Abstract

"TURBINA FRANCIS". é fornecida uma turbina Francis com um formato de lâminas aperfeiçoado para reduzir o fluxo secundário em torno das lâminas e aperfeiçoar a eficiência hidráulica. Uma turbina Francis que compreende uma haste rotativa, uma coroa rodando com a haste rotativa, uma pluralidade de lâminas e uma cinta. A cinta é coaxialmente acoplada com a coroa pelas lâminas e a haste rotativa, a coroa, as lâminas, e a cinta como um todo, são acionadas por água e rodam em uma direção de turbina durante a operação da turbina. Em uma borda dianteira de pelo menos uma das lâminas, existe um ponto máximo local entre a coroa e a cinta. A borda dianteira se inclina na direção de turbina a partir do ponto de conexão de cinta, onde a cinta e a borda dianteira são conectadas. E, uma distância circunferencial na direção de rotação entre o ponto de conexão de cinta e a borda dianteira é a maior no ponto máximo local.
