Compared with mechanical transmission and electric drive, hydraulic transmission has the following advantages:
1, hydraulic transmission of various components, according to the need for convenient, flexible to decorate.
2, light weight, small size, small motion inertia, fast reaction speed.
3, convenient control, can achieve a wide range of stepless speed Regulation (speed range up to 2000:1).
4. Overload protection can be realized automatically.
5, the general use of mineral oil as a working medium, the relative motion surface can be self-lubricating, long service life;
6, it is easy to achieve linear motion.
7, it is easy to realize the automation of the machine, when the use of electro-hydraulic joint control, not only to achieve a higher degree of automatic control process, but also to achieve remote control.
