Abstract

respiro de gás para uma seção de vedação de um conjunto de bomba elétrica submersível. a presente invenção se refere a uma seção de vedação (19) de um conjunto de bomba de poço submersível (11) que possui uma bolsa expansível e contrátil (37) circundada por uma câmara de equalização de pressão (41). uma trajetória de comunicação de lubrificante de motor comunica o lubrificante de motor (35) ao interior da bolsa. uma porta de fluido de poço (53) admite o fluido de poço na câmara de equalização de pressão. uma passagem de respiro de gás (65) liga a câmara de equalização de pressão ao exterior. pelo menos uma membrana (67) na passagem de respiro de gás permite que o gás contido no fluido do poço na câmara de equalização de pressão seja ventilado. a membrana impede que o líquido flua através da passagem de respiro de gás para dentro e para fora da câmara de equalização de pressão.
