A pressure exchanger includes a rotor configured to exchange pressure between a first fluid at a first pressure and a second fluid at a second pressure. The rotor forms ducts that are routed from a first distal end to a second distal end. The rotor forms chamfers on trailing edge rotor duct walls. The pressure exchanger further includes a first end cover that forms a high pressure in (HPIN) port configured to provide the first fluid at the first pressure into the ducts. The first end cover forms a low pressure out (LPOUT) port configured to receive the first fluid from the ducts at a third pressure. The pressure exchanger further includes a second end cover that forms a low pressure in (LPIN) port configured to provide the second fluid at the second pressure into the ducts and forms a high pressure out (HPOUT) port configured to receive the second fluid from the ducts at a fourth pressure.

Reducing cavitation, noise, and vibration in a pressure exchanger

A system includes a pressure exchanger and one or more valves. The pressure exchanger includes a rotor that is configured to exchange pressure between a first fluid and a second fluid. The pressure exchanger further includes a housing disposed around the rotor, one or more flushing inlets coupled to the housing, and one or more flushing outlets coupled to the housing. The one or more first valves are coupled to the one or more flushing outlets. The one or more first valves in an open position are associated with a flushing operation. The one or more first valves in a closed position are associated with a lubrication operation.
