Abstract
The utility model provides a kind of supercharger outlet structure, including ontology, and the ontology includes first end and second end, passes through the divergent segment to be formed for fluid outflow that is connected smoothly between the first end and the second end；The divergent segment is formed with boss mounting device at the position close to the second end, and the boss mounting device includes boss and shrinkage pool, and is formed with dowel hole on the annular end face of the second end.The supercharger outlet structure of the utility model is due to using diverging shape, and so as to which turbine end outlet pressure is effectively reduced, the exhaust resistance after reducing turbine increases expansion ratio of turbine, promotes exhaust energy and recycles ability.
Description
Technical field
The utility model relates to a kind of supercharger outlet structures, and in particular to a kind of gradually expanded form supercharger outlet structure.
Background technique
Existing spiral casing of pressure booster export structure, including spiral case, rotation is provided with whirlpool impeller in spiral case inner cavity, in spiral case
Volute outlet is provided on shell, the blade inlet edge of whirlpool impeller is placed in volute outlet, mostly uses volute outlet inner wall to be formed non-
Equal inner surface contours (i.e. straight mouth), the structure type is simple, convenient for manufacture, but easily forms air-flow interference in exit, influences efficiency.
Utility model content
In view of the above technical problems, the utility model provides a kind of supercharger outlet structure, and the structure is due to using flaring
Type can reduce inter-stream interference of working off one's feeling vent one's spleen, and promote turbine efficiency.
The technical solution adopted in the utility model are as follows:
The utility model provides a kind of supercharger outlet structure, including ontology, and the ontology includes first end and second end,
Pass through the divergent segment to be formed for fluid outflow that is connected smoothly between the first end and the second end；The divergent segment exists
Boss mounting device is formed at the position of the second end, the boss mounting device includes boss and shrinkage pool, and
Dowel hole is formed on the annular end face of the second end.
Optionally, the angle between the wall surface and axial direction of the divergent segment is about 10 °.
Optionally, the thickness of the boss is greater than the wall thickness of the divergent segment.
Optionally, the boss with a thickness of about 7mm, the wall thickness of the divergent segment is about 6mm.
Optionally, the shrinkage pool is located on front side of the boss, and in axial direction opens up to be formed.
Optionally, the dowel hole is formed in the middle position of the annular end face.
Supercharger outlet structure provided by the embodiment of the utility model, due to using diverging shape, so as to effectively drop
Low turbine end outlet pressure, the exhaust resistance after reducing turbine, increases expansion ratio of turbine, promotes exhaust energy and recycles ability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of supercharger outlet structure provided by the embodiment of the utility model.
Specific embodiment
In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing
And specific embodiment is described in detail.
Fig. 1 is the structural schematic diagram of supercharger outlet structure provided by the embodiment of the utility model.As shown in Figure 1, this reality
A kind of supercharger outlet structure, including ontology are provided with novel, the ontology includes first end 1 and second end 6, the first end
Pass through the divergent segment 2 to be formed for fluid outflow that is connected smoothly between 1 and the second end 6；The divergent segment 2 is close to institute
It states and is formed with boss mounting device at the position of second end 6, the boss mounting device includes boss 4 and shrinkage pool 3, and in institute
It states and is formed with dowel hole 5 on the annular end face of second end 6.
Specifically, first end 1 is located at the front end of export structure, and automatic pressure intensifier spiral case tail portion extends to form, and is export structure
Section minimum at, second end 6 is located at the rear end of export structure, for connect vent connection or exhaust butterfly valve, for outlet knot
The section maximum of structure.Angle between the wall surface of divergent segment 2 and the axial direction A A of export structure is about 10 °, divergent segment 2
Uniform wall thickness is about 6mm.
Boss mounting device is used to connect vent connection or is vented butterfly valve, and the thickness of boss 4 is greater than the divergent segment 2
Wall thickness, be about 7mm.Shrinkage pool 3 is formed in the front side of boss 4, shrinkage pool 3 is slot-type openings structure, slotting position and axis water
Flat, i.e., in axial direction AA opens up to be formed.
Dowel hole 5 is formed on the annular end face of second end, specifically be may be formed at the middle position of annular end face, is used for
Vent connection or the positioning and connection for being vented butterfly valve.In one example, the diameter of dowel hole 5 is about φ 4mm.
The supercharger outlet structure of the utility model has the advantage that 1, is designed by flaring type turbine outlet, together
The excessive face structure of Shi Youhua turbine outlet, can make turbine outlet gas inter-stream interference smaller, reduce to booster turbine
Operating influences, and promotes turbine efficiency.2, it is designed by flaring type turbine outlet, turbine end outlet pressure can be effectively reduced,
Exhaust resistance after reducing turbine increases expansion ratio of turbine, promotes exhaust energy and recycles ability.The design of flaring type turbine outlet
Turbine efficiency 1% can be promoted, engine consumption 0.5% is reduced, reduces customer using cost, reduces CO2 emission
Amount.
Embodiment described above, only specific embodiment of the present utility model, to illustrate the technology of the utility model
Scheme, rather than its limitations, the protection scope of the utility model are not limited thereto, although practical to this with reference to the foregoing embodiments
It is novel to be described in detail, those skilled in the art should understand that: any technology people for being familiar with the art
Member within the technical scope disclosed by the utility model, can still modify to technical solution documented by previous embodiment
Or variation or equivalent replacement of some of the technical features can be readily occurred in；And these modifications, variation or replacement,
The spirit and scope for the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution should all cover at this
Within the protection scope of utility model.Therefore, the protection scope of the utility model is answered described is with scope of protection of the claims
It is quasi-.
