Abstract
Impeller wind guide chamber bypass recycling turbocharger air compressor, including compressor volute and impeller, compressor volute are equipped with inlet chamber A and diffusion chamber C, are impeller wind guide chamber B between compressor volute inlet chamber A and the backgear of impeller.It is equipped with plural number circle on the inner wall of compressor volute inlet chamber A and bypasses recycle tank, bypass recycle tank is located at the port of impeller wind guide chamber B, and the section for bypassing recycle tank is V-type.When impeller rotates and surge will occur, the most of air entered from compressor volute inlet chamber A enters diffusion chamber C through impeller wind guide chamber B, another fraction air then backs within the input end of impeller wind guide chamber B via bypass recycle tank, then enter diffusion chamber C after being re-introduced into impeller wind guide chamber B, it is final to realize that air-flow is continuous, reduce turbo-charger surge.
Description
Technical field
It is especially a kind of to be tied in impeller wind guide chamber using bypass recycling the utility model relates to turbocharging technology field
The turbocharger air compressor of structure.
Background technique
There is reduction engine fuel to consume, reduce exhaust gas discharge, improve engine power and recovery height for turbocharger
The effect of former power.But booster is in use, is especially easy to happen surge in highlands, surge is easy to cause increasing
Depressor breaks down, and eventually leading to engine cannot work.
Attached drawing 1 is the turbocharger arrangement schematic diagram of existing compressor volute structure, including compressor volute 1 and impeller
2, compressor volute 1 is equipped with inlet chamber A and diffusion chamber C, is leaf between 1 inlet chamber A of compressor volute and the backgear of impeller 2
Take turns wind guide chamber B.When turbocharger operation, air enters impeller wind guide chamber B by the inlet chamber A of compressor volute 1, then from
Impeller wind guide chamber B enters diffusion chamber C.When impeller 2 rotates and surge occurs, after air is inhaled into impeller wind guide chamber B, air-flow meeting
Discontinuously enter diffusion chamber C, causes turbocharger that surge occurs, break down to cause booster.
Summary of the invention
One kind is provided in impeller wind guide chamber using other the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art
The turbocharger air compressor of logical recirculation structure.
The technical solution of the utility model is: impeller wind guide chamber bypass recycling turbocharger air compressor, including calms the anger
Machine spiral case and impeller, compressor volute is equipped with inlet chamber A and diffusion chamber C, in the backgear of compressor volute inlet chamber A and impeller
Between be impeller wind guide chamber B.It is equipped with plural number circle on the inner wall of compressor volute inlet chamber A and bypasses recycle tank, bypass is followed again
Annular groove is located at the port of impeller wind guide chamber B, and the section for bypassing recycle tank is V-type.
When impeller rotates and surge will occur, the most of air entered from compressor volute inlet chamber A is through impeller
Wind guide chamber B enters diffusion chamber C, another fraction air then via bypass recycle tank back within impeller wind guide chamber B into
Mouth end enters diffusion chamber C after being then re-introduced into impeller wind guide chamber B, final to realize that air-flow is continuous, reduces turbocharger and breathes heavily
Vibration occurs.
The utility model has a characteristic that compared with prior art
Bypass recycle tank is added in the inner wall of compressor volute inlet chamber A, is not only able to avoid turbocharger
Surge prevents turbocharger from breaking down, additionally it is possible to simplify and reduce Compressor volute of turbocharger structure, reduce turbine
Supercharger air compressor spiral case purchase cost.
It is further described below in conjunction with detailed construction of the drawings and specific embodiments to the utility model.
Detailed description of the invention
Attached drawing 1 is existing turbocharger air compressor structural schematic diagram；
Attached drawing 2 is impeller wind guide chamber bypass recycling turbocharger air compressor structural schematic diagram；
Attached drawing 3 is the portion the I enlarged diagram in attached drawing 2.
Specific embodiment
Embodiment one, impeller wind guide chamber bypass recycling turbocharger air compressor, including compressor volute 1 and impeller 2,
Compressor volute 1 is equipped with inlet chamber A and diffusion chamber C, is impeller between 1 inlet chamber A of compressor volute and the backgear of impeller 2
Wind guide chamber B.It is equipped with three circles on the inner wall of 1 inlet chamber A of compressor volute and bypasses recycle tank 1-1, bypass recycle tank 1-1 is set
In the port of impeller wind guide chamber B, the section for bypassing recycle tank 1-1 is V-type.
When impeller 2 rotates and surge will occur, the most of air entered from 1 inlet chamber A of compressor volute is through leaf
Wheel wind guide chamber B enters diffusion chamber C, and another fraction air then backs within impeller wind guide chamber B via bypass recycle tank 1-1
Input end, be then re-introduced into after impeller wind guide chamber B and enter diffusion chamber C, it is final to realize that air-flow is continuous, reduce turbocharging
Device surge occurs.
Embodiment two, compared with embodiment one, unlike, on the inner wall of 1 inlet chamber A of compressor volute be equipped with four circle
Bypass recycle tank 1-1.
Claims (1)
