Description
Technical field
The utility model is related to turbo-charger technical field, particularly a kind of compressor volute.
Background technology
Turbocharging technology is the energy that waste gas is discharged using engine, drives turbine wheel to rotate by turbine rotation and becomes
For mechanical work, coaxial compressor impeller also runs at high speed at a same speed with turbine wheel, after compresses fresh air, send
Enter cylinder, improve the atmospheric density and aeration quantity of cylinder, so as to improve the power of engine, improve combustion
The burning condition of oil, makes fuel oil fully burn, thus reduces fuel consumption, reduces nuisance in the waste gas for be discharged into air
Ratio, and then environmental protection and energy saving are finally realized, the effect of engine power is improved, while playing extensive when plateau works to engine
The effect of complex power.
In order to improve power per liter, reduction oil consumption and the discharge of engine, one of them relatively effective method is exactly to optimize
Turbocharger is matched, booster gross efficiency is improved.And the gross efficiency of booster includes compressor efficiency, compressor efficiency is improved
Booster gross efficiency can be improved.Reduce air flow loss of the air in compressor, so that it may improve compressor operating efficiency.
At present, compressor volute air inlet has three kinds of forms, and one kind is cylindrical hole, as shown in Figure 1, compressor volute 1
Air inlet 1-1 be cylindrical hole.Second is that conical bore combines shape with cylindrical hole, and as shown in Figure 2, compressor volute 1 enters
Gas port is combined by conical bore 1-2 with cylindrical hole 1-3, and cylindrical hole 1-3 is connected with conical bore 1-2 small end, and its joint portion is adopted
Use arc transition.The third is big cylindrical hole, conical bore and small cylindrical opening combination shape, as shown in Figure 3, compressor volute 1
Air inlet is combined by big cylindrical hole 1-4, conical bore 1-5 and small cylindrical opening 1-6, conical bore 1-5 big end and big cylindrical hole
1-4 connections, its joint portion uses arc transition, and small cylindrical opening 1-6 is connected with conical bore 1-5 small end, and its joint portion is using circle
Arc transition.
There is same problem in the air inlet of these three forms, be exactly compressor volute air inlet air flow field it is not equal enough
Even, air current flow loss is larger, reduces the operating efficiency of compressor.
The content of the invention
The purpose of this utility model is to overcome the above-mentioned not enough of prior art and provide a kind of use lemniscate air inlet
Compressor volute, can improve the uniformity of air flow field in compressor volute using lemniscate air inlet, reduce air flow
Loss, improves the operating efficiency of compressor.
The technical solution of the utility model is：Using the compressor volute of lemniscate air inlet, the air inlet of compressor volute
Mouth is combined by lemniscate air admission hole and cylindrical hole, and the gas outlet of lemniscate air admission hole and the air inlet of cylindrical hole are connected, double
The gas outlet diameter of knob line air admission hole and the diameter of cylindrical hole are all D1, and D1 is slightly larger than the diameter D2 of compressor impeller inlet end,
To ensure that compressor impeller can normally rotate in cylindrical hole.
Lemniscate air admission hole is lemniscate shape, and a length of L1 in hole of lemniscate air admission hole, the air inlet of lemniscate air admission hole is straight
Footpath D and lemniscate press the gas outlet diameter D1 determinations of lemniscate equation, the long L1 in hole of lemniscate air admission hole and lemniscate air admission hole,
And hole long L1, air inlet diameter D of the compressor characteristics to lemniscate air admission hole are calculated by compressor characteristics experimental test or CAE
And lemniscate is modified, with air flow loss in compressor, at least i.e. compressor efficiency is up to optimal selection.
The utility model has following features compared with prior art：
The air inlet of compressor volute is designed as lemniscate shape, and its shape is adapted to air stream, more cylindrical or cone
Flow field evenly, can reduce flow losses of the air in compressor inlet, improve the operating efficiency of compressor.
Detailed construction of the present utility model is further described below in conjunction with the drawings and specific embodiments.
Brief description of the drawings
Accompanying drawing 1 is the compressor volute structural representation of air inlet cylindrical hole；
Accompanying drawing 2 is that air inlet is that conical bore combines shape compressor volute structural representation with cylindrical hole；
Accompanying drawing 3 is that air inlet is big cylindrical hole, conical bore and small cylindrical opening combination shape compressor volute structural representation；
Accompanying drawing 4 is the compressor volute structural representation using lemniscate air inlet；
Accompanying drawing 5 is lemniscate air inlet compressor volute and compressor impeller scheme of installation.
Embodiment
Using the compressor volute of lemniscate air inlet, the air inlet of compressor volute 1 is by lemniscate air admission hole 1-7 and circle
Post holes 1-8 is combined, and lemniscate air admission hole 1-7 gas outlet is connected with cylindrical hole 1-8 air inlet, lemniscate air admission hole 1-
7 gas outlet diameter is all D1 with cylindrical hole 1-8 diameter, and D1 is slightly larger than the inlet end 2-1 of compressor impeller 2 diameter D2, with
Ensure that compressor impeller 2 can normally rotate in cylindrical hole 1-8.
Lemniscate air admission hole 1-7 be lemniscate shape, the lemniscate air admission hole 1-7 a length of L1 in hole, lemniscate air admission hole 1-7's
Air inlet diameter D and lemniscate are gone out by lemniscate equation, lemniscate air admission hole 1-7 hole long L1 and lemniscate air admission hole 1-7
Gas port diameter D1 is determined, and calculates compressor characteristics to lemniscate air admission hole 1-7's by compressor characteristics experimental test or CAE
The long L1 in hole, air inlet diameter D and lemniscate are modified, and are at least compressor efficiency highest with air flow loss in compressor
For optimal selection.
