| 摘要 |
A motor and a pump barrier fluids pressure regulation system for a subsea motor and pump module is disclosed. The pressure regulation system comprises-a barrier fluid circuit (10) providing fluid flow communication from a hydraulic fluid supply (8) to a first cavity in the motor and pump module,-a pressure controlled flow control valve (9) controlling the supply of hydraulic fluid to the barrier fluid circuit (10);-a second cavity arranged to receive hydraulic fluid from the hydraulic fluid supply via the first cavity, and-a pilot pressure circuit (11) comprising means for detecting and returning to the pressure controlled flow control valve (9) a differential pressure over a flow restriction (7; 13) connecting the first and second cavities. |
