DESIGN METHOD OF INTERNAL FLOW CHANNEL CROSS SECTION OF SINGLE CHANNEL PUMP IMPELLER

摘要

The present invention relates to a method for designing a large-area internal flow path of a single-channel pump impeller, and more particularly, to a large-area internal of a single-channel pump impeller to prevent a flow path from being clogged by wastewater containing bulky solids. It is about how to design the euro. The present invention comprises the steps of: a) deriving a design proposal of an impeller and a volute casing of a single channel pump; And b) varying the cross-sectional area of the inner flow path of the impeller while fixing the shape of the internal flow path of the volute casing and the height of the impeller designed according to the derived design proposal. Provides a large-area internal flow path design method.
