Abstract

Patente de Invenção: "ROTOR PARA UMA MáQUINA DE FLUXO, ESPECIALMENTE PARA UMA TURBINA HIDRáULICA". A invenção se refere a um rotor para uma turbina Francis; com uma série de pás, que formam cada vez em pares um canal de fluxo entre si; com um fundo de rotor; com uma coroa de rotor. A invenção é caracterizada pelo fato de que as pás são subdivididas ao longo de uma ou mais juntas de separação em pelo menos duas pás parciais; fundo de rotor e coroa de rotor são subdivididos também, de acordo com as pás parciais, em anéis, de forma que surjam rotores parciais; os rotores parciais individuais podem ser deslocados nas suas posições relativas entre si.Invention Patent: "ROTOR FOR A FLOW MACHINE, ESPECIALLY FOR A HYDRAULIC TURBINE". The invention relates to a rotor for a Francis turbine; with a series of blades, which each time form a flow channel in pairs; with a rotor bottom; with a rotor crown. The invention is characterized by the fact that the blades are subdivided along one or more separation joints into at least two partial blades; rotor bottom and rotor crown are also subdivided, according to the partial blades, into rings, so that partial rotors appear; the individual partial rotors can be moved in their relative positions with each other.
