系统所需要的工作压力（bar）是多少？需要多大的流量？（对于手动泵，每按一次油量：cm3对于动力泵油量L/min）需要单速泵还是双速泵？（双速泵在低压时，流量大，活塞可迅速推进，然后在负载作用下，切换到高压小流量状态）1）人工（手动）：携带方便，适用于没有电和压缩空气的场合2）电动/液压泵：电压是多少？是否需要电池驱动的液压扳手泵？是否需要考虑携带方便？是否为间歇使用，或者需要高频率地使用，需要在带有载荷的情形下起动吗？工作是否会异致泵过热？高频率的使用需要大容量的油箱用以冷却。

齿轮箱在电机中的应用很广泛，在风力发电机组当中就经常用到，而且是一个重要的机械部件直交齿轮箱
，其主要功用是将风轮在风力作用下所产生的动力传递给发电机并使其得到相应的转速。通常风轮的转速很低，远达不到发电机发电所要求的转速，必须通过齿轮箱齿轮副的增速作用来实现，故也将齿轮箱称之为增速箱。
其次齿轮箱还有如下的作用：
1、加速减速,就是常说的变速齿轮箱。
2、改变传动方向，例如我们用两个扇形齿轮可以将力垂直传递到另一个转动轴。
3、改变转动力矩。同等功率条件下，速度转的越快的齿轮,轴所受的力矩越小，反之越大。
4、离合功能：我们可以通过分开两个原本啮合的齿轮,达到把发动机与负载分开的目的。比如刹车离合器等。
5、分配动力。例如我们可以用一台发动机，通过齿轮箱主轴带动多个从轴，从而实现一台发动机带动多个负载的功能。

钢结构螺栓是一种强度高的螺栓。钢结构螺栓也称为高强度螺栓或高强度螺栓接头。它是自2世纪5年代以来发展起来的一种新形式的连接。使用钢结构螺栓连接对很方便?良好的力量性能?并且它是可拆卸的?这是一种非常有前景的连接方法,因为它耐疲劳并且在动态负载下不会松动。钢结构螺栓是高强度螺栓和标准部件。紧固性能好,用于钢结构和工程,以达到紧固效果。在一般钢结构中,所需钢结构螺栓均在8.8以上,有1.9和12.9,均为高强度钢结构螺栓。
