Abstract
The invention relates to a methanol fuel pump. The methanol fuel pump comprises a shell, wherein a motor and a pump head driven by the motor are arranged in the shell; a controller is fixed on the back surface of a casing of the motor; the controller and a stator winding arranged in the casing of the motor are packaged with the casing of the motor as a whole; a fuel leading port for flowing through fuel is left between the casing of the motor and the shell; the pump head comprises an impeller, a fuel inlet plate and a fuel outlet plate; and the impeller is clamped between the fuel inlet plate and the fuel outlet plate. The casing of the motor, the controller and the stator winding are packaged as a whole, so that the number and the area of parts directly contacted with the fuel in the fuel pump are reduced, the erosion effect of methanol on the fuel pump is reduced to the greatest extent, and the most important point is that the service life of the impeller can reach 4,000 hours or above 100,000 km to largely prolong the service life of the fuel pump after PPS plastics are improved.
Description
Technical field
The invention belongs to fuel pump technical field, being specifically related to a kind of take methyl alcohol as the methanol fuel pump of fuel.
Background technique
Methanol fuel pump is the critical component in automobile electronic fuel oil jet system, except providing the fuel oil needed for automobile power, also plays the effect of stable EFI system pressure, so key point that to be automobile working properly of the efficient and long lifetime of methanol fuel pump.In addition along with the minimizing of world petroleum resource, and it is non-renewable, the use of the use of novel energy, particularly recyclable fuel---methyl alcohol, brings a new revolution to vehicle fuel power, but methyl alcohol has extremely strong corrosivity, make general plastics can not for the methyl alcohol oil pump of M100, secondly the wearing and tearing in methyl alcohol of general plastics be very large, after being used in 48 hours, will skid in impeller central hole, flow straight line declines.
Be 201120065705.3 at application number, the applying date is 2011.03.15 " a kind of methanol tolerant fuel pump ", controller is arranged on outside the pump housing by this invention, therefore in use, this controller is not immersed among methyl alcohol, therefore just there is not the technical problem be corroded, ensure that the working life of fuel pump, although this invention can ensure that controller is not corroded, but impeller problem such as excessive wear in methyl alcohol cannot be solved, usually in use after 48 hours, impeller will damage, thus whole fuel pump will be scrapped, the life-span of fuel pump is still very short, in order to the working life of methanol fuel pump really can be increased substantially, just not only structurally change, more need more to become on material.
Summary of the invention
For the present situation of above-mentioned prior art, technical problem to be solved by this invention is the methanol fuel pump providing a kind of long service life.
The present invention solves the problems of the technologies described above adopted technological scheme: a kind of methanol fuel pump, include housing, motor is provided with and by motor-driven pump head in described housing, controller is fixed with after this motor housing, this controller is packaged as a whole together with the staor winding be arranged in motor housing and motor housing, leave the oil diverting port flow through for fuel oil between motor housing and housing, described pump head comprises impeller, oil-feed plate and goes out oiled-plate method, and this impeller is clipped in oil-feed plate and goes out between oiled-plate method.
Further, described motor is brushless electric machine.
Further, described pump head adopts novel PPS plastics, comprises following component, PPS plastics 50wt% ~ 70wt%, oiling agent 30wt% ~ 40wt%, additive 5wt% ~ 10wt%.
Further, described oiling agent is by carbon material, nano-ceramic powder, French chalk, Furtulon plastics, one or more form.
Further, by titanium dioxide, glass, one or more form other additives described.
Compared with prior art, the invention has the advantages that: first motor housing and controller, staor winding are packaged as a whole, decrease and the number of components directly contacted with fuel oil in fuel pump and area, decrease wearing and tearing, secondly be also the most important, the present invention is by after improvement PPS plastics, and the operating life of pump head can reach more than 4000 hours or 100,000 kilometers, considerably increase the working life of fuel pump, its concrete composition function is as follows:
Carbon material: increase hardness and wear resistance, special its self lubricity of increase;
Nano-ceramic powder: to gain in strength, wear resistance, improves self-lubricating property;
Titanium dioxide: improved strength;
French chalk: gain in strength, improves self-lubricating property;
Furtulon plastics: increase not viscosity and selflubricating degree;
Glass: gain in strength;
PPS plastic components science after improvement, successful, in methyl alcohol working environment, the life-span is long, corrosion resistance and good, and self-lubricating property is good, and during work, noise little (being less than 50 decibels).
