Abstract
The utility model discloses a kind of fuel pump impeller, the circle blade comprising the impeller plate and arrange near impeller plate cylindrical, the both sides end face of the impeller plate is provided with equalizing orifice and guiding gutter, equalizing orifice and guiding gutter pairing are arranged, equalizing orifice is positioned at guiding gutter, equalizing orifice is the through hole of through impeller plate both sides end face, it is characterized in that: described equalizing orifice is elliptical aperture, and the long axis direction of elliptical aperture is identical with the radial direction of the impeller plate; Described blade is wooden dipper type blade, and the blade face, front and back of described blade all has wooden dipper shape cambered surface.The both sides end face of the impeller plate of the present utility model is operationally more not easy to wear, improves working life; There is the advantage increasing oil pump flow, reduce operation of oil pump electric current and noise simultaneously.
Description
[technical field]
The utility model relates to a kind of fuel pump impeller being applied to automobile electric fuel pump.
[background technique]
At present, the structure of the fuel pump impeller of automobile electric fuel pump is generally: the circle blade comprising the impeller plate and arrange near impeller plate cylindrical, the both sides end face of the impeller plate is provided with equalizing orifice and guiding gutter, equalizing orifice and guiding gutter pairing are arranged, equalizing orifice is positioned at guiding gutter, and equalizing orifice is the through hole of through impeller plate both sides end face.In said structure, equalizing orifice is all circular hole, under the prerequisite that equalizing orifice area is certain, equalizing orifice is certain at impeller plate radial dimension in the radial direction, equal the diameter of circular hole, and the radial width of guiding gutter is a bit larger tham the radial dimension of circular hole, the radial width of guiding gutter is also little in this case, so the both sides end face of the impeller plate is more easy to wear, affect the working life of fuel pump impeller; In addition, blade is all adopt straight line type blade, and namely the blade face, front and back of blade is linear, the impeller of straight line type blade under comparable conditions, if it is very difficult to increase oil pump flow, unless strengthened operation of oil pump electric current, but the extra work of oil pump can be caused to bear, and operating noise is also large.
[summary of the invention]
In view of the deficiency of background technique, the purpose of this utility model aims to provide a kind of fuel pump impeller improving working life, increase oil pump flow, reduce operation of oil pump electric current and noise.
The utility model is implemented by the following technical programs:
A kind of fuel pump impeller, the circle blade comprising the impeller plate and arrange near impeller plate cylindrical, the both sides end face of the impeller plate is provided with equalizing orifice and guiding gutter, equalizing orifice and guiding gutter pairing are arranged, equalizing orifice is positioned at guiding gutter, equalizing orifice is the through hole of through impeller plate both sides end face, it is characterized in that: described equalizing orifice is elliptical aperture, and the long axis direction of elliptical aperture is identical with the radial direction of the impeller plate.
In technique scheme, equalizing orifice is elliptical aperture, under the prerequisite that equalizing orifice area is certain, the long axis direction size of elliptical aperture can be larger than Circularhole diameter, so after the radial direction of the long axis direction with the impeller plate that arrange elliptical aperture is consistent, equalizing orifice will strengthen in the size of radial direction, and the radial width of corresponding guiding gutter also can increase, so the both sides end face of the impeller plate is operationally more not easy to wear, improve the working life of fuel pump impeller.
As preferably, described blade is wooden dipper type blade, and the blade face, front and back of described blade all has wooden dipper shape cambered surface.After adopting technique scheme, blade makes wooden dipper type blade into by original straight line type blade, and wooden dipper type blade compares straight line type blade, can increase oil pump flow, but under comparable conditions, can reduce operation of oil pump electric current, also just reduces operating noise simultaneously.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the circumference sectional view of the utility model along blade neutral position.
[embodiment]
As shown in the figure, fuel pump impeller of the present utility model, the circle blade 2 comprising the impeller plate 1 and arrange near the impeller plate 1 cylindrical, the both sides end face of the impeller plate 1 is provided with equalizing orifice 3 and guiding gutter 4, equalizing orifice 3 and guiding gutter 4 match and arrange, and equalizing orifice 3 is positioned at guiding gutter 4, and equalizing orifice 3 is the through hole of the through impeller plate 1 both sides end face, described equalizing orifice 3 is elliptical aperture, and the long axis direction of elliptical aperture is identical with the radial direction of the impeller plate 1; Described blade 2 is wooden dipper type blade, and the blade face, front and back of described blade 2 all has wooden dipper shape cambered surface 5.
Fuel pump impeller of the present utility model, equalizing orifice is elliptical aperture, and make the both sides end face of the impeller plate operationally more not easy to wear, blade is wooden dipper type blade, enables oil pump augmented flow, reduces operating current and noise.
