A system includes a pressure exchanger (PX) including a housing and configured to exchange pressure between a first fluid and a second fluid. The system further includes a bearing valve fluidly coupled to the housing of the PX and configured to provide the first fluid to the housing. The system further includes a controller to cause a first adjustment of a first flowrate of the first fluid into the PX based on a target flowrate of first fluid into the PX and the first flowrate. The controller is further to cause a second adjustment of a second flowrate of the second fluid into the PX based on the first flowrate and the second flowrate.

Control of a pressure exchanger system

A system includes a pressure exchanger (PX) configured to receive a first fluid via a first inlet and a second fluid via a second inlet. The PX is to exchange pressure between the first fluid and the second fluid and provide the first fluid at a first outlet and the second fluid at a second outlet. The system further includes a first sensor to provide first sensor data associated with the first fluid prior to the first fluid entering the first inlet and a second sensor to provide second sensor data associated with the second fluid prior to the second fluid entering the second inlet. The system further includes a controller to receive user input and cause a first adjustment of the flowrate of the first fluid into the first inlet and cause a second adjustment of the flowrate of the second fluid into the second inlet.

A system includes an isobaric pressure exchanger (IPX) configured to exchange pressure between a first fluid and a second fluid. The IPX includes a rotor configured to rotate about a longitudinal axis of the rotor. The rotor forms rotor ports arranged substantially symmetrically around the longitudinal axis at a distal end of the rotor. The IPX further includes an end cover configured to be disposed at the first distal end of the rotor. The end cover forms end cover ports. The rotor ports are arranged for hydraulic communication with the end cover ports. The IPX further includes an insert disposed between two of the rotor ports or between two of the end cover ports.
