Description
Technical field
What the present invention relates to is a kind of turbosupercharger, specifically the gas compressor of turbosupercharger.
Background technique
Centrifugal compressor uses the bleed recycling device to be widely used on high pressure ratio centrifugal compressor in advanced turbosupercharger both at home and abroad, and its Main Function is to widen the operating range of centrifugal compressor and enlarges its surge margin.Raising along with centrifugal compressor rotating speed and pressure ratio, its effective operating range sharply narrows down, after adopting its bleed recycling device, the centrifugal compressor flow during near the stall margin portion gas bleed by the groove of bleeding, flow into from return port again, so that the operating range of centrifugal compressor broadens, surge margin increases.
The bleed position of groove and size of bleed recycling device has conclusive impact to the increase of widening with surge margin of its operating range, there is different impacts the different groove positions of bleeding, the operating range of centrifugal compressor when traditional bleed recycling device often can not significantly be widened low-pressure ratio and high pressure ratio simultaneously for the expansion of the centrifugal compressor operating range under different rotating speeds.
Summary of the invention
The object of the present invention is to provide the operating range that effectively to widen simultaneously in centrifugal compressor low-pressure ratio and high pressure ratio situation and the multichannel centrifugal compressor bleed recirculation structure of surge margin.
The object of the present invention is achieved like this:
the multichannel centrifugal compressor bleed of the present invention recirculation structure, comprise spiral case, casing, impeller, spiral case respectively with casing, impeller is connected, in the space that spiral case and casing and impeller form, Diffuser is installed, primary blades, splitterr vanes, it is characterized in that: the first passage and the second channel that are provided for bleed recirculation on casing, first passage comprises that two outlets of first passage return flow line and first passage return flow line are first passage return port and the first passage groove of bleeding, the first passage groove of bleeding is arranged between primary blades leading edge and splitterr vanes, the first passage return port is arranged between primary blades leading edge and casing end, second channel comprises that two outlets of second channel return flow line and second channel return flow line are second channel return port and the second channel groove of bleeding, the second channel groove of bleeding is arranged between impeller blade outlet and Diffuser, the second channel return port is arranged between first passage return port and casing end.
The present invention can also comprise:
1, also comprise third channel, third channel comprises that two outlets of third channel return flow line and third channel return flow line are third channel return port and the third channel groove of bleeding, the third channel return port is between first passage return port and second channel return port, and the third channel groove of bleeding is bled between groove at bleed groove and second channel of first passage.
Advantage of the present invention is: the present invention can effectively widen operating range and surge margin in centrifugal compressor low-pressure ratio and high pressure ratio situation simultaneously by using the bleed recirculation structure of 2 passages or the multichannel diverse location size more than 2.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
Mode of execution 1:
In conjunction with Fig. 1, the present invention is a kind of novel centrifugal gas compressor bleed recirculation structure, comprises the return port 11, the return flow line 12 of first passage etc. of bleed groove 10, first passage of return flow line 9, the second channel of return port 8, the second channel of bleed groove 7, the second channel of centrifugal compressor spiral case 1, centrifugal compressor casing 2, centrifugal compressor primary blades leading edge 3, centrifugal compressor splitterr vanes leading edge 4, centrifugal compressor impeller 5, centrifugal compressor vane diffuser 6, first passage.It is main is characterised in that between primary blades leading edge 3 and splitterr vanes 4 have the groove of bleeding of first passage, suitable size is selected in the flowing current separation of bleeding of first passage and the operating range of widening the part rotating speed can effectively be improved in the position, first passage is often all different to the raising degree of whole centrifugal compressor operating range to the lifting of whole operating range, often obvious in the slow-speed of revolution and intermediate speed zone lifting, general in the lifting effect of high speed area.Second channel bleed groove 10 between impeller blade outlet and diffuser vane 6, slightly different according to concrete centrifugal compressor position, the groove of bleeding can be arranged on impeller blade outlet following position.The groove of bleeding of second channel is as long as select suitable size and position according to concrete centrifugal compressor, also can promote the operating range under each rotating speed of whole centrifugal compressor, but the bleed circulation means of second channel during for the high rotating speed of centrifugal compressor the lifting effect of operating range better, during for the slow-speed of revolution, the lifting effect of operating range is general, in order to reach operating range and the surge margin of widening simultaneously under each rotating speed of centrifugal compressor, present embodiment has been selected a kind of centrifugal compressor bleed recirculation structure of 2 passages.
Mode of execution 2:
On the basis of mode of execution 1, increase again a passage, it is third channel, third channel comprises third channel return flow line, third channel return port and the third channel groove of bleeding, the third channel return port is between first passage return port and second channel return port, and the third channel groove of bleeding is bled between groove at bleed groove and second channel of first passage.
