The electric fuel pump delivers sufficient fuel to the fuel injector and maintains a nominal pressure to ensure efficient injection of the fuel. The electric fuel pump is an extremely important component of an oil supply system and plays an important role in ensuring smoothness and stability of an oil way. Electric fuel pumps are typically constructed as an electromechanical assembly of a micro-pump connected to a micro-motor and encapsulated by a housing and auxiliary components for delivering fuel from the fuel tank to an engine in a fuel supply system for a gasoline or diesel engine (GB/T25984.1-2010).
When the motorcycle is running, fuel in the fuel tank shakes badly, so that fuel can not be sucked into a pump core of a fuel pump frequently, insufficient fuel is supplied, and the motorcycle is flamed out in the running process.
Disclosure of Invention
Aiming at the problems, the invention provides a motorcycle underneath fuel pump assembly, which solves the problem that the fuel is often supplied insufficiently when a motorcycle runs.
The technical scheme adopted by the invention is as follows:
the utility model provides a put fuel pump assembly under motorcycle, includes the fuel pump support to and filter screen subassembly, fuel pump core, air-vent valve, play oil pipe way and the glib talker of setting on the fuel pump support, the fuel pump support is equipped with the oil storage room at the oil inlet of fuel pump core, the pressure release mouth of air-vent valve links to each other with the oil storage room through returning oil pipe way.
Preferably, the filter screen assembly is L-shaped, wherein the longitudinal part is positioned outside the oil storage chamber, the transverse part is positioned in the oil storage chamber, and an oil outlet of the filter screen assembly is matched and fixed with an oil inlet of a pump core of the fuel pump in the oil storage chamber.
The longitudinal part of the filter screen assembly, which is positioned outside the oil storage chamber, is directly contacted with fuel oil in the oil tank, and the transverse part, which is positioned inside the oil storage chamber, is contacted with the fuel oil in the oil storage chamber, so that the pump core of the fuel pump can absorb oil from the oil tank and the oil storage chamber.
Preferably, the oil outlet pipeline passes through the oil storage chamber downwards and is connected with the oil outlet nozzle.
Preferably, the filter screen assembly is provided with an annular filter screen at the position of the oil outlet pipeline, and the oil outlet pipeline passes through the center of the annular filter screen downwards.
The annular filter screen is arranged, so that the oil outlet pipeline can conveniently pass through the annular filter screen, and the volume of the oil storage chamber is increased.
Preferably, the oil storage chamber comprises a ring of side wall fixed on the fuel pump bracket and a flange cover matched and fixed on the side wall.
The oil storage chamber adopts a structure that the side wall is combined with the flange cover, and has reasonable structure and convenient installation and fixation.
Preferably, the fuel pump bracket is provided with a fuel level sensor assembly.
The oil level sensor is used for monitoring the oil level in the oil tank in real time.
The fuel pump core is provided with the oil storage chamber below, and when the fuel pump core cannot absorb oil from the oil tank through the longitudinal part of the filter screen assembly in the running process of the motorcycle, the oil can still be absorbed from the oil storage chamber through the transverse part of the filter screen assembly, so that the oil supply is ensured, and the flameout of the motorcycle during running or rapid acceleration is avoided.

FIG. 2 is a schematic cross-sectional view of the present invention;
fig. 3 is a schematic view of a screen assembly.
Detailed Description
The invention is described in further detail below with reference to specific embodiments and with reference to the attached drawings.
Example 1
As shown in fig. 1-3, a motorcycle underneath fuel pump assembly comprises a fuel pump bracket 1, and a filter screen assembly 2, a fuel pump core 3, a pressure regulating valve 4, an oil outlet pipeline 5 and an oil outlet nozzle 6 which are arranged on the fuel pump bracket 1, wherein the fuel pump bracket 1 is provided with an oil storage chamber 7 at an oil inlet of the fuel pump core 3, and a pressure relief port of the pressure regulating valve 4 is connected with the oil storage chamber 7 through an oil return pipeline 8.
The filter screen assembly 2 is L-shaped, wherein the longitudinal part is positioned outside the oil storage chamber 7, the transverse part is positioned in the oil storage chamber 7, and the oil outlet of the filter screen assembly 2 is matched and fixed with the oil inlet of the pump core 3 of the fuel pump in the oil storage chamber 7.
The longitudinal part of the filter screen assembly 2 outside the oil storage chamber 7 is directly contacted with fuel in the oil tank, and the transverse part inside the oil storage chamber 7 is contacted with fuel in the oil storage chamber 7, so that the pump core 6 of the fuel pump can suck oil from the oil tank and the oil storage chamber 7.
The oil outlet pipeline 5 passes through the oil storage chamber 7 downwards and is connected with the oil outlet nozzle 6.
The sieve assembly 2 is provided with an annular sieve 9 at the position of the oil outlet pipeline 5, and the oil outlet pipeline 5 penetrates through the annular sieve 9 downwards from the center.
The annular filter screen 9 is arranged to facilitate the passing of the oil outlet pipeline 5, and simultaneously, the volume of the oil storage chamber 7 is increased.
The oil reservoir 7 comprises a ring of side walls 71 fixed to the fuel pump bracket 1 and a flange cover 72 fixed to the side walls 71 in a matching manner.
The fuel pump bracket 1 is provided with a fuel level sensor assembly 10.
The working principle of the invention is as follows:
when normally traveling, behind the filter screen subassembly 2 prefilter fuel, then inhale through fuel pump core 3, send fuel to play oil nozzle 6 and carry out the fuel feeding from play oil pipe way 5 behind air-vent valve 4, when if internal pressure reaches rated operating pressure, open air-vent valve 4 and carry out the pressure release, exhaust fuel gets back to in the oil storage chamber 7 through oil return pipe 8, when the fuel feeding, if the vehicle carries out the fuel of accelerating suddenly or vibrations in leading to the oil tank acutely rocks, the condition of not soaking in the fuel can appear in the longitudinal part of filter screen subassembly 2, at this moment, fuel pump core 3 can be through the horizontal part of filter screen subassembly 2 from the oil storage chamber 7 in the oil absorption, realize the fuel feeding, avoid flame-out.
