| Abstract: | For oil control valves, the testing platform was designed.The platform included a constant pressure oil supply system which pressure was kept by loading weights.In the platform, a program controlled PWM source was used to excite oil control valve to realize a continuously variable supply current from 0.05 A to 1.05 A.The parameters of oil control valve, including current, flow rate and supply oil pressure, were dynamically inspected and recorded.With a data acquisition and a LabVIEW language program, the platform could automatically export current-flow curve, current-pressure curve and any features based on these curves. |
