Abstract

um conjunto de bomba de poço inclui uma bomba centrífuga (19) tendo um alojamento (33) com uma parede lateral interna cilíndrica (35). os difusores superiores e inferiores (39, 41) estão localizados no alojamento. uma vedação metal para metal (65 ou 91, 99) veda uma porção de extremidade superior do difusor inferior à porção de extremidade inferior do difusor superior. a vedação também possui uma superfície externa (81 ou 94) que engata de forma friccional na parede lateral interna do alojamento. a vedação é energizada em resposta a uma força axial exercida entre os difusores superiores e inferiores. uma versão tem um anel de vedação de metal (65) localizado em recessos coincidentes (73, 77) nas paredes externas dos difusores. outra versão inclui um rebordo interno (99) em uma das porções de extremidade dos difusores que se estende dentro e deflete um rebordo externo (91) na outra das porções de extremidade dos difusores.
