AMEsim-Based Parameter Design for Ultra-long Hydraulic Oil Pipeline Connecting to Emergency Discharge Mechanism of Deep-Sea Polymetallic Nodules Lifting System
Aiming at potential emergency discharge required during at-sea testing of deep-sea polymetallic nodules lifting system consisting of pipeline and lifting pump,a theoretical calculation was conducted for the hydraulic system of emergency discharge mechanism for at-sea testing,and also a simulation analysis was conducted with AMEsim.It is found that the reliability coefficient of AMEsim for the system is 0.86.An AMEsim-based hydraulic system model was established for the actuator in an at-sea test at 500 m depth.The simulation results show that the oil pipeline in the hydraulic system is 16 mm in diameter,with the set pressure not less than 10.47 MPa,and the action time of actuator is 6 s.This research results can provide a reference for the design of emergency discharge mechanism.
