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.
