Title
(EN) AIR COMPRESSOR SYSTEM AND METHOD OF OPERATION
(FR) SYSTÈME DE COMPRESSEUR D'AIR ET PROCÉDÉ DE FONCTIONNEMENT
Abstract
(EN) Air compressor systems, upgrade kits, computer readable medium, and methods for controlling an air compressor for improved performance. The methods may include receiving a working air requirement; determining an estimated air pressure of the air compressor to deliver the working air requirement; measuring a pressure of the air compressor; comparing the measured pressure with the calculated estimated air pressure; if the measured pressure of the air compressor is greater than the determined estimated air pressure by a predetermined greater amount, then decreasing an output control of the air compressor; and if the measured pressure of the air compressor is less than the calculated estimated air pressure by a predetermined lesser amount then increasing the output control of the air compressor. The air compressor may be controlled based on a measured pressure of delivered working air. An oil control system may shut off oil to parts of the air compressor.
(FR) L'invention porte sur des systèmes de compresseur d'air, sur des ensembles remise à neuf, sur un support lisible par un ordinateur, et sur des procédés pour commander un compresseur d'air pour des performances améliorées. Les procédés peuvent mettre en œuvre la réception d'une exigence d'air de travail ; la détermination d'une pression d'air estimée du compresseur d'air pour fournir l'exigence d'air de travail ; la mesure d'une pression du compresseur d'air ; la comparaison de la pression mesurée avec la pression d'air estimée calculée ; si la pression mesurée du compresseur d'air est supérieure à la pression d'air estimée déterminée d'une quantité supérieure à une quantité prédéterminée, alors, la diminution d'une commande de sortie du compresseur d'air ; et si la pression mesurée du compresseur d'air est inférieure à la pression d'air estimée calculée d'une quantité inférieure à une quantité prédéterminée, alors, l'augmentation de la commande de sortie du compresseur d'air. Le compresseur d'air peut être commandé sur la base d'une pression mesurée d'air de travail distribué. Un système de commande d'huile peut interrompre l'huile vers des parties du compresseur d'air.
