Hydraulic power units are relatively easy to operate compared to mechanical power units

Hydraulic is a term used in the mechanical and electromechanical industries. Hydraulic pressure can be transmitted through power transmission, known as hydraulic transmission. Hydraulic pressure can also be used as a control method, known as hydraulic control. Hydraulic transmission uses liquid as the working medium and utilizes the pressure energy of the liquid to transmit power. Hydraulic control uses pressurized fluid as the control signal transmission method
 
Compared with mechanical transmission and electrical transmission, hydraulic transmission has the following advantages:
1. Various components of hydraulic transmission can be conveniently and flexibly arranged according to needs.
2. Lightweight, small in size, low in motion inertia, and fast in response speed.
3. Easy to operate and control, capable of achieving a wide range of stepless speed regulation (speed regulation range up to 2000:1).
4. It can automatically implement overload protection.
5. Mineral oil is generally used as the working medium, and the relative motion surface can self lubricate with a long service life.
6. It is easy to achieve linear motion.
7. It is easy to achieve automation of the machine. When using electro-hydraulic joint control, not only can a higher degree of automatic control process be achieved, but also remote control can be realized.
