In sum, there is the technical problem that working life is low and cost is high in existing roller type fuel pump.
The model utility content
The purpose of this utility model is to provide a kind of roller type fuel pump, to solve the technical problem that roller type fuel pump in prior art working life is low and cost is high.
For achieving the above object, the utility model provides a kind of roller type fuel pump, comprise pump case, go out font, armature, pump chamber and oil-feed seat, go out the end that font is connected to pump case, armature and pump chamber are arranged in the pump case, armature with go out font and be connected, pump chamber is connected with armature, the oil-feed seat is connected to the other end of pump case.This pump chamber further comprises axle sleeve, oil-feed clamping plate, stator, rotor, plurality of rollers, fuel-displaced clamping plate and plastics riveting column, and stator is arranged between oil-feed clamping plate and the fuel-displaced clamping plate, and the oil-feed clamping plate are connected by the riveted joint of plastics riveting column with fuel-displaced clamping plate; Be arranged in the stator, rotor is provided with some grooves rotor eccentricity, and roller is arranged in the groove, and is provided with teflon coatings on the rubbing surface of stator and roller, and teflon coatings is electroplated with roller with stator respectively and is connected; Axle sleeve is arranged in whole pump chamber, respectively with oil-feed clamping plate, rotor and fuel-displaced clamping plate socket.
According to the described roller type fuel pump of the utility model preferred embodiment, this fuel pump also comprises a blade, and this blade is arranged in the oil-feed seat, and is connected with armature.
Compared with prior art, the utlity model has following advantage:
(1) all is provided with wear-resisting Teflon layer on the rubbing surface of the stator of this fuel pump and roller, reduced the attrition of stator and roller, wear-resisting property is good, improved the working life of fuel pump, simultaneously, avoid the matching gap of the stator that causes because of loss and roller excessive, improved the oil pressure performance of fuel pump.
(2) the oil-feed clamping plate of this fuel pump and fuel-displaced clamping plate adopt the riveted joint of plastics riveting column, and adding man-hour can be directly by the injection molding riveted joint, and not only the plastics cost is low, and the waste product in the course of working also significantly reduces, and are with low cost.
(3) this fuel pump has increased oil pumping device in the oil-feed group is upright--blade, strengthened the function of pump oil, the efficient height of pump.
Description of drawings
Fig. 1 is the utility model roller type fuel oil pump structure sectional view;
Fig. 2 is the schematic perspective view of the utility model embodiment's pump chamber;
Fig. 3 is the exploded perspective view of the utility model embodiment's pump chamber;
Fig. 4 is the utility model embodiment's the roller and the scheme of installation of stator.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1 to Fig. 4, a kind of roller type fuel pump, comprise pump case 10, go out font 20, armature 30, pump chamber 40, blade 50 and oil-feed seat 60, go out the end that font 20 is connected to pump case 10, armature 30 and pump chamber 40 are arranged in the pump case 10, armature 30 with go out font 20 and be connected, pump chamber 40 is connected with armature 30, oil-feed seat 60 is connected to the other end of pump case 10, and blade 50 is arranged in the oil-feed seat 60, is connected to armature 30 ends.
In this example, pump chamber 40 comprises five rollers 405, and rotor 404 is provided with five grooves 4041.But, need to prove, the utility model does not limit the concrete quantity of roller 405 and groove 4041, in actual applications, the quantity of roller 405 and groove 4041 can design according to concrete needs, more than adopt just example of five rollers 405 and groove 4041, and be not used in qualification the utility model.In addition, in preferred embodiment of the present utility model, oil-feed clamping plate 402 and fuel-displaced clamping plate 406 can directly be riveted by injection molding.But the utility model is not limited thereto, and any oil-feed clamping plate 402 of can realizing all should drop in the protection domain of the present utility model by the Placement that 407 riveted joints of plastics riveting column are connected with fuel-displaced clamping plate 406 in the prior art.
