Abstract

resumo "compressor centrífugo” para reduzir o vazamento da parte de vedação de um compressor centrífugo e para melhorar a característica de amortecimento na parte de vedação, esse com-pressor centrífugo é equipado com: um invólucro; um rotor que é preso nesse invó-lucro de modo giratório e ao qual é fixado um impulsor; e uma vedação tipo labirinto que é fixada ao invólucro e é disposta oposta ao rotor. um gás é comprimido à me-dida que o impulsor gira. a vedação tipo labirinto é fornecida pelo menos na parte de entrada do estágio final do impulsor ou um pistão de equilíbrio que equilibra a propulsão do rotor. o diâmetro do rotor oposto à vedação tipo labirinto aumenta ou diminui gradualmente. além disso, a vedação tipo labirinto é formada de múltiplos sulcos na direção axial, e são formadas várias cavidades na direção circunferencial em cada sulco.
