Abstract

COMPRESSOR CENTRìFUGO. A presente invenção refere-se a um compressor centrífugo dotado de uma ampla faixa de operação, sendo economicamente eficiente e altamente confiável em termos de uma operação estável. Emprega-se um compressor centrífugo que inclui um tabique 37 para dividir um canal de fluxo na seção difusora 15 e a seção voluta 16 dentro de uma pluralidade de canais na direção de circulação do fluido, para definir um canal de fluxo do lado do eixo A e um canal de fluxo do lado do envoltório B; e uma válvula ajustadora de índice de fluxo 36 para diminuir o índice de fluxo do fluido que flui no canal de fluxo do lado do envoltório B para aumentar o índice de fluxo no canal de fluxo do lado do eixo A quando o índice de fluxo do fluido comprimido pelo impulsor 13 for baixo e não diminuir o índice de fluxo do fluxo que flui no canal de fluxo do lado do envoltório B, a fim de permitir que o fluido flua tanto no canal de fluxo do lado do envoltório B quanto no canal de fluxo do lado do eixo A quando o índice de fluxo do fluido comprimido pelo impulsor 13 for alto.
