Abstract
The utility model discloses an electric fuel pump core. Seven concave inclined-face grooves (3a) are evenly distributed in the outer circumference of a fuel inlet end cover (3), notches (1a) which are the equal to the concave inclined-face grooves (3a) in number and correspond to the concave inclined-face grooves (3a) in position are formed in the right end of a main case (1), the notches (1a) are connected together with the concave inclined-face grooves (3a) through radial cold extruding in a riveting mode and the left end of the main case (1) is provided with an inward-edge-rolling opening-contacting structure (1b) and a fuel outlet end cover (2) and the fuel inlet end cover (3) are formed through cold extruding. In the structure, the contacting faces of the fuel inlet end cover and the fuel outlet end cover are attached tightly and reliable, and therefore the product quality is high; the strength of the fuel inlet end cover and the strength of the fuel outlet end cover are high and the surface quality is good.
Description
Technical field
The utility model relates to the pith in engine fuel system---electric fuel punp, is specifically related to the pump cored structure of electric fuel punp.
Background technique
The required pressure of electric fuel punp pump core work is mainly to fit tightly generation by fuel-displaced end cap and oil inlet end lid, if two laminating end faces of fuel-displaced end cap and oil-feed end cap are gapped or laminating is not tight, the required pressure of oil-fired system will reduce, thereby causes product failure.
In addition, fuel-displaced end cap and oil-feed end cap adopt aluminium alloy compression casting moulding, part can crack at press casting procedure medium casting, bubble, be out of shape, owe casting, the defects of die casting such as surface roughness is poor, strength character is poor, utilization ratio is low.
Model utility content
The purpose of this utility model be solve gapped between fuel-displaced end cap and oil-feed end cap in electric fuel punp pump core, laminating is not tight, and into and out of problems such as oily end cap intensity are low, of poor quality.
For this reason, the technological scheme that the utility model adopts is: a kind of electric fuel punp pump core, comprise casing (1), be arranged on motor (5) and core group (6) in casing (1), described motor (5) is positioned at the left side of core group (6), described core group (6) comprises from left to right the coaxial fuel-displaced end cap (2) arranging successively, impeller (4) and oil-feed end cap (3), and the left side of the right side of fuel-displaced end cap (2) and oil-feed end cap (3) fits together, key is: on the excircle of described oil-feed end cap (3), be evenly equipped with seven recessed surface grooves (3a), the right-hand member of described casing (1) is provided with recessed surface groove (3a) quantity and equates, the otch (1a) that position is corresponding, and be riveted together by Radial Cold Extrusion and recessed surface groove (3a), the left end of described casing (1) is provided with interior crimping closing-in structure (1b), described fuel-displaced end cap (2) and oil-feed end cap (3) adopt cold extrusion shaped.
By covering at oil inlet end, seven recessed surface grooves are set, the otch corresponding with recessed surface groove is set on casing, after oil-feed end cap normally press-fits, utilize the cutter equate with recessed surface groove quantity simultaneously radial contraction push motor casing, and be passed to the oil-feed end cap face groove that concaves.The rigidity resilience of otch rear motor shell is little, reaches similar plastic deformation effect, makes oil-feed end cap and the laminating of fuel-displaced end cap surface of contact more closely reliable, and quality of product is guaranteed.In addition, adopt cold extrusion shapedly into and out of oily end cap, its surface compact degree is high, without bubble, transition nature.
Further, the surface of described casing (1) is provided with zn-ni alloy deposits (1c).Adopt zn-ni alloy deposits, principle is sacrificial anode protection admiro.Admiro, by electrochemical method, adsorbs by heavy current impact electrolysis under the effect of metal surface active ion, at workpiece surface, forms the very negative admiro protective film of a kind of current potential.Decay resistance is very strong, can stand the corrosion of bio-fuel-oil (M100, E100), meets the requirement of using in bio-fuel-oil (M100, E100).
The beneficial effects of the utility model are: the oil-feed end cap of this structure and the laminating of fuel-displaced end cap surface of contact are closely reliable, reliable operation; High into and out of oily end cap intensity, surface quality is good.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
In conjunction with Fig. 1---shown in Fig. 4, a kind of electric fuel punp pump core, mainly by casing 1, the motor 5 and the core group 6 that are arranged in casing 1 form.
On the excircle of oil-feed end cap 3, be evenly equipped with seven recessed surface groove 3a, the otch 1a that the right-hand member of casing 1 is provided with recessed surface groove 3a quantity equates, position is corresponding, and be riveted together by Radial Cold Extrusion and recessed surface groove 3a, thereby realized the fixing of casing 1 right-hand member and oil-feed end cap 3, guaranteed that fuel-displaced end cap 2 fits tightly with the both ends of the surface of oil-feed end cap 3 together with.Fuel-displaced end cap 2 and oil-feed end cap 3 adopt cold extrusion shaped.
The left end of casing 1 is connected with working of plastics, is therefore provided with interior crimping closing-in structure 1b.
Preferably, the surface of casing 1 is provided with zn-ni alloy deposits 1c.Preferably, the nickel content in zn-ni alloy deposits 1c, lower than 10%, is preferably 7-9%; Zn-ni alloy deposits 1c adopts plating form to be attached to the surface of casing 1, then carries out passivation, forms one deck passivation protection film.
Claims (2)
1. an electric fuel punp pump core, comprise casing (1), be arranged on motor (5) and core group (6) in casing (1), described motor (5) is positioned at the left side of core group (6), described core group (6) comprises from left to right the coaxial fuel-displaced end cap (2) arranging successively, impeller (4) and oil-feed end cap (3), and the left side of the right side of fuel-displaced end cap (2) and oil-feed end cap (3) fits together, it is characterized in that: on the excircle of described oil-feed end cap (3), be evenly equipped with seven recessed surface grooves (3a), the right-hand member of described casing (1) is provided with recessed surface groove (3a) quantity and equates, the otch (1a) that position is corresponding, and be riveted together by Radial Cold Extrusion and recessed surface groove (3a), the left end of described casing (1) is provided with interior crimping closing-in structure (1b), described fuel-displaced end cap (2) and oil-feed end cap (3) adopt cold extrusion shaped.
