Impeller for water pump with curved wing structure and water pump applied with the same

摘要

The present invention relates to an underwater impeller having a curved wing structure, and an underwater pump employing the same. More particularly, the present invention provides an impeller having a curved wing structure and connected to a driving motor installed in an underwater pump to be rotatable, the impeller including: a lower panel having an inlet such that water is introduced through driving of the driving motor installed in the underwater pump; an upper panel disposed on the upper side of the lower panel and connected to a rotary shaft of the driving motor installed in the underwater pump; and a wing part connecting an upper surface of the lower panel and a bottom surface of the upper panel, wherein one end of the wing part is disposed to be closer to the inlet and the wing part is curved outwards as it goes toward an opposite end thereof, and an underwater pump employing the same. The impeller for an underwater pump having a curved wing structure and an underwater pump employing the same according to the present invention may prevent foreign substances from being caught due to rotation of the impeller and may pump water by forming the curved wing part while connecting the lower panel and the upper panel and may improve a pumping efficiency of water by forming an outer surface of the wing part such that the wing part is curved and widening a contact area of water as compared with the wing part.
