Background technique
Known a kind of compressor set from file DE 10 2,009 016 392 A1, it is with Axial Flow Compressor and radial flow compressor, and this Axial Flow Compressor and radial flow compressor are axially one after the other arranged on common axle.Correspondingly be arranged in common live axle place according to the assembly of the assembly of rotor-side of one or each Axial Flow Compressor level of file DE 10 2,009 016 392 A1 Axial Flow Compressor and the rotor-side of of radial flow compressor or each radial flow compressor level to be fixed on or rather on common live axle.
The pressure initiation (Druckaufbau) possible to greatest extent of such compressor set is restricted in rotor dynamic.Therefore pressure initiation is in particular by the natural frequency of the assembly of the rotor-side of compressor set, rigidity and damping characteristic restriction.
The feature of the compressor set formed by Axial Flow Compressor and radial flow compressor (it is axially one after the other arranged in common live axle) known is up to now, live axle has approximately uniform diameter in the region of Axial Flow Compressor and radial flow compressor.This also draws from the sketch of DE 10 2,009 016 392 A1.
Need such compressor set, namely can be formed relative to known compressor set adherence pressure by means of this compressor set.
Model utility content
Be as starting point target of the present utility model, create a kind of novel compressor set.This target is solved by compressor set according to claim 1.According to the ratio between the minimum runoff formula impeller base diameter in the region at radial flow compressor of the maximum diameter of the utility model in the region at Axial Flow Compressor of axle and axle between 1.5 and 3.0.
The utility model is utilized to advise, increase the diameter in the region of axle at Axial Flow Compressor when common axle for the compressor set formed by Axial Flow Compressor and radial flow compressor, like this or rather, namely the maximum diameter being arranged in the region of Axial Flow Compressor of axle is compared to the minimum runoff formula impeller base diameter being arranged in the region of radial flow compressor large at least 50% of axle.Therefore can increase available pressure initiation on the one hand relative to known compressor set, the structure length of such compressor set can be shortened on the other hand.
Ratio between minimum runoff formula impeller base diameter in maximum diameter preferably in the region at Axial Flow Compressor of axle and the region at radial flow compressor of axle is between 1.8 and 3.0.This ratio between the diameter of axle is preferred in particular.
Accompanying drawing explanation
From dependent claims and below explanation obtain preferred improvement project of the present utility model.Explain embodiment of the present utility model in detail by means of drawing, but be not restricted to these embodiments.Wherein:
Fig. 1 shows the schematic perspective view according to compressor set of the present utility model.
List of reference characters
1 compressor set
2 Axial Flow Compressors
3 radial flow compressors

5 rotor blades
6 radial flow impellers.
Embodiment
The utility model relates to the compressor set formed by the radial flow compressor of the Axial Flow Compressor of at least single-stage and at least single-stage.
Fig. 1 show the assembly of the rotor-side of the embodiment according to compressor set 1 of the present utility model schematically, the side view of perspective, wherein the compressor set 1 of Fig. 1 comprises multistage Axial Flow Compressor and multistage radial flow compressor 3.Seven Axial Flow Compressor levels are comprised at shown embodiment's axis streaming compressor 2, and radial flow compressor 3 comprises two radial flow compressor levels, wherein Axial Flow Compressor 2 and radial flow compressor 3 axially one after the other act on (angreifen) or rather adjacent to each other at common axle 4 place.Therefore Fig. 1 shows, and the rotor blade 5 of the rotor-side of Axial Flow Compressor 2 and the radial flow impeller 6 of radial flow compressor level 3 axially one after the other act on adjacent to each other or rather and be fixed on common axle 4 place or rather.
When according to of the present utility model compressor set 1 in the maximum dimension D A-MAX in the region of Axial Flow Compressor 2 of axle 4 and the ratio between the minimum runoff formula impeller base diameter DR-MIN in the region of radial flow compressor 3 of axle 4 between 1.5 and 3.0.
Be in the region of the last Axial Flow Compressor level of Axial Flow Compressor 2 at the maximum dimension D A-MAX being arranged in the region of Axial Flow Compressor 2 of the preferred embodiment axis 4 of the utility model display, the minimum runoff formula impeller base diameter DR-MIN being arranged in the region of radial flow compressor 3 of axle 4 is in the region of first radial flow compressor level of radial flow compressor 3.That as above sets forth is such, ratio between diameter DA-MAX and DR-MIN is between 1.5 and 3.0, thus the minimum runoff formula impeller base diameter DR-MIN at least large 50% that be arranged in the region of radial flow compressor 3 of most diameter DA-MAX compared to axle 4 being arranged in the region of Axial Flow Compressor 2 of therefore axle 4.
According to the favourable improvement project of the utility model in the maximum dimension D A-MAX in the region of Axial Flow Compressor 2 of axle 4 and the ratio between the minimum runoff formula impeller base diameter DR-MIN in the region of radial flow compressor 3 of axle 4 between 1.8 and 3.0.
According to the ratio of the first favourable improvement project of the present utility model between the diameter DA-MAX and diameter DR-MIN of axle 4 between 2.0 and 3.0.
According to the ratio of another favourable improvement project of the present utility model between the diameter DA-MAX and diameter DR-MIN of axle 4 between 1.8 and 2.5.
According to the ratio of another favourable improvement project of the present utility model between the diameter DA-MAX and diameter DR-MIN of axle 4 between 2.0 and 2.5.
When being arranged in above-mentioned scope at the maximum diameter in the region of Axial Flow Compressor 2 of axle 4 and the ratio between the minimum runoff formula impeller base diameter in the region of radial flow compressor 3 of axle 4, double relative to attainable pressure initiation being made to exceed from compressor set well known in the prior art.
