　　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)在計算空氣管的長度,線的長度作為標準,包括彎管的長度、三通、變徑管、圓和地點,等等,但不包括通風的位置的長度組件(如空氣閥,空氣出口,等等),空氣管的直徑和周長應當根據風道的規模擴大。

　　(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)標準件和非標準件按成品重量計算。

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

　　(3)風道根據不同規格的圖進行面積擴大計算，濟南風道加工廠家建議檢查孔、測量孔、送風口、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、薄鋼風道

　　2. Thin steel air duct

　　(1)風道導葉按葉片面積計算。

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

　　(2)風管配件(軟接頭除外，按平方米計算)、檢驗孔、測量孔等按不同類型和規格計算。

　　(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)計算空氣管的長度時,線的長度為準,包括彎頭等管件的長度,三通,錐形管,圓的天空和地點,等等,但通風的位置的長度組件(如空氣閥和風口)不應包括在內。濟南通風管道加工廠稱，管道的直徑和周長根據圖紙的尺寸而定。但是，咬口風道的接口和翻邊量不能在擴展區域內計算。

　　(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)風管的膨脹面積按不同規格計算，不扣除風管上的檢查孔、測量孔、送風口、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.導葉計算

　　3. Guide vane calculation

　　導流葉片的作用:它是由空調主機通過交換冷氣，沿風道從出口排出，達到調節室內空氣的目的。煙管安裝廠表示，當冷空氣通過風管彎頭時，如果不將其導流，勢必會產生渦流影響冷空氣傳導!

　　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，風管彎頭建議安裝在導葉上!經常有一些人忽略了導葉的計算，或估計很不準確。計算清單如下:

　　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)根據風道短邊的尺寸，根據長邊的尺寸，選擇單側偏導葉片的數量×選擇的偏導葉片。

　　(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=本規范風道導葉的總面積。

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

　　根據驗收規范，當平面寬度大于或等于500mm時應設置導葉，故以上兩種情況應計算導葉工程量。

　　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

　　風道的計算規則與薄鋼風道相同。

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

　　這里介紹濟南通風管道數量計算的四條規則，相信大家閱讀這些內容后對其理解會更近一步，希望這些內容能對大家有所幫助，更多的細節能讓大家更加關注網站的動態。

　　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.
