HYDRAULIC MACHINE, ENERGY CONVERSION PLANT COMPRISING SUCH A MACHINE AND METHOD OF ADJUSTING SUCH A MACHINE

摘要

This hydraulic machine comprises an impeller (2) able to rotate with respect to a fixed structure (9) and about a fixed axis, this impeller being intended to have passing through it a forced flow of water. At least one device (100) for limiting water leaks is positioned between the impeller (2) and the fixed structure (9), this device defining an operating clearance (J) between the impeller and the fixed structure. This leak limiting device (100) comprises at least one member (103) that can be deformed and/or moved, while the impeller (2) is rotating, in a radial direction (F1) with respect to the axis of rotation of the impeller.
