—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.
