To achieve these goals, technological scheme of the present invention is as follows:

A kind of electric fuel punp that is used for motorcycle, comprise flange bracket, pump core, pressure regulator, sieve box and rat tail, the pump core is fixed on first support of flange bracket, the pressure regulator filler opening is connected with pump core oil outlet, and be installed on second support of flange bracket, the filler opening end of pump core is connected with sieve box, is fixed with power socket on the flange bracket, is connected with the pump core by rat tail.

Described flange bracket is structure as a whole, and a side of its flange is second support that is used to that first support of pump core is installed and is used for the setting pressure regulator, and first support is two collars; Second support is a mounting platform, the pressure relief opening which is provided with the filler opening that is connected with pump core oil outlet, the oil outlet that is connected with motor and be connected with pressure regulator, constitute one communication type pipeline, on the mounting platform periphery, be provided with the installation buckle, have a plurality of gas pressure relief slots on the end face.Described sieve box is being equipped with nonwovens with the filler opening upper and lower end face that joins.

The present invention has following advantage:

The present invention is the part of motorcycle oil supply system, not only can provide high pressure stable fuel oil to motor, makes fuel oil fully burning in motor, reduces oil consumption, reduces exhaust emissions.

Flange bracket of the present invention is structure as a whole, and on the equal mounting flange support of pump core and pressure regulator, is provided with the one communication type pipeline that is used to connect motor, pump core, pressure regulator on flange bracket, and compact structure reduces parts, reduces cost.

The present invention is built in the fuel tank of motorcycle, save metal shell and with motor and fuel tank between the connecting pipeline of oil return, simple in structure, the saving raw material.

Sieve box of the present invention is being equipped with nonwovens with the filler opening upper and lower end face that joins, and is stronger than existing nylon net cloth strainability, guarantees the engine fuel cleaning, prolongs motor working life.

Embodiment

Below in conjunction with drawings and Examples the present invention is described in further detail.

Embodiment: as shown in Figure 1 and Figure 2, the present invention includes flange bracket 4, pump core 3, pressure regulator 6, sieve box 1 and rat tail 8, pump core 3 is fixed on first support 41 of flange bracket 4, pressure regulator 6 filler openings are connected with pump core 3 oil outlets, and be installed on second support 42 of flange bracket 4, the filler opening end of pump core 3 is connected with sieve box 1 by snap ring 2, is fixed with power socket 7 on the flange bracket 4, is connected with pump core 3 by rat tail 8.

Pressure regulator 6 of the present invention adopts existing structure, and model is LH8E6, is used for regulating the fuel pressure of pipeline.Be pipeline inner pressure pressure regulator 6 beginning pressure releases when exceeding nominal pressure, pressure regulator 6 cut out and allows the fuel oil of pump core 3 outputs replenish pipeline inner pressure rapidly when pipeline inner pressure reduced.

Pump core 3 structures that adopted among the present invention, as shown in Figure 6, comprise body shell 301, upper shell 312, lower shell body 306, place the rotor 309 in the body shell 301, two arc-shaped magnets 308, pump cover 307 and impeller 304, on, be respectively equipped with fuel outlet 315 and fuel filler 314 on the lower shell body, rotor 309 is general carbon brush rotor, place in the body shell 301, its rotor shaft 317 stretches out upper end cap 312 and pump cover 307 respectively, impeller 304 is installed on the rotor shaft 316 by bearing 303, be connected with the carbon brush 313 that is connected with lead terminal 305 on the rotor 309, fuel outlet 315 pipelines of upper shell 312 are provided with dual way check valve 310; Two arc-shaped magnets 308 are provided with on rotor 309 excircles, and and 309 of rotors have the gap; As shown in Figure 4,308 of described two magnet are respectively equipped with plastics fixing clamp 311 and spring fixing clamp 302, and plastics fixing clamp 311 is a spacer, is integrated on the upper shell 312, are used for two magnet 308 at interval; Lead terminal 305 is connected with external power supply.
