Abstract
The utility model discloses an impeller for a fuel pump. The impeller comprises an impeller body which is in a circular plate shape integrally, wherein an annular blade groove is formed in the impeller body and is close to the periphery of the impeller body; through pressure balancing lubrication holes are formed in the end surface of the impeller body on the inner side of the blade groove; cambered oil storage grooves are formed in two end surfaces of each pressure balancing lubrication hole; a plurality of blades are transversely connected between an outer ring side and an inner ring side in the blade groove; and one sides, which are along the oil inlet direction of the blade groove, of the blades and one sides, which are along the oil outlet direction of the blade groove, of the blades tilt to each other and are arranged symmetrically. By adopting the structure, an applicant arranges a plurality of blades in the blade groove, and moreover, the distance between adjacent blades is unequal, so that the design accords with a hydromechanical principle; and when the impeller rotates at high speed, fuel passes through the blades, so that noise is reduced to a great extent.
Description
Technical field
The utility model relates to a kind of electric fuel punp, especially relates to a kind of fuel pump impeller.
Background technique
Electric fuel punp is installed on the automotive oil tank, has played the function of supplying with vehicle fuel in the vehicle fuel supply system.During the electric fuel oil pump work, fuel oil enters in the end bucket under the running of pump core drives, and the filtration of process filter screen enters pump core filler opening, arrives automotive fuel oil system by pump core oil outlet through oil outlet tube again.After the motor car engine utilization, the part fuel oil arrives the pressure valve of electric fuel punp, guarantee that by pressure valve automotive fuel oil system is in the high pressure conditions of work all the time, when oil-fired system pressure reaches pressure valve pressure release state, fuel oil releases from the pressure valve oil outlet, and bucket is interior for the pump core on earth through the lead-jetting device injection on the return tube.
The fuel pump that contains annular impeller, cost of production is relatively low, sane and efficient, and is very extensive in the high pressure low-flow applications especially.But existing fuel pump impeller is unreasonable owing to designing, thereby can produce harsh noise when High Rotation Speed.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of novelty simple in structure, can reduce the fuel pump impeller of noise.
The technical solution of the utility model is as follows: a kind of fuel pump impeller, comprise that integral body is discoideus impeller body, on this impeller body, be provided with the blade groove of an annular near the periphery place, be provided with the pressure balance lubrication hole of perforation at the described impeller body end face of this blade groove inboard, the both ends of the surface of described pressure balance lubrication hole offer the oil storage tank of arc, its main points are: be horizontally connected with some blades between the side, outer ring in described blade groove and the inner ring side, described blade mutually tilts and is symmetrical arranged along a side of a side of described blade groove oil-feed direction and fuel-displaced direction.Adopt above structure, the claimant will arrange some blades in blade groove, and the distance between the adjacent blades do not wait, and more meet hydromechanical principle, and during the impeller High Rotation Speed, fuel passes between the blade, has reduced largely noise.
As preferably: for the design that makes impeller more reasonable, the noise that produces during simultaneously with the impeller High Rotation Speed drops in the more rational scope, the number of described blade is 46, take the line at the 1st blade left side and described impeller body center as reference line, each described blade right side and the line at described impeller body center and the angle of reference line are followed successively by: 8.4 °, 15.5 °, 23.8 °, 30.3 °, 38.1 °, 45.0 °, 52.0 °, 60.0 °, 69.2 °, 77.0 °, 86.0 °, 95.6 °, 102.2 °, 110.6 °,
119.0°、125.6°、132.2°、139.1°、145.6°、152.5°、159.0°、
167.3°、175.9°、184.2°、190.8°、197.4°、204.6°、211.8°、
221.0°、228.6°、235.3°、242.5°、251.5°、259.0°、266.6°、
