Abstract

um propulsor para bombas centrífugas possui um primeiro elemento de disco, disposto de forma funcional na direção da entrada, que é coaxial a e está voltada para um segundo elemento de disco, que é disposto de maneira funcional na direção de distribuição e é conectado rigidamente ao primeiro elemento de disco em virtude de uma série de palhetas espaçadas de forma angular e é fornecido de forma centralizada com um dispositivo para fixar a um eixo de transmissão. a particularidade da presente invenção reside no fato de o propulsor incluir uma série de aberturas formadas na região substancialmente periférica do segundo elemento de disco, entre os pares de palhetas adjacentes, substancialmente em áreas sujeitas à maior impulsão axial.
