Abstract

The invention discloses a hydraulic system for a torque experiment workbench and a control method thereof. The hydraulic system includes a fuel tank and two hydraulic oil circuits for controlling the movement of the hydraulic cylinder; the two hydraulic circuits for controlling the movement of the hydraulic cylinder are connected to the fuel tank. Among them, each hydraulic oil circuit includes oil suction filter, oil pump motor, variable displacement plunger pump, check valve, high pressure filter, pressure switch, pressure gauge, pressure sensor, accumulator, proportional relief valve, proportional converter An integrated valve group composed of a directional valve, a hydraulic control check valve, an oil circuit valve block, a safety protection valve group, and a hydraulic cylinder; the oil suction filter is placed in the oil tank, and the oil suction filter, variable displacement plunger pump, check valve, high pressure The filter, integrated valve group, safety protection valve group and hydraulic cylinder are connected in series in sequence. The hydraulic system applies the force of the pulling (thrusting) hydraulic cylinder to both ends of a mechanical slewing arm to form the torque required for the experiment and meet the needs of the experiment.

Description

technical field [0001] The invention relates to a hydraulic system for a torque experiment workbench and a control method thereof. Background technique [0002] With the full development and utilization of hydraulic components and functional modules, hydraulic systems have been widely used in the field of industrial production.
