Abstract

La presente invención se refiere a un sistema múltiple de sello de extremo de ranura en espiral en tándem, para una flecha rotatoria, que se extiende a través de un alojamiento que contiene un fluido de bajo alta presión, el sistema comprende módulos de sello de extremo corriente arriba (primero) y corriente abajo (segundo), espaciados axialmente, colocados en cámaras selladoras respectivas dentro del alojamiento y que comunican mutuamente a través de un pasaje, cada uno de los módulos tiene caras opuestas de sello, que se extienden radialmente, presentadas por un anillo primario, asegurado al alojamiento y un anillo correspondiente rotatorio con la flecha, los anillos tienen substancialmente el mismo diámetro y geometría de espesor, las caras del sello del anillo correspondiente tiene cada una pluralidad de ranura en espiral de bombeo, radialmente al interior, que se extienden parcialmente a través de su cara al interior desde la circuferencia externa hacia su diámetro interno, un elemento que orienta las caras de sello de los módulos respectivos en forma mutua y las caras de sello, de los módulos respectivos en forma mutua y las caras de sello, que se abre cuando la flecha está girando, por lo cual el gas procedente de la cámara corriente arriba, pasan por las ranuras en espiral del módulo de sello corriente arriba, a través del pasaje en la cámara corriente abajo, y las dimensiones de la ranura en espiral de los módulos de sello respectivo difieren para así producir una caída predeterminada en la presión entre las camaras de sello corriente arriba y corriente abajo.
