Title: PRESSURE EXCHANGE SYSTEM WITH MOTOR SYSTEM AND PRESSURE COMPENSATION SYSTEM
Abstract:
A system includes a hydraulic energy transfer system configured to exchange pressures between a first fluid and a second fluid. The system also includes a motor system configured to power the hydraulic energy transfer system and a shaft coupling the motor system and the hydraulic energy transfer system. Additionally, the system includes a shaft seal disposed about the shaft. Further, the system includes a pressure compensator configured to reduce a pressure differential across the shaft seal.
