| Abstract: | Due that the two-port cartridge valves are broadly applied for HPHV hydraulic systems, different control functionalities can be realized by combining several standardized cartridge components. Pertaining to the faults from directional control loops in a specific two-port cartridge valve debugging process of a flushing pump station, the electro-hydraulic control theory is first oriented. By integrating with the on-site testing and measurement, the faults are then analyzed and detected using the fault tree of hydraulic loops. Finally, relevant solutions on faults are speculated. |
