Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the impeller of the good water pump of a kind of water conservancy diversion effect.
The purpose of this utility model realizes by following technical proposal: a kind of impeller of water pump, comprise the body in plate-like, the side of described body be provided with some blades and described blade perpendicular to described body, it is characterized in that, the thickness of the blade that described blade is curved and described is thinning gradually from outer end toward the inner, and the outer end of described blade is mutually concordant with the outer side wall of described body.
Because the thickness of the blade of this impeller is thinning gradually from outer end toward the inner, enable the outer end of blade bear larger thrust, simultaneously because its inner is thin, have current and guide effect preferably, enable the impeller of this water pump have good water conservancy diversion effect.
In the impeller of above-mentioned a kind of water pump, the sidewall of the outer end of described blade has the guide surface one of inclination.The sidewall of the outer end of blade is provided with the guide surface one of inclination, is convenient to guide current along blades flows, has good guide effect.
In the impeller of above-mentioned a kind of water pump, the sidewall of the inner of described blade is provided with the guide surface two of inclination.The inner of blade is provided with the guide surface two of inclination, makes the current at the middle part entering into impeller have good guide effect.
In the impeller of above-mentioned a kind of water pump, the inner of described blade is provided with highly successively toward the step that the inner side of blade declines, and the sidewall of described step is equipped with guide surface two.By arranging above-mentioned step, blade is made to have good drainage.
In the impeller of above-mentioned a kind of water pump, the middle part of the another side of described body is coaxially provided with the attachment post of protrusion, described attachment post is provided with the attachment hole run through, the another side of described body is also provided with some stiffening ribs, and the inner of described stiffening rib is all connected with described attachment post.By arranging attachment post, being convenient to impeller and being connected with rotating shaft, by arranging stiffening rib, improving the intensity of this impeller, make use more reliable.
In the impeller of above-mentioned a kind of water pump, in the attachment hole of described attachment post, be provided with keyway.In attachment hole, keyway is set, is convenient to this impeller and is connected with rotating shaft, have and connect conveniently advantage.
Compared with prior art, the impeller of this water pump has the following advantages:
1, the thickness due to the blade of this impeller is thinning gradually from outer end toward the inner, enables the outer end of blade bear larger thrust, simultaneously because its inner is thin, has and guides effect preferably, enable the impeller of this water pump have good water conservancy diversion effect to current;
2, the sidewall of the outer end of blade is provided with the guide surface one of inclination, is convenient to guide current along blades flows, has good guide effect;
3, the inner of blade is provided with highly successively toward the step that the inner side of blade declines, and the sidewall of step is equipped with guide surface two, makes blade have good drainage effect.
