摘要

Efficient and energy-saving are the development tendencies of the pre-bending machine. The new pre-bending machine is consisted of a constant pump driven by servo motor instead of common motor, variable pump and proportion valve. The advantage of this hydraulic system is energy-saving and it's a closed-loop which controls the hydraulic system. In order to get different flow, it needs to adjust the servo motor speed by the control unit. This hydraulic system not only has a good performance, but also can significantly reduce energy consumption.
