MONITORING OF A HIGH-PRESSURE PUMP IN A TURBOMACHINE FUEL SUPPLY CIRCUIT

摘要

Device and method for monitoring a high-pressure pump (14) in a turbomachine fuel supply circuit by detecting the opening of a pressurizing and shut-off valve (24) mounted on the outlet side of a fuel flow regulating valve (18), by measuring the rotational speed of the turbomachine corresponding to the opening of the pressurizing and cut-off valve (24) and by monitoring the change in the value of this rotational speed in order to propose replacement of the high-pressure pump (14) when the measured value of the rotational speed reaches a predetermined threshold.
