Abstract

disposição de vedação para a vedação de um eixo de bomba em uma bomba de pistão rotativo (10) configurada para transporte de fluido bombeado, compreendendo um dispositivo de bombeamento de fluido de vedação (20) com uma entrada de bomba (21) e uma saída de bomba (22), uma câmara de vedação (40) ligada à saída de bomba (22), a qual está disposta adjacente à câmara de bomba da bomba de pistão rotativo (10) e está vedada em relação à câmara de bombeamento por meio de uma primeira vedação de eixo que envolve o eixo de bomba, sendo que a câmara de vedação (40) é solicitada com pressão de fluido resultante da diferença de pressão de fluido gerada pelo dispositivo de bombeamento de fluido de vedação (20) e, por meio de interação dessa pressão de fluido com a primeira vedação de eixo, veda a câmara de bombeamento contra a saída de fluido bombeado da câmara de bombeamento ao longo do eixo de bomba.
