| 摘 要： | 电液比例控制系统在快锻液压机中的应用日益广泛.提出采用三通插装阀的新型电液比例控制系统的方案,建立其数学模型和仿真模型并与单独设置高压卸荷阀的控制系统进行对比.结果表明:系统用三通比例插装阀控制,无需单独设置高压卸荷阀,控制性能更好,并用蓄能器作辅助动力源,起到节约制造成本和节能的效果.

| Abstract: | Electro-hydraulic proportional control system was widely used in fast forging hydraulic press.The new electro-hydraulic proportional control system by using three-way cartridge valve was presented,and its mathematical model and simulation model were built.The new control system was compared with control system mount of high pressure unloading valve separately.The results show that control performance is even better for system controlled by three-way cartridge valve,without mount of high pressure unloading v... |
