Description
Technical field
The present invention relates to motor vehicle fuel pump, particularly a kind of life-span permanent, uncorruptible mixed power fuel oil pump.
Background technique
Fuel pump is the technical term of auto parts machinery industry.It is one of fundamental composition of electro jet car fuel injection system.Effect is transported in fuel supply line after fuel oil sucking-off from fuel tank, pressurization, and certain fuel pressure is set up in fuel pressure regulator cooperation.Reality use after can find, fuel pump in use between after long afterwards, the methyl alcohol that inside is passed through or different fuel can corrode the parts such as rotor, connecting line, whole fuel pump is caused to use, just need to carry out maintain and replace through after a while, working life is not long, bothers very much.The fuel oil that the disclosed fuel pump inside with selling is passed through on the market now all directly passes through from rotor, so we need long service life, and uncorruptible fuel pump.
Summary of the invention
For the problem that the solution actual life intermediate fuel oil pump easy burn into life-span is not grown, the object of this invention is to provide the mixed power fuel oil pump that a kind of long perfomance life, not easily burn into rotor and oil circuit are provided separately.
For achieving the above object, technological scheme of the present invention:
A kind of mixed power fuel oil pump, comprise frame, pump cover, pump head, inner housing, impeller, magnetic shoe, rotor, carbon brush, joint, oil pipe, cylindrical and the boring of described frame, frame two ends are separately installed with pump head and pump cover, pump cover is provided with step, pump head has recess, inner housing one end is socketed in the other end on step and is placed in recess, pump cover extends inlet opening, pump head extends oil pipe, between inner housing and frame, space forms oil circuit, inlet opening on oil circuit and pump cover, oil pipe on pump head is interconnected, inner housing inwall is provided with magnetic shoe, rotor is provided with in magnetic shoe, run through in rotor and have coupling shaft, coupling shaft one end is placed in the positioning hole of pump head, the other end is connected with the impeller in pump cover, coupling shaft two ends are socketed with seal ring, the carbon brush of two connection both positive and negative polarities is installed above the inherent rotor of pump head, carbon brush is connected to joint.
As preferably, mutually isolated between described inner housing and oil circuit.
As preferably, described joint connects power supply.
As preferably, described coupling shaft is processed with plane in impeller joint.
Advantage has: long perfomance life, not perishable, and rotor and oil circuit are provided separately.
