Abstract

"BOMBA CENTRìFUGA ACIONADA MAGNETICAMENTE DE BALANCEAMENTO HIDRáULICO". Uma bomba acionada magneticamente inclui um invólucro, uma concha de contenção fixa no invólucro, um eixo mecânico fixo na extremidade fechada da concha de contenção, um propulsor rotativo em torno do eixo mecânico dentro do invólucro e da concha de contenção e um acoplamento magnético preso de forma liberável no propulsor e rotativo em torno do eixo mecânico. A bomba também inclui um mancal traseiro posicionado entre o propulsor e o eixo mecânico que é rotativo em torno do eixo mecânico, e uma válvula de controle de empuxo que inclui um anel de pressão traseiro posicionado entre a concha de contenção e o mancal traseiro. Uma abertura da válvula de controle de empuxo é definida por um espaçamento variável entre o anel de pressão e o mancal traseiro.
