摘　　要：根据快速锻造液压机工作过程中的能量需求特性,提出了一种新型能量供给方式,即叠加供液节能技术。采用蓄能器进行中低压储能,在液压机的一个工作循环中,直接利用低压充液罐或高位油箱为快下行程充液,在变形压力较小时利用蓄能器为加压行程提供中低压成形压力,在变形压力较大时利用增压器提供高压成形压力,这3个过程由液压及控制系统进行平稳连贯过渡。其次,对叠加供液的相关原理进行了详述,并介绍了采用叠加供液节能技术的35 MN快速锻造液压机液压工作原理。该技术已在实际生产中成功应用,且在不降低技术指标的前提下,装机功率低于目前标准机组的1/3,标准机组空载损耗的电量即能满足该机组的正常运行,节能效果明显且成本低。According to the characteristics of energy demand in the working process of fast forging hydraulic press,a new energy supply method,namely,the superimposed liquid supply energy-saving technology,was proposed.This technology used an accumulator for medium and low-pressure energy storage,and in a working cycle of the hydraulic press,a low-pressure liquid filling tank or a high-level oil tank was directly used to fill the liquid for the fast-down stroke.When the deformation pressure was small,the accumulator was used to provide medium and low-pressure forming pressure for the pressurizing stroke,and when the deformation pressure was larger,the supercharger was used to provide high-pressure forming pressure.These three processes were smoothly and coherently transitioned by the hydraulic pressure and control systems.Then,the relevant principles of superimposed liquid supply were described in detail,and the hydraulic working principle of 35 MN fast forging hydraulic press adopting superimposed liquid supply energy-saving technology was introduced.Furthermore,this technology was successfully applied in the actual production.The results show that under the premise of not reducing technical indicators,the installed power using this technology is lower than 1/3 of the current standard unit,and the power consumption of the standard unit without load can meet the normal operation of the unit with significant energy-saving effects and low cost.
