Tubing & casing compared with mechanical transmission, electric drive, hydraulic drive has the following advantages:
1, The various components of the hydraulic drive, can easily and flexibly be arranged as needed.
2, Light weight, small size, low inertia, fast response.
3, Easy operation control, can achieve a wide range of variable speed (speed range up to 2000: 1).
4, Automatic overload protection.
5, Generally use mineral oil as the working medium, the relative movement surface can be self-lubricating, long life;
6, It is easy to achieve linear motion /
7, It is easy to automate the machine, when the electro-hydraulic joint control, not only to achieve a higher degree of process automation, and remote control can be achieved.
