　　How much do you know about the regulations on the quantities of ventilation pipes in Jinan? Don't you understand? Here is a brief introduction of the ventilation pipe processing plant, hoping to help you.

　　1. 塑料管道及部件

　　1. Plastic pipes and components

　　(1)在計(jì)算空氣管的長度,線的長度作為標(biāo)準(zhǔn),包括彎管的長度、三通、變徑管、圓和地點(diǎn),等等,但不包括通風(fēng)的位置的長度組件(如空氣閥,空氣出口,等等),空氣管的直徑和周長應(yīng)當(dāng)根據(jù)風(fēng)道的規(guī)模擴(kuò)大。

　　(1) When calculating the length of the air pipe, the length of the center line shall be taken as the standard, including the length of bends, tees, reducers, circles and locations, etc., but excluding the length components of the ventilation position (such as air valves, air outlets, etc.), the diameter and perimeter of the air pipe shall be expanded according to the scale of the air duct.

　　(2)標(biāo)準(zhǔn)件和非標(biāo)準(zhǔn)件按成品重量計(jì)算。

　　(2) Standard parts and non-standard parts are calculated according to the weight of finished products.

　　(3)風(fēng)道根據(jù)不同規(guī)格的圖進(jìn)行面積擴(kuò)大計(jì)算，濟(jì)南風(fēng)道加工廠家建議檢查孔、測量孔、送風(fēng)口、吸出口等占用的面積是否被扣除。

　　(3) The area expansion calculation of air duct shall be conducted according to the drawings of different specifications. Jinan air duct manufacturer suggests whether the area occupied by inspection hole, measuring hole, air supply outlet and suction outlet shall be deducted.

　　2、薄鋼風(fēng)道

　　2. Thin steel air duct

　　(1)風(fēng)道導(dǎo)葉按葉片面積計(jì)算。

　　(1) The air duct guide vane is calculated according to the blade area.

　　(2)風(fēng)管配件(軟接頭除外，按平方米計(jì)算)、檢驗(yàn)孔、測量孔等按不同類型和規(guī)格計(jì)算。

　　(2) Air pipe fittings (excluding soft joints, calculated by square meters), inspection holes, measurement holes, etc. shall be calculated according to different types and specifications.

　　(3)計(jì)算空氣管的長度時(shí),線的長度為準(zhǔn),包括彎頭等管件的長度,三通,錐形管,圓的天空和地點(diǎn),等等,但通風(fēng)的位置的長度組件(如空氣閥和風(fēng)口)不應(yīng)包括在內(nèi)。濟(jì)南通風(fēng)管道加工廠稱，管道的直徑和周長根據(jù)圖紙的尺寸而定。但是，咬口風(fēng)道的接口和翻邊量不能在擴(kuò)展區(qū)域內(nèi)計(jì)算。

　　(3) When calculating the length of air pipe, the length of the center line shall prevail, including the length of elbow and other pipe fittings, tee, tapered pipe, round sky and place, etc., but the length components (such as air valve and air vent) of ventilation position shall not be included. Jinan ventilation pipe processing plant said the diameter and perimeter of the pipe according to the size of the drawing. However, the interface and flanging amount of bite air duct cannot be calculated in the extended area.

　　(4)風(fēng)管的膨脹面積按不同規(guī)格計(jì)算，不扣除風(fēng)管上的檢查孔、測量孔、送風(fēng)口、吸出口所占面積。

　　(4) The expansion area of air duct shall be calculated according to different specifications, and the area of inspection hole, measurement hole, air supply outlet and suction outlet on air duct shall not be deducted.

　　3.導(dǎo)葉計(jì)算

　　3. Guide vane calculation

　　導(dǎo)流葉片的作用:它是由空調(diào)主機(jī)通過交換冷氣，沿風(fēng)道從出口排出，達(dá)到調(diào)節(jié)室內(nèi)空氣的目的。煙管安裝廠表示，當(dāng)冷空氣通過風(fēng)管彎頭時(shí)，如果不將其導(dǎo)流，勢必會產(chǎn)生渦流影響冷空氣傳導(dǎo)!

　　The function of the guide vane: it is discharged from the outlet along the air duct by the air conditioner host through the exchange of air conditioner, so as to achieve the purpose of regulating the indoor air. The smoke pipe installation plant said that when the cold air passes through the elbow of the air pipe, if it is not diverted, there will be eddy current which will affect the cold air conduction!

　　因此，風(fēng)管彎頭必須安裝在導(dǎo)葉上!經(jīng)常有一些人忽略了導(dǎo)葉的計(jì)算，或估計(jì)很不準(zhǔn)確。計(jì)算清單如下:

　　Therefore, the duct elbow must be installed on the guide vane! Often some people ignore the calculation of the guide vane, or the estimation is very inaccurate. The calculation list is as follows:

　　(1)根據(jù)風(fēng)道短邊的尺寸，根據(jù)長邊的尺寸，選擇單側(cè)偏導(dǎo)葉片的數(shù)量×選擇的偏導(dǎo)葉片。

　　(1) According to the size of the short side of the air duct and the size of the long side, select the number of single side guide vanes × selected guide vanes.

　　(2)葉片數(shù)=本規(guī)范風(fēng)道導(dǎo)葉的總面積。

　　(2) Number of blades = total area of air duct guide vane in this specification.

　　根據(jù)驗(yàn)收規(guī)范，當(dāng)平面寬度大于或等于500mm時(shí)應(yīng)設(shè)置導(dǎo)葉，故以上兩種情況應(yīng)計(jì)算導(dǎo)葉工程量。

　　According to the acceptance specification, guide vane shall be set when the plane width is greater than or equal to 500mm, so the work quantity of guide vane shall be calculated in the above two cases.

　　4. 不銹鋼管和鋁管

　　4. Stainless steel pipe and aluminum pipe

　　風(fēng)道的計(jì)算規(guī)則與薄鋼風(fēng)道相同。

　　The calculation rule of air duct is the same as that of thin steel air duct.

　　這里介紹濟(jì)南通風(fēng)管道數(shù)量計(jì)算的四條規(guī)則，相信大家閱讀這些內(nèi)容后對其理解會更近一步，希望這些內(nèi)容能對大家有所幫助，更多的細(xì)節(jié)能讓大家更加關(guān)注網(wǎng)站的動態(tài)。

　　Here are four rules for the calculation of the number of ventilation pipes in Jinan. I believe that after reading these contents, you will have a closer understanding. I hope that these contents can help you, and more details can make you pay more attention to the dynamic of the website.
