Semi-automatic test bed for oil-tight pressure maintaining of hydraulic system

The utility model provides a semi-automatic test bed for oil-tight pressure maintaining of a hydraulic system, and belongs to the technical field of aviation product detection. The test bed body serves as a bearing mechanism, the hydraulic function start-stop button, the valve switch, the instrument panel and the hydraulic cylinder connecting oil port are arranged on the test bed body, hydraulic components are all connected through rubber hoses and then installed in the test bed body, and semi-automatic operation is achieved through the quantitative electric pump, the electromagnetic reversing valve and the pressure relay. Therefore, impact of a hydraulic system is reduced, and dependence on the proficiency degree of workers is avoided. The hydraulic control system is convenient to operate, visual in display, safe, stable and reliable, hydraulic impact of the system can be reduced, hydraulic components can be well protected, the operation difficulty of operators can be reduced, and labor intensity can be redu
