Pressure common rail secondary adjustment linear driving system

The invention belongs to the technical field of hydraulic control, and particularly relates to a pressure common rail secondary regulation linear driving system which is characterized in that an energy accumulator is mounted, intermediate pressure is added in conventional high-pressure and low-pressure two-stage pressure, and the pressure of a hydraulic system is divided into multiple stages; the problem that throttling loss of a medium and small load actuator is large due to the fact that the pressure of the hydraulic system is only matched with the highest load is solved, part of loss is reduced, meanwhile, secondary adjusting pressure supply is adopted, the hydraulic system is more energy-saving, and system efficiency is greatly improved. 本发明属于液压控制技术领域，具体为一种压力共轨二次调节直线驱动系统，本发明高低压共轨系统，通过安装蓄能器，在常规高低压两级压力中增加一个中间压力，将液压系统压力分为多个级别，解决了由于液压系统压力只与最高负载匹配导致的中小负载执行器节流损失大的问题，从而降低部分损失，同时采用二次调节压力供给使该液压系统更加节能，大幅改善了系统效率。
