Abstract

"Pá OCA PARA TURBINA OU BOMBA HIDRáULICA". Um rotor para uma turbina ou bomba hidráulica abrange um cubo e uma quantidade de pás que se estendem radialmente em volta do cubo em intervalos espaçados. Cada pá inclui um canto interno fixado no cubo e um canto externo periférico, um canto de entrada e um canto oposto de saída, e uma superfície curvada de sução e uma superfície curvada oposta de pressão. Uma das pás é fabricada de um elemento curvado do lado de pressão e um elemento curvado do lado de sução, fixados um com o outro. O elemento do lado de pressão inclui uma porção da superfície curvada de pressão e uma primeira superfície interna oposta. O elemento curvado do lado de sução, inclui uma porção da superfície curvada de sução e uma segunda superfície interna oposta. As primeira e segunda superfícies internas estão voltadas uma para a outra e uma porção da primeira superfície interna é distanciada de uma porção da segunda superfície interna para formar uma cavidade dentro da pá. Um método de fabricar a pá oca também está descrito."Hollow blade for turbine or hydraulic pump". A rotor for a turbine or hydraulic pump comprises a hub and a number of blades that extend radially around the hub at spaced intervals. Each paddle includes an inner corner attached to the hub and a peripheral outer corner, an inlet corner and an opposite outlet corner, and a curved suction surface and an opposing pressure curved surface. One of the blades is made of a pressure side bent element and a suction side bent element fixed together. The pressure side member includes a portion of the pressure bent surface and an opposite first inner surface. The curved suction side member includes a portion of the curved suction surface and an opposite second inner surface. The first and second inner surfaces face each other and a portion of the first inner surface is distanced from a portion of the second inner surface to form a cavity within the blade. A method of making the hollow blade is also described.
