Abstract
Aim To study the mechanical efficiency and volumetric efficiency of inte-grated axial piston type pump-motor system. Methods The study was based on the kinetic and fluid dynamic similitude of hydraulic pump and motor. Results The regressive models of mechanical efficiency and volumetric efficiency of integrated pump-motor system were built and verified by experiments. Conclusion The regressive models can be used to determine the mechanical efficiency and volumetric efficiency of the same type of integrated pump-motor system under any working condition.
