摘要：
A testing system scheme with power recycle for hydraulic pumps' durability is present, which is based on a hydraulic motor with hydraulicly overridden pressure compensation. The hydraulic motor can adaptively adjust its displacement to meet the demand of displacement match of the power feedback in the system. The system pressure can be set by adjusting the starting control pressure of the motor. The rotating speed of the pump is guaranteed by the control of the driven electrical motor. A hydraulic bridge unit is used to guide the flow from the outport of the pump to the fixed inlet port of the hydraulic motor and thus causes the motor to rotate in a certain direction to drive the pump in order to recycle the power.
