System for pump protection with a hydraulic turbocharger

Abstract:

A system includes a hydraulic energy transfer system configured to exchange pressures between a first fluid and a second fluid. The first fluid is at a higher pressure than the second fluid. The system also includes a high pressure pump configured to increase a pressure of the second fluid. Additionally, the system includes a controller programmed to control one or more valves of the system to selectively route the second fluid to the hydraulic energy transfer system or to the high pressure pump based on an operating condition of the system.
