Abstract

bomba centrífuga radialmente dividida com dois fluxos paralelos de meio bombeado. a invenção se refere ao campo de projeto de bombas. uma bomba centrífuga multiestágio com dois fluxos paralelos de meio bombeado compreende uma carcaça que consiste em duas partes separadas, cada uma das quais contém impulsores e aparelhos de guia, e uma cobertura de pressão central montada entre as referidas partes da carcaça. um tubo de entrega é vertical e orientado centralmente. a bomba inclui adicionalmente uma cobertura de transferência de extremidade para transferir fluido da primeira parte da carcaça para a segunda parte através de canais de transferência fornecidos integralmente com a cobertura de pressão e a cobertura de transferência. os impulsores estão dispostos na primeira e segunda partes da carcaça de modo a serem opostos um ao outro em relação à cobertura de pressão central. a primeira parte da carcaça compreende um tubo de sucção horizontal e um tubo de descarga vertical, que estão dispostos no lado de acionamento da bomba e são configurados na forma de uma peça fundida individualmente. o tubo de descarga é conectado por um tubo de transferência a uma câmara anular na cobertura de pressão central. a invenção visa simplificar a instalação, montagem e reparo da bomba em um ambiente operacional, reduzindo o comprimento da tubulação da bomba e permitindo a desmontagem e reparo da extremidade úmida da bomba sem desconectar as tubulações de sucção e descarga.
