Abstract

sistema de regulação combin ada da pressão de fluidos de barreira e lubrificação, e unidade para um módulo submarino de motor e bomba. a presente invenção divulga um sistema de regulação da pressão de fluidos de barreira e lubrificação, para um módulo submarino de motor e bomba, compreendendo um circuito de lubrificação de fluido, em comunicação de fluxo com um suprimento de fluido hidráulico, através de um primeiro regulador redutor de pressão (15); e um circuito de fluido de barreira, em comunicação de fluxo com o suprimento de fluido hidráulico, através de um segundo regulador redutor de pressão (14). o primeiro regulador redutor de pressão (15)é configurado para reduzir a pressão do fluido de suprimento em resposta à pressão média bombeada no lado de sucção (4), ou no lado de descarga (5) da bomba, e o segundo regulador redutor de pressão (14) é configurado para reduzir a pressão do fluido de suprimento em resposta à pressão de saída do primeiro regulador redutor de pressão (15). além disso, é igualmente divulgada e disposta uma unidade de regulação de pressão, para alojar os componentes do sistema de regulação dos fluidos de barreira e lubrificação em um vaso pressurizado.combined control system of barrier fluid pressure and lubrication, and unit for an underwater engine and pump module. The present invention discloses a barrier and lubrication fluid pressure regulating system for a subsea motor and pump module comprising a fluid lubrication circuit in flow communication with a hydraulic fluid supply via a first regulator. pressure reducer (15); and a barrier fluid circuit in flow communication with the hydraulic fluid supply via a second pressure reducing regulator (14). the first pressure reducing regulator (15) is configured to reduce the supply fluid pressure in response to the mean pressure pumped at the suction side (4) or discharge side (5) of the pump, and the second pressure reducing regulator Pressure (14) is configured to reduce the supply fluid pressure in response to the outlet pressure of the first pressure reducing regulator (15). In addition, a pressure regulating unit is also disclosed and arranged to house the components of the barrier fluid regulating and lubricating system in a pressurized vessel.
