Abstract
The utility model relates to an alcohol corrosion resistance fuel pump used by an electric fuel injection engine. The oil-out check valve adopts the rubber parts which are swelling-proof to the alcohol fuel; the surface of the carbon brush line of the carbon brush shelf assembly is electrostatically sprayed by PTFE; the connecting point of anode circuit is sealed by anticorrosion material which is alcohol-resistance and gas-resistance; the pump wheel components adopt the thickened impellers. The utility model can satisfy the application of the gas and fuel of alcohols, is beneficial for the cooling start of the engine, overcomes the air-lock and prolongs the service life of the fuel pump.
Description
Technical field
The utility model relates to a kind of electronic fuel injection engine and uses fuel pump, particularly can be applicable to gasoline, the anti-alcohol corrosion of methanol and alcohol powered automobile electrospray fuel oil pump structure.
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.Because Aalcohols fuel has very strong molecular polarity, so be easy to metallic material is produced electrochemical corrosion.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 improved from production technology, 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 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 anti-pure electrospray fuel pump, it comprises pump case, carbon brush holder assembly, rotor assembly, magnetic shoe assembly, pump impeller assembly, fuel-displaced one-way valve, fuel-displaced one-way valve is selected the rubber parts of the swelling of anti-the Aalcohols fuel for use, 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.
The anti-pure electrospray fuel pump of the utility model by above-mentioned processing after because 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 effect of the anti-pure electrospray fuel pump of the utility model is: can satisfy the use of gasoline, Aalcohols fuel simultaneously, help engine cold-start, overcome vapour lock, prolong the working life of fuel pump.
Description of drawings
Accompanying drawing is the anti-pure electrospray vehicle fuel pump structure schematic representation of the utility model
Embodiment
Engaging drawings and Examples below further specifies the utility model.
Accompanying drawing is depicted as an embodiment of the anti-pure electrospray fuel pump of the utility model, this anti-pure electrospray fuel pump, it comprises pump case 1, carbon brush holder assembly 2, rotor assembly 3, magnetic shoe assembly 4, pump impeller assembly 5, fuel-displaced one-way valve 6, fuel-displaced one-way valve 6 is selected the rubber parts of the swelling of anti-the Aalcohols fuel for use, electrostatic spraying is carried out with polytetrafluoroethylene in the surface of the carbon brush line 11 of carbon brush holder assembly 2, also can adopt flexible carbon fiber lead to come the carbon brush line 11 of Alloy instead of Copper metal.Anode circuit tie point 7,8,9 will seal with anti-Aalcohols fuel and fuel-proof corrosion-resistant material, and pump impeller assembly 5 is selected thickening type impeller 10.
As shown in drawings, the working mechanism of the anti-pure electrospray fuel pump of the utility model is: because fuel-displaced one-way valve 6 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; Anode circuit tie point 7,8,9 is by effective closure, and the polytetrafluoroethylene film on carbon brush line 11 surfaces effectively guardwire be not subjected to the erosion of Aalcohols fuel and do not influence the flexibility of carbon brush line 11, so can effectively weaken the generation of anodic attack; Thickening type impeller 10 can effectively improve the flow of fuel pump, thereby has overcome the air-resistance phenomenon of Aalcohols fuel at torridity summer.
The anti-pure electrospray fuel pump of the utility model is owing to can satisfy the use of gasoline, Aalcohols fuel simultaneously, help motor cold start-up, overcome vapour lock, prolong working life of fuel pump, and technology is fairly simple, existing product is changed few, tissue that can be very fast is produced in batches, so can well guarantee the large-scale promotion of alcohols alternative fuel.
