Description
Technical field
The utility model relates to technical field of automobile accessories, and in particular to a kind of auto pump blade.
Background technique
Auto pump is that the mechanical energy of engine is passed to the machinery that fluid increases its kinetic energy and pressure energy, is engine
Important component in cooling system, and auto pump blade is the important part in auto pump.Auto pump blade holds at present
Cavitation phenomenons easily occur, the service life of auto pump can be reduced.
Utility model content
The purpose of this utility model is to provide a kind of auto pump blades, are easy hair to solve existing auto pump blade
The problem of raw cavitation phenomenons.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of auto pump blade, comprising: impeller cover and multiple blades；The center of impeller cover is equipped with for transmission shaft
The connecting hole passed through, multiple blade rings are fixed on the ipsilateral end face of impeller cover around connecting hole；Water is formed between adjacent blades
Road；The leading edge width of blade is greater than rear width, and the line style of two sides of blade is the hyperbolicity circular arc of S type, blade
The concave and convex direction of the hyperbolicity circular arc of two sides is consistent.
The blade inlet edge of the utility model is wider than rear, so that the sectional area Magnification of water channel reduces, is equivalent to water channel and enters
The pressure difference of area at mouthful, water channel exit and water channel inlet reduces, and avoids the appearance of cavitation phenomenons.Blade side is located at leaf
The up-front circular arc of piece can reduce the water velocity in water channel exit, reduce the pressure difference in water channel exit and water channel inlet, from
And avoid the appearance of cavitation phenomenons.
In addition, the leading edge of blade is wider than rear, the quality that blade integral edge quality is greater than center, blade rotation are allowed for
After can store energy, when water pump stops working, blade can work under the action of inertia, prevent the hair of backflow phenomenon
It is raw.
Further, the side of above-mentioned blade is greater than the song of the circular arc close to rear close to the radius of curvature of up-front circular arc
Rate radius.
Further, the side of above-mentioned blade is less than the circle formed with its radius of curvature close to the length of up-front circular arc
The 1/4 of perimeter.
The side wall of the blade of the utility model is less than the circle formed with its radius of curvature close to the length of up-front circular arc
The 1/4 of perimeter can prevent water flow from issuing in the exit of water channel 130 and be vortexed, influence the circulation of water flow.
Further, the two sides of above-mentioned blade are interior concave arc, and tangent with impeller cover.
The two sides of the blade of the utility model are interior concave arc, can reduce the hole pair generated due to cavitation phenomenons
The influence of blade.
Further, above-mentioned blade and impeller cover are integrally formed.
Further, the quantity of above-mentioned blade is 6.
The utility model has the following beneficial effects: width of the utility model by increase blade inlet edge, so that water channel
Sectional area Magnification reduce, and the line style of two sides of blade is the hyperbolicity circular arc of S type, to reduce water channel
The pressure difference in exit and water channel inlet effectively prevent the appearance of cavitation phenomenons.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the auto pump blade of the utility model；
Fig. 2 is the blade of the utility model and the cross section structure schematic diagram of impeller cover.
In figure: 100- auto pump blade；110- impeller cover；111- connecting hole；120- blade；130- water channel；140-
Interior concave arc.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Embodiment
Fig. 1 is please referred to, auto pump blade 100 includes impeller cover 110 and blade 120, the center of impeller cover 110
Equipped with connecting hole 111, connecting hole 111 and transmission axis connection, the quantity of blade 120 is 6, is evenly distributed on the outer of connecting hole 111
Side and the same side for being mounted on impeller cover 110 form water channel 130 between two neighboring blade 120.In the present embodiment, leaf
Piece 120 and 110 integrally casting shaping of impeller cover, can be improved 120 torque resistant ability of blade.
One end that blade 120 is located at 110 edge of impeller cover is leading edge, and one end positioned at the middle part of impeller cover 110 is
Rear.The leading edge width of blade 120 is greater than rear width, while making the quality at blade integral edge greater than the matter at center
Amount, making blade integrally is in flywheel form, and blade is whole when rotated, can store energy.Two sides of blade 120 are S
The hyperbolicity circular arc of type, two ipsilateral circular arcs of blade 120 are tangent, and the radius of curvature close to up-front circular arc is greater than close to rear
Circular arc radius of curvature, and the concave and convex direction of the hyperbolicity circular arc of two sides of blade 120 is consistent.Close to up-front circle
The length of arc is less than the 1/4 of the perimeter of the circle formed with its radius of curvature, prevents water flow from issuing whirlpool in the exit of water channel 130
Rotation, influences the circulation of water flow.
Referring to figure 2., the two sides of blade 120 are interior concave arc 140, and interior concave arc 140 and impeller cover 110
It is tangent.Due to the guide functions of interior concave arc 140, water flow can be guided to overturn along the surface of interior concave arc 140, reduced due to vapour
Direct impact of the hole of phenomenon generation to blade 120 is lost, to slacken the influence of cavitation phenomenons or avoid going out for cavitation phenomenons
It is existing.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
