| 中文摘要: |
| 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 kW·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. |
