Abstract
L'invention concerne des techniques permettant de régler une pompe à déplacement positif à double vis comportant un processeur de signal permettant de recevoir une signalisation contenant des informations concernant des données de performance de pompe réelle pour des conditions nominales réelles capturées au cours d'une fonction de réglage relative au fonctionnement de la pompe à déplacement positif à double vis ; et de déterminer des données de performance de pompe corrigée pour faire fonctionner la pompe à déplacement positif rotatif par compensation des données de performance de pompe utilisées pour faire fonctionner la pompe à déplacement positif à double vis sur la base des données de performance de pompe réelle pour les conditions nominales réelles capturées au cours de la fonction de réglage. Les données de performance de pompe corrigée comprennent des données de performance de pompe publiées présentant une puissance nominale et un facteur de glissement publiés, et les données de performance de pompe réelle contiennent des informations relatives à la puissance réelle, au poids et à la viscosité spécifiques associées au fonctionnement de la pompe à déplacement positif à double vis et reçues en provenance d'un contrôleur de pompe, comprenant un variateur de fréquence.
