Description
Technical field
The utility model relates to a kind of electric fuel punp, is specifically related to a kind of motorcycle externally-built type electric fuel punp.
Background technique
Domestic motorcycle engine system adopts Carburetor to carry out fuel oil dispensing basically, and efficient is low, is unfavorable for environmental protection.In recent years, the electric injection system on the automobile has extended on the motorcycle, replaces the carburetor structure that falls behind, because motorcycle tank is less, under the situation that does not change the motorcycle oil box structure, adopt the externally-arranged type electric fuel punp more reasonable, can be widely used in various vehicles.At present, Chinese patent CN200920155690.2 discloses a kind of external electric fuel punp, its structure is mainly by forming into and out of hydraulic fluid port, housing and oil transfer pump, wherein oil transfer pump comprises roller pump and direct current generator, and direct current generator link press span, carbon brush component, stator module, armature assembly, feed cover and oil-feed nut are formed, and oil transfer pump is installed in the housing as a whole assembly, like this, it is relatively large that the boundary dimension of housing is made, and it is big to take up room, and structure is not compact.In addition, feed cover place at oil transfer pump is equipped with safety valve, can open automatically as the excessive safety valve of the pressure at oil outlet place, play the release effect, because safety valve is positioned at housing, can not adjust the size of hydraulic fluid port pressure in use at any time, therefore can not use as pressure regulator valve, fuel oil circulates in pump, can not flow back to fuel tank.When using this pump, need in pipeline, connect pressure regulator valve in addition, the complex structure after feasible the installation, structure is not compact.
Summary of the invention
In order to overcome the not compact and big deficiency that takes up room of existing externally-arranged type electric fuel oil pump structure, the utility model provides a kind of motorcycle externally-built type electric fuel punp, and this motorcycle externally-built type electric fuel punp has compact structure, little, the low characteristics that reach high working efficiency of noise take up room.
The technical solution of the utility model is: this motorcycle externally-built type electric fuel punp comprises shell, rotor, magnet steel, wing pump and feed cover, wing pump is made up of the pump housing, impeller and pump cover, one end of rotor utilizes the pump housing to support as revolution and links to each other with impeller in the wing pump, the two ends of shell are respectively equipped with feed cover and rear end cover assembly, feed cover is provided with filler opening, magnet steel and rotor are installed in the rear end cover assembly, are provided with axle bed in the rear end cover assembly, the other end of rotor places in the axle bed; The rear end cover assembly is provided with oil discharge passage and oil outlet, on the sidewall of oil discharge passage pressure regulator valve is installed.
Described impeller is a turbine structure.
Described pressure regulator valve is fixed by snap ring.
The beneficial effects of the utility model are: owing to take such scheme, magnet steel and rotor are installed in the rear end cover assembly, make direct current generator, housing and rear end cover assembly form an integral body, simplify the structure; Simultaneously, adopted pressure regulator valve to be installed in design on the rear end cover assembly, pressure regulator valve both can have been set up the fuel pressure of oil outlet, can play the effect of safety valve again, unnecessary fuel oil directly flow back into fuel tank, compact structure from pressure regulator valve, it is little to take up room, and space availability ratio is very high.
