Abstract
The invention discloses a fuel pump with a long full life circle. The fuel pump is characterized by comprising a wiring body, a plug component, an outer wall, a rotor, an oil outlet body, blades, an end cover body, a pump top, a sheet body, tile-shaped parts and an oil inlet device, wherein the pump top and the outer wall are riveted and fixed; the wiring body and the plug component are pressed into the pump top; the tile-shaped parts are positioned on front and rear sides of the rotor; the sheet body is pressed between the two tile-shaped parts and are used clamping the tile-shaped parts; one end of the rotor is inserted into the oil outlet body; the oil inlet device is positioned between the blades and the end cover body. The fuel pump with the long full life circle is powered on smoothly, and the quality of the product is excellent in.
Description
Technical field
The present invention relates to a kind of vapour fuel pump, relate in particular to the fuel pump that a kind of Life cycle is long.
Background technique
In at present common fuel pump, centered by the structure of its wiring cylinder, hole is through hole, when this makes wiring cylinder and brush welding, scolding tin is not only stayed the peripheral impact rosin joint that also there will be attractive in appearance, and when welding use soldering flux, during welding, be easy to along with soldering flux and brush wire are toward dirty, become very hard after making brush wire cooling.After this wiring body packs product into, there will be brush in brush hole bullet not out or eject less than 1/3rd, such product can no electric circuit, and the life-span is short.The outer wall of its existing product adopts aluminium outer wall in addition, and aluminium outer wall is in fuel tank High Temperature High Pressure power in the situation that, and the elongation percentage of outer wall is high.Originally there is variation in good product interiors of products structure after work a period of time, and it is very fast, the most obvious in summer especially that the gap change between turnover oiled-plate method and blade causes flow pressure to decline greatly, had a strong impact on the Life cycle of fuel pump.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of energising smooth and easy, the long fuel pump of Life cycle of good quality of product.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
The fuel pump that a kind of Life cycle is long, it is characterized in that, it comprises wiring body, plug-assembly, outer wall, rotor, goes out oil body, blade, end cover body, pump top, lamellar body, shoe and oil feeding device, pump head knob part and outer wall riveted are fixed, wiring body and plug-assembly are pressed in pump top, and shoe is positioned at the both sides, front and back of rotor, and lamellar body is pressed in the middle of two shoes and blocks shoe, the centre of oil body is inserted out in one end of rotor, and oil feeding device is between blade and end cover body.
Described lamellar body, rotor, go out oil body, blade, oil feeding device and end cover body and be positioned at outer wall.
Described wiring body comprises wiring cylinder, spring body and brush, and wiring cylinder has a center hole, and spring body is arranged in this center hole, and one end of brush is fixed through spring body and wiring cylinder.
Compared with prior art, the beneficial effect that the present invention has is:
When welding brush, wiring cylinder of the present invention is stood upside down be placed in heating frock and heat, to in the center hole of wiring cylinder, add appropriate sunlight soldering flux to fuse into appropriate tin silk, by (brush wire is cut into needed length in advance) in the center hole of the stretching insertion wiring of the wire on brush cylinder, with tweezers taking-up, put into cooling frock cooling, screw in spring body, such welding has solved scolding tin and has stayed the wiring cylinder peripheral impact possibility that occurs rosin joint that solved again attractive in appearance, and scolding tin can up not run along with brush wire, retained the original state of brush wire, having solved wiring body packs into and there will be brush after product bullet is not out or eject the situation less than 1/3rd in the brush hole, can extend the life cycle of product, improve the acceptance rate of the quality of product of knowing clearly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fuel pump that a kind of Life cycle of the present invention is long.
Fig. 2 is the structural representation of wiring body in the fuel pump that a kind of Life cycle of the present invention is long.
In figure, be labeled as: wiring body 1, plug-assembly 2, outer wall 3, rotor 4, go out oil body 5, blade 6, end cover body 7, pump top 8, lamellar body 9, shoe 10, oil feeding device 1l, wiring cylinder 12, spring body 13 and brush 14.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure l, fuel pump of the present invention comprises wiring body 1, plug-assembly 2, outer wall 3, rotor 4, go out oil body 5, blade 6, end cover body 7, pump top 8, lamellar body 9, shoe 10 and oil feeding device 1l, pump top 8 and outer wall 3 riveteds are fixed, cylindrical assembly 1 and plug-assembly 2 are pressed in pump top 8, shoe 10, lamellar body 9, rotor 4, go out oil body 5, blade 6, oil feeding device II and end cover body 7 are positioned at outer wall 3, shoe 10 is positioned at the both sides, front and back of rotor 4, lamellar body 9 is pressed in the middle of two shoes 10 and blocks shoe 10, the centre of oil body 5 is inserted out in one end of rotor 4, oil feeding device 11 is between blade 6 and end cover body 7.
When the present invention installs, pump top 8 is contained on outer wall 3, plug-assembly 2 and wiring body l are contained on pump top 8, then successively by shoe 10, lamellar body 9, rotor 4, go out oil body 5, blade 6, oil feeding device II, end cover body 7 and pack in outer wall 3.The material of outer wall adopts steel, such as No. 10 steel, No. 10 steel are carbon constructional quality steels that a kind of carbon content is lower, and the elongation percentage of steel and aluminium contrast are much lower, and heat resisting and pressure resisting is also much higher than aluminium, so greatly improved the Life cycle of fuel pump product.
As shown in Figure 2, wiring body l comprises wiring cylinder 12, spring body 13 and brush 14, wiring cylinder 12 has one for the center hole of blind hole, spring body 13 is arranged in this center hole, one end of brush 14 is fixing with wiring cylinder 12 through spring body 13, when welding brush, wiring cylinder l2 is stood upside down be placed in heating frock and heat, to in the center hole of wiring cylinder, add appropriate sunlight soldering flux to fuse into appropriate tin silk, by (brush wire is cut into needed length in advance) in the center hole of the stretching insertion wiring of the wire on brush 14 cylinder, with tweezers taking-up, put into cooling frock cooling, screw in spring body 13, such welding has solved scolding tin and has stayed the wiring cylinder peripheral impact possibility that occurs rosin joint that solved again attractive in appearance, and scolding tin can up not run along with brush wire, retained the original state of brush wire, having solved wiring body packs into and there will be brush after product bullet is not out or eject the situation less than 1/3rd in the brush hole, also can not cause the no electric circuit of product, the problem that life-span is short.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the above embodiment's variation, modification, all will drop within the scope of claim of the present invention.
