Abstract
The utility model discloses a built-in electric fuel pump for a motorcycle, which comprises an impeller which takes the shape of a circular plate and is provided with a complete circle blade along an outer peripheral edge part. A motor part for rotating and driving the impeller comprises a pump cover with a suction inlet and a pump chamber and a pump base with a discharge port and a pump chamber; the impeller is contained in the pump cover and the pump base; fuel at a discharge port flows from the outside of a rotor to a fuel output nozzle; and the blade on the end surface of the impeller is arranged into an arc shape and consists of a spiral positive blade and a reverse blade which are arranged symmetrically. The utility model has the advantages that relatively larger flow capacity also can be output under the situations that the external dimension of the electric fuel pump is reduced and the current is smaller, thereby satisfying the demands of the motorcycle for the fuel.
Description
Technical field
The utility model relates to a kind of electric fuel punp, relates in particular to the built-in electric fuel punp of a kind of motorcycle.
Background technique
At present, the oil supply system of motorcycle comprises fuel tank and Carburetor etc., as everyone knows, Carburetor exists oil consumption and the low problem of emission standard, and automobile is just brought into use electric fuel punp a long time ago, but the volume and the electric current of the electric fuel punp that automobile is used are bigger, can not be directly used in motorcycle, research and develop and produce the electric fuel punp that a kind of suitable motorcycle uses and seem very necessary.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides a kind of volume and electric current less, can guarantee the built-in electric fuel punp of motorcycle of certain flow again.
The technological scheme that the utility model adopted is: the built-in electric fuel punp of motorcycle comprises the impeller that is discoideus and has whole circle blade along outer periphery portion; Rotation drives the motor section of this impeller, and described motor section comprises motor shaft, rotor, permanent magnet and tubular shell; Relative with micro-gap and when forming the slip surface of the described impeller of supporting with the bi-side of described impeller, form the pump chamber of the zonal and arc of extending along the outer periphery portion of described impeller at the outer circumferential side of described slip surface, and be provided with fuel suction port in an end of described zonal and arc, the pump case that is provided with the pump chamber exhaust port in the other end and forms, be that described pump case comprises pump cover that is provided with suction port and pump chamber and the pump seat that is provided with exhaust port and pump chamber, impeller is placed among pump cover and the pump seat, the fuel oil of exhaust port is exported mouth through the rotor outside to fuel, the shape of described blade on the impeller end face is set to arc, blade is made of symmetrically arranged positive blade and anti-blade, positive blade is identical by the helix angle size with anti-blade, the certain thickness spire that has that direction is opposite constitutes, spire comprises fuel oil lead-in surface and fuel oil derivation face, and fuel oil lead-in surface and fuel oil derivation face are helicoid.
The utility model beneficial technical effects is: because the shape of blade on the impeller end face is set to arc, blade is made of positive blade of symmetrically arranged spirality and anti-blade, guarantee under the boundary dimension of electric fuel punp is dwindled situation with less electric current, can also export relatively large flow, make it can satisfy the demand of motorcycle fuel oil.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, the 1st, be discoideus and have the impeller of whole circle blade 14 along outer periphery portion, the 2nd, relative with a side of impeller 1 and have a pump cover of slip surface of supporting impeller 1 with micro-gap, the 3rd, be relative with the another side of impeller 1 and have a pump seat of slip surface of supporting impeller 1 with micro-gap, the 4th, form the pump chamber of two zonal and arc of extending along the whole circle blade 14 of described impeller 1 at the outer circumferential side of the slip surface of pump cover 2 and pump seat 3,5 are arranged on the fuel suction port of pump cover 2 one sides, 6 are arranged on the fuel discharge outlet of pump seat 3 one sides, constitute pump case 7 by pump cover 2 that is provided with suction port 5 and pump chamber 4 and the pump seat 3 that is provided with exhaust port 6 and pump chamber 4, the 12nd, the motor section of rotation drives impeller 1, described motor section 12 comprises motor shaft 8, rotor 9, permanent magnet 10 and tubular shell 11, impeller 1 is entrenched on the motor shaft 8, tubular shell 11 is installed by permanent magnet 10 and setting-in pump case 7 and fuel output mouth 13, impeller 1 is placed among pump cover 2 and the pump seat 3, and the fuel oil of exhaust port is exported mouth 13 through the rotor outside to fuel.As shown in Figure 2, the shape of described blade 14 on the impeller end face is set to arc, as shown in Figure 3, blade 14 is made of symmetrically arranged positive blade 21 and anti-blade 22, positive blade 21 and anti-blade 22 are in the shape of the letter V in the shape with the cross section of impeller middle spindle line parallel, described positive blade 21 is identical by the helix angle size with anti-blade 22, the certain thickness spire that has that direction is opposite constitutes, spire comprises fuel oil lead-in surface 23 and fuel oil derivation face 24, the relative distance that the thickness of spire is derived face 24 by fuel oil lead-in surface 23 and fuel oil determines that it is helicoid that fuel oil lead-in surface 23 and fuel oil are derived face 24.Fuel oil lead-in surface 23 and fuel oil are derived face 24 and 26 are provided with 1 °～3 ° pattern draft from root 25 to the top, i.e. the thickness of spire attenuation gradually from the root to the top is more prone to the demoulding.
As further improvement, described pump cover 2 and pump seat 3 are made by cold extrusion shaped aluminum alloy, have the low advantage of environmental protection and reject rate.The internal surface of the outer surface of described rotor 9 and tubular shell 11 is provided with corrosion-resistant coating, and motor shaft 8 is made by stainless steel material, has the characteristics of corrosion resistance and good, can be used for the vehicle of Aalcohols fuel.
