Description
Technical Field
The utility model relates to an improvement invention in the field of auto-parts, in particular to an improvement invention of a double-injection-interface fuel pump.
Background
With the development of automobile technology and increasingly stringent emission standards, more and more functions of a fuel injection system are integrated into a fuel tank, and an oil pump is also used, for example, remote oil absorption (suitable for a rear-drive or four-drive vehicle type) and injection oil supply, at present, three-way or four-way connection is mostly adopted on an oil nozzle in the market.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, practical two and draw and penetrate interface fuel pump.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: this kind of two draw and penetrate interface fuel pump, including the pump case of tube-shape, its characterized in that: the improved pump comprises a pump shell and is characterized in that an upper pump cover is arranged at the upper end of the pump shell, a lower pump cover is arranged at the lower end of the pump shell, the upper pump cover and the lower pump cover are enclosed to form a pump cavity, an armature and an impeller are arranged in the pump cavity, the impeller is driven by the armature, an oil outlet is formed in the upper pump cover, an oil inlet is formed in the lower pump cover, a magnetic shoe is arranged on the inner wall of the pump shell and is in electromagnetic induction fit with the armature, a first injection interface is further arranged on the lower pump cover and is communicated with the pump cavity, and a second injection interface is further arranged.
The beneficial effects of the utility model are that two after the improvement draw and penetrate the interface fuel pump, integrated for three kinds of functions of engine fuel feeding, long-range oil absorption and drawing, can improve oil tank space utilization, reduce the later maintenance expense.
Drawings
The following describes the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a left side view of fig. 1 according to the present invention.
Fig. 3 is a right side view of fig. 1 according to the present invention.
Detailed Description
The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. The double-injection-interface fuel pump comprises a cylindrical pump shell 1, wherein an upper pump cover 2 is arranged at the upper end of the pump shell 1, a lower pump cover 3 is arranged at the lower end of the pump shell 1, the upper pump cover 2 and the lower pump cover 3 are enclosed to form a pump cavity, an armature 4 and an impeller 5 are arranged in the pump cavity, the impeller 5 is driven by the armature 4, an oil outlet 6 is arranged on the upper pump cover 2, an oil inlet 7 is arranged on the lower pump cover 3, a magnetic tile 8 is arranged on the inner wall of the pump shell 1, the magnetic tile 8 is in electromagnetic induction fit with the armature 4, a first injection interface 9 is further arranged on the lower pump cover 3, the first injection interface 9 is communicated with the pump cavity, a second injection interface 10 is further arranged on the upper pump cover.
The utility model discloses an operating principle, after the fuel pump circular telegram, armature 4 begins to rotate, drive impeller 5, the fuel is inhaled from lower pump cover 3's oil inlet 7, the first interface 9 of drawing of installation is discharged from lower pump cover 3 to part fuel, form one drive power, most fuel is divided into two parts after armature 4 reachs the pump head, a small part fuel draws interface 10 to discharge from the second of last pump cover 2, form another drive power, surplus fuel flows from the oil outlet of last pump cover 2. The first injection interface 9 and the second injection interface 10 can be connected with other parts to drive other functions.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
