Description
Technical Field
The utility model relates to a motorcycle fuel pump field, concretely relates to novel external motorcycle fuel pump assembly.
Background
In the past external motorcycle fuel pump assembly, two objective problems always exist to influence the performance index of the product:
1. because the fuel pump is an external use environment, the fuel pump is arranged outside the fuel tank, the temperature generated by the fuel pump during operation can be only dissipated in the air through the shell, and the heat dissipated by the air is very limited; and the shell is mostly black, the fuel pump assembly can directly contact sunlight, and the black fuel pump assembly is easy to absorb light and absorb heat, so that the overall working temperature of the external fuel pump is much higher than that of the internal fuel pump, and the service life of the overall fuel pump is greatly reduced.
2. Because be external reason, the pipeline sealing performance requirement to fuel pump assembly itself is higher, because even only very minute leakage can directly reveal externally, can cause the potential safety hazard, the sealing washer design of product can expose externally in the past, so the sealing washer has great area contact external environment, the sealing washer is ageing with higher speed, influence the leakproofness, and the whole plane and the shell in close contact with that the sealing washer all adopted the sealing washer in the past seals, the large tracts of land contact leads to the whole less of sealing washer precompression volume, can direct influence sealing performance when there is the defect on complex shell surface with it.
SUMMERY OF THE UTILITY MODEL

provides a novel external motorcycle fuel pump assembly.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a novel external motorcycle fuel pump assembly, including the shell, install in the upper cover of shell opening part and install the sealing washer between upper cover and shell, be equipped with electronic injection fuel pump installation cavity in the shell, install electronic injection fuel pump in the electronic injection fuel pump installation cavity, the relative open-ended other end of shell is equipped with oil inlet and the oil-out with electronic injection fuel pump installation cavity intercommunication, covers on and is equipped with the fuel feeding passageway that is used for connecting the engine and supplies oil pipe way, its characterized in that: the utility model discloses a fuel injection pump, including shell, electricity spout fuel pump installation cavity, pressure regulator, upper cover, many strengthening ribs that electricity spout fuel pump installation cavity is equipped with along the annular distribution of inner wall, electricity spout the fuel pump install in electricity spout fuel pump installation cavity and closely laminate with the strengthening rib, form the oil storage chamber between each strengthening rib, the shell is equipped with the pressure regulator installation cavity with electricity spout fuel pump installation cavity intercommunication in electricity spout fuel pump installation cavity one side, install pressure regulator in the pressure regulator installation cavity, the upper cover is equipped with the pressure release passageway that one end communicates pressure regulator installation cavity other end.
By adopting the technical scheme, the utility model discloses a theory of operation does, fuel gets into in the electronic fuel pump installation cavity through the oil inlet of shell, a part is carried to the engine through the fuel feeding passageway that covers after the fuel is sprayed through the electronic fuel pump pressure boost, the engine consumes during remaining fuel gets into the pressure regulator through the pressure release passageway after some fuel, the pressure regulator adjusts the pressure stability in the fuel feeding passageway through releasing fuel, fuel after releasing through the pressure regulator flows into the electronic fuel pump installation cavity from the pressure regulator installation cavity and is full of the oil storage cavity in the middle of shell and the electronic fuel pump, fuel drives the electric fuel pump surface heat and returns in the oil tank of being connected with the oil return pipe through the oil return pipe when passing through the oil storage cavity, because the mounted position of oil tank is higher than the fuel pump assembly, so the oil storage cavity remains the full oil state all the time, the fuel of during operation can the circulation take away the produced heat of electronic fuel pump work, effectively reduce the operating temperature of the fuel pump, thereby prolonging the service life of the fuel pump.
The novel external motorcycle fuel pump assembly can be further set as follows: the reinforcing rib is far away from the one end of shell open-ended and extends to electricity and spout the inside formation of fuel pump installation cavity and support the end, electricity spouts fuel pump one end and supports the end and offset.
By adopting the technical scheme, the reinforcing rib is tightly attached to the housing of the electronic injection fuel pump, the electronic injection fuel pump is always radially clamped and fixed, the supporting end at the bottom provides axial support for the electronic injection fuel pump, and the electronic injection fuel pump can also normally and stably work in a state that the whole vehicle jolts under a working condition.
The novel external motorcycle fuel pump assembly can be further set as follows: the electric injection fuel pump mounting cavity is provided with a sealing ring mounting cavity towards one end of the opening, the sealing ring is mounted in the sealing ring mounting cavity, and the edge of the upper cover towards one end of the shell is provided with protrusions connected end to end.
By adopting the technical scheme, the sealing ring is arranged in the sealing ring mounting cavity, the bulge is designed on the edge of the upper cover, the sealing ring mounting cavity formed between the shell and the upper cover after the sealing ring is effectively protected after the shell is assembled can be matched with the shell, the contact between the sealing ring and the external environment is reduced, and the anti-aging performance of the sealing ring in the using process is improved.
The novel external motorcycle fuel pump assembly can be further set as follows: and a sealing ball rib is arranged on the sealing ring.
By adopting the technical scheme, the sealing ring is provided with the sealing ball rib used for sealing between the upper cover and the shell, under the same assembly condition, the prepressing amount of the sealing ball rib is larger, the sealing surface of the upper cover and the shell can be more effectively attached, effective sealing is realized, and fuel leakage is prevented.
The utility model has the advantages that: the design of the oil storage cavity solves the heat dissipation problem of the external fuel pump assembly, the service life of the external fuel pump assembly is prolonged, and the built-in sealing ring improves the sealing performance between the upper cover and the shell.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
