Secondary regulation hydrostatic transmission technology by regulating the hydraulic components carried out to achieve the hydraulic energy and mechanical energy is converted to each other. In general, the mixer hydraulic repair phone, its implementation is based on pressure-based coupled systems, in a device (pump) and secondary components (motor) using fixed-pressure coupling mode, the mixer hydraulic maintenance, rely on real-time adjustment of the motor displacement to balance the load torque. Currently, Hanzhong hydraulic maintenance, the starting point for secondary regulation hydrostatic transmission technology research is to drive the process of recovery and re-use of energy of energy, from a macro point of view of rational allocation of hydrostatic transmission and improve the overall structure of the static Transmission control characteristics of liquid. "Flexible valve" structure not only improves operational sealing performance, but also improve the operating pressure is maintained tightness. For the design of conventional flat disc and roller hydraulic maintenance plant, when operating at elevated pressure valve set pressure (ie, set pressure 95%) of the valve will be "pre-discharge." For spring-loaded safety valve, the "pre-discharge" exists is a normal phenomenon, and the "pre-release" exists to some extent, can help spring-loaded safety valve off.
