Abstract

"PROJETOS APERFEIçOADOS DE VEDADOR COM ESCOVA PARA TURBINAS E APARELHO ROTATIVO SIMILAR". Uma turbina com fluxo axial é fornecida com gaxeta retrátil e vedadores com escova entre os estágios. A gaxeta retrátil é fornecida com segmentos de gaxeta separados que formam um anel quando fechados durante a operação normal e se expandem para um vão livre maior durante a partida e paralisação. Um segmento do vedador com escova é fornecido em cada segmento da gaxeta, tal que quando os segmentos são fechados durante a operação normal, o vedador com escova da mesma maneira forma um anel. As extremidades dos segmentos da gaxeta são cortadas ao longo dos raios que se estendem da árvore central, e as extremidades dos segmentos do vedador com escova são chanfradas de modo a não ficarem paralelas com as extremidades dos segmentos da gaxeta nos quais elas se situam.
