The other end for stating pouring chamber is water outlet side, and bolt fixing hole is additionally provided on the wheel hub.
Preferably, the blade to the thickness of edge part from being gradually reduced at center.
Preferably, the blade to the height of edge part from being gradually reduced at center.
Preferably, the back side panel is globoidal structure.
Preferably, axis hole is additionally provided on the wheel hub, the bolt fixing hole is communicated in axis hole.
Preferably, the base circle diameter (BCD) of the blade curve be 15.3mm circumscribed square involute, two of blade
The centre-to-centre spacing of involute is 1.5mm.
The technique effect and advantage of the utility model：
The utility model improves the flow regime of water pump internal flow by blade, is allowed to tend to more rationally, to reduce
The wadding stream mode of fluid, to reduce the input power of water pump, the cross section size of the water outlet side by reducing pouring chamber,
By compression outlet size, the pressure of pouring intracavity liquid is improved, is conducive to liquid and obtains larger issuing velocity from water outlet side,
So that motor in the state that power is identical, improves the lift of water pump, and it is reasonable for structure, extend the service life of water pump.
Description of the drawings
Fig. 1 is a kind of overlooking structure diagram of vehicle-mounted water pump vane of the utility model；
Fig. 2 is a kind of internal structure schematic diagram of vehicle-mounted water pump vane of the utility model.
In figure：1 wheel hub, 2 blades, 3 influent sides, 4 bolt fixing holes, 5 front side boards, 6 pouring chambers, 7 water outlet sides, 8 axis holes, 9
Back side panel.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figs. 1-2, a kind of vehicle-mounted water pump vane, including wheel hub 1 and the blade 2 for being weldingly fixed on 1 side of wheel hub, institute
It states and forms pouring chamber 6 between blade 2, the top of the pouring chamber 6 is the front side board 5 that blade 2 surrounds, under the pouring chamber 6
Side is the back side panel 9 that wheel hub 1 is formed, and one end of the pouring chamber 6 is communicated in influent side 3, the other end of the pouring chamber 6 jointly
For water outlet side 7, bolt fixing hole 4 is additionally provided on the wheel hub 1.
For the blade 2 from being gradually reduced to the thickness of edge part at center, 2 thickness of blade at center is larger, can be with
The structural strength for improving blade 2 is prevented from being mixed into sundries with flow from influent side 3 and be damaged to blade 2, is conducive to improve leaf
The service life of piece 2.
On the one hand the blade 2 is conducive to save material, another party from being gradually reduced to the height of edge part at center
Face, by the height for reducing blade 2 so that the height of pouring chamber 6 is also gradually reduced, and reduces the transversal of the water outlet side 7 of pouring chamber 6
Face size improves the pressure of liquid in pouring chamber 6 by compression outlet size, be conducive to liquid obtained from water outlet side 7 it is larger
Issuing velocity is conducive to improve pump head.
The back side panel 9 is globoidal structure, is conducive to the frictional force for reducing liquid, reduces hydraulic losses.
Axis hole 8 is additionally provided on the wheel hub 1, the bolt fixing hole 4 is communicated in axis hole 8, by the way that shaft is sleeved on axis hole 8
