Abstract
TURBOMÁQUINA DIVIDIDA AXIALMENTE. A presente invenção refere-se a turbomáquinas e, mais especificamente, a turbomáquinas divididas axialmente. As realizações da presente invenção especificamente se referem a disposições de vedação para turbomáquinas divididas axialmente, tal como, por exemplo, bombas centrífugas de múltiplos estágios. Turbomáquina dividida axialmente, que compreende: um invólucro (3) que compreende uma primeira porção de invólucro (5) com uma primeira superfície de contato e uma segunda porção de invólucro (7) com uma segunda superfície de contato; uma disposição de vedação entre a dita primeira porção de invólucro (5) e a dita segunda porção de invólucro (7); um rotor (15) disposto para rotação no dito invólucro (3), sendo que o dito rotor (15) compreende um eixo (17) e pelo menos um propulsor montado no dito eixo (17) ; pelo menos uma passagem de eixo através do invólucro (3), sendo que o eixo (17) se estende através da dita passagem; em que a dita disposição de vedação compreende um membro de vedação linear (35), que se estende entre a primeira superfície de contato e a segunda superfície de contato, e pelo menos uma porção de anel de vedação (37, 39) que envolve a dita pelo menos uma passagem de eixo; em que a dita pelo menos uma porção de anel de vedação (37, 39) e o dito membro de vedação linear (35) formam um corpo de vedação contínua.
