Title (EN) IMPELLER HAVING CYLINDRICAL VANES
(FR) HÉLICE AYANT DES PALES CYLINDRIQUES

Abstract: front page image
(EN)The present invention relates to an impeller having cylindrical vanes, in which multiple hollow vanes are arranged into a spiral in one direction from the center of a base plate, such that the fluid introduced into a hollow housing flows into a water inlet port by means of the rotation of the impeller, and then the introduced fluid flows into inlet ports of the multiple vanes formed at the center of the base plate and is discharged through outlet ports of the multiple vanes, thereby minimizing friction between the impeller and the fluid and maximizing the head of a pump and efficiency. In addition, the impeller of the present invention is configured such that an outer surface of any one vane from among the plurality of vanes is spaced apart from an outer surface of another vane adjacent to said any one vane, so as to minimize the friction loss of the fluid flowing in a path other than the inlet ports. The base plate, the vanes, and the inlet ports are integrally formed so as to provide structural stability.
(FR)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.
(KO)본 발명은 베이스판의 중심으로부터 일방향으로 나선형을 그리며 형성되는 중공의 베인이 다수 형성되어 중공의 하우징 내부로 유입되는 유체가 임펠러의 회전에 의해 입수구로 유입되고, 유입된 유체는 베이스판의 중심부에서 형성되는 다수의 베인의 유입구로 유입되어 유출구로 배출됨으로써 유체와의 마찰을 최소화함과 동시에 펌프의 양정 및 효율을 극대화할 수 있는 원통형 베인을 포함하는 임펠러를 제공한다. 또한, 본 발명은 다수의 베인 중 어느 하나의 베인의 외주면과 어느 하나의 베인에 인접한 다른 하나의 베인의 외주면이 이격됨에 따라 유입구 이외로 흐르게 되는 유체와의 마찰 손실을 최소화하고 베이스판, 베인 및 유입구는 일체로 형성되어 구조적인 안정감을 줄 수 있는 원통형 베인을 포함하는 임펠러를 제공한다.
