| 摘要 |
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. |
