Abstract
The utility model relates to a pump head of a fuel pump. The pump head comprises an oil inlet plate, an outer ring is arranged under the oil inlet plate, an outer rotor is fixed inside the outer ring, and an inner rotor is meshed inside the outer rotor. The inner rotor is driven by an impeller connected with a motor. The pump head is reasonable in design, the transmission efficiency between the rotors is high, and the rotors are exquisite in design, appropriate in size and suitable for being popularized in a large-scale mode.
Description
Technical field
The utility model relates to fuel pump, is specifically related to fuel pump pump head.
Background technique
Methanol fuel pump is the critical component in automobile electronic fuel oil jet system, except providing automobile power required fuel oil, also plays the effect of stablizing EFI system pressure, so the efficient and long lifetime of methanol fuel pump is automobile key point working properly.In addition along with the minimizing of world petroleum resource, and non-renewable, the use of novel energy, particularly recyclable fuel---the use of methyl alcohol, brought a new revolution to vehicle fuel power, but the design of current fuel pump pump head is unreasonable, volume is large, efficiency is low, is not suitable for mass production.
Model utility content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of fuel pump pump head reasonable in design.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of fuel pump pump head, comprise oil-feed plate, and be provided with outer ring below described oil-feed plate, this the inside, outer ring is fixed with external rotor, external rotor the inside is engaged with internal rotor, and internal rotor drives by impeller, and impeller connects motor.
Further, described inner surface is provided with polygonal groove, and described external rotor outer surface is provided with and the corresponding chimb of this polygonal groove.
Further, described external rotor internal surface is provided with groove.
Compared with prior art, the utility model has the advantage of: the utility model is reasonable in design, the transmission efficiency between rotor is high, and rotor design is consummate, and size to fit, is applicable to large-scale promotion.
Accompanying drawing explanation
