AXIAL FLOW TURBINE WITH OVERSPEED PREVENTING DEVICE |
摘要 |
<p>An axial flow turbine motor is provided which includes a rotor with a peripheral row of drive blades and a peripheral band-shaped wall element radially clamped against the tops of the drive blades, and a housing with at least one pressure medium inlet nozzle and an annular inner surface surrounding the rotor drive blades and the wall element, wherein the wall element is arranged to withstand centrifugal forces and uphold its clamping engagement with the drive blades at rotor speed levels up to a predetermined speed level, but to expand and loosen its clamping engagement with the drive blades at speed levels above the predetermined speed level, thereby moving into contact with the annular surface and interfering with the rotational movement of the rotor so as to prevent the rotor from reaching hazardous high speed levels.</p> |
