Abstract
The utility model discloses an efficient guide ring used for a turbocharger. The efficient guide ring comprises a fixed ring which is fixedly connected to a turbine casing, and a plurality of blades are evenly distributed on the fixed ring, wherein the blades and the fixed ring form an integral structure. The blades are of a crescent-shaped structure, and the gap between each two adjacent blades forms a gas channel. The efficient guide ring used for the turbocharger not only is small in airflow loss and reduces the fuel oil consumption rate, but also is long in service life,and therefore the reliability of the whole machine is greatly improved.
Description
Technical field
The utility model relates to a kind of turbosupercharger, relates in particular to a kind of for the high-efficiency guide ring on the turbosupercharger.
Background technique
Motor is after the turbosupercharger that flow area variable (speed ring namely is housed) is installed, from the slow-speed of revolution under high-revolving different operating modes, can both realize the matched well of motor and pressurized machine, thereby torque characteristics, acceleration, the Economy of motor are significantly improved.The change of flow area is by the swing realization of blade.Little such as rotation speed change, the pressurized machine under the substantially invariable motor operation of a kind of rotating speed, its flow area also can be constant, and namely leaf position relative positioning ring maintains static.Such device, structure is just very simple.Traditional blade shape employing island is leaf, thin plate is leaf, wedge-like is symmetrical leaf, and is wherein especially general with the symmetrical leaf use of wedge-like.As shown in Figure 1, Fig. 1 is the structural representation of the wedge-like symmetrical blading on the traditional guide ring, and there is following shortcoming in this kind blade in concrete application process:
1) because outlet end (trailing edge) is thinner, approximate pointed, blade two sides air-flow crosses at this, and airspeed is uneven, and there is local eddy currents in the phase mutual interference, causes the bump loss, and the air-flow Trailing Edge Loss is large;
2) because entrance point (leading edge) is the blunt form curve, the adverse current area is larger, has strengthened the diffusion phenomenon, causes flow losses;
3) because the speed ring blade is worked in the gaseous environment that has particulate, high temperature for a long time, is greatly affected the working life of blade.Although guide ring parts integral body is intact, the blade tip place corrodes, distortion is comparatively serious, makes it premature failure.
The model utility content
It is a kind of for the high-efficiency guide ring on the turbosupercharger that the purpose of this utility model is to provide, and it has, and windage loss is little, boost pressure is stable and the characteristics of long service life, the problem that exists to solve the guide ring that is used for turbosupercharger in the prior art.
For reaching this purpose, the utility model by the following technical solutions:
A kind of for the high-efficiency guide ring on the turbosupercharger, it comprises retaining ring, described retaining ring is fixedly connected on the turbine case, wherein, be evenly equipped with a plurality of blades that are structure as a whole with retaining ring on the described retaining ring, described blade is the crescent shape structure, and adjacent two interlobate spaces form gas flow.
Especially, have at least on two in the described blade to offer tapped hole, by set screw retaining ring is connected on the turbine case.
Especially, have in the described blade on six blades and offer tapped hole.
The beneficial effects of the utility model are, compared with prior art describedly improve by the global shape to blade for the high-efficiency guide ring on the turbosupercharger, have the following advantages:
1) the engine fuel consumption rate has clear improvement in full condition range, and efficient is higher, usually improves 4%～6%.
2) reduced the impact of engine speed fluctuation on efficiency of turbocharger.
3) reduce operating temperature, reduce heat load, improved the working life of part.
4) whole aircraft reliability improves greatly.
Description of drawings
Fig. 1 is the structural representation of the wedge-like symmetrical blading on the traditional guide ring,
Fig. 2 be the utility model embodiment 1 provide be used for high-efficiency guide structure of rings schematic diagram on the turbosupercharger;
Fig. 3 is the sectional drawing that is used for the high-efficiency guide ring on the turbosupercharger that the utility model embodiment 1 provides;
Fig. 4 is the side view of the blade that is used for the high-efficiency guide ring on the turbosupercharger that provides of the utility model embodiment 1.
Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
See also Fig. 2 to shown in Figure 4, in the present embodiment, a kind ofly comprise retaining ring 1 for the high-efficiency guide ring on the turbosupercharger, be evenly equipped with a plurality of blades 2 that are structure as a whole with retaining ring 1 on the described retaining ring 1, have on six blades in the described blade 2 to offer tapped hole 3, set screw lock onto that tapped hole 3 is interior to be connected in retaining ring 1 on the turbine case.Described blade 2 is the crescent shape structure, and the space that adjacent two blades are 2 forms gas flow 4.
The space that described adjacent two blades for the high-efficiency guide ring on the turbosupercharger are 2 forms the most advanced and sophisticated flow area that forms of gas flow 4, two blade exits, and leaf curved surface is through-flow of gas, and efficiency of turbocharger is had significant impact.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1. high-efficiency guide ring that is used on the turbosupercharger, it comprises retaining ring, described retaining ring is fixedly connected on the turbine case, it is characterized in that, be evenly equipped with a plurality of blades that are structure as a whole with retaining ring on the described retaining ring, described blade is the crescent shape structure, and adjacent two interlobate spaces form gas flow.
