Abstract
The utility model relates to a fuel filter, belonging to the technical field of fuel filtration. The fuel filter comprises an upper housing and a lower housing which are fused into a whole, annulated column-shaped filter paper arranged in the housing and an upper cover arranged at a top end cover of the upper housing, wherein an oil outlet communicated with an inner ring of the filter paper is arranged at the top end of the upper cover, an oil inlet is arranged on the side surface of the lower housing, and a power supply socket is further arranged on the upper cover. The two ends of the filter paper of the fuel filter disclosed by the utility model are fixed through 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. Sealing rings arranged on the fixed frames are positioned at the middle parts of the annular grooves containing the filter paper and in hermetic contact with the inner rings of the upper and the lower housings so as to separate fuel communicated with the oil inlet and the oil outlet, realize a good filtering effect of the fuel and enable the filtering efficiency to achieve 35mu>=90%. A metal terminal arranged on the upper housing of the fuel filter disclosed by the utility model is used for leading out static electricity in the housing so as to prevent electric capacity which is accumulated for a long time from being less prone to producing electrostatic spark.
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.Because long-term the use produces static easily in the filter body, 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:
The present invention includes welding all-in-one-piece upper and lower casing, place enclosure interior annulated column shape filter paper, place the loam cake of upper shell top end cover, the loam cake top is provided with the oil outlet that is connected with ring in the filter paper, the lower shell body side is provided with filler opening, also is provided with power socket covering.
Described filter paper is fixed by the fixing frame that is arranged on the upper and lower casing two ends, described two fixed rack structures are identical, be symmetrical arranged, on it with the circular groove of putting filter paper, on two fixing frames with respect to an end of upper and lower casing with seal ring, described seal ring places the circular groove middle part of placing filter paper, contacts with the upper and lower casing sealing, separates into and out of the fuel oil between hydraulic fluid port.
Described lower shell body end is provided with metal terminal.Described lower end also is provided with the return opening that is communicated with fuel tank.
Bonding by glue between fixing frame of the present invention and the filter paper.Perhaps, can use infrared rays with after the fixing frame filter paper groove fusing it to be linked together between described fixing frame and the filter paper.
Described loam cake is provided with to install to connect uses strut.
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.Decide according to the enclosure interior structure seal ring position that arranges with respect to an end of upper and lower casing on fixing frame, be positioned at the circular groove middle part of placing filter paper, contact with ring sealing in the 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 35 μ 〉=90%.
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 lower shell body of the present invention is used for deriving static in the housing.Return opening is used for unnecessary fuel oil is flow back into fuel tank.
Description of drawings
Fig. 1 is structural representation of the present invention.
