AI Technical Summary
Existing technologies make it difficult to accurately test the performance of hydraulic valves, especially under complex and harsh working conditions, where the performance degradation of hydraulic valves caused by the presence of contaminants is difficult to detect.
A hydraulic valve testing system, including a hydraulic pump, a data acquisition unit, and a control unit, is used to collect pressure data, flow data, and drive current to generate characteristic curves, analyze the operating status of the hydraulic valve, and determine whether a fault has occurred.
It enables accurate performance testing of hydraulic valves under polluted conditions, improves the reliability of hydraulic valves, and can detect faults and predict performance degradation in a timely manner.
