Beschreibung
Zusammenfassung:	The invention relate to the field of testing inner curve hydraulic motor, in particular to a device for testing the motion and output torque pulsation of a plunger assembly of an inner curve motor, mainly including a pressure oil source, an oil passage, a servo valve control system, a test valve block and a control display terminal, where the pressure oil source, the oil passage and the servo valve control system are all arranged on a mounting base, the pressure oil source is connected with the servo valve control system through an oil passage to provide high-pressure oil for the servo valve control system, the hydraulic oil discharged by the servo valve control system flows into the test valve block for testing, and the test result is fed back to the control display terminal, and the servo valve control system is connected with and controlled by the control display terminal through an external interface. The invention solves the problems that the existing test depends on the whole machine test bench, the control is complicated, the use and maintenance cost are high, and the test accuracy is insufficient.
