Advantages and Disadvantages of Hydraulic System of Plate Bending Rolls

Compared with mechanical drive, electric drive, the hydraulic system of plate bending roll has the following advantages.
A. The hydraulic system is convenient to operate and control, able to realize a wide range of variable speed adjustment (speed range is up to 2000:1).
B. The hydraulic system has light weight, small size, small inertia, and fast response.
C. The hydraulic system can realize automatic overload protection.
D. The hydraulic system is very easy to achieve linear motion.
E. The various components and vertical dryer of the hydraulic system can be easy and flexible to arrange as needed.
F. The hydraulic system is very easy to realize machine automation, and after the use of combined electro-hydraulic control, it can not only achieve a higher degree of automatic control process, but also realize remote control.
G.The hydraulic system generally uses mineral oil as working medium, and the relative motion surface can be self-lubricated with long service life.

Compared with hydraulic transmission, the hydraulic system has the following disadvantages.
A. It requires a higher precision, so it is expensive.
B. For the influence of the work performance of its medium leakage and compressibility, it cannot reach the strict transmission ratio.
C. As a result of performance vulnerable to temperature changes, it should not work under the conditions of high or low temperature.
D. The fluid flow resistance and leakage is high, so the efficiency is relatively low. If not handled properly, leakage will not only contaminate sites, but also cause fires and explosions.
