Compared with mechanical transmission and electric drive, hydraulic transmission has the following advantages:
1, various components of hydraulic transmission can be arranged conveniently and flexibly according to needs.
2, light weight, small volume, small inertia and fast reaction speed.
3, convenient operation and control, can achieve a wide range of stepless speed regulation (speed range of 2000:1).
4. Overload protection can be realized automatically.
5. Mineral oil is usually used as the working medium, and the relative movement surface can be lubricated by itself, and the service life is long.
6, it is easy to achieve linear motion.
7. It is easy to automate the machine. When the electro-hydraulic combined control is adopted, it can not only achieve a higher degree of automatic control process, but also can realize the remote control.
