Abstract

La présente invention porte sur une hélice, qui a des pales cylindriques, dans laquelle de multiples pales creuses sont disposées sous la forme d'une spirale dans une direction à partir du centre d'une plaque de base, de telle sorte que le fluide introduit dans un boîtier creux s'écoule dans un orifice d'entrée d'eau à l'aide de la rotation de l'hélice, après quoi le fluide introduit s'écoule dans des orifices d'entrée des multiples pales formées au centre de la plaque de base, et est déchargé à travers des orifices de sortie des multiples pales, de façon à minimiser ainsi le frottement entre l'hélice et le fluide et à maximiser ainsi la chute de pression d'une pompe et le rendement. De plus, l'hélice selon la présente invention est configurée de telle sorte qu'une surface externe de n'importe quelle pale parmi la pluralité de pales est espacée vis-à-vis d'une surface externe d'une autre pale adjacente à ladite quelconque pale, de façon à rendre au minimum la perte de charge due au frottement du fluide s'écoulant dans une trajectoire autre que les orifices d'entrée. La plaque de base, les pales et les orifices d'entrée sont formés d'un seul tenant de façon à produire une stabilité structurelle.
