Title
(EN) WATER-POWER PLANT COMPRISING A BEARING
(FR) CENTRALE HYDROÉLECTRIQUE COMPRENANT UN COUSSINET
Abstract
(EN)
A water-power plant comprising a hydroelectric machine, whereas the hydroelectric machine comprises an oil bearing, whereas the bearing comprises a rotating pari, an oil basin containing oil, a housing structure, at least two compartments, an oil extraction fan, and at least two radial clearances between the rotating pari and the housing structure, whereas a first compartment is confined by the rotating pari, the surface of the oil, the oil basin, the housing structure and one of the radial clearances, whereas the second compartment is confined by the rotating pari, the housing structure and two radial clearances, and whereas the oil extraction fan is connected to the housing structure at a portion of the housing structure confining the second compartment in Order to extract gas out of the second compartment, and whereas the radial width of the radial clearances is at least 1 mm.
(FR)
L'invention concerne une centrale hydroélectrique qui comprend une machine hydroélectrique comportant un coussinet à huile. Le coussinet à huile comprend un élément rotatif, un réservoir d'huile contenant de l'huile, une structure de logement, au moins deux compartiments, un ventilateur d'extraction d'huile, et au moins deux jeux radiaux entre la partie rotative et la structure de logement. Le premier compartiment est confiné par la partie rotative, la surface de l'huile, le bassin d'huile, la structure de logement et l'un des jeux radiaux, tandis que le second compartiment est confiné par la partie rotative, la structure de logement et deux jeux radiaux. Le ventilateur d'extraction d'huile est relié à la structure de logement au niveau d'une partie de celle-ci confinant le second compartiment afin d'extraire le gaz hors du second compartiment. La largeur radiale des jeux radiaux est d'au moins 1 mm.
