The utility model discloses traditional impeller oil feed structure has been replaced for the structure of its oil feed mechanism is more firm, intensity is higher, and can effectively improve its life.
Description
Technical Field
The utility model relates to a fuel pump equipment, the long-life fuel pump body of concretely relates to.
Background
The fuel pump is the part of a motor vehicle engine fuel feeding, wherein the fuel pump mainly includes the pump body, the oil cup, the pump body is placed in the oil cup, when using, place the oil cup in the oil tank, fuel in the oil tank can enter into the oil cup, later the pump body is squeezed into the fuel in the oil cup and is realized the fuel supply in the engine, traditional fuel pump body all realizes the extraction of fuel through impeller mechanism, but discover in the in-service use process, the impeller takes place the card of impeller groove in long-time use process easily and dies, warp, fracture etc. its actual strength is relatively poor, life is not long.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a simple structure is provided, reasonable in design has replaced traditional impeller oil feed structure for the structure of its oil feed mechanism is more firm, intensity is higher, and can effectively improve its life's the fuel pump body.
Therefore, the utility model discloses an adopt following scheme to realize:
long-life fuel pump body, including the shell body the inside rotor that is provided with of shell body be provided with the magnetic shoe between rotor and the shell body the one end of shell body is provided with the upper end cover, be provided with nozzle, its characterized in that on the upper end cover: the other end of shell body is provided with the oil feed subassembly, the oil feed subassembly includes housing and lower housing, goes up to enclose out the oil space between housing and the lower housing go up the housing and be provided with between housing and the lower housing and rotate the wheel, it is connected with the rotor to rotate the wheel, the outer fringe that rotates the wheel is provided with the dogtooth outwards with extending, is provided with the ring between two adjacent dogteeth, go up and seted up out the oil groove on the housing, be provided with the oil feed tank down on the housing, the oil feed tank aligns with the oil inlet of shell body bottom.
The oil inlet groove and the oil outlet groove are eccentrically arranged.
Adopt above-mentioned technical scheme, the utility model discloses an advantage does: through the cooperation that sets up rotation wheel and ring, can rotate the oil feed tank department production negative pressure of taking turns the pivoted while at the lower housing, and then it is supreme to extract the fuel in the oil cup, in the oil space of walking that the lower housing encloses, later extrude by the oil groove of last housing again, extrude the fuel in the pump body and spout from the nozzle, traditional impeller oil pumping structure has been replaced, its overall structure's intensity is higher, be difficult for taking place to warp in long-time use, can guarantee the extraction of fuel better, and promote its life.
Drawings
The utility model discloses there is following figure:
fig. 1 is a cross-sectional view of the present invention;
FIG. 2 is a structural diagram of the outer side of the upper cover shell of the present invention
FIG. 3 is a view showing the structure of the outer side of the lower casing of the present invention;
fig. 4 is a structural diagram of the inner side of the lower cover shell of the present invention.
Detailed Description
As shown in the figures, the long-life fuel pump body disclosed by the utility model comprises an outer shell 2, a rotor 4 is arranged inside the outer shell 2, a magnetic shoe 3 is arranged between the rotor 4 and the outer shell 2, an upper end cover 1 is arranged at one end of the outer shell 2, an oil injection port 13 is arranged on the upper end cover 1, an oil inlet component is arranged at the other end of the outer shell 2, the oil inlet component comprises an upper cover 5 and a lower cover 7, an oil outlet space is enclosed between the upper cover 5 and the lower cover 7, a rotating wheel 6 is arranged between the upper cover 5 and the lower cover 7, the rotating wheel 6 is connected with the rotor 4, convex teeth 9 are arranged on the outer edge of the rotating wheel 6 in an outward extending way, a circular ring 8 is arranged between two adjacent convex teeth 9, an oil outlet groove 10 is arranged on the upper cover 5, an oil inlet groove 11 is arranged on the lower cover 7, the oil inlet groove 11 is aligned with an oil inlet, the centrifugal negative pressure extraction and extrusion of fuel oil are more suitable.
The utility model discloses a fuel pump body, through setting up the cooperation of rotating wheel 6 and ring 8, can rotate wheel 6 pivoted while in the 11 departments of oil feed tank of housing 7 produce the negative pressure down, and then extract supreme with the fuel in the oil cup, in the oil space of walking that the housing encloses down, later extrude by the oil groove 10 of last housing 5 again, extrude the fuel in the pump body and spout 13 from the nozzle, traditional impeller oil pumping structure has been replaced, its overall structure's intensity is higher, be difficult for taking place to warp in long-time use, can guarantee the fuel extraction better, and promote its life.
