Abstract
The utility model discloses a novel oil pump which comprises an oil pump body and an impeller which is eccentrically arranged in a cavity of the oil pump body. The impeller comprises an impeller body and a plurality of blades, the blades and the impeller body are formed integrally, the blades are circumferentially and evenly distributed on the impeller body, and the impeller is made of rubber materials. According to the novel oil pump, the impeller is made of the rubber materials, therefore the impeller has the good elasticity, meanwhile, due to the integral design, when the blades are compressed, the blades can adapt to the eccentrically-set size, gaps of the blades can be filled with the blades, air can be exhausted in a relatively-thorough mode, work performance of the oil pump can reach the relative ideal state, and due to the fact that the rubber blades can be freely deformed, the clamping phenomenon cannot happen.
Description
Technical field
The utility model relates to the design field of oil pump, is specifically related to Novel oil pump.
Background technique
The effect of oil pump is brought up to machine oil after certain pressure exactly, is sent to forcibly on the moving surface of the each part of motor, that is to say that oil pump is used for pumping machine oil, and is mainly used in the replacing of automobile engine oil and the transfer of other liquid.
The work of oil pump is exactly mainly to utilize impeller High Rotation Speed, air extrusion in impeller cavity is discharged, make cavity become vacuum state, and the liquid such as machine oil will enter in the cavity of oil pump by filler opening under the pressure of atmosphere, under the centrifugal force of oil pump impeller and the pressure-acting of blade, outwards flow out by oil outlet again.The liquid such as required machine oil are exactly so continuously from liquid pool, to be inhaled in oil pump cavity, then continuously spill out from oil outlet again, are finally sent on the moving surface of the each part of motor.
Its impeller of existing oil pump and blade are independently, be that impeller is provided with fluting, blade is placed in the fluting of impeller, in the time of vane rotary, can be with moving vane to rotate together, when blade rotary is to impeller distance of center circle from the nearest position of cavity inner wall, blade is subject to the squeezing action of cavity wall, blade can return in fluting gradually, and when blade rotary is during to impeller distance of center circle from position farthest of cavity inner wall, blade can be due to the effect of centrifugal force, from fluting, stretch out gradually, thus the function that realizes impeller pressurized air and carry transfer wet goods liquid.
But, the material of the individual vanes in existing oil pump is generally metal or plastics, because its hardness is harder, therefore can not free deformation, can not well adapt to the dimensional changes requirement of cavity, so it is also just higher to the requirement of its validity to add man-hour, and nowadays these hard blades are often difficult to reach needed precision, thereby the place that will cause blade to contact with cavity is gapped, and then make air row unclean, the whole machine oil pump performance of final impact, also can there is stuck phenomenon because the frictional force between blade and cavity is greater than the torsion of motor in the time marquis who even has, simultaneously, this mode that connects blade and impeller by notching construction, after Reusability, also there will be turnover fault.
Model utility content
Technical problem to be solved in the utility model is to solve when oil pump is used, easily break down and cannot fully discharge the problem of air.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is to provide a kind of Novel oil pump, comprise oil pump body and be eccentrically set on the impeller in described oil pump body cavity, described impeller comprise wheel body and with integrated several blades of described wheel body, described in several, blade circumference uniform distribution is arranged on described wheel body, and described impeller adopts quality of rubber materials.
In such scheme, described blade quantity is 12.
In such scheme, the end of described blade is spherical.
The utility model, the new oil oil pump adopting, its impeller adopts rubber material to be made, and therefore has good elastic force, simultaneously owing to being the design of impeller blade integral type, like this in the time that blade is compressed marquis can do by myself adapt to eccentric arrange size, and oneself plug the gap, so air is cleaner with regard to what arrange, the service behaviour of oil pump also just can reach more satisfactory state, and because rubber tree leaf can free deformation, so can there is not stuck phenomenon.
The utility model, this Novel oil pump of employing, its assembling is also more convenient, does not need to assemble separately blade again, as long as complete impeller installation step in the past, thereby has saved the expense of assembling, and makes its cost.In addition, do not need in use operator to do any back work, as long as oil inlet pipe and oil outlet tube are put into corresponding place, functional oil is sent in the oil pumping that then power-on can realize oil pump.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of Novel oil pump, comprise oil pump body 1 and be eccentrically set on the impeller 2 in oil pump body 1 cavity, impeller 2 comprise wheel body and with integrated several blades 3 of wheel body, several blade 3 circumference uniform distributions are arranged on wheel body, and impeller 2 adopts quality of rubber materials.
The end of blade 3 is spherical, can effectively weaken like this friction and the resistance in rotary course.In the present embodiment, blade 4 quantity are 12.
The utility model, the working principle of the Novel oil pump of employing is as follows:
Utilize rubber impeller and the setting of impeller eccentric, the distance of center circle that forwards impeller wheel body to when rubber tree leaf is from the nearest position of cavity inner wall, blade will compressedly be out of shape, because quality of rubber materials is softer, so blade can be realized Free Compression completely and can not damage, so just can and discharge outside cavity air extrusion, and the distance of center circle that turns over impeller wheel body when rubber tree leaf is from the nearest position of cavity inner wall, along with remaining in operation, blade can slowly return to again former extended configuration, simultaneously, the liquid such as required machine oil just can be carried and shift to oil outlet in space between blade and blade from filler opening, and the liquid such as machine oil is discharged cavity the most at last.So circulation, has completed oil pumping and has sent oily process.
The utility model, the new oil oil pump adopting, its impeller adopts rubber material to be made, and therefore has good elastic force, simultaneously owing to being integral type design, like this in the time that blade is compressed marquis can do by myself adapt to eccentric arrange size, and oneself plug the gap, so air is cleaner with regard to what arrange, the service behaviour of oil pump also just can reach more satisfactory state, and because rubber tree leaf can free deformation, so can there is not stuck phenomenon.
The utility model, this Novel oil pump of employing, its assembling is also more convenient, does not need to assemble separately blade again, as long as complete impeller installation step in the past, thereby has saved the expense of assembling, and makes its cost.In addition, do not need in use operator to do any back work, as long as oil inlet pipe and oil outlet tube are put into corresponding place, functional oil is sent in the oil pumping that then power-on can realize oil pump.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technological scheme, within all falling into protection domain of the present utility model.
