Abstract

The invention discloses a modularized control device for testing a hydraulic pump and a hydraulic motor. The modularized control device mainly comprises a two-stage reversing module (1), an overflow loading and energy recycling type loading switch module (2), an overflow loading module (3) and an oil return flow processing module (4). All the modules can be integrated on the same hydraulic integration valve block and can also be independently arranged according to actual requirements and connected through pipelines. Based on the concept of modularization design and universality design, a low-power overflow loading function and a high-power energy recycling type loading function are integrated, universality of a hydraulic pump testing platform and universality of a hydraulic motor test platform are improved, the specification of the device for testing the hydraulic pump and the hydraulic motor is reduced, the device utilization rate is increased, and high-power test overflowing loss is reduced.

Description
