基于测试的凹印机能效分析

Energy Efficiency Analysis of Gravure Press Based on Energy Consumption Test

目的为印刷机械的改进和节能减排提供基础数据。方法使用风量计量法对多家印刷厂不同型号凹印机的能耗相关参数进行测量和计算,并对测量数据进行差异分析。结果得出了不同加热方式的凹印机在正常印刷时各部分的能耗量,以及凹印机总的能源利用率。结论提出了一种以单位平方米印品实地印刷消耗的能源量作为评价凹印机能效的指标。通过对部分机型的热量使用效率,以及部分电机的工作状况及效率进行分析,找到了凹印机耗能的重点,以及影响凹印机能源消耗的可能因素,并对凹印机的节能方法进行了初步探究。

Objective To provide basic data for the improvement and energy conservation of printing machinery. Methods The relevant parameters of energy consumption of different models of gravure press in several printing companies were measured and analyzed using air flow measurement method, and the data was subjected to variance analysis. Results The amount of energy consumption and the total energy efficiency when the gravure press was printing in different heating ways were obtained. Conclusion The amount of energy consumed per unit square meter of printed matter was proposed as an evaluation index for gravure press energy efficiency. Through analysis of the heat efficiency of some print machines and the working conditions and efficiency of some motors, the focus of energy consumption in gravure press as well as the possible influencing factors of energy consumption in gravure press were found, and a preliminary exploration was conducted on the energy-saving method of gravure press.
