Abstract

"BOMBA CENTRìFUGA COM ACIONAMENTO DE MOTOR DE RELUTâNCIA COMUTADA". Uma bomba centrífuga, particularmente do tipo de tubo de Pitot (12) é especificamente configurada e acoplada com um motor de relutância comutada (14) para provisão de características melhoradas de bombeamento e vantagens operacionais económicas no conjunto de bomba (26), incluindo a capacidade de se diminuir rapidamente a velocidade de bomba (por exemplo, de 100% para 10%) em segundos (isto é, de 3 a 6 segundos) e, da mesma forma, de se aumentar rapidamente (por exemplo, de 0% para 80% ou mais) em segundos (isto é, de 5 a 1o segundos), apesar das características de massa e inércia maiores de algumas bombas centrífugas. o conjunto de bomba da presente invenção também é configurado para prover uma área espacial menor, desse modo se tornando a bomba mais adequada para uma variedade mais ampla de aplicações do que o que estava previamente disponível para bombas de tubo de Pitot convencionais.
