Theoretical Study and Experimental Optimization on the Reliability of a Seawater Hydraulic Solenoid Valve

Shan Wu, Xufeng Zhao, Donglin Li, and Xiaohui Li
Abstract—As an important component of the variable ballast system (VBS), an key subsystem of submersible, seawater hydraulic solenoid shut-off valve(SSV) functions as a transport hub which controls the discharge and injecting of variable ballast cabin. Through theoretical analysis, temperature rise was found to be a main cause of the SSV’s failure. In order to improve the reliability of the SSV, two experimental apparatus were built to test the characteristics of the solenoids and the reliability of the SSV. Result shows variable voltage driving is an effective way of reducing the failure, which can sharply restrain the temperature rise of the solenoids. Moreover, an optimal action cycle was found in which the solenoid valve has a longer continuous on-off time between failures (CTBF) and shorter response time.

Index Terms—Seawater hydraulics, variable ballast system, solenoid shut-off valve, failure analysis.
