Description
Technical field
The utility model relates to a kind of cooling motorcycle water pump impeller.
Background technique
At present, on market, existing huge discharge cooling motorcycle water occurs that engine cooling effect misses one's aim often, the cause that in the motor of its reason mainly huge discharge cooling motorcycle water, the pump water yield of water pump is on the low side, and in motor, the pump water yield of water pump and the impeller quantity of water pump and structure have relation.
Model utility content
In view of the above-mentioned problems in the prior art, main purpose of the present utility model is to address the deficiencies of the prior art, and the utility model provides the cooling motorcycle water pump impeller that a kind of pump water yield is large.
The utility model provides a kind of cooling motorcycle water pump impeller, comprise impeller body, the exterior edge face of described impeller body is evenly provided with multiple first blade, multiple second blade is evenly provided with between described adjacent first blade, the radius of described first blade is 23mm, the thickness of described first blade is 2.5mm, and the radius of described second blade is 22mm, and the center of described impeller body is provided with mounting hole.
Optionally, the diameter of described mounting hole is 11.8 ~ 12.3mm.
Optionally, the diameter of described mounting hole is 12mm.
Optionally, the shape of described first blade is formed by the arc transition that radius is 9.5mm.
Optionally, described multiple first blade is six the first blades, and described multiple second blade is six the second blades.
The utility model has the following advantages and beneficial effect: the utility model provides a kind of cooling motorcycle water pump impeller, by increasing by the second blade, effectively can improve the flow stream velocity distribution in impeller channel, the effect making the liquid stream near the first blade exit place non-working surface annex be subject to the second blade to add merit, therefore the separation in boundary layer and the generation of the separation of flow is effectively prevented, simultaneously owing to exporting the increase of total leaf number, increase head coefficient and can water-outlet quantity be increased, solving the problem that the huge discharge cooling motorcycle water water pump pump water yield is less than normal.
Accompanying drawing explanation
Fig. 1 is the structural representation of cooling motorcycle water pump impeller of the present utility model.
Embodiment
With specific embodiment, the utility model is further described below with reference to accompanying drawings.
As shown in Figure 1: a kind of cooling motorcycle water pump impeller of the utility model embodiment, comprise impeller body 1, the exterior edge face of described impeller body 1 is evenly provided with multiple first blade 2, multiple second blade 3 is evenly provided with between described adjacent first blade 2, the radius of described first blade 2 is 23mm, the thickness of described first blade 2 is 2.5mm, the radius of described second blade 3 is 22mm, the center of described impeller body 1 is provided with mounting hole 4, by increasing by the second blade 3, effectively can improve the flow stream velocity distribution in impeller channel, the effect making the liquid stream near the first blade exit place non-working surface annex be subject to the second blade to add merit, therefore the separation in boundary layer and the generation of the separation of flow is effectively prevented, simultaneously owing to exporting the increase of total leaf number, increase head coefficient and can water-outlet quantity be increased, solve the problem that the huge discharge cooling motorcycle water water pump pump water yield is less than normal.
As the preferred implementation of above-described embodiment, the diameter of described mounting hole 4 is 11.8 ~ 12.3mm.
As the preferred implementation of above-described embodiment, the diameter of described mounting hole 4 is 12mm.
As the preferred implementation of above-described embodiment, the shape of described first blade 2 is formed by circular arc 5 transition that radius is 9.5mm.
As the preferred implementation of above-described embodiment, described multiple first blade is six the first blades, and described multiple second blade is six the second blades.
Last it is noted that above-described each embodiment is only for illustration of the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in previous embodiment, or to wherein partly or entirely technical characteristics carry out equivalent replacement; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment's technological scheme of the utility model.
