Abstract
The utility model relates to a fuel filter, belonging to the technical field of fuel filtration. The fuel filter comprises a cylindrical upper housing and a cylindrical lower housing which are fused, annulated column-shaped filter paper arranged in the housing, an oil inlet pipe arranged at a top end cover of the upper housing and an oil outlet pipe communicated with an oil outlet of an inner ring of the filter paper, wherein the filter paper is fixed by fixed frames arranged at the two ends of the upper and the lower housings, and sealing rings are respectively arranged between the two fixed frames and the upper and the lower housings. The two ends of the filter paper of the fuel filter disclosed by the utility model are fixed through the fixed frames, the filter paper and the fixed frames are adhered by glue or filter paper grooves of the fixed frames are heated and melted by infrared rays for connecting the filter paper and the fixed frames together, so that the fixing and the sealing effects are good. The sealing rings are respectively arranged between the two fixed frames of the filter paper and the upper and the lower housings so as to separate fuel communicated with an oil inlet and the oil outlet, realize a good filtering effect of the fuel and enable the filtering efficiency to achieve 10 mu >= 90%.
Description
Technical field
The invention belongs to the fuel oil filtration art, particularly relate to a kind of fuel filter.
Background technique
In order to improve the working life of motor, reduce oil consumption and environmental pollution, more and more higher to the quality requirement of the gasoline that uses or diesel fuel.Therefore, fuel oil filtered by filter cleaner before being delivered to generator, thereby improved the purity of fuel oil.
Existing filter cleaner arranges filter paper in can, oil inlet and outlet is set on the shell, the two ends that filter paper is connected with shell do not seal or seal bad, the fuel oil that enters from filler opening will some be directly inputted into motor without Filter paper filtering through oil outlet, owing to have impurity in the gasoline, wearing and tearing to motor are larger, affect its working life.
Summary of the invention
For the technical problem of above-mentioned existence, the invention provides a kind of fuel filter, it is simple in structure, easy for installation.
To achieve these goals, technological scheme of the present invention is as follows:
Comprise welding the cylindrical shape upper and lower casing, place enclosure interior annulated column shape filter paper, place the upper shell top end cover filler opening, with filter paper in the oil outlet that is connected of ring, it is characterized in that: described filter paper is fixed by the fixing frame that is arranged on the upper and lower casing two ends, between two fixing frames and upper and lower casing, be respectively arranged with seal ring, separate and the fuel oil that is communicated with into and out of hydraulic fluid port.
Described upper shell top also is provided with metal terminal.
Described seal ring is nonwovens or seal rubber pad.
Described two fixed rack structures are identical, be symmetrical arranged, on it with the circular groove of putting filter paper.
Bonding by glue between described fixing frame and the filter paper.
By infrared rays fixing frame is melted rear and filter paper welding between described fixing frame and the filter paper.The present invention has following advantage:
Filter paper of the present invention two ends are fixed by fixing frame, between filter paper and the fixing frame by glue bonding or with infrared rays with fixing frame filter paper groove heat fused after, filter paper and fixing frame are linked together, fix, good sealing effect.Be respectively arranged with seal ring between filter paper two fixing frames and upper and lower casing, separate and the fuel oil that is communicated with into and out of hydraulic fluid port, make the fuel oil good filtration effect, its filter efficiency reaches 10 μ 〉=90%.The present invention is used for being built in the fuel oil pump assembly of fuel tank.
Filter cleaner can produce static in the oil strain process, the Capacity of long time integration produces static spark easily, can cause serious consequence.For this reason, the metal terminal that arranges on the upper shell of the present invention is used for deriving static in the housing.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Wherein: 1. lower shell body, 2. fixed base, 3. upper shell, 4. filler opening, 5. oil outlet, 6. metal terminal, 7. fixing frame, 8. filter paper, 9. seal ring.
Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
Embodiment 1: the present invention includes welding cylindrical shape upper shell 3, lower shell body 1, place enclosure interior annulated column shape filter paper 8, place the filler opening 4 of upper shell 3 top end covers, the oil outlet 5 that is connected with filter paper 8 interior rings, described filter paper 8 is fixing by the fixing frame 7 that is arranged on upper shell 3, lower shell body 1 two ends, be respectively arranged with seal ring 9 at two fixing frames 7 and upper shell 3,1 of lower shell body, separate the fuel oil that is communicated with filler opening 4, oil outlet 5.
Described upper shell 3 tops also are provided with metal terminal 6, to derive static in the housing.Described seal ring 9 is nonwovens, plays the effect of sealing.Described two fixing frames, 7 structures are identical, be symmetrical arranged, on it with the circular groove of putting filter paper 8.Bonding by glue between described fixing frame 7 and the filter paper 8.
When the present invention installs, filler opening 4 is connected with the oil outlet tube of fuel pump core, be provided with on the circumference by lower shell body 1 on fixed base 2 oil pump assys, flow into the fuel oil of filler opening 4 through fuel pump, enter into filter paper 8 along housing inner circumference direction, after filter paper 8 filtrations, flow out to motor from the oil outlet 5 that communicates with filter paper 8 interior rings.
Embodiment 2: this example and embodiment's 1 difference is: between described fixing frame 7 and the filter paper 8 with infrared rays with fixing frame filter paper groove heat welded, make the fixing and good sealing effects of filter paper 8.Described seal ring 9 is seal rubber pad, can reach sealing effect equally.
Claims (6)
1. fuel filter, comprise welding the cylindrical shape upper and lower casing, place enclosure interior annulated column shape filter paper, place the upper shell top end cover filler opening, with filter paper in the oil outlet that is connected of ring, it is characterized in that: described filter paper is fixed by the fixing frame that is arranged on the upper and lower casing two ends, between two fixing frames and upper and lower casing, be respectively arranged with seal ring, separate and the fuel oil that is communicated with into and out of hydraulic fluid port.
2. fuel filter according to claim 1, it is characterized in that: described upper shell top also is provided with metal terminal.
