Design of Testing System with Power Recycle for Hydraulic Pumps' Durability

A testing system with power recycle for hydraulic pumps durability was designed,which was based on a hydraulic motor with hydraulicly overridden pressure compensation.The displacement of the hydraulic motor can be adaptively adjusted to meet the displacement match condition for the power feedback in the system.And the system pressure can be set by adjusting the starting control pressure of the motor.
