Development of Integration of Electro-hydraulic Power Unit

Shortcomings of conventional electro-hydraulic power unit were analyzed,and some issues existed in conventional electro-hydraulic power unit were partly resolved by the motor-pump combination and hydraulic motor-pump.With the increasing demand for silence,energy saving and human-friend,the electro-hydraulic power unit gradually developed from the discrete structure,the motor-pump combination and the hydraulic motor-pump to the hydraulic power cell.Integrated electro-hydraulic power unit has become one of the essential aspects promoting the development of fluid power technology,and the hydraulic power cell will be widely applied in medium and small power system.
