The Design of Electric Control System of Proportional Electromagnetic Valve Test Bench

摘要

For high precision detection of hydraulic proportional solenoid valve pressure, sealing properties and steady pressure characteristic performance indexes, independently design a solenoid valve performance testing platform, which has a high level of automation. Its core based on PLC controller and touch screen, it makes power units, hydraulic integrated block, test valve installation disc, and other components as its control object, and adopt the input and output module to make up an open structure supervisory computer control system to realize data preprocessing, sensor linearization and nonlinear compensation, scale transform, the limit alarm function processing engineering, digital controller, meeting the proportional solenoid valve testing requirements. The article describes in details the constitute of test platform of electronic control system, work principle and the realization of the function of each part.
