Secondary regulation hydrostatic transmission compared with conventional hydrostatic transmission, the advantage is more easy to control, can work in four quadrants, you can not change the recovery in energy, the energy stored in the form of lower energy, the use of hydraulic accumulators acceleration transducers can greatly improve acceleration power, and the system is no pressure peak, Shangluo mixer maintenance, since the first element and the second element is installed separately, providing oil source to a plurality of hydraulic power element by a pumping station, reducing cooling costs manufacturing equipment to reduce costs, high system efficiency. 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. Generally speaking, mixer repair company, its implementation is based on pressure-based coupled system, mixer repair phone, the primary element (pump) and secondary components (motor) using fixed-pressure coupling mode, mixer repair method, relying on real-time adjustment to balance the load torque motor displacement. Currently, 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 its hydrostatic transmission control characteristics.
