Abstract

The embodiment of the utility model discloses an impeller, which comprises an impeller disk, wherein the impeller disk is also provided with a plurality of through holes. As shown by the technical scheme, the novel impeller has the advantage that the added holes can convect the liquid (gasoline) at both ends of the impeller, which can help to dissipate the heat of the impeller. In addition, the holes can reduce plane friction, reduce the loss of useless work of a motor and ensure that the impeller cannot be deformed during rotation; granular powder and impurities which cannot be filtered by a filter net can exist in an oil tank, the pump body can be easily jammed after the granular powder and the impurities are sucked into the pump body as an oil pump pumps oil, and after grooves are added, the impurities can fall into the grooves, so that the impeller cannot be jammed.

Description

A kind of impeller
Technical field
The utility model relates to impeller and makes the field, more particularly, relates to the impeller in the electric-spraying fuel pump.
Background technique
Impeller (impeller) claim active wheel again, and only element to the air-flow work done also is epitrochanterian main parts in the centrifugal compressor.Generally be made up of parts such as blade 1 and wheel discs 2, as shown in Figure 1, gas is made high speed rotating with impeller under the effect of impeller blade, and gas is subjected to the effect of rotary centrifugal force, and the diffusion in impeller flows, and the pressure after making it by impeller is improved.Requirement to impeller is: (1) can provide bigger energy head; (2) it is little that gas stream is crossed the loss of impeller, and promptly gas stream wants high through the efficient of impeller; Each parameter was suitable when (3) gas stream went out impeller, and later the flow losses during the face fixed element are less to make gas stream; (4) impeller type can make steady working condition district and efficient district wider range of level or complete machine performance curve.Often be divided into enclosed, semi-open type and unshrouded impeller.When oil pump pump oil, impeller all will run up and produce the difficult heat radiation of a large amount of heats, influences the working life of oil pump.
The model utility content
In view of this, the utility model provides a kind of impeller, changes its radiating effect when impeller rotates to be implemented in.
For achieving the above object, the utility model provides following technological scheme:
A kind of impeller comprises: wheel disc wherein, also is provided with a plurality of through holes on the described wheel disc.
Preferably, in above-mentioned impeller, described through hole becomes regular polygon to distribute.
Preferably, in above-mentioned impeller, the number of described through hole is 5.
Preferably, in above-mentioned impeller, also be provided with groove at described lead to the hole site.
From technique scheme as can be seen, the benefit of new impeller increases liquid (gasoline) convection current that a plurality of holes make the impeller two ends in the utility model, helps the impeller heat radiation.In addition, the friction on plane is reduced in a plurality of holes, reduces the loss of motor idle work, helps impeller and can not produce distortion when rotated; Have granular powder and impurity that strainer filtering does not fall in the fuel tank, in oil pump when oil pumping, suck behind the pump housing stuck easily, increased groove after, impurity drops in the groove, impeller just can not be stuck.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of impeller in the prior art;
The blade wheel structure schematic representation that Fig. 2 provides for the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of impeller, changes its radiating effect when impeller rotates to be implemented in.
As shown in Figure 2, a kind of impeller comprises blade 1 and wheel disc 2, is provided with a plurality of through holes 21 on wheel disc 2, can help impeller to dispel the heat when rotated, and a plurality of through holes 21 are regular polygon and are distributed on the wheel disc 2, and the geometrical center of regular polygon is the center of circle of wheel disc 2.
In addition, be made as groove 22 at lead to the hole site, strainer filtering does not fall in the fuel tank granular powder and impurity, increased groove after, impurity drops in the groove, impeller just can not be stuck.
Through hole 21 and groove 22 are designed to five in the utility model, are regular pentagon and are distributed on the wheel disc.
Adopt the impeller of said structure, increase liquid (gasoline) convection current that a plurality of holes make the impeller two ends, help the impeller heat radiation.In addition, the friction on plane is reduced in a plurality of holes, reduces the loss of motor idle work, helps impeller and can not produce distortion when rotated; Have granular powder and impurity that strainer filtering does not fall in the fuel tank, in oil pump when oil pumping, suck behind the pump housing stuck easily, increased groove after, impurity drops in the groove, impeller just can not be stuck.
The invention also discloses the pump with above-mentioned impeller, this pump has the advantage of above-mentioned impeller, need not to give unnecessary details at this.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.

Claims (4)

1. impeller comprises: wheel disc, it is characterized in that, and wherein, also be provided with a plurality of through holes on the described wheel disc.
2. impeller according to claim 1 is characterized in that, described through hole becomes regular polygon to distribute, and the geometrical center of regular polygon is the center of circle of described wheel disc.
