摘要

A method of increasing strength and rigidity of stay ring of a large low head turbine by stiffening cylinders consists of reducing the mounting height of top cover (5), height of guide vane trunnion (4), diameter of guide vane stems (4) and size of guide vane servomotor wherein the stiffening cylinders (11,13) are welded on top-deck (8) of stay ring (7) to give the required strength and rigidity to the stay ring (7) without increasing the height of the top cover (5) and guide vane stem/trunnion (4) and stiffening plate (9) are welded between top deck (8) and stiffening cylinders ( 11,13) to give extra strength at the location of stay vanes (2) when ribs (10, 12, 14) are welded between stiffening plate (9), top deck (8) and stiffening cylinders (11,13) to add strength and rigidity to stay ring (7).
