Single-execution element load port independent control hydraulic experiment system

Abstract

The invention discloses a single-execution element load port independent control hydraulic experiment system. The system comprises a hydraulic oil tank (1), a filter (2), a motor (3), a hydraulic pump(4), an overflow valve (22), throttling valves (6,7,13,14), a hydraulic cylinder (9), a control system (19) and a plurality of sensors, wherein the plurality of sensors are connected with the controlsystem (19), various data and information in the experimental system can be fed back to a display (2-3) in the control system (19) in real time and can store in a controller and a power system (2-1).According to the system, the load port independent control experiment can be realized without a pipeline, experimental data can be collected, stored and analyzed in real time, flexible switching of the differential circuit and the throttling speed regulation loop can be realized, the switching efficiency of different loops is improved, the service life of the system is prolonged, the leakage of hydraulic oil is avoided, and the experimental efficiency and effect are improved.

Description

AI Technical Summary

Problems solved by technology

The valves of the hydraulic control system in the prior art are generally coupled to the inlet and outlet, that is, there are only two degrees of freedom; and the oil inlet and the oil return port are mechanically related, and there are only two degrees of freedom, so the inlet and outlet cannot be flexibly adjusted. The oil port and the oil return port are independently controlled; therefore, there are technical defects such as inflexible control of the actuator and poor control performance; at the same time, due to the passive increase of the throttling pressure loss of the oil port, the temperature of the hydraulic oil increases. Reduced efficiency of the hydraulic transmission system, etc.
