【摘要】 在已有液压回路的基础上,提出一种新的、用于实现动力滑台运动的二工进调速阀的二工进速度换接回路,给出其组成图和工作原理。采用FX2N-32MR型PLC设计了其控制系统,得出新回路及其控制系统。同时,以YT4543型液压系统为例,介绍了新回路的应用。更多还原

【Abstract】 On the basis of old hydraulic circuit,brings forward a new valve named speed contorl valve of two work speeds in changes of two work speeds in the hydraulic circuit to realize the movement of power sliding feed table,offers the fig of its makeup and principle of work,designs its control system by PLC(FX2N—32MR),gets characteristic of the new hydraulic circuit and control system.By these,presents the PLC’s broad prospect of application in the field of industrial control.Meanwhile,introduces application of the new circuit in typical hydraulic system of model YT4543.更多还原
