初入行者可先从规划液压站开端。基本的液压站含有以下几个关键元件250吨单柱液压机。液压泵单柱液压机，溢流阀，換向阀。液压泵单柱液压机供给动力源，溢流阀供给液压机系统安全保正，又称安全阀。換向阀用于操控液压履行机构的作业（油缸，油马达）。下一节从怎么选液压泵单柱液压机（油泵）开端讲。选油泵首要二个参数，压力和流量。先说压力。如果你的油缸只需输出1 到2 吨的力，你可选2.5MPa 的齿轮泵。因为这个系列的油泵价格低，功用牢靠。如果你的油缸要输出3 到5 吨的力可选7MPa 左右的变量叶片泵，这种泵自身带有溢流设备，在做液压站时你可以省去溢流

阀框架式液压机，这不仅是省一个溢流阀的问题，在做液压站时还能简化油路。
