Abstract

Groupe compresseur centrifuge radial. Les roues à aubes d'un compresseur à plusieurs étages sont entraînées indépendamment les unes des autres à vitesse constante ou variable. L'entraînement des étages du compresseur s'effectue à l'aide d'un moteur à régime réglable ou non réglable, à la vitesse optimale correspondant l'étage intéressé. Un tel compresseur est facile à régler, assure de façon favorable l'arrivée et la sortie du fluide de travail par rapport au refroidisseur ainsi que le passage à la roue à aubes suivante, et dont la sûreté de fonctionnement est améliorée.Radial centrifugal compressor unit. The paddle wheels of a multistage compressor are driven independently of each other at constant or variable speed. The compressor stages are driven by means of a motor with adjustable or non-adjustable speed, at the optimum speed corresponding to the stage concerned. Such a compressor is easy to adjust, provides favorable arrival and exit of the working fluid with respect to the cooler as well as the passage to the next paddle wheel, and the operating reliability of which is improved.
