Abstract
1360117 Seals SOC RATEAU S June 1972 [3 June 1971] 26186/72 Heading F2B A liquid barrier shaft seal for a turbine comprises a sealing block 4 mounted astride a shaft flange 3 and having hydrodynamic lift generating shoes 12, and surfaces 9 that co-operate with the flange to limit leakage of the barrier liquid. The block 4 consists of two parts 4a, 4b spaced apart by a spacer 6 and prevented from rotating by a peg 35 within a housing 5. The shoes 12 are arranged in series in each of their dovetail grooves, the bottoms of the grooves being stepped to allow the shoes to rock in operation. Barrier oil at a pressure higher than that in the spaces A, B passes from a feed conduit 42a to a return conduit 42b via passages 17a, 45 and 17b, part of the flow being allowed to leak at Q
