shi)尺寸為(wei)(wei)準(zhun)展開(kai)，咬(yao)口(kou)重疊部(bu)(bu)分(fen)已包括在(zai)定額內，不(bu)得另(ling)行增加。

　　2. Three way: The length of the air duct is based on the centerline length (the main and branch pipes are divided by the intersection of their centerlines), including the length of elbows, tees, reducers, and other fittings, but not including the length occupied by the components. The diameter and circumference shall be unfolded according to the dimensions shown in the diagram, and the overlapping part of the bite is already included in the quota and cannot be increased separately.

　　通風管道安(an)裝(zhuang)注意事(shi)項

　　Precautions for installation of ventilation ducts

　　1、風(feng)(feng)管和風(feng)(feng)機連(lian)接(jie)(jie)時，先(xian)要在進(jin)出(chu)風(feng)(feng)口加上(shang)(shang)一個軟接(jie)(jie)頭(tou)(tou)，而(er)且(qie)(qie)它(ta)的斷面尺寸要跟風(feng)(feng)機進(jin)出(chu)風(feng)(feng)口一樣的，軟管接(jie)(jie)頭(tou)(tou)可以用(yong)帆(fan)布(bu)材(cai)料(liao)，而(er)且(qie)(qie)它(ta)的長度為200以上(shang)(shang)，松(song)緊度也是要合適(shi)才(cai)行。

　　1. When connecting the air duct and fan, a flexible joint should be added at the inlet and outlet, and its cross-sectional size should be the same as that of the fan inlet and outlet. The hose joint can be made of canvas material, and its length should be over 200 with appropriate tightness.

　　2、風道和(he)除塵的(de)設備在連接前(qian)，也是要等這個設備安(an)裝(zhuang)好后，實際上會(hui)對圖紙預制及安(an)裝(zhuang)。

　　2. Before connecting the air duct and dust removal equipment, it is also necessary to wait for the equipment to be installed, and in fact, the drawings will be prefabricated and installed.

　　3、在(zai)(zai)安裝(zhuang)(zhuang)風(feng)道(dao)進和出風(feng)口時(shi)，要在(zai)(zai)風(feng)道(dao)預制時(shi)對它開(kai)出洞，在(zai)(zai)將它裝(zhuang)(zhuang)完后的(de)風(feng)道(dao)定要連接緊(jin)密。

　　3. When installing the air inlet and outlet of the air duct, holes should be drilled during the prefabrication of the air duct, and the air duct after installation must be tightly connected.

　　4、輸(shu)送(song)含濕(shi)量比較(jiao)大時，管道也是需要(yao)設坡度，低(di)點(dian)處要(yao)根(gen)據排水(shui)管進行連接，注意安裝中，風(feng)道底部(bu)不能出(chu)現(xian)一(yi)個(ge)縱向(xiang)接縫(feng)，如果是接縫(feng)處一(yi)定要(yao)密(mi)封處理(li)。

　　4. When conveying high moisture content, the pipeline also needs to have a slope, and the low point should be connected according to the drainage pipe. During installation, it is important not to have a longitudinal joint at the bottom of the air duct. If it is a joint, it must be sealed.

　　5、輸送易(yi)燃的鋼板風道，在連(lian)(lian)接(jie)(jie)處也是要安裝(zhuang)上跨接(jie)(jie)線，并且還要連(lian)(lian)接(jie)(jie)靜電接(jie)(jie)地網。

　　5. When transporting flammable steel plate air ducts, jumper wires should also be installed at the connection points, and static grounding grids should be connected.

　　6、當(dang)水平風道達(da)到(dao)了4m以上時(shi)，那么(me)安裝人(ren)員就(jiu)要提前到(dao)帶綁上，腳(jiao)手架也(ye)是在把它(ta)跳(tiao)板固定好，寬度一定要符合規范才行，防止工(gong)具等物掉落砸傷人(ren)。

　　6. When the horizontal air duct reaches more than 4m, the installation personnel should tie up the safety belt in advance, and the scaffold should also fix its springboard. The width must comply with safety regulations to prevent tools and other objects from falling and injuring people.
