Description
Technical field
The invention belongs to the cooling system of automobile engine, and in particular to the water pump of automobile engine, more particularly to
A kind of hyperbolicity Water-pump impeller of automobile.
Background technology
Impeller is the part for comparing core in pump class product, and its blade portions is a more complicated curved-surface structure,
Whether the design of blade wheel structure meets hydrodynamic characteristic, influences the height of the operating efficiency of water pump and the number of energy expenditure,
Because prismatic blade design causes easily to produce backflow or whirlpool inside water pump, therefore auto pump is mostly arc shaped blade at present, arc
Blade ring is fixed on wheel disc around connector, easy to process, but cavitation-resistance is poor, the service life of water pump blade it is low, it is necessary to
Often change blade.
The content of the invention
The purpose of the present invention is by setting blade construction, improving the anti-cavitation performance and hydraulic efficiency of auto pump, originally
Invention provides a kind of hyperbolicity Water-pump impeller of automobile.
The technical scheme is that：A kind of hyperbolicity Water-pump impeller of automobile, including several are arranged on hub disk
Impeller blade, described blade originate in impeller disk radius from inside to outside 1/3 at, described blade is hyperbolicity structure,
Including the second section that the outside first segment in the center of circle and the center of circle are inside；The curvature of described first segment is smaller than the second section, and first segment
Length be 2 times of the second section.
Further, 3 pressure releasing holes are arranged with described hub disk, described pressure releasing hole is arranged on 2 blades
Between second section.
The beneficial effects of the invention are as follows：This Water-pump impeller of automobile enters according to the flow and pressure demand of engine-cooling system
Row design, is determined after being analyzed using CFD, by the blade construction of uniqueness, improves the anti-cavitation performance and waterpower of auto pump
Efficiency.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
In figure：1 is first segment, and 2 be the second section, and 3 be pressure releasing hole.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Such as Fig. 1, a kind of hyperbolicity Water-pump impeller of automobile, including several are arranged on the impeller blade on hub disk, institute
The blade stated originate in impeller disk radius from inside to outside 1/3 at, described blade is hyperbolicity structure, including the center of circle is outside
The second section 2 of first segment 1 and the center of circle inwardly；The curvature of described first segment 1 is 2 smaller than the second section, and the length of first segment 1 is the
2 times of two sections 2.
3 pressure releasing holes 3 are arranged with described hub disk, described pressure releasing hole 3 is arranged on 2 sections of blade second 2
Between.
Cavitation principle：When the pressure for vaporization at a temperature of the absolute pressure for pumping liquid drops at that time, liquid is in this place
Start wild flower and produce steam formation bubble, when this bubble is reached at high pressure, bubble pressure-rupturable, liquid matter while rupture
Point will occur mutually to hit and form water attack with high speed impact filling hole.Thus drawing prevents pump cavitation from occurring most
Whole condition is the pressure for vaporization of the coolant at a temperature of pump intake pressure is greater than at that time, by formula Q=AV, PV=
NRTA/Q, it is the pressure at import of water pump impeller end to draw P=nRTA/Q, wherein P, and n is the amount of material, and R is mol gas constant,
T is open type temperature, and A is the area of the entrance point of blade 1, and Q is flow, and the area on the inclined-plane 4 of the entrance point of blade 1 processing is more than originally
The area A increases of the area of the entrance point end of blade 1, the i.e. entrance point of blade 1, so keeping the constant feelings of the original performance of water pump
Under condition so that the pressure P increases at import of water pump impeller end, so as to improve water pump anti-cavitation performance.
This Water-pump impeller of automobile present invention is simple in construction, and cost is cheap.According to the flow and pressure of engine-cooling system
Demand is designed, and is determined after being analyzed using CFD, by the blade construction of uniqueness, improves the anti-cavitation performance of auto pump
And hydraulic efficiency.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above, for this area skill
For art personnel, it is clear that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing substantially from the present invention spirit or
In the case of essential characteristic, the present invention can be realized in other specific forms.Which point therefore, no matter from the point of view of, all should incite somebody to action
Embodiment regards exemplary as, and be it is nonrestrictive, the scope of the present invention by appended claims rather than on state
Bright restriction, it is intended that all changes fallen in the implication and scope of the equivalency of claim are included in the present invention
It is interior.Any reference in claim should not be considered as to the involved claim of limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
