Latest Patents

Junwei Dong holds a patent for a system designed for electro-hydraulic control of hydraulic pipeline rupture protection based on differential pressure feedback. This system comprises a hydraulic actuation system and a controller system. The controller system includes a differential pressure feedback loop and a flow rate diagnostic loop. The differential pressure feedback loop is responsible for obtaining a flow rate signal within a hydraulic pipeline and determining a proportional signal. The flow rate diagnostic loop receives this proportional signal and, upon determining that the duration for which the proportional signal remains outside a threshold range reaches a preset safety duration, it cuts off the actuating end of the hydraulic actuation system to achieve pipeline rupture protection. This innovative approach significantly enhances the safety measures in hydraulic systems.
