Definitions
- the invention relates to an impeller of a turbo compressor, for rotation about an axis, comprising an inlet cross section for the substantially axial inflow of a product zessfluids in the impeller, comprising a discharge cross ⁇ section for substantially radial outlet of the process fluids from the
- An impeller comprising a wheel disc, which defines a hub-side Umlenkkontur of the axial flow direction in the radial flow direction, comprising mounted on the wheel blades, at least over a portion of the flow path of the process fluid through the impeller flow channels from an inlet edge to an exit edge
- ⁇ defined circumferential direction, each blade at a proximal to the wheel extension end edge defines a direction in the flow direction linear In ⁇ nenspur, such that on both sides of the inner track orthogonal equal distances to a Schaufeloberfl surface on a pressure side or a suction side of the blade, wherein the blade at
- This turbo compressor type is also referred to as a centrifugal compressor, because the conveyed process fluid is accelerated radially outward in the impeller as a result of centrifugal forces.
- mechanical energy is added to the gas or the process fluid for the purpose of compaction by means of a rotating blading of the impeller.
- the aspirated process fluid is delayed within the flow channels of the impeller formed between the individual blades relative to the movement of the impeller and thus compressed according to the physical laws of the flow mechanism to a higher pressure level. Since that is
- the fluid is further retarded after it has flowed out of the impeller in the radial direction in a subsequent diffuser and additionally compacted in accordance with the laws of Bernoulli in this way.
- a blade is geometrically initially designed to be larger than it is normally used, this 3-dimensional figure extending beyond the boundaries of the leading edge, trailing edge, wheel disc and cover disk consisting of a pressure side and a suction side is referred to as a definition surface
- this definition surface of the blade is used, which by means of the angular distribution at the Wheel disc and the cover plate and the Schaufeldickenvertei ⁇ ment is described. Within certain limits, partial surfaces are extracted from this definition surface, depending on the wheel disc and cover disc geometry, and used in an individual impeller design.
- Geometrical data such as axial, radial, tangential or circumferential direction always refer to a rotational axis of the impeller, unless the reference is otherwise stated.
- the invention has set itself the task of developing an impeller for a turbocompressor such that the efficiency over conventional wheels for the same purpose is improved.
- Blade lengths allow for the inclusion of positions of the inner track and the outer track with respect to the respective relative distances or proximity to the leading edge and trailing edge.
- the invention provides an advantageous geometry of wheels both for so-called closed Laufrä ⁇ der (wheels with a cover plate) and for so-called ⁇ fene wheels, which have no cover plate.
- the before ⁇ ferred embodiment of the invention are impellers with a Cover disc, which defines the flow channels adjacent to the extension end edges ⁇ of the blades and is attached to the blades in the region of the extension end edges of the blades.
- the linear inner track extends along an extension end edge of the blades which is distal from the wheel disc, between the entry edge and the exit edge.
- the open flow channels of the open impeller border on a stator contour, sealing the openings distal to the wheel disc, so that the fluidic boundary conditions are similar for purposes of the invention.
- the geometry according to the invention is particularly advantageous if the course of the meridional angle is monotonically decreasing between 10% and 90% of the relative blade length of the outer track.
- the findings of the invention indicate that the efficiency of the impeller can be increased if, in contrast to the inner track, the outer track no local
- An advantageous development of the invention provides that in the range between 10% and 90% of the relative blade lengths, the maximum difference between the inner track and the outer track for a specific position along the relative blade lengths of the meridional angle between 10 ° and 25 °.
- the meridional angle distribution on the inner track and the outer track differ significantly.
- the maximum difference does not mean the highest possible difference, but the highest actually occurring difference.
- the invention thus provides in this vorteilhaf ⁇ th development that an actual maximum difference occurs, which is between 10 ° and 25 ° between the inner track.
- Another advantageous development of the invention provides that the trailing edge of the blades is not inclined with respect to a meridional plane. Accordingly, it is proposed that the trailing edge of the blade include an angle with a meridional plane between 0 ° to 5 °.
- the blade inlet edge forms an angle between 35 ° to 45 °, preferably 41 ° with a radial plane.
- the entry ⁇ edge of the blade is thus something to ⁇ back offset from the inflow into the impeller.
- a particularly advantageous embodiment of the invention provides that in the range between 10% to 90% of the relative
- Blade length of the course of the meridional angle of the inner track has a turning point between 40% to 80% of the relative blade ⁇ length.
- the geometry recognized as advantageous in this manner contributes to a further improvement in the efficiency of the fluid mechanics on the blade of the impeller according to the invention.
- the profile of a blade thickness distribution of the inner track in the direction of flow should preferably be monotonically increasing.
- the blade ⁇ thickness distribution can be selected to be constant on the outer track substantially.
- the meridional angle of the outer track changes in the definition range between -20% (still outside the actual bucket) to + 20% by less than 5%.
- the curvature of the outer track is nearly constant in this area.
- the meridional angle can preferably be maximized at the blade inlet 3.
- the range of the largest change in outside track angle is between -20% and + 20%.
- the angle change is reversed downstream or to ⁇ taken back. In this way load from the deck ⁇ disc-flow is taken out, thereby avoiding the further course burbling.
- a preferred maximum angular difference between inner and outer track of 10 ° -25 ° in the range of a meridional extent of 15% to 45% is present, preferably between 25% - 35%.

- Meridional angle ⁇ ⁇ according to the relative blade length BL for the inner track IT and the outer track OT.
- the blade leading edge LE here forms an angle LEA of 41 ° with a radial plane RP.
- the leading edge of the blade B is accordingly somewhat Jenkinsver ⁇ sets.
- FIG. 4 shows the blade thickness distribution as a course over the relative blade length BLL for the inner track IT and the outer track OT.
- Exemplary Fi gur shows 5 details on such feathering at a leading edge of a wheel disc or cover disc in a specific ⁇ matic memoristangential bain from a radial point of view.
