Abstract
The utility model discloses an electric drive fuel-injection pump used by an automobile engine, comprising a fuel inlet end cover (2), an impeller (3), an impeller shell (4), a shell (5), a magnetic shoe (6), a rotor (7), a commutator (8), a carbon brush (9), a fuel outlet end cover (10) and a non-return valve (13), wherein, the commutator (8) is an end face commutator, and the carbon brush (9) is arranged inside the fuel inlet end cover (10) and is in touch with the end face of the end face commutator (8). Both ends of a rotor shaft of the utility model are sealed by twice fractional step positioning, and the utility model has the advantages of good concentricity, small vibration, low noise, low current, and prolonging the service life of products. The utility model is particularly suitable for automobile engines like BUICK series and MODERN series and so on.
Description
One, technical field
The utility model relates to the electric fuel punp that a kind of motor car engine is used.
Two, background technique
At present, the motor car engine electric fuel punp that is applied to series such as Toyota, Honda is made of component such as oil-feed end cap, impeller, impeller housing, casing, magnetic shoe, rotor (containing rotor shaft, iron core), armature winding, commutator, carbon brush, fuel-displaced end cap, one-way valves, wherein commutator is cylinder type commutator (being that its commutator segment body parallels with the commutator spin axis), carbon brush is contained on the inner side end of fuel-displaced end cap, contacts with the bi-side (being commutator segment) of commutator.The rotor shaft of the fuel pump of this type is contained in the oil-feed end cap, oil outlet end covers to sealing installation simultaneously, and its concentricity is poor, and vibration is big, noise is high, electric current is high, has influenced the working life of product.
Three, model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and provides a kind of rotor shaft concentricity good electric fuel punp.
The purpose of this utility model realizes by following technical solution: a kind of electric fuel punp, comprise oil-feed end cap, impeller, impeller housing, casing, magnetic shoe, rotor, commutator, carbon brush, fuel-displaced end cap, one-way valve, described commutator is an end commutator, and described carbon brush is contained in the fuel-displaced end cap and contacts with the end face of end commutator.
After adopting the utility model structure, its rotor shaft can be installed in oil outlet end earlier by positioning fixture and cover and seal, and the other end of rotor shaft is installed in accordingly on oil-feed end cap and the impeller housing and seals then.Therefore, the utility model compared with prior art, the two ends of rotor shaft are that seal twice substep location, its concentricity is good, vibrate little, noise is low, electric current is low, has prolonged the working life of product.Be specially adapted to the motor car engine of series such as Buick, modern times.
Four, description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model electric fuel punp.
Five, embodiment
With reference to Fig. 1 as can be known, the utility model electric fuel punp, comprise oil-feed end cap 2, impeller 3, impeller housing 4, casing 5, magnetic shoe 6, rotor 7, oil-impregnated bearing 12, commutator 8, carbon brush 9 and brush holder spring 11, fuel-displaced end cap 10, one-way valve 13 and check valve spring 14, described commutator 8 (is that its commutator segment body and commutator spin axis are perpendicular for end commutator, claim flat commutator again), and described carbon brush 9 (and brush holder spring 11) is contained in the fuel-displaced end cap 10 and with the end face (being commutator segment) of end commutator 8 and contacts.
Working procedure of the present utility model is: the fuel that motor is used is entered by the oil-feed end cap, makes fuel be pressed into casing inside through impeller, impeller housing through the rotation of rotor shaft impeller, is flowed out through one-way valve by fuel-displaced end cap again.
Claims (1)
