Abstract

resumo patente de invenção: "método e bomba para bombear fluidos altamente viscosos". a presente invenção refere-se a uma bomba (1) para o bombeamento de fluidos altamentes viscosos, que inclui um invólucro (3), uma entrada (7), uma saída (8) e um impulsor fechado (5) giratoriamente dispostos no invólucro entre a entrada e a saída, e que tem um espaço lateral (6) entre uma mortalha (4) do impulsor e do invólucro (3). além disso, a bomba (1) inclui um elemento de vedação (7a, 7b, 8a, 8b) entre o impulsor (5) e o invólucro (3), cada um em uma lateral de entrada e em uma lateral de saída do impulsor para restringir o fluxo de retorno através do espaço lateral (6) e para permitir que o fluido contido no espaço lateral aqueça, e uma porta de injeção (9), conduzindo dentro do espaço lateral (6) para a injeção de um fluido dentro do espaço lateral para diminuir o atrito entre a mortalha (4) do impulsor e o invólucro (3).
