Plural blade 36 is distributed in the week side of boss of the inlet end 38 in wheel compresses area 12, so that the inlet air flow entered from air inlet 13 is discharged via the plural blade 36 into wheel compresses area 12, and after the impeller sets 11 compression from gas outlet 14.
Specifically, the week side of boss of inlet end 38 of the plural blade 36 along wheel compresses area 12 circumferentially array distribution, and form a blade group, and the axis of the plural blade 36 is parallel to each other.
Drive mechanism is connected with the plural blade 36, for driving each blade 36 to rotate, to change the established angle of blade 36.
It should be noted that according to techniques known, the established angle of blade 36 refers to the tangent line and the angle of circumferencial direction of the aerofoil profile bone line of blade 36 at import.
It can be seen that, in the present embodiment, in order to obtain smaller volume flow, it is realized by the change to the air-flow of air inlet side, and is not related to the change to outlet side.The structure in wheel compresses area 12 is not changed in the present embodiment, so the present embodiment no longer deploys to describe to the structure in wheel compresses area 12.
Alternatively, the form of drive mechanism has a variety of, and the present embodiment only symbolically provides a kind of drive mechanism, referring to Fig. 4 and Fig. 5.Fig. 4 is the structural representation of the drive mechanism of the present embodiment.In order to more intuitively express the composition of drive mechanism, Fig. 5 provides the three-dimensional structure diagram of the drive mechanism of the present embodiment.
The drive mechanism of the present embodiment includes driver 31, drive shaft 32, gear train and plural connecting shaft 37.
Specifically, driver 31 can be located at the outside of pipeline compressor 10, can also be located at the inner side of pipeline compressor 10, it carrys out driving blade 36 and rotated by receiving electric signal.In the present embodiment, driver 31 is located at the outside of pipeline compressor 10.
Drive shaft 32 passes through the machine wall of pipeline compressor 10, and its one end is connected with the driver 31, so as to being rotated by driver 31.
Gear train is connected with the other end of drive shaft 32.
The quantity of connecting shaft 37 is identical with the quantity of plural blade 36, and axis of each connecting shaft 37 along correspondence blade 36 is fixedly connected with blade 36；And the plural connecting shaft 37 is connected with gear train.
Specifically, gear train can be a variety of type of belt drive, and the present embodiment schematically lists a kind of structure of gear train, including：One first travelling gear 33, one second travelling gear 34 and plural 3rd travelling gear 35.

It is to be understood that the center line of the axis of blade 36, i.e. blade 36 around rotation.
Herein, " first ", " second " " etc. is only used for mutual differentiation, rather than represents significance level and order and the premise existed each other etc..
In the present embodiment, the first travelling gear 33, the second travelling gear 34 and the 3rd travelling gear 35 are spur gear.In other embodiments, the first travelling gear 33, the second travelling gear 34 and the 3rd travelling gear 35 can also be other types of gear.Specific gear-type is not defined herein.First travelling gear 33 and the second travelling gear 34 are external toothing, and the second travelling gear 34 and the 3rd travelling gear 35 are internal messing.
By this structure, driver 31 drives drive shaft 32 to rotate, and drive shaft 32 drives the first travelling gear 33 to rotate；Then the effect of engagement is passed through, first travelling gear 33 drives the second travelling gear 34 to rotate, second travelling gear 34 drives plural 3rd travelling gear 35 to rotate simultaneously simultaneously, each 3rd travelling gear 35 drives blade 36 to rotate, so as to change the established angle of all blades 36 simultaneously, the regulation of complete blade pair 36, this is simple to operate.
Certainly, only symbolically drive mechanism is illustrated for the present embodiment, removes outside gear-driven form, and drive mechanism can also be the structure of other forms, such as, but not limited to V belt translation, Chain conveyer etc..
Fig. 6 shows the performance chart of the pipeline compressor 10 of the present embodiment, and it identifies pipeline compressor 10 under 70% rotating speed, the established angle of blade 36 is -10,0,10,20,30,40,50,60 degree when pipeline compressor performance curve.Wherein, the performance curve of the pipeline compressor when established angle of blade 36 is 0 degree, that is, the performance curve of the pipeline compressor in Fig. 1 under 70% rotating speed.Wherein, the ordinate P in Fig. 6 is that outlet pressure, abscissa S are that standard volume flow, D are thermal design point.
As seen from Figure 6, the region between the performance curve of Far Left (established angle of blade 36 is 60 degree) and rightmost (established angle of blade 36 is -10 degree) is the working region of pipeline compressor 10 in the present embodiment.It can be seen that, by setting the blade group that plural blade 36 is constituted in inlet channel, minimum volume flow is about the 45% of design volume flow, so that compared with prior art, volume flow reduction makes volume flow adjustable range wider.
Alternatively, in order to play the protective action to the first travelling gear 33, the second travelling gear 34 and the 3rd travelling gear 35, the pipeline compressor 10 of the present embodiment can also further comprise：End cap 39, the end cap 39 is fixedly connected with the inwall of pipeline compressor 10 and is coaxially disposed with central shaft 20.The inwall of end cap 39 and pipeline compressor 10 is surrounded to form a cavity, and the first travelling gear 33, the second travelling gear 34 and the 3rd travelling gear 35 are placed in the cavity.
Alternatively, wheel compresses area 12 is entered in order to ensure that air-flow can be smoothly through inlet end 38, without forming turbulent flow in air inlet 13, pipeline compressor 10 can also further comprise：Kuppe 21, kuppe 21 is coaxially disposed with central shaft 20, and one end of kuppe 21 is fixedly connected with end cap 39, the other end of kuppe 21 is extended at inlet end 38.
Referring to Fig. 5, in the present embodiment, the cross section of kuppe 21 is gradually reduced along the direction close to the inlet end 38.
Certainly, when actual use, the cross section of kuppe 21 can also be other forms, gradually increase again after being such as gradually reduced, can guarantee that air-flow smoothly enters inlet end 38.
The structure of the above-mentioned pipeline compressor for being the present embodiment.By the pipeline compressor of the present embodiment, minimum volume flow when can make the pipeline compressor work is less than the 50% of design volume flow, so as to meet the demand of client.
It can be seen that from such scheme, the pipeline compressor 10 of the present invention, by setting plural blade 36, it is formed with the gas channel of 12-gas outlet of air inlet 13-blade, 36-wheel compresses area 14, the plural blade 36 can play the guide functions to inlet air flow, so as to so that pipeline compressor 10 is in the range of speeds of permission, obtain the volume flow smaller than prior art.
Also, by changing the established angle of blade 36, it just can change volume flow when pipeline compressor 10 is run, without independent Pivot axle 20, just can obtain broader volume flow adjustable range.
In addition, the plural blade 36 being distributed by the circumference array, can preferably play a part of water conservancy diversion, and avoid the occurrence of turbulent flow.
Again, in the present embodiment end cap 39 setting, protective action can be played to the first travelling gear 33, the second travelling gear 34 and the 3rd travelling gear 35.
In addition, by the kuppe 21 in the present embodiment, entering wheel compresses area 12 to ensure that air-flow can be smoothly through inlet end 38, without forming turbulent flow in air inlet 13.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection.
