    完結通風管道加工的阻力平衡的有效方法

    一、要害詞的界說

    1、 Definition of Key Words

    節點的編號規則.為了能依據各節點間的邏輯關系,便當地查尋風道體系的各個環路,咱們給各個節點一個數字編號,并對節點編號作如下假定:按風量遞減方向對節點從小到大編號,或都說關于送風體系則節點編號沿氣流方向遞加

    The numbering rules for nodes. In order to easily search for the various loops of the air duct system based on the logical relationship between each node, we give each node a numerical number and make the following assumption for node numbering: number nodes from small to large in the direction of decreasing air volume, or for air supply systems, node numbering increases along the direction of air flow

    二、通風管道體系各環路的主動排序

    2、 Active sorting of each loop in the ventilation duct system

    通風管道體系各環路的主動排序是完結阻力平衡主動核算的條件,也是本程序的要害進程之一.其進程實踐上便是依照各環路的阻力丟掉巨細進行主動排序的進程.通過排序能夠較好的處理如下兩個問題:①能夠依據排序效果直接選取體系的Z倒霉環路;②確實削減各環路阻力平衡時的重復核算

    The active sorting of each loop in the ventilation duct system is a condition for achieving resistance balance and active calculation, and it is also one of the key processes of this program. In practice, the process is to actively sort the resistance of each loop according to its size. Sorting can effectively handle the following two problems: ① selecting the Z unlucky loop of the system directly based on the sorting effect; ② Indeed, reducing the redundant calculation of resistance balance in each loop

    體系各環路的主動排序的詳細履行進程如下:①主動選取結尾節點;②依次搜索每一個結尾節點對應的環路途徑并同步核算其阻力丟掉值;③按阻力丟掉值從大到小對一切環路進行擺放

    The detailed implementation process of the active sorting of each loop in the system is as follows: ① Actively selecting the ending node; ② Search sequentially for the loop path corresponding to each ending node and synchronously calculate its resistance loss value; ③ Arrange all loops in descending order of resistance drop values

    三、各環路的阻力平衡

    3、 Resistance balance of each loop

    阻力平衡是整個風管規劃進程中Z煩瑣,也是Z要害的一步.在此選用按環路阻力值從大到小的次序依次對各環路進行平衡,并對業已進過平衡的管段不再進行調整,可較好的處理平衡進程中的重復核算問題.為了便于核算,咱們假設風管支路中需調整的各管段其調整前后阻力值份額堅持不變,而調整前后管徑與阻力值之間的關系為

    Resistance balance is a tedious and crucial step in the entire process of air duct planning. Here, we choose to balance each loop in descending order of resistance values, and no longer adjust the sections that have already been balanced, which can better handle the problem of repeated accounting in the balance process. For the sake of accounting, we assume that the resistance value share of each section in the air duct branch that needs to be adjusted remains unchanged before and after adjustment, The relationship between the diameter of the pipe before and after adjustment and the resistance value is

    阻力平衡前后風管支路的管徑;p、p:阻力平衡前后Z倒霉環路上對應風管支路的阻力值

    The diameter of the air duct branch before and after resistance balance; p. P: Resistance value of the corresponding air duct branch on the Z unlucky loop before and after resistance balance

    阻力平衡主動核算時,將環路中現已調整的管段途徑及阻力丟掉值除掉,并對未經調整的支路按式中對各管段核算出經阻力平衡后的管徑d,由d核算出對應的速度v及管段阻力δ

    When actively calculating resistance balance, the already adjusted pipeline routes and resistance drop values in the loop are removed, and for the unadjusted branch, the diameter d of each pipeline segment after resistance balance is calculated according to the formula, and the corresponding velocity v and pipeline resistance are calculated based on d δ
