摘　　要：系统性地探究了挤出造粒机组在预热阶段与正常挤出阶段的能耗分布情况。结果表明,在预热环节,机筒设定温度是主导机组能耗的关键因素。在挤出环节,机筒设定温度、喂料速率和螺杆转速对挤压造粒机组的能耗分布均有较为显著的影响。为全面评估不同转速对机组能耗的影响,细分了固定喂料速率下的小范围转速调整,固定主电机工作电流下的大范围转速调整2种工况。In this paper,the energy consumption distribution of an extruder pelletizing component was systematically ex-plored during the preheating and extruding stages.The findings indicated that the barrel set temperature was a pivotal fac-tor influencing the energy consumption of the component during the preheating stage.In the normal extruding stage,the barrel set temperature,feed rate,and screw speed collectively exerted a significant impact on the energy consumption dis-tribution of the extruder pelletizing component.To evaluate the impact of different speeds on the energy consumption of the component comprehensively,two working conditions were subdivided to be a small-range speed adjustment at a fixed feed rate and a large-range speed adjustment at a fixed main motor operating current.
