Hydraulic machine and method for preventing the wear of such a machine |
摘要 |
The machine has a wheel supplied from a casing in which a forced conduit opens. A fixed guide vane series (6) and guiding vane series (7) guide a main flow (E1) that crosses the wheel, where the series (7) has lateral surfaces (71), which are wet by the flow. A circular orifices series (74) at a level of the surfaces (71) constitutes a secondary water flow (E2) with abrasive particle content different from abrasive particle content of the flow (E1). An independent claim is also included for a method for preventing wear out of a hydraulic machine. |
