HED8OH-20/50K14AS压力继电器

首先用于安全保护时，将压力继电器设置在夹紧液压缸的一端，液压泵启动后，首先将工件夹紧，此时夹紧液压缸的右腔压力升高，当升高到压力继电器的调定值时，压力继电器动作，发出电信号使2YA通电，于是切削液压缸进刀切削。在加工期间，压力继电器微动开关的常开触点始终闭合。若工件没有夹紧，压力继电器2断开，于是2YA断电，切削液压缸立即停止进刀，从而避免工件未夹紧被切削而出事故。
其实用于控制执行元件的顺序动作时，液压泵启动后，首先2YA通电，液压缸左腔进油，推动活塞方向右移。当碰到限位器(或死挡铁)后，系统压力升高，压力继电器发出电信号，使1YA通电，高压油进入液压缸的左腔，推动活塞右移。这时若3YA也通电，液压缸的活塞快速右移;若3YA断电，则液压缸的活塞慢速右移，其慢速运动速度由节流阀调节。
再次用于液压泵卸荷时，压力继电器不是控制液压泵停止转动，而是控制二位二通电磁阀，将液压泵5输出的压力油流回油箱，使其卸荷。
最后用于液压泵的启闭时，有两个液压泵，高压小流量泵，低压大流量泵。当活塞快速下降时，两泵同时输出压力油。当液压缸活塞杆抵住工件开始加压时，压力继电器在压力油作用下发出动作，触动微动开关，将常闭触点断开，使液压泵停转。在加工过程中减慢液压缸的速度，同时减少动力消耗。
