| 中文摘要: |
| 目的 在自行改进的FR300ELS型机组式凹版印刷机的冷却辊（喷淋式冷却辊）装置基础上，分别对传统式和喷淋式2种冷却辊的冷却性能进行温度分布的对比分析，研究喷淋式冷却辊的结构和性能优势。方法 建立新旧2种冷却辊的MRF模型，利用CFD对冷却辊表面、轴向、周向的温度场分布进行仿真分析。结果 得到了新旧2种冷却辊在印刷机稳定工作状态下的温度分布散点图及云图。结论 喷淋式冷却辊与传统式冷却辊相比，它的温度分布更均匀、冷却效果更好、冷却效率更高。 |
| 英文摘要: |
| The work aims to conduct respective contrastive analysis on the temperature distribution of cooling performance of traditional and spray type cooling rollers based on the cooling roller (spray type cooling roller) of the self-improved FR300ELS unit type gravure printing machine, so as to research the structure and performance advantages of the spray type cooling roller. The MRF models of the new and the old cooling rollers were established. CFD was used to simulate the temperature field distribution on the surface, axial direction and circumferential direction of the cooling roller, and the scatter plot and cloud plot of the temperature distribution of these two cooling rollers were obtained when the printing machine was stably working. In conclusion, compared to a traditional cooling roller, the spray type cooling roller has a more uniform temperature distribution, a better cooling effect and a higher cooling efficiency. |
