MAGNETIC BEARING SYSTEM FOR HEAVY LOADED COMPRESSOR

A fluid compression system is disclosed having at least a compressor and a motor (or alternate driver) arranged within a hermetically-sealed housing. The motor rotates a shaft upon which the compressor is disposed, and the shaft is supported within the housing by first and second radial bearings arr...

Beschreibung
Zusammenfassung:	A fluid compression system is disclosed having at least a compressor and a motor (or alternate driver) arranged within a hermetically-sealed housing. The motor rotates a shaft upon which the compressor is disposed, and the shaft is supported within the housing by first and second radial bearings arranged at first and second ends of the shaft, respectively. An intermediate radial bearing is also arranged on the rotatable shaft between the first and second radial bearings. The radial bearings can be active magnetic bearings and controlled by two sets of channels in a bearing control system in order to levitate and control the position of the shaft. L'invention concerne un système de compression de fluide comprenant au moins un compresseur et un moteur (ou un autre entraînement) placés à l'intérieur d'une enveloppe fermée hermétiquement. Le moteur tourne un arbre sur lequel le compresseur est monté, et l'arbre est supporté dans le logement par un premier et un deuxième palier radial situés respectivement à la première et la deuxième extrémité de l'arbre. Un palier radial intermédiaire est aussi monté sur l'arbre rotatif entre le premier et le deuxième palier radial. Les paliers radiaux peuvent être des paliers radiaux magnétiques actifs et être commandés par deux jeux de canaux dans un système de commande de palier afin de provoquer la lévitation et de maîtriser la position de l'arbre.
