Abstract: A new secondary regulation hydraulic system is introduced, in which the entrances and exports of variable-displacement motors in traditional secondary regulation system based on fixed-pressure net are serially connected. A fixed displacement pump is applied as the oil supply, so that the flow-rate through each variable-displacement motor equals to the output flow-rate of pump approximately. In this way, a secondary regulation system based on fixed flow-rate net is composed of. Based on this, the structure of high-speed switchmode secondary regulation system based on fixed flow-rate net, which could enhance its low-speed characteristic, is put forward. Corresponding theoretical analysis and simulations show that the virtues in traditional secondary regulation system based on fixed-pressure net such as high efficiency and energy reclama-tion are inherited, and the structure is simplified remarkably. The throttle lost is decreased considerably, and the energy saving efficiency is optimal.
