R901106448力士乐压力继电器 HED8OA-2X/200K14KW
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。

5.控制精度
1）普通电磁阀只有开、关两个位置，在控制精度要求高和参数要求平稳时需选用多位电磁阀；
2）动作时间：指电信号接通或切断至主阀动作完成时间；
3）泄漏量：样本上给出的泄漏量数值为常用经济等级。

齿轮泵是依靠泵缸与啮合齿轮间所形成的工作容积变化和移动来输送液体或使之增压的回转泵。由两个齿轮、泵体与前后盖组成两个封闭空间，当齿轮转动时，齿轮脱开侧的空间的体积从小变大，形成真空，将液体吸入，齿轮啮合侧的空间的体积从大变小，而将液体挤入管路中去。吸入腔与排出腔是靠两个齿轮的啮合线来隔开的。齿轮泵的排出口的压力完全取决于泵出处阻力的大小。

水流通过减压阀虽有很大的水头损失，但由于减少了水的浪费并使系统流量分布合理、改善了系统布局与工况，因此总体上讲仍是节能的。介质为蒸汽的场合，宜选用先导活塞式减压阀或先导波纹管式减压阀。为了操作、调整和维修的方便，减压阀一般应安装在水平管道上。
