摘要
为了获得不同气流输送方式对铝箔剪切机碎屑收集装置工作效率的影响规律,针对送风式与吸风式两种管路模型,使用计算流体动力学方法计算不同管路结构时的压力-速度耦合流场,分析了不同流动现象与管路结构的对应关系。数值计算结果表明,在等距管路中,送风式与吸风式收集装置均可满足铝箔碎屑收集时支管吸力均匀的要求;吸风式收集装置支管负压值为送风式的4.75倍,速度为2.18倍,负压利用率更高,但整体结构更复杂、成本更高。
To obtain the efficiency of different air applying methods during the routine work of the foil scrap collection,the supply and suction pipe structures are generated and the pressure-velocity coupled flow fields are simulated using CFD method.The deep corresponding relationship between flow phenomenon and physical structure is studied in detail and the numerical results show that there is nearly same negative pressure in two branch pipes when using both the supply and suction structures.For the suction pipes,the pressure and velocity values are respectively 4.75 times and 2.18 times that of air apply pipes,which means higher negative pressure utilization.While the suction device has the weakness of more complex models and higher cost.
