  你对济南通风管道工程量的规定了解多少?不明白了吗?下面简要介绍一下通风管道加工厂,希望对您有所帮助。
  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)在计算空气管的长度,线的长度作为标准,包括弯管的长度、三通、变径管、圆和地点,等等,但不包括通风的位置的长度组件(如空气阀,空气出口,等等),空气管的直径和周长应当根据风道的规模扩大。
  (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)标准件和非标准件按成品重量计算。
  (2) Standard parts and non-standard parts are calculated according to the weight of finished products.
  (3)风道根据不同规格的图进行面积扩大计算,济南风道加工厂家建议检查孔、测量孔、送风口、吸出口等占用的面积是否被扣除。
  (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、薄钢风道
  2. Thin steel air duct
  (1)风道导叶按叶片面积计算。
  (1) The air duct guide vane is calculated according to the blade area.
  (2)风管配件(软接头除外,按平方米计算)、检验孔、测量孔等按不同类型和规格计算。
  (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)计算空气管的长度时,线的长度为准,包括弯头等管件的长度,三通,锥形管,圆的天空和地点,等等,但通风的位置的长度组件(如空气阀和风口)不应包括在内。济南通风管道加工厂称,管道的直径和周长根据图纸的尺寸而定。但是,咬口风道的接口和翻边量不能在扩展区域内计算。
  (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)风管的膨胀面积按不同规格计算,不扣除风管上的检查孔、测量孔、送风口、吸出口所占面积。
  (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.导叶计算
  3. Guide vane calculation
  导流叶片的作用:它是由空调主机通过交换冷气,沿风道从出口排出,达到调节室内空气的目的。烟管安装厂表示,当冷空气通过风管弯头时,如果不将其导流,势必会产生涡流影响冷空气传导!
  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,风管弯头必须安装在导叶上!经常有一些人忽略了导叶的计算,或估计很不准确。计算清单如下:
  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)根据风道短边的尺寸,根据长边的尺寸,选择单侧偏导叶片的数量×选择的偏导叶片。
  (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)叶片数=本规范风道导叶的总面积。
  (2) Number of blades = total area of air duct guide vane in this specification.
  根据验收规范,当平面宽度大于或等于500mm时应设置导叶,故以上两种情况应计算导叶工程量。
  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. 不锈钢管和铝管
  4. Stainless steel pipe and aluminum pipe
  风道的计算规则与薄钢风道相同。
  The calculation rule of air duct is the same as that of thin steel air duct.
  这里介绍济南通风管道数量计算的四条规则,相信大家阅读这些内容后对其理解会更近一步,希望这些内容能对大家有所帮助,更多的细节能让大家更加关注网站的动态。
  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.
