Abstract
1 / 1 resumo âmãtodo e aparelho para impedir que a capacidade do mancal de empuxo de um sistema de compressão seja excedida durante um evento de surtoâ a presente invenã§ã£o fornece um mã©todo e aparelho para impedir que a capacidade do mancal de empuxo de um sistema de compressã£o seja excedida durante um evento de surto no qual um mancal de empuxo ã© solicitado com uma forã§a de solicitaã§ã£o para aumentar a margem de sobrecarga do mancal de empuxo entre a capacidade de o mancal de empuxo absorver forã§as axiais e a mã¡xima forã§a produzida durante o evento de surto. esta forã§a de solicitaã§ã£o pode ser produzida dimensionando apropriadamente a vedaã§ã£o de alta pressã£o no lado do impulsor oposto ã entrada de um compressor do sistema de compressã£o de forma que a forã§a do disco traseiro produzida na regiã£o de alta pressã£o da vedaã§ã£o de alta pressã£o e a regiã£o de baixa pressã£o localizada para dentro da regiã£o de alta pressã£o cria o valor e direã§ã£o da forã§a de solicitaã§ã£o desejados.
