A ring-type second anode made of metal material is arranged outside the pump shell; an additional power supply is arranged between the first anode and the second anode; an oil-discharging one-way valve is made of rubber component that is made by dissolving alcohol resistant fuel; the surface of a carbon brush line that is integrated with a carbon brush frame is provided with electrostatic coating of polytetrafluoroethylene; the anode circuit connecting point is sealed by alcohol fuel resistant, gasoline resistant and corrosion resistant material; the impeller component can be a thickened impeller. The double-anode electronic-injection fuel pump can adopt gasoline and alcohol fuel, facilitate the cold starting of the engine, and overcome the air resistance; thus the service life of the fuel pump is prolonged.
Description
Technical field
The utility model relates to the fuel pump that a kind of electronic fuel injection engine is used, and particularly can be applicable to gasoline, methanol and alcohol powered automobile, the electrospray fuel oil pump structure of anti-alcohols corrosion.
Background technique
Because rising steadily of oil price, alternative fuel has become the task of top priority.Aalcohols fuel is meant the fuel combination of liquid fuel such as methyl alcohol, ethanol or itself and gasoline, when being used as automotive fuel, have exhaust gas discharged pollute little, advantage such as thermal efficiency height, price are low.But, in electric field, be easy to make active the increasing of charged ion in the fuel, and then metal film is produced non-spontaneous redox reaction because Aalcohols fuel has very strong molecular polarity.By a large amount of electric-spraying fuel pumps that has damaged is carried out anatomic observation, find that anodic attack is very serious, if existing electronic fuel pump is not carried out technological improvement, will have a strong impact on the popularization of alcohols alternative fuel.
The model utility content
In order to overcome the deficiency that prior art can not satisfy the alcohols alternative fuel, the purpose of this utility model is to provide a kind of double anode electrospray fuel pump with anti-Aalcohols fuel electrochemical corrosion.
For achieving the above object, the utility model is taked following design proposal:
A kind of double anode electrospray fuel pump, it comprises pump case, the carbon brush holder assembly, rotor assembly, the magnetic shoe assembly, the pump impeller assembly, fuel-displaced one-way valve, install a ring-like second plate of making of metallic material additional in the pump case outside, have on the ring-like second plate can with the conductor terminal that the oil pump working power+the 12V terminal links to each other, oil pump working power+12V terminal is used as the first anode, between the first anode and second plate, be connected an additional supply, wherein the positive pole of additional supply links to each other with second plate by lead, and the negative pole of additional supply links to each other with the first anode by lead.Fuel-displaced one-way valve is selected the rubber parts of the swelling of anti-the Aalcohols fuel for use, and electrostatic spraying is carried out with polytetrafluoroethylene in the surface of the carbon brush line of carbon brush holder assembly, also can adopt flexible carbon fiber lead to come the carbon brush line of Alloy instead of Copper metal.The all tie points of anode circuit seal with anti-Aalcohols fuel and fuel-proof corrosion-resistant material, and the pump impeller assembly is selected the thickening type impeller.
Double anode electrospray fuel pump of the present utility model by above-mentioned processing after, when engine running, because the current potential of second plate is higher than the first anode all the time, electrochemical reaction mainly occurs in the second plate place, so can effectively weaken the generation of first anode corrosion, prolong oil pump working life; Fuel-displaced one-way valve is selected the rubber parts of the swelling of anti-the Aalcohols fuel for use, can guarantee effectively that fuel supply system keep-ups pressure, so that realize cold start-up smoothly; The anode circuit tie point is by effective closure, and the polytetrafluoroethylene film on the carbon brush line surface of carbon brush holder assembly effectively guardwire is not subjected to the erosion of Aalcohols fuel and does not influence the flexibility of carbon brush line, so can effectively weaken the generation of anodic attack; The thickening type impeller can effectively improve the flow of fuel pump, thereby has overcome the air-resistance phenomenon of Aalcohols fuel at torridity summer.
The beneficial effects of the utility model are: can satisfy the use of gasoline, Aalcohols fuel simultaneously, help engine cold-start, overcome vapour lock, prolong the working life of fuel pump.
