Description
Technical field
The utility model relates to water turbine slip joint technical field, particularly relates to a kind of runner envelope with seal arrangement that can reduce slip joint stress, optimize leakage-proof effect, improve the operating life of water turbine set and then raising electricity generation efficiency.
Background technique
In prior art, runner envelope and base close contact, should have 2mm gap with pressure ring.When unit normally runs, the alternating stress acting on runner envelope reaches foundation ring through base, and rubber bar is under the extruding of pressure ring, plays sealing effect, thus reaches sealing purpose.
But in real work, owing to there is machining error or distortion, as pressure ring circularity; Installation question, as base and runner envelope decentraction, may occur that runner and base have runner and the gapless situation of pressure ring compared with wide arc gap.When unit normally runs, the alternating stress acting on runner envelope reaches bolt, and this bolt is cut, and through after a while, this bolt fatigue damage finally fractures.When bolt fracture number reach some time, when local pressure ring extruding rubber bar lost efficacy, slip joint water leakage phenomenon will be caused.
Therefore, a kind of runner envelope with seal arrangement that can reduce slip joint stress, optimize leakage-proof effect, improve the operating life of water turbine set and then raising electricity generation efficiency is needed badly.
Model utility content
The purpose of this utility model is to provide a kind of runner envelope with seal arrangement that can reduce slip joint stress, optimize leakage-proof effect, improve the operating life of water turbine set and then raising electricity generation efficiency.
