液压的优点
Advantages of Hydraulic Pressure
与机械传动、电气传动相比，液压传动具有以下优点：
Compared with mechanical transmission and electrical transmission, hydraulic transmission has the following advantages:
1、液压传动的各种元件，因根据需要方便、快捷地来布置
1. Various components of hydraulic transmission are arranged conveniently and quickly according to need.
2、重量轻、体积小、运动惯性小、反应速度快。
2. Light weight, small volume, small motion inertia and fast reaction speed.
3、操纵控制方便，可大范围的进行无级调速（调速范围达2000：1）
3. Easy to operate and control, stepless speed regulation can be carried out in a wide range (speed regulation range up to 2000:1)
4、过载时会自动实现过载保护
4. Automatic overload protection when overload occurs
5、一般用矿物油作为工作介质，会对运动面进行自行润滑，且寿命长
5. Mineral oil is generally used as working medium to lubricate the moving surface by itself and has a long service life.
6、容易实现直线运动
6. Easy to realize linear motion
7、容易实现机器的自动化，一旦使用电液联合控制后，不仅可实现更高程度的自动控制过程，而且可以实现遥控。
7. It is easy to realize the automation of the machine. Once combined electro-hydraulic control is used, not only a higher degree of automatic control process can be realized, but also remote control can be realized.
