Abstract
The utility model discloses an impeller with a new structure for an automobile fuel pump, which comprises an impeller body, wherein a mounting hole for mounting a rotor is formed in the center of the impeller body, a plurality of blades are uniformly arranged on the outer circumference of the impeller body, the outer circles of the blades are connected through an outer ring, a circle of balance holes are formed in the impeller body around the mounting hole, an injection molding opening is formed in the impeller body, a circle of exhaust holes are formed in the impeller body, and the exhaust holes are located on the outer side of the balance holes. After the exhaust hole is arranged, the exhaust hole can dissolve bubbles generated when oil is fed and discharged, so that the noise generated when the impeller works is reduced; meanwhile, the exhaust holes reduce the weight of the impeller, so that the rotational inertia of the impeller is reduced, and the rotational stability of the impeller is improved.
Description
Technical Field
The utility model belongs to the technical field of fuel pumps of automobiles and motorcycles, and particularly relates to an impeller with a novel structure for an automobile fuel pump.
Background
In the prior art, the oil inlet cover is attached to the impeller, and the working surface of the oil inlet cover attached to the impeller is a whole plane.
SUMMERY OF THE UTILITY MODEL
The utility model provides an impeller with a new structure for an automobile fuel pump, which reduces the rotational inertia of the impeller during rotation so as to reduce the noise generated during the operation of the impeller.
Therefore, the technical scheme adopted by the utility model is as follows: the utility model provides an automobile fuel pump new construction impeller, includes the impeller body, the impeller body center is provided with the mounting hole that is used for the rotor installation, evenly be provided with a plurality of blades on the outer circumference of impeller body, the excircle of blade passes through the outer loop and connects, be provided with round balancing hole around the mounting hole on the impeller body, be provided with the mouth of moulding plastics on the impeller body, be provided with the round exhaust hole on the impeller body, just the exhaust hole is located the balancing hole outside.
Preferably, the number of the balance holes is three along the circle center of the mounting hole.
Preferably, eight exhaust holes are uniformly formed in the circle center of the mounting hole.
Further preferably, the injection molding port is a counter bore, and the injection molding port is arranged between the two balance holes.
The utility model has the beneficial effects that: after the exhaust hole is arranged, the exhaust hole can dissolve bubbles generated when oil is fed and discharged, so that the noise generated when the impeller works is reduced; meanwhile, the exhaust holes reduce the weight of the impeller, so that the rotational inertia of the impeller is reduced, and the rotational stability of the impeller is improved.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The utility model will be further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in figure 1, the impeller with the new structure of the automobile fuel pump mainly comprises an impeller body 1, blades 3 and an outer ring 4. Wherein the blades 3 are provided on the outer circumference of the impeller body 1, and the outer ring 4 is provided at the other end of the blades 3 and connects all the blades 3. In the present invention, the blades 3 are provided with 48 blades and uniformly distributed.
The center of the impeller body 1 is provided with a mounting hole 2 for mounting the rotor, and the mounting hole 2 is set to be a major arc hole in order to ensure that the impeller can rotate along with the rotor. In order to facilitate the balance of the impeller during starting, a balance hole 5 is arranged at the position of the impeller body 1 close to the mounting hole 2. Preferably, there are three balancing holes 5, evenly distributed along the circle of the mounting hole 2.
In order to facilitate the injection molding of the impeller, an injection molding port 6 is arranged on the impeller body 1, and the injection molding port 6 is a counter bore which is convenient for grinding the plane of the impeller.
In order to solve the bubbles generated during the oil inlet and outlet and prevent the bubbles from vibrating to generate noise, the impeller body 1 is provided with the exhaust hole 7, the exhaust hole 7 is positioned on the outer side 4 of the balance hole, and the exhaust hole 7 can reduce the weight of the impeller, so that the rotational inertia of the impeller is reduced, and the rotational stability of the impeller is improved. In the utility model, eight exhaust holes 7 are uniformly arranged along the circle center of the mounting hole 2.
Tests show that the impeller with the exhaust holes improves the overall efficiency of the pump core by 3-5%, reduces noise when the pump core works, and particularly reduces 20-25-order noise.
