Abstract
The utility model relates to an electric fuel pump which comprises a shell, wherein fuel inlet and outlet components, an armature component and a magnetic shoe component are arranged in the shell; the fuel inlet component is installed at one end of the shell; the other end relative to the fuel inlet component is provided with the fuel outlet component; the armature component is arranged between the fuel inlet component and the fuel outlet component; the magnetic shoe component is arranged on the armature component; the shell at the fuel inlet component end is provided with an fuel inlet channel; and the fuel inlet channel is provided with a filtering mechanism. The technical scheme provided by the utility model can filter out fuel pollutants and reduce the failures, thereby having the good effect of prolonging the service life.
Description
Technical field
The utility model relates to a kind of electric fuel punp.
Background technique
The electric fuel oil pump structure is made up of the pump housing, permanent magnet motor and shell three parts.The permanent magnet motor energising promptly drives pump housing rotation, and fuel oil is sucked from filler opening, and the electric fuel punp inside of flowing through extrudes from oil outlet again, supplies with the oil-fired system fuel feeding.Cooling action is played to the armature of permanent magnet motor in the fuel oil electric fuel punp inside of flowing through.
Electric fuel punp is made very accurately, so they are very sensitive to pollutant, even very little pollutant also is easy to the permanent damages electric fuel punp.The main cause that causes fuel pump to break down too early is owing to occurred the fuel oil pollution thing of picture dust, iron rust or incrustation scale and so in the oil-fired system.Fuel tank and oil-fired system inevitably produce above-mentioned fuel oil pollution in the process of using; And electric fuel punp is also contaminated easily in production test procedure; To selling and using and bring very big negative effect.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of ability filter fuel pollutant, reduces fault, thus the electric fuel punp that increases the service life.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of electric fuel punp, comprise housing, and be equipped with in institute's housing into and out of oily assembly, armature assembly and magnetic shoe assembly; Said oil-feed assembly is installed in housing one end; With respect to the other end of oil-feed assembly fuel-displaced assembly is installed, between said oil-feed assembly and the fuel-displaced assembly armature assembly is set, the magnetic shoe assembly is set on armature assembly; The housing of said oil-feed assembly end is provided with oil input channel, and said oil input channel is provided with filtering mechanism.
Through adopting technique scheme, filtering mechanism is set on oil input channel, prevent that effectively the fuel oil pollution thing from getting in the fuel pump, avoid the contaminants fuel pump, thereby reduce fault, prolonged working life.
The utility model further is set to: said filtering mechanism comprises filter screen, and said filter screen is installed between the outlet and oil-feed assembly of oil input channel, and said filter screen radially covers the outlet of said oil input channel, and filter screen is fixedly connected with inner walls.Through this setting, prevent that effectively the fuel oil pollution thing from getting in the fuel pump reliable operation.
The utility model also further is set to: the inlet of said oil input channel is provided with the oil-feed guard shield.Through this setting, oil-feed guard shield and filter screen play the effect of double protection, make the utility model work more reliable.
The utility model has the advantages that: filtering mechanism is set on oil input channel, prevents that effectively the fuel oil pollution thing from getting in the fuel pump, avoid the contaminants fuel pump, thereby reduce fault; Inlet at oil input channel is provided with the oil-feed guard shield, and oil-feed guard shield and filter screen play the effect of double protection, thereby has prolonged the working life of the utility model.
Below in conjunction with Figure of description and embodiment the utility model is further described.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Referring to accompanying drawing 1, the disclosed electric fuel punp of the utility model comprises housing 5; Be equipped with in institute's housing 5 into and out of oily assembly 4,1; Armature assembly 2 and magnetic shoe assembly 3, said oil-feed assembly 4 is installed in housing 5 one ends, with respect to the other end of oil-feed assembly 4 fuel-displaced assembly 1 is installed; Between said oil-feed assembly 4 and the fuel-displaced assembly 1 armature assembly 2 is set; Magnetic shoe assembly 3 is set on armature assembly 2, and the housing 5 of said oil-feed assembly 4 ends is provided with oil input channel 7, and said oil input channel 7 is provided with filtering mechanism.
The filtering mechanism of present embodiment preferably; Said filtering mechanism comprises filter screen 6; Said filter screen 6 is installed between the outlet 71 and oil-feed assembly 4 of oil input channel 7, and said filter screen 6 radially covers the outlet 71 of said oil input channel 7, and filter screen 6 is fixedly connected with housing 1 inwall.The advantage of this technological scheme is that simple in structure, cost is low, can prevent effectively that the fuel oil pollution thing from getting in the fuel pump, avoids the contaminants fuel pump, thereby reduces fault, increases the service life.
For making work more reliable, longer service life, present embodiment preferably, import 72 places of said oil input channel 7 are provided with oil-feed guard shield 8.The advantage of this technological scheme is that oil-feed guard shield 8 and filter screen 6 play the effect of double protection.
In the present embodiment into and out of oily assembly 4,1, armature assembly 2 and magnetic shoe assembly 3 just no longer narrated for the technology that those skilled in the art knew, present embodiment.
The foregoing description is to the specific descriptions of the utility model; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection domain, the technician of related domain according to the content of above-mentioned model utility the utility model is made some nonessential improvement and adjustment all falls within the protection domain of the utility model.
