Abstract
In order to test the performance of the pilot handle valve, the test system of the pilot handle valve is developed with LabVIEW measurement and control software, motion control card and XYZ three-axis servo motor. The oil contamination in the valve body is detected when testing the pilot handle valve. In view of the phenomenon that the flow is small and it is difficult to measure accurately when testing the pilot handle valve, the industrial camera is used for image processing and analysis of the leakage. Finally, the reliability of the test system is verified by theoretical analysis and experiment, which meets the requirements of the test-bed company and is accepted successfully.
