Abstract

resumo patente de invenção: "bomba de poço com seção de selo tendo trajetória de fluxo de labirinto em um fole metálico". a presente invenção refere-se a um conjunto de bomba submersível de poço que tem uma bomba rotativa, um motor, e uma seção de selo, acoplados entre o motor e a bomba. a seção de selo tem um alojamento cilíndrico, tendo um adaptador superior e adaptador inferior e um eixo se estendendo axialmente através do alojamento. um tubo-guia envolve o eixo e um fole envolve o tubo-guia. uma passagem de fluido de poço comunica o fluido de poço a uma câmara de fluido de poço, entre o fole e o alojamento. uma passagem de tubo-guia se estende axialmente dentro do tubo-guia, entre o interior e o exterior do tubo-guia de uma porção superior para uma porção inferior do tubo-guia, para comunicar o lubrificante no motor com o lubrificante dentro do fole. 20129980v1
