Abstract
The invention discloses a pressure impeller with non-uniformly distributed blades. The pressure impeller comprises a pressure impeller body, a plurality of large blades and a plurality of small blades; the plurality of large blades and the plurality of small blades are arranged on the pressure impeller body; the plurality of large blades and the plurality of small blades are uniformly distributed along the circumferential direction; the large blades and the small blades are arranged separately; the included angles between every small blade and the two adjacent large blades in the circumferential direction are not equal. Accordingly, the structure is simple and reasonable, the gas flow state when the pressure impeller runs at the surge operating point can be improved, and the purpose of surge inhibition can be achieved.
Description
Technical field
The present invention relates to turbo-charger technical field, particularly relate to a kind of pressure impeller of unequal distribution blade.
Background technique
Turbosupercharger is a kind of machinery being widely adopted on motor, and it reaches by air is compressed the object that increases air input of engine by air, thereby improves the burning of motor, improves the thermal efficiency and increases engine output moment of torsion.The pressure impeller of turbosupercharger directly acts on the vital part that air compresses just.
Due to the complexity of engine working conditions, also there are some problems in turbocharger applications aspect at present, and surge is one of them Typical Representative.During turbosupercharger generation surge, the air stream of blower outlet end there will be strong vibration, causes the vibration that blade is strong, and the very large noise of generation, can there is obvious decline in the pressure of outlet, and follow very large fluctuation, even can cause the damage of component.
The reason that surge occurs is because charge flow rate is when too small, presses and airflow breakaway can occur near impeller surface and flow backwards to cause.
Typical turbosupercharger, it presses impeller generally some identical blades or one group of large blade and one group of small leaf, to consist of, and as shown in Figure 2 and Figure 3, common ground is that adjacent two blades are identical at the angle of circumferencial direction.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of pressure impeller of unequal distribution blade, simple and reasonable, can improve the flowing gas state while operating in surging condition point, reaches the object that suppresses surge.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: the pressure impeller that a kind of unequal distribution blade is provided, comprise: press impeller matrix, be arranged on the multiple large blade on described pressure impeller matrix and be arranged on the multiple small leaf on described pressure impeller matrix, described multiple large blade is along the circumferential direction uniformly distributed, described multiple small leaf is along the circumferential direction uniformly distributed, described large blade and small leaf interval arrange, and between described small leaf and adjacent two large blades, angle is in a circumferential direction unequal.
In a preferred embodiment of the present invention, between described small leaf and adjacent two large blades, angle is in a circumferential direction respectively 20 ° and 40 °.
In a preferred embodiment of the present invention, described large blade and small leaf are all to adopt aluminum alloy to make.
The invention has the beneficial effects as follows: the pressure impeller of a kind of unequal distribution blade of the present invention, simple and reasonable, can improve the flowing gas state while operating in surging condition point, reach the object that suppresses surge.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of pressure impeller one preferred embodiment of a kind of unequal distribution blade of the present invention;
Fig. 2 is a kind of structural representation of existing pressure impeller;
Fig. 3 is the another kind of structural representation of existing pressure impeller.
In accompanying drawing, the mark of each parts is as follows: 1, small leaf, 2, large blade.
Embodiment
To the technological scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of pressure impeller of unequal distribution blade, comprise: press impeller matrix, be arranged on the multiple large blade 2 on described pressure impeller matrix and be arranged on the multiple small leaf 1 on described pressure impeller matrix, described multiple large blade 2 is along the circumferential direction uniformly distributed, described multiple small leaf 1 is along the circumferential direction uniformly distributed, described large blade 2 and small leaf 1 interval arrange, between described small leaf 1 and adjacent two large blades 2, angle is in a circumferential direction unequal, as shown in Figure 1, angle A is not equal to angle B, the air-flow path width forming between small leaf 1 and adjacent two large blades 2 is like this different, the flow difference of passing through while causing operation, thereby improve the flowing gas state while operating in surging condition point, reach the object that suppresses surge.
Preferably, between described small leaf 1 and adjacent two large blades 2, angle is in a circumferential direction respectively angle B20 ° and angle A40 °.
Described large blade 2 and small leaf 1 are all to adopt aluminum alloy to make, and have advantages of that intensity is high, quality is light, long service life.
The pressure impeller of a kind of unequal distribution blade of the present invention, simple and reasonable, can improve the flowing gas state while operating in surging condition point, reach the object that suppresses surge.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
