Description
Technical field
The utility model relates to a kind of electric fuel punp, relates in particular to a kind of automatic Regulation motorcycle pipeline electric fuel punp.
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, for this reason, my company has researched and developed and has produced the electric fuel punp that a kind of suitable motorcycle is used before this, but the pressure transient of this motor Vehicular electric fuel pump output fuel, size can not be regulated according to different automobile types.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of pressure stability is provided, the automatic Regulation motorcycle pipeline electric fuel punp of adjustable size.
The technological scheme that the utility model adopted is: automatic Regulation motorcycle pipeline electric fuel punp, comprise electric fuel punp, electric fuel punp comprises pump case, place the pump core that is provided with fuel oil suction port and exhaust port in the pump case and rotate the motor section that drives this pump core, fuel oil supply nozzle, suction port end at the pump core also is provided with the fuel oil input mouth, being provided with the pressure regulation assembly is connected with fuel oil supply nozzle, the pressure regulation assembly comprises pressure regulator valve, the pressure regulator valve support, pressure regulator valve places the pressure regulator valve support, the pressure regulator valve support is provided with the fuel filler passage and is communicated with fuel oil supply nozzle, and the fuel filler passage is communicated with fuel oil output mouth and pressure regulator valve fuel filler respectively again.
The utility model beneficial technical effects is: be connected with the fuel oil supply nozzle of electric fuel punp owing to be provided with the pressure regulation assembly, the fuel oil of electric fuel punp output is regulated through the pressure regulation assembly, when pressure during greater than setting pressure, unnecessary fuel oil flows out and pressure release through the pressure regulation assembly, thereby guarantees that delivery pressure is stable; When regulating the pressure release pressure of pressure regulation assembly, just can adjust the delivery pressure of electric fuel punp.
