液压泵压力
液压泵工作压力是指泵（或马达）在实际工作时输出（或输入）油液的压力，由外负载决定。
额定压力是指在正常工作条件下，按试验标准规定能连续运转的最高压力。其大小受寿命的限制，若超过额定压力工作，泵（或马达）的使用寿命将会比设计的寿命短。当工作压力大于额定压力时称超载。

工作时，在喷油泵凸轮轴上的凸轮与柱塞弹簧的作用下，迫使柱塞作上、下往复运动，从而完成泵油任务，泵油过程可分为以下三个阶段。
结论：通过上述讨论，得出下列结论
① 柱塞往复运动总行程L是不变的，由凸轮的升程决定。
② 柱塞每循环的供油量大小取决于供油行程，供油行程不受凸轮轴控制是可变的。
③ 供油开始时刻不随供油行程的变化而变化。
④ 转动柱塞可改变供油终了时刻，从而改变供油量。

5、根据持续工作时间长短来选择：常闭、常开、或可持续通电
1）当电磁阀需要长时间开启，并且持续的时间多于关闭的时间应选 用常开型；
2）要是开启的时间短或开和关的时间不多时，则选常闭型；
3）但是有些用于安全保护的工况，如炉、窑火焰监测，则不能选常开的，应选可长期通电型。
6、根据环境要求选择辅助功能：防爆、止回、手动、防水雾、水淋、潜水。

位置定位器实质上是一个将控制信号与位置反馈信号进行比较并放大以控制电动机开停和旋转方向的多功能大功率放大板，它与执行机构的动力部件相连以控制执行机构按系统规定的状态工作。位置定位器主要由比较、逻辑保护、放大驱动及功率放大等电路组成。控制单相电动机的位置定位器功率放大部分主要由光电祸合过零触发固态继电器（无触点电子开关）构成。其主体部分示意如图4所示。需要注意的是“手动一自动”转换开关，该开关的作用是在没有外加信号时，与手动调整电位器P1配合使用，以便观察或调试执行机构。用后一定要将其拨回“自动”位世，以免影响投人系统自动控制。
