银通液压机从事多年的液压机系统规划和元器件的出售现在有一些空闲时间双动拉伸液压机，特收拾一些这些年的从业阅历供初入液压这一行的新手参阅单柱液压机。因内容比较多，我将分次书写。在此也请液压职业的高手们和我一同把你们的名贵阅历也写出来传授给那些初学者。

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。液压泵，溢流阀，換向阀。液压泵供给动力源，溢流阀供给液压机系统安全保正，又称安全阀拉伸液压机。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（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 左右的变量叶片泵框架式液压机，这种泵自身带有溢流设备，在做液压站时你可以省去溢流
