摘要
目的研究印刷机输墨系统中串墨辊在定常状态下表面温度的分布情况。方法利用Pro/E对现有墨辊结构进行了三维建模,使用FLUENT仿真定常状态下串墨辊内部流体状况,得到了墨辊表面温度分布云图。结果得到现有结构墨辊表面温度集中在23.6℃左右,温差为1.1℃,根据分析结果对现有结构进行优化,得到优化后的墨辊表面温度主要集中在22.87℃左右。结论新结构可使一台印刷机每年节省电量12 776 k W·h,新型串墨辊结构相比内套辊式墨辊冷却结构,更能满足当今企业追求的绿色环保的需求。
The experiment aimed to study the string roller＇ s surface temperature distribution under steady state of the press inking system. Pro/E was used to model the three-dimensional of existing roller structure. FLUENT was used to simulate the string roller＇ s internal fluid situation under the steady conditions. Thus, the ink roller＇ s surface temperature contour was obtained. The results showed that the existing structure＇ s surface temperature was concentrated around 23.6℃, the temperature difference was 1.1℃. The optimized roller surface temperature was mainly concentrated around 22.87℃ after optimization and improvement of the existing roller according to the analysis. The new structure can save an electricity of 12 776 kW·h per year for a printer. Therefore, the new string roller structure can better meet the need of enterprises nowadays to pursue green environmental protection than the existing cooling structure of inner sleeve roller.
