Abstract
The utility model provides a kind of Water-pump impeller of automobile, comprise wheel disc, attachment hole, blade, described blade is equidistantly distributed in described wheel disc circumferentially, the curved structure of described blade, the cross-section area of described blade is reduced to leaf top gradually by blade root, and the thickness of described blade is increased to trailing edge gradually by leading edge.The blade design of this impeller increases the torque resistant ability of impeller to greatest extent, reduce liquid around the acceleration of blade inlet edge and step-down simultaneously, reduce the vaporization of liquid to a certain extent, thus reduce the cavitation of impeller inlet place blade, improve working life and the efficiency of impeller.
Description
Technical field
The utility model relates to the cooling system of motor car engine, is specifically related to a kind of Water-pump impeller of automobile.
Background technique
Impeller is the part comparing core in pump series products, its blade portions is the curved-surface structure of a more complicated, whether the design of blade wheel structure meets hydrodynamic characteristic, affect the height of the working efficiency of water pump and the number of energy ezpenditure, because prismatic blade design causes inner easily generation of water pump to be refluxed or whirlpool, therefore auto pump mostly is arc shaped blade at present, arc shaped blade is fixed on wheel disc around connection mouth, easy to process, but cavitation-resistance is poor, the working life of water pump blade is low, needs often to change blade.
When the absolute pressure that liquid pumped by pump is less than the pressure for vaporization of liquid, liquid just starts vaporization, produce steam, form bubble, these bubbles with liquid flow forward to certain high pressure place time, the highly pressurised liquid around bubble causes bubble sharply reduce so that break, formed water attack, produce noise and vibration, show that centrifugal pump starts cavitation.Usual centrifugal pump is by the position of cavitation damage, near display blade inlet, then impeller outlet is extended down to, the particularly spot that produces behind of impeller and groove, time one length will make overcurrent lose and receive destruction, cause blade and the perforation of impeller front and rear cover plate time serious, even impeller breaks, and causes serious accident.
Model utility content
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: a kind of Water-pump impeller of automobile, comprise wheel disc, attachment hole, blade, described blade is equidistantly distributed in described wheel disc circumferentially, the curved structure of described blade, the cross-section area of described blade is reduced to leaf top gradually by blade root, and the thickness of described blade is increased to trailing edge gradually by leading edge.
Further, the pressure side of described blade and suction surface are all convexly curved along blade root to the direction on leaf top and upwards extend.
Further, the seamed edge of described Ye Ding both sides is that fillet is arranged.
Further, described blade number is 5, is provided with equalizing orifice between adjacent blades.
Further, be fixed with stiffening rib described blade root and described wheel disc joint, make between described blade root and described wheel disc in round-corner transition.
The advantage that the utility model has and beneficial effect are:
1, the cross-section area of blade of the present utility model is reduced to leaf top gradually by blade root, and blade is fixedly connected with wheel disc with maximum area, increases the torque resistant ability of impeller to greatest extent, makes in wheel rotation process more stable;
2, the thickness of blade is increased to trailing edge gradually by leading edge, reduces liquid around the acceleration of blade inlet edge and step-down, reduces the vaporization of liquid to a certain extent, thus reduce the cavitation of impeller inlet place blade, improve working life and the efficiency of impeller;
3, blade number is 5, suitably decreases the number of blade, alleviates the exclusion degree at vane inlet place.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. wheel disc, 2. attachment hole, 3. blade, 31. blade roots, 32. leaf tops, 33. pressure sides, 34. suction surfaces, 4. balance port, 5. stiffening rib.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated
As shown in Figure 1, the utility model provides a kind of Water-pump impeller of automobile, comprise wheel disc 1, attachment hole 2, blade 3, described blade 3 is equidistantly distributed in described wheel disc 1 circumferentially, the curved structure of described blade 3, is characterized in that: the cross-section area of described blade 3 is reduced to leaf top 32 gradually by blade root 31, and the thickness of described blade 3 is increased to trailing edge gradually by leading edge.The cross-section area of blade 3 is reduced to leaf top 32 gradually by blade root 31, and blade 3 is fixedly connected with wheel disc 1 with maximum area, increases the torque resistant ability of impeller to greatest extent, makes in wheel rotation process more stable; The thickness of blade 3 is increased to trailing edge gradually by leading edge, reduces liquid around the acceleration of blade 3 leading edge and step-down, reduces the vaporization of liquid to a certain extent, thus reduce the cavitation of impeller inlet place blade 3, improve working life and the efficiency of impeller
Further, the pressure side 33 of described blade 3 and the suction surface 34 of described blade 3 are all convexly curved along blade root 31 to the direction on leaf top 32 and upwards extend, and arc change curve can lead the flowing of liquid, reduces the resistance of liquid.
Further, the seamed edge of both sides, described leaf top 32 is that fillet is arranged.
Further, described blade 3 number is 5, is provided with equalizing orifice 4 between adjacent blades 3.Suitably decrease blade 3 number, alleviate the exclusion degree of blade 3 inlet; The stress surface 33 being arranged so that blade 3 of equalizing orifice 4 reduces with the pressure difference of the suction surface 34 of blade 3, makes wheel rotation more stable.
Further, stiffening rib 5 is fixed with described wheel disc 1 joint described blade root 31, make between described blade root 31 and described wheel disc 1 in round-corner transition, the setting of stiffening rib 5 adds the adhesive fastness between blade 3 and wheel disc 1, reduce the degree that blade root 31 is corroded, increase the working life of blade 3.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
