Abstract
The utility model discloses a methanol fuel pump for an automobile, which comprises a shell, a motor and an impeller, wherein the motor is arranged in the shell; the impeller is driven by the motor which is an inner rotor brushless motor; a controller used for controlling the motor to operate is arranged on the back part of a motor casing of the motor, and the controller and the motor casing are packaged into a whole together with a stator winding in the motor casing; and fuel guiding openings used for fuel to flow through are formed between the motor casing and the shell. Because the motor casing, the controller and the stator winding are packaged into a whole, the quantity and the area of components which directly come into contact with the fuel in the fuel pump are reduced; and in addition, according to the characteristic that pressure liquid flows to the direction of high flow, the three fuel guiding openings are formed outside the motor casing, so that the pumped methanol fuel flows to fuel outlets through the three fuel guiding openings, methanol entering the motor is effectively reduced, the etching effect of the methanol on the fuel pump can be reduced to the maximum, and the service life of the fuel pump is prolonged.
Description
Technical field
The utility model belongs to the fuel pump technical field, is specifically related to a kind of vehicle fuel pump structure take methyl alcohol as fuel.
Background technique
Automobile fuel pump is the critical component in the automobile electronic fuel oil jet system, except providing automobile power required fuel oil, also plays the effect of stablizing the EFI system pressure, so the efficient and long lifetime of automobile fuel pump is automobile key point working properly.In addition along with the minimizing of world petroleum resource, and non-renewable, the use of the use of novel energy, particularly renewable fuel oil-methyl alcohol has brought a new revolution for vehicle fuel power.But methyl alcohol has extremely strong corrosivity to metallic material, makes traditional gasoline automobile fuel pump obtain great challenge, and existing fuel pump must to anti-methyl alcohol corrosion, improve the future development in working life.
Summary of the invention
The purpose of this utility model is: for existing fuel pump in use, be exposed to the problem that the metal parts in the fuel oil is very easily corroded by new energy materials methyl alcohol, provide a kind of rational in infrastructure, material is durable, can resist the fuel pump for motor vehicle of methyl alcohol.
For realizing the purpose of the utility model, be achieved by the following technical solutions: a kind of automotive methanol fuel pump, include housing, be arranged in the housing motor and by motor-driven impeller, described motor is the inner-rotor brushless motor, the controller of control motor rotation is arranged on the motor housing rear portion of motor, and described controller is packaged as a whole together with the staor winding and the motor housing that are arranged in the motor housing, leaves the oil diverting port that flows through for fuel oil between motor housing and the housing.
As preferred version: described oil diverting port evenly is provided with three, and the sagittal plane area of each oil diverting port is 0.5cm
2-1.5cm
2The fuel oil that flows into from filler opening all flows to oil outlet from oil diverting port, has avoided fuel oil that motor internal is produced and has washed away.
As preferred version: the rotating shaft of described inner walls, motor housing, motor is coated with etch resistant material layer outward.After the parts that said structure has reduced as far as possible with fuel oil contacts, apply etch resistant material layer to prolong the whole service life of fuel pump at the parts that still are exposed in the fuel oil.
Compared with prior art, the beneficial effects of the utility model are: because motor housing and controller, staor winding are packaged as a whole, reduced with fuel pump in the number of components and the area that directly contact with fuel oil, the characteristic that flows to large direction of the traffic according to the pressured fluid flow direction in addition, outside motor housing, offer 3 oil diverting ports, make the methanol fuel oil that pumps up flow to oil outlet by this three places oil diverting port, effectively alleviating methyl alcohol enters in the motor, can lower to greatest extent methyl alcohol to the erosion of fuel pump, improve the working life of fuel pump.

Embodiment
The below makes a detailed explanation embodiment of the present utility model with reference to the accompanying drawings.
According to illustrated in figures 1 and 2, the described a kind of automotive methanol fuel pump of the present embodiment, include housing 2, be arranged in the housing 2 motor and by motor-driven impeller 10, described motor is the inner-rotor brushless motor, the controller 4 of control motor rotation is arranged on motor housing 3 rear portions of motor, described controller 4 uses corrosion-resistant plastic to be packaged as a whole together with the staor winding 7 that is arranged in the motor housing 3 with motor housing 3, leaves the oil diverting port 9 that flows through for fuel oil between motor housing 3 and the housing 2.
Described oil diverting port 9 evenly is provided with three, and the sagittal plane area of each oil diverting port 9 is 0.5cm
2-1.5cm
2The fuel oil that flows into from filler opening 1 all flows to oil outlet 5 from oil diverting port 9, has avoided fuel oil that motor internal is produced and has washed away.
The rotating shaft 8 outer etch resistant material layers that are coated with of described housing 2 inwalls, motor housing 3, motor.After the parts that said structure has reduced as far as possible with fuel oil contacts, apply etch resistant material layer to prolong the whole service life of fuel pump at the parts that still are exposed in the fuel oil.
It also is outward to encapsulate with resistant material that the wire of controller 4 contacts is connected to the circuit interface 6 on the housing 2, described wire, and circuit interface 6 inboards, wire and controller 4 are all isolated with fuel oil.
This fuel pump is owing to being packaged as a whole motor housing 3 and controller 4, staor winding 7, reduced with fuel pump in the number of components and the area that directly contact with fuel oil, the characteristic that flows to large direction of the traffic according to the pressured fluid flow direction in addition, outside motor housing 3, offer 3 oil diverting ports 9, make the methanol fuel oil that pumps up flow to oil outlet 5 by this three places oil diverting port 9, effectively alleviating methyl alcohol enters in the motor, can lower to greatest extent methyl alcohol to the erosion of fuel pump, improve the working life of fuel pump.
