Abstract

bomba de sangue turbo e método para produzir a mesma a presente invenção refere-se a um impulsor (5) que tem uma estrutura na qualo as extremidades internas de algumas de uma pluralidade de palhetas (6) são acopladas a um eixo giratório (7), e as extremidades externas das palhetas individuais são acopladas a uma porção de acoplamento anular (8). a base (27) é formada ao permitir que a parede de fundo de um alojamento (1) se saliente para cima, e tem uma superfície circunferencial cilíndrica externa que corresponde a um espaço na região interna da porção de acoplamento anular. um orifício de montagem de mancal (28) é proporcionado na porção central da superfície superior da base, e projeções de parafuso internas (28a) são formadas na superfície circunferencial interna do orifício de montagem de mancal. um mancal inferior (26) para suportar a extremidade inferior do eixo giratório do impulsor é montado no orifício de montagem de mancal. o mancal inferior tem uma porção de mancal (31) e projeções de parafuso externas (26a) que têm que ser aparafusadas nas projeções de parafuso internas e formadas na superfície cincunferencial externa do mancal inferior. a posição vertical do mancal inferior com relação ao orifício de montagem de mancal pode ser ajustada por meio da conexão de parafuso entre as projeções de parafuso externas e as projeções de parafuso internas. a estrutura para ajustar a posição do mancal inferior pode ser proporcionada por um pequeno número de componentes sem qualquer processamento adicional da base após a moldagem de injeção.
