Title (EN) A CONTROL SYSTEM AND METHOD FOR PROTECTION AGAINST BREAKAGE OF LUBRICANT FILM IN COMPRESSOR BEARINGS.
(FR) SYSTEME ET PROCEDE DE COMMANDE SERVANT A PROTEGER DES PALIERS DE COMPRESSEUR CONTRE LA RUPTURE DU FILM LUBRIFIANT
Abstract: front page image
(EN)The present invention relates to a control system for protection against breakage of the lubricating-oil film in the bearings of hermetic compressors, as well as to a control method that has the objective of guaranteeing that a variable-capacity compressor should be maintained above a minimum rotation in order to prevent the oil film close to the respective bearing from breaking. One of the forms of achieving the objectives of the present invention is by means of a control system for protection against break of the lubricating-oil film in bearings of hermetic compressors, a microprocessor (10) actuating a set of switches (SW2M) selectively, so as to generate a rotation at the motor-compressor assembly (20, 21 ) , the compressor (21 ) having a minimum rotation (RPMmin) of the compressor (21) so that the oil film will not be broken.
(FR)La présente invention concerne un système de commande servant à protéger des paliers de compresseurs hermétiques contre la rupture du film d'huile de graissage dans, ainsi qu'un procédé de commande dont le but est de garantir qu'un compresseur à capacité variable soit maintenu au-dessus d'un seuil de rotation minimum afin de prévenir la rupture du film d'huile se trouvant à proximité du palier correspondant. Pour ce faire, la présente invention fait appel à un système de commande assurant la protection contre la rupture du film d'huile de graissage dans des paliers de compresseurs hermétiques et à un microprocesseur (10) actionnant sélectivement un ensemble de commutateurs (SW2M) de façon qu'une rotation soit générée au niveau de l'ensemble moteur-compresseur (20, 21), lequel compresseur (21) présente une rotation minimum (tr/min minimum) de façon que le film d'huile ne se rompe pas.
