Wood processing pneumatic dust extraction pipe system is calculated by employing the equivalent hole mothod. 采用当量孔口法进行气力除尘管路系统的设计计算。
Calculation Programming for Wood Processing Pneumatic Dust Extraction Pipe System with the Equivalent Hole Method 木材加工除尘系统当量孔口法计算程序设计
We apply the program to the pneumatic dust removal pipe system of a real wood processing workshop. The result shows that the program has high calculating speed and high precision, and can raise the working efficiency of the dust removal pipe system. 将该计算程序编为1个主程序、8个子程序,应用于木工车间除尘系统的设计计算,可提高计算速度和精度,提高气力除尘管路系统的工作效率。
