Abstract

995,654. Hydraulic turbines. DOMINION ENGINEERING WORKS Ltd. June 4, 1962 [June 5, 1961], No. 21555/62. Heading FIT. A vertically mounted Francis turbine includes a stationary structure permanently secured in a foundation, a runner having band and crown elements mounted within the stationary structure, sealing means located between adjacent portions of the band and stationary structure comprising at least one removable sealing element secured to one of the adjacent portions and adapted to be released substantially intact from within the confines of the stationary structure to permit withdrawal of the runner and released sealing means from the stationary structure in the event of a seizure of the sealing means. A band seal element 9 is welded at 10 to the runner 4 of a Francis turbine and a stationary seal element 1 is either welded at 3 to the casing 2 or is integral therewith. The casing 2 is permanently secured in a foundation. In the event of seizure of the seals 1, 9 the welds 3 or 10 can be broken from within the casing 2, and the runner 4 lifted out. A seal 5 is secured in the top cover 6 adjacent the runner crown 7. In a modification, Fig. 1 (not shown) the band seal comprises only the element 1 welded to the casing 2.
