Dispositivo e processo de monitoramento de uma bomba de alta pressão em um curcuito de alimentação com combustível de uma turbomáquina e turbomáquina, tal como um turborreator ou um turbopropulsor de avião

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.
