Abstract

Procédé de suivi du rendement volumétrique d'une pompe haute-pression d'un système de régulation hydraulique d'une turbomachine comportant une pompe volumétrique haute-pression délivrant un débit Q, fonction d'un régime moteur N de la turbomachine défini par un calculateur de commande, en direction d'un vérin d'actionnement des aubes à géométrie variable de la turbomachine et d'une vanne de by-pass disposée dans une canalisation d'alimentation des moteurs de la turbomachine, procédé dans lequel on met en route des moteurs à un bas régime moteur N0, la vanne étant fermée, on commande un déplacement du vérin, on augmente progressivement le régime moteur N jusqu'à ce que le débit Q atteint une valeur prédéterminée Q0 suffisante pour ouvrir la vanne, on stocke dans le calculateur d'une part la position du vérin et d'autre part le régime moteur N correspondant à l'ouverture de la vanne, on répète les étapes précédentes à des instants t1, t2, tn successifs durant la durée de vie des moteurs, et on remplace la pompe volumétrique haute-pression lorsque le régime moteur N excède une valeur prédéterminée Nlimite.
