High-pressure pump monitoring device for e.g. jet engine, of aircraft, has comparing unit for comparing value with predetermined threshold to direct replacement of high-pressure pump in fuel supply circuit when value attains threshold

摘要

The device has an opening detector (28) for detecting the opening of a disconnection and pressurization valve (24) of a fuel supply circuit (26) of injectors (20) of a turbomachine. A processing unit (32) registers a value measured from rotational speed of the turbomachine at the opening of the valve. A comparing unit compares the value with a predetermined threshold to direct the replacement of a high-pressure pump (14) in the fuel supply circuit when the value attains the predetermined threshold. An independent claim is also included for a method for monitoring a high-pressure pump in a fuel supply circuit of a turbomachine.
