| description | The invention relates to an efficient water pump impeller. The efficient water pump impeller comprises an impeller body, an impeller cover and a pump chamber shell. The impeller cover is composed of an inner cover and an outer cover. Two curves of the inner sides of the radial sections of the inner cover and two curves of the inner sides of the radial sections of the outer cover are offset curves which are equal in distance, the shape of the inner cover and the outer cover is a rotating body formed by surrounding the axis of a water pump by the offset curves, and the water inlet end of the impeller is perpendicular to the water outlet of the impeller. Because the shape of the inner cover and the outer cover is the rotating body formed by surrounding the axis of the water pump by the offset curves, water resistance of the structure is greatly reduced, water entering a water pump chamber flows along the curved surfaces at a high speed, effect is improved, and the lift is accordingly improved. |
