为了从快锻液压机的能量源头出发降低系统的溢流损失和压力损失，提出了一种快锻液压机泵阀复合控制系统，通过相关理论对泵阀复合控制系统的节能机理进行了定性分析，通过实验定量研究了泵阀复合控制系统的能耗。实验结果表明：快锻液压机泵阀复合控制系统的能量利用率达到了31.9%，与电液比例阀控系统相比提高了近5倍，同时泵阀复合控制系统的输入功率仅为电液比例控制系统的18.4%。研究结果对提高快锻液压机的能量利用率并降低系统能耗具有重要意义。

Considering the energy source of fast forging hydraulic press,a kind of valve and pump compound control system on fast forging hydraulic press was proposed to reduce the overflow loss and pressure loss of the system.The energy-saving mechanism of valve and pump compound control sys-tem was qualitatively analyzed theoretically,and the system energy consumption was quantitatively studied by experiments.The experimental results show that energy utilization rate of valve and pump compound control system reaches 3 1.9%,and improves nearly 5 times compared with electro-hydrau-lic proportional valve control system.At the same time,the input power of valve and pump compound control system is only 1 8.4% of the proportional valve control system.The study results have impor-tant significance to improve energy utilization and reduce the energy consumption of the fast forging hydraulic press.
