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.Summary "Centrifugal Compressor" To reduce the leakage of the sealing part of a centrifugal compressor and to improve the damping characteristic in the sealing part, this centrifugal compressor is equipped with: a housing; a rotor that is attached to this housing. rotatably and to which an impeller is attached, and a labyrinth seal that is attached to the housing and disposed opposite the rotor, a gas is compressed as the impeller rotates, the labyrinth seal is provided at least in impeller end stage inlet portion or a balancing piston balancing impeller propulsion.The rotor diameter opposite the labyrinth seal increases or decreases gradually.In addition, the labyrinth seal is formed from multiple grooves in the axial direction, and several cavities are formed in the circumferential direction in each groove.
