摘要

摘要: 为了提高油墨预置精度,优化墨键结构,并依此精确控制输出墨量,对墨斗系统在不同条件下油墨运动流场建立数学模型和仿真计算,分析了油墨出口处油墨的流动速度分布情况,并对墨斗辊变转速、墨键变开度条件下墨斗流场的速度和压力的变化规律以及与油墨流量的关系进行了阐述。结果证明该方法能更准确地确定墨键开度、墨辊转速和墨量的关系。

Abstract: In order to improve the accuracy of ink preset and optimize the structure of the ink key,the mathematical model of the ink flow fields with different parameters conditions is established. Numerical simulations are performed to obtian the velocity distribution of flow fields at ink key opening side. And the variation law of fountain flow velocity and pressure is analyzed under the condition of variable speed and opening degree. The results show that the relationship among ink key opening degree,ink roller speed and the flow rate of ink can be accurately determined. This study can provide theoretical basis for the accurate control of ink flow during actual work.
