Abstract

resumo patente de invenção: "bomba de fluxo livre". a presente invenção refere-se a uma bomba de fluxo livre compreendendo um impelidor (11, 22, 33) com uma base de impelidor que é constituída por um lado dianteiro (14, 5, 24) de um corpo de cubo (12, 23) projetando no centro do impelidor (11, 22, 33) e por uma superfície de disco (18, 28) localizada mais profundamente do que o lado dianteiro (14, 24) do corpo de cubo (12, 23) e alcançando uma circunferência externa do impelidor com sua profundidade máxima. a superfície de disco (18, 28) é fornecida com paletas (19, 29, 34) compreendendo lados dianteiros de paleta abertos (20, 30, 35) adjacentes ao corpo de cubo (12, 23) em sua extremidade interna e se estendendo a partir daí para a circunferência externa do impelidor (11, 22, 33). para evitar o acúmulo de material na frente do impelidor (11, 22, 33), é sugerido que pelo menos dentro de um terço interno de seu raio, a base do impelidor não seja localizada mais profundamente com relação à extremidade interna dos lados dianteiros de paleta (20, 30, 35) do que no máximo um sexto da diferença de altura (h) entre a extremidade interna dos lados dianteiros de paleta (20, 30, 35) e a profundidade máxima da superfície de disco (18, 28).
