Abstract
The utility model discloses a pipeline-shaped fuel delivery pump, which comprises an external shell body and an end cover connected with the shell body. Two ends of the end cover are provided with a fuel inlet and a fuel outlet. A blade pump driven by a motor is arranged in the external shell body. The blade pump comprises an internal shell body, and a blade-pump inlet and a blade-pump outlet are respectively arranged on two ends of the external shell body. The blade-pump inlet and the blade-pump outlet are respectively connected with the fuel inlet and the fuel outlet. Pump components and a pump cover which form a pump cavity are arranged in the internal shell body. A pump rotor is arranged in the pump cavity, and blades are arranged in the blade groove of the pump rotor. The pump rotor is fixed and connected with the revolving shaft of the motor. Since the inside of the pipeline-type fuel delivery pump adopts the blade-pump structure which is mature and simple and which has the advantages of high-temperature resistance and corrosion resistance features, and the utility model has the advantages of good reliability and long service life.
Description
Technical field
The utility model relates to a kind of fuel transfer pump, relates in particular to a kind of electric fuel pump.
Background technique
At present, fuel transfer pump mainly contains two kinds of structures by mounting type, and a kind of is the immersion fuel transfer pump, and another kind is an electric fuel pump, and the utility model belongs to a kind of structure in back.The electric fuel pump of prior art comprises frame and the end cap of fixedlying connected with frame, be provided with oil inlet hole and oil outlet at the two ends of end cap, its internal structure is the electronic vibration plunger-type fuel pump, complex structure, high temperature resistant and the oil resistance of the electronic parts and components of this pump is relatively poor, has poor reliability, short shortcoming of life-span.
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 simple in structure, good reliability, long electric fuel pump of life-span are provided.
The technological scheme that the utility model adopted is: a kind of electric fuel pump, comprise frame and the end cap of fixedlying connected with frame, be provided with oil inlet hole and oil outlet at the two ends of end cap, be provided with in the described frame by motor-driven vane pump, described vane pump comprises that two ends are respectively equipped with the inner housing of vane pump import and vane pump outlet, vane pump import and vane pump outlet are communicated with oil inlet hole and oil outlet respectively, in inner housing, be provided with the pump assembly and the pump cover that constitute pump chamber, in pump chamber, be provided with pump rotor, be provided with blade in the blade groove of pump rotor, pump rotor is fixedlyed connected with the rotating shaft of motor.
The utility model beneficial technical effects is: because motor-driven vane pump structure is adopted in the inside of electric fuel pump, vane pump structure maturation, simple, have high temperature resistant and corrosion resistant characteristics, thereby, the utlity model has good reliability, long advantage of life-span.
