Problems solved by technology
[0002] The traditional hydraulic power source is a three-stage structure composed of an electric motor, a coupling and a hydraulic pump. It has large volume and weight, large size, leakage at the shaft end, and severe vibration and noise.
Due to the limitation of the working principle of the traditional plunger pump itself, a single plunger can only absorb and discharge oil once per rotation, and its displacement is limited

Description
technical field [0001] The invention relates to the technical field of motor pumps, in particular to a two-dimensional plunger motor pump with conjugate rolling elements. Background technique [0002] The traditional hydraulic power source is a three-stage structure composed of an electric motor, a coupling and a hydraulic pump. It has large volume and weight, large size, leakage at the shaft end, and severe vibration and noise. Due to the limitations of the working principle of the traditional plunger pump itself, a single plunger can only absorb and discharge oil once per rotation, and its displacement is limited. Hydraulic technology is widely used in hydraulic systems such as metallurgical machinery, mining machinery, and engineering machinery. It is developing towards high efficiency, miniaturization, and integration. It is also the driving force for the research and development of hydraulic component design parameters and performance indicators. Contents of the inven...
