System and method for driving a pump

摘要

A system for driving a pump includes a gas turbine engine having an output shaft, and a torque converter including an input shaft coupled to the output shaft of the gas turbine engine and an output shaft configured to be coupled to an input shaft of a pump. The system further includes a controller coupled to the torque converter, wherein the controller is configured to receive a signal indicative of a pressure at at least one of a pump inlet and a pump outlet, and control a speed of the output shaft of the torque converter based on the signal indicative of pressure.

1. A system for driving a pump configured to receive fluid at a pump inlet and discharge the fluid at a pump outlet, the system comprising:
a gas turbine engine having an output shaft; a torque converter including an input shaft coupled to the output shaft of the gas turbine engine, and an output shaft configured to be coupled to an input shaft of the pump; and a controller coupled to the torque converter, wherein the controller is configured to:
receive a signal indicative of a pressure at at least one of the pump inlet and the pump outlet,control a speed of the output shaft of the torque converter based on the signal indicative of pressure, andcontrol the speed of the output shaft of the torque converter independent of a speed of the output shaft of the gas turbine engine.
