Embodiment
Core of the present utility model is to provide a kind of diesel engine and fuel filter thereof, the compact structure of this fuel filter, and functional reliability is high.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 4 and Fig. 5, Fig. 4 provides a kind of structural representation of the fuel filter for diesel engine for the utility model; Fig. 5 is the structural representation of another angle of fuel filter shown in Fig. 4.
Please also refer to Fig. 6, the generalized section of the cleaner case that Fig. 6 is fuel filter.
In the receiving cavity of cleaner case 11, be provided with electrically operated fuel pump 14 and controller 13, controller 13 and electrically operated fuel pump 14 are electrically connected to, and controller 13 can be controlled electrically operated fuel pump 14 work.Wherein, controller 13 is positioned at end cap 111 1 sides of cleaner case 11, and the electric connection line of being convenient to controller 13 is drawn.
In above-described embodiment, controller 13 is built in cleaner case 11, compared to controller being hung in background technique to the mode of cleaner case outside, obviously, in the utility model, by controller 13 being built in to the mode of cleaner case 11, make controller 13 can access the encirclement protection of cleaner case 11, avoided installation process middle controller 13 to be subject to foreign object collision and damaged; In addition, because controller 13 is built in cleaner case 11, controller 13 be built in equally cleaner case 11 in electrically operated fuel pump 14 between the wire harness that is electrically connected to be also arranged in cleaner case 11, certainly also avoided described electrical connection wire harness to be collided by foreign object, thereby guaranteed the reliability of electrical connection between controller 13 and electrically operated fuel pump 14, and then improved the functional reliability of fuel filter 10.
For above-described embodiment, can also make further improvement.
Compared to anodal in background technique, by screw, fix, negative pole adopts the mode of bonding, above-mentioned employing power connector 16 is realized the mode that controller 13 is connected with diesel engine main circuit, can realize on the basis of quick grafting, can guarantee the validity that circuit connects, and during assembling, without extra assistant tool, reduced installation time, improved efficiency of assembling.
Should be appreciated that power insert is connected with the circuit connecting wire of controller 13, power supply fitting is connected with the main circuit connecting line of diesel engine, is also feasible, can reach above-mentioned technique effect equally.
Incorporated by reference to Fig. 6 and Fig. 7, wherein, Fig. 7 is the schematic diagram of electrically operated fuel pump and cleaner case supporting structure in Fig. 6.
Further, the inwall of cleaner case 11 has the draw-in groove 11c coordinating with the end of electrically operated fuel pump 14, electrically operated fuel pump 14 is supported in cleaner case 11 by described draw-in groove 11c, in background technique, by overhang, be supported in cleaner case, in this embodiment, cancelled overhang, electrically operated fuel pump 14 is directly connected in the draw-in groove 11c of cleaner case 11, owing to having saved the arrangement space of overhang, so dwindled the axial dimension of cleaner case 11, made the overall structure of fuel filter 10 compacter; In addition, because the whole end of electrically operated fuel pump 14 is supported by cleaner case 11, supporting structure compared to overhang, this kind of mode increased the Area of bearing of electrically operated fuel pump 14, can strengthen the freedom from vibration of electrically operated fuel pump 14, the carbon brush abrasion amount while contributing to reduce its motor internal work.
It is pointed out that draw-in groove 11c certainly cannot individualism, the signal in Fig. 7 is just for the supporting structure of sake of clarity electrically operated fuel pump 14.
Also it should be noted that, the other end of electrically operated fuel pump 14 is still by the stent support of being located in cleaner case 11.
Further, fuel filter 10 also comprises heater 15, and heater 15 is located at the other end of filter housing 12, and is connected with controller 13 circuit, that is whether controller 13 can work by control heater 15.
When in low temperature environment, in the situation of fuel oil wax deposition, can start heater 15 work, by the fuel oil solution wax of wax, so, can get through whole low pressure oil way, guarantee that oil circuit is unobstructed, promote the low-temperature startup performance of diesel engine.
Wherein, heater 15 is connected and also can adopts connector assembly to slotting mode with the circuit of controller 13, is similar to the Placement of above-mentioned controller 13 and diesel engine main circuit, repeats no more here.
Except above-mentioned fuel filter, the utility model also provides a kind of diesel engine, comprises that fuel supply system is unified to be located at the fuel filter in described fuel oil supply system, and described fuel filter is the fuel filter described in above-mentioned arbitrary embodiment.Because above-mentioned fuel filter has above-mentioned technique effect, the diesel engine with this fuel filter also has identical technique effect, repeats no more herein.
During diesel engine starting, because controller 13 is connected in diesel engine main circuit by power connector 16, so controller 13 can receive external start signal, thereby control electrically operated fuel pump 14 work, fuel oil, by filler opening 11a suction filter body 12, after the filtration of filter housing 13, is flowed out from oil outlet 11b, after reaching predetermined operating time section, controller 13 can be controlled electrically operated fuel pump 14 and quit work; After diesel engine runs well, electrically operated fuel pump 14 quits work, and fuel oil can enter filter housing 12 by the bleed off circuit by cleaner case 11 under the pressure-acting of pressure duct; In the course of the work, if the fuel oil temperature in filter housing 13 during lower than predefined value, controller 13 can control heater 15 work, until fuel oil temperature is not less than predefined value.
Above diesel engine provided by the utility model and fuel filter thereof are described in detail.Applied specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
