Description

Technical field [0001] The invention relates to a testing experiment system, in particular to a testing experiment system for the rotational speed and pressure performance of a hydraulic transformer. Background technique [0002] The hydraulic system has been applied to many occasions due to its high power density, but the hydraulic system also has the shortcoming of low efficiency. Under the increasing energy crisis, the energy saving research of the hydraulic system is becoming a hot spot for the majority of scientific researchers. . [0003] The secondary regulation technology based on the constant pressure network realizes the volume control of the actuators without throttling loss, improves the system efficiency, and can recover and reuse the energy of the load. Although the secondary adjustment hydrostatic transmission system has been widely used in many industries, the working principle of the secondary adjustment hydrostatic transmission system determines that its actuator...
