Description

Heat monitoring formula double filtration fuel filter

Technical field

The present invention relates to filtering systems, are specifically related to a kind of fuel filter.

Background technique

Currently, fuel filter is single filter core single layer filter mode, the fuel oils such as gasoline or diesel oil are realized and are filtered, are not had Included heating device, more not to the detection method of fuel oil temperature.Colder places some for the north, fuel oil exist The risk temporarily condensed needs certain heating to facilitate fuel oil and thaws in time, obtains and is switched in time or starts vehicle.

Summary of the invention

It is an object of the invention to overcome the shortcomings of above-mentioned technology, and provide it is a kind of the fuel oil of filtering can be heated, The good heating monitoring formula double filtration fuel filter of strainability.

The purpose of the present invention is realized by following technical solution: heating monitoring formula double filtration fuel filter, including Filter core, shell, the filter core are mounted on filter block for two pieces and realize while filtering, and the filter core includes being arranged from outside to inside Level-one filter material and second level filter material, the level-one filter material be INVENTIONPaper filter mode, the second level filter material be fiber filament filter type； Heater is housed on the housing and at the strain position of filter core, is filled on the housing and in the side edge of heater There is temperature sensor.

After structure of the invention, two pieces filter core while, is filtered, and it is significant to improve fuel filter performance, filter effect； The fuel oil of filtering is suitably heated in the setting of heater, and carries out oil temperature monitoring by temperature sensor, is maintained at fuel oil Within the scope of applicable temperature, facilitate fuel oil and thaw in time, to make the normal operation and protection engine of filter, mentions significantly High working efficiency, ensure that the safety traffic of vehicle.

Detailed description of the invention

Below by way of drawings and embodiments, present invention is further described in detail.

Fig. 1 is mounting structure schematic diagram of the invention.

Fig. 2 is the top view of Fig. 1.

Fig. 3 is the structural schematic diagram of the filter core (any one) in Fig. 1.

Specific embodiment

Referring to figs. 1 to Fig. 3, the heating that the present invention is applied to automobile monitors formula double filtration fuel filter, including filter core 2, shell 7, the filter core 2 are that two pieces (in the shell 7 and laterally side by side) realizes mistake simultaneously on filter block 1 and to fuel oil Filter (when oil inlet enter two filter cores simultaneously, the fuel-displaced rear oil duct of two filter cores communicates), on the shell 7 and in filter core (wherein one It is a) strain position at be equipped with heater 5.The filter core 2 includes that (being arranged from outside to inside) level-one filter material 21 and second level are filtered Material 22 (and central tube, end cap).

Temperature sensor 3 (generally not close to flowline 4) is housed on the shell 7 and in the side edge of heater 5, To carry out real-time monitoring to the fuel oil temperature in filtering.The level-one filter material 21 is that INVENTIONPaper filter mode (realizes that level-one is common Coarse filtration), the second level filter material 22 is fiber filament filter type (realizing the special thin filtering of second level).Wherein, the temperature passes Sensor 3 and heater 5 are electrically connected with the temperature control device of vehicle motor；The shell 7 and filter block 1 can be made of one formula knot Structure；The external oil inlet pipe 6 of one upper lateral part of the shell 7 and to two pieces filter core simultaneously fuel feeding, the shell 7 (or filter block 1) it is another The external flowline 4 (between two pieces filter core) in side, the flowline 4 (in filter block and are extended to outer by oil discharge passage 41 In shell or only in filter block) it is docked simultaneously with the oil outlet of two pieces filter core.

The present invention is made of double filtering system, breaks the filter mode of previous single filter core, it is ensured that strainability.When When two pieces filter core (filtering simultaneously) can work normally, filter efficiency is far longer than the filter efficiency of a filter core, reduces Engine is because oil-free or oily less and the case where cannot start.All by synthetic material secondary filtration mode system inside the filter core At, be capable of handling as low as 4 μm of diameter of fuel impurity, water separative efficiency can reach 95% or more, can be dispersed fuel (especially bavin Oil) in particle coalescence be in biggish water droplet, to promote water-oil separation, protect multiple spot injection system from combustion to the maximum extent The abrasion of particle and moisture in oil.There is temperature automatically controlled function simultaneously, can detect the height of fuel oil temperature: when fuel oil flows through heating Device, when temperature sensor detects that the too low possibility of oil temperature condenses, temperature control device automatically turns on heater；When oil temperature is more than normal value When temperature control device heater can be automatically closed again, to protect the normal operation of engine and filter, substantially increase work Efficiency realizes full-automation.

Claims (1)

1. heating monitoring formula double filtration fuel filter, including filter core (2), shell (7), it is characterised in that: the filter core (2) It is mounted in for two pieces on filter block (1) and realizes while filtering, the filter core (2) includes the level-one filter material being arranged from outside to inside (21) and second level filter material (22), the level-one filter material (21) are INVENTIONPaper filter mode, and the second level filter material (22) is fiber filament mistake Filter mode；Heater (5) and the side edge in heater (5) are housed on the shell (7) and at the strain position of filter core Equipped with temperature sensor (3).
