Abstract
UNE CENTRALE D'ALIMENTATION EN HUILE SOUS PRESSION POUR PALIERS DE BUTEE DE POMPES CENTRIFUGES COMPORTE UNE POMPE A ENGRENAGES 2 ENTRAINEE EN ROTATION PAR L'ARBRE 1 DE LA POMPE CENTRIFUGE. POUR ELIMINER LA NECESSITE D'UNE ALIMENTATION EN HUILE SEPAREE LORSQUE LA POMPE CENTRIFUGE TOURNE A BAS REGIME, UN ACCUMULATEUR 5 MONTE DANS L'ENSEMBLE DE PALIER A LUBRIFIER OU SUR CET ENSEMBLE, QUI EST RELIE PAR UNE CONDUITE D'AMENEE A LA POMPE A ENGRENAGES ET PAR UNE CONDUITE DE DEPART AU PALIER DE BUTEE 4. APPLICATIONS: GRAISSAGE DES PALIERS DE BUTEE DE POMPES CENTRIFUGES.A PRESSURIZED OIL SUPPLY FOR CENTRIFUGAL PUMP THRUST BEARINGS INCLUDES A GEAR PUMP 2 DRIVEN IN ROTATION BY SHAFT 1 OF THE CENTRIFUGAL PUMP. TO ELIMINATE THE NEED FOR A SEPARATE OIL SUPPLY WHEN THE CENTRIFUGAL PUMP IS RUNNING AT LOW SPEED, AN ACCUMULATOR 5 FITTED IN THE BEARING ASSEMBLY TO BE LUBRICATED OR ON THIS ASSEMBLY, WHICH IS CONNECTED BY A DELIVERY DUCT TO THE PUMP A GEARS AND THROUGH A STARTING DUCT AT THE THRUST BEARING 4. APPLICATIONS: LUBRICATION OF THE THRUST BEARINGS OF CENTRIFUGAL PUMPS.

Le problème posé par une centrale de ce type, qui, lorsque la pompe centrifuge fonctionne, est indépendante d' un apport d'huile extérieur, réside dans la nécessitd de pallier l'absence de circulation d'huile au démarrage et lors d'un départ d'urgence éventuel En effet, dans de telles circonstances de fonctionnement, on ne dispose pas de la pression d'huile nécessaire au graissage du palier de butée, car la pompe à engrenages ne commence à débiter qu'à partir d'une certaine vitesse de rotation de l'arbre The problem posed by a plant of this type, which, when the centrifugal pump is running, is independent of an external oil supply, lies in the need to overcome the absence of oil circulation at startup and during a In such operating circumstances, the oil pressure necessary for lubricating the thrust bearing is not available because the gear pump only starts to run from a certain point in time. speed of rotation of the tree
