Background technology
Fuel pump is the component in automotive oil tank, now with people to discharge capacity demand, needs to improve fuel oil pump discharge, carry
High fuel oil pump discharge needs to improve the rotating speed of fuel pump, and the noise of fuel pump increases while improve rotating speed, affects user
Comfortable experience during use needs to be improved existing fuel pump to reduce noise, and in fuel pump Fuel injection system
The blade percussion in pump is increased with the promotion oil of flow, and then noise increases, the noise when flow is 85-95L/h reaches
To 48.3db, therefore, it is necessary to the runners to existing fuel pump to be improved.
Utility model content
The utility model provides a kind of electronic combustion to solve the problems, such as that noise is big after existing fuel pump increased flow capacity
Oil pump runner.
The utility model adopts the technical scheme that solve above-mentioned technical problem：
Including pump cover oil groove, impeller oilhole and lower pump body oil groove, and it is sequentially communicated and forms runner, the interlude of pump cover oil groove
Cross section is arc-shaped, and the oil outlet end of pump cover oil groove is connected with oil outlet, and the oil inlet end of pump cover oil groove is equipped with pit, pit
Bottom surface and the side of pit are arc transition, are connected by slope between pit and the interlude of pump cover oil groove, slope is arc
Shape and circular arc outwardly convex, pit and pump cover oil groove are respectively arc transition between slope；
The interlude cross section of lower pump body oil groove is arc-shaped, and the oil inlet end of lower pump body oil groove is connected with oil inlet, under
The oil outlet end of pump housing oil groove is identical as the oil inlet end structure of pump cover oil groove.
The utility model has the advantages that compared with prior art：
One, the utility model increases depth (setting pit) and the lower pump body oil groove oil inlet of fuel pump pump cover oil groove oil outlet end
The depth (setting pit) at end, and it is excessive by slope and circular arc, it is possible to reduce impact of the fuel oil to impeller, preferably control punching
The impeller beat brought is hit, friction of the impeller to lower pump body and pump cover is reduced, and then achievees the purpose that reduce noise.
Two, noise of the utility model when flow is 85-95L/h reaches 44.5db.
