Abstract

''BOMBA CENTRìFUGA'' Uma bomba centrífuga para bombear uma suspensão de pasta, onde a bomba compreende um corpo (10) com uma entrada e uma saída para a suspensão de pasta e montado sobre um eixo rotativo um rotor com pás de bomba (15), que se estendem de um cubo (16) para o exterior ao longo de um disco de roda (17), onde aberturas (19) para a descarga de gás são formadas no disco de roda (17). O cubo (16) por trás do disco de roda (17) é provido de pás de bomba de vácuo (50), que são circundadas por um alojamento de bomba de vácuo divisível (51) compreendendo uma parede cilíndrica externa (52), que é excêntrica em relação às pás da bomba de vácuo (50), uma parede dianteira (54) com uma abertura de aspiração (55) para o gás e uma parede traseira (53) com uma abertura de exaustão (56) para o gás. A parede traseira (53) é axialmente móvel para ajuste do vácuo por intermédio de uma folga (65) entre as bordas laterias das pás da bomba de vácuo (50) e a parede traseira (53). Uma passagem de gás (59) é prevista entre o disco de roda (127) e a parede dianteira (54) para comunicação entre as aberturas (19) no disco de roda (17) e a abertura de aspiração de gás (55). A abertura de exaustão de gás (56) está conectada com uma saída de gás (58).
