Title
(EN) SYSTEM FOR HYBRID HYDRODYNAMIC-HYDROSTATIC THRUST BEARINGS
(FR) SYSTÈME POUR DES PALIERS DE BUTÉE HYDRODYNAMIQUES-HYDROSTATIQUES HYBRIDES
Abstract
(EN)
A system includes a hydraulic energy transfer system configured to exchange pressures between a first fluid and a second fluid, wherein the first fluid has a pressure higher than the second fluid. The hydraulic transfer system includes a cylindrical rotor configured to rotate circumferentially about a rotational axis and having a first end face and a second end face disposed opposite each other, a first end cover having a first surface that interfaces with the first end face of the cylindrical rotor, and a hybrid hydrodynamic-hydrostatic bearing system configured to resist axial displacement of the cylindrical rotor.
(FR)
La présente invention concerne un système qui comprend un système de transfert d'énergie hydraulique configuré pour échanger des pressions entre un premier fluide et un second fluide, le premier fluide ayant une pression supérieure au second fluide. Le système de transfert hydraulique comprend un rotor cylindrique configuré pour tourner de manière circonférentielle autour d'un axe de rotation et ayant une première face d'extrémité et une seconde face d'extrémité disposées en regard l'une de l'autre, un premier couvercle d'extrémité ayant une première surface qui forme une interface avec la première face d'extrémité du rotor cylindrique, et un système de palier hydrodynamique-hydrostatique hybride configuré pour résister à un déplacement axial du rotor cylindrique.
