Definitions

  • the invention relates to a gyroscope according to the preamble of claim 1. Furthermore, the invention relates to the use of such gyroscopes.
  • Rotary machines are known in which, for example, an axial compressor is connected upstream of a radial impeller.
  • Patent application WO 86/05557 describes such a pump / compressor for multi-phase conveying media, in which a mixer device is connected upstream of the axial compressor.
  • a fixed guide vane ring is arranged immediately following the first stage of the axial compressor and immediately upstream of the counter-rotating blade rings.
  • Such a construction is relatively space-consuming and, in addition, axial compressors have relatively high specific speeds and generate only a slight pressure increase in a wide speed range, which is favorable for the radial compressor connected downstream. A large number of stages are therefore necessary in order to achieve a sufficient pressure increase.
  • the object of the invention is to build a rotary machine which has a sufficient suction head with a compact design.
  • Another object of the invention is to provide a gyroscopic machine which, in particular, also ensures good conveying capacities for conveying multiphase mixtures, such as liquid-gas mixtures.
  • a rotary machine is characterized by the features in the characterizing part of claim 1.
  • the use according to the invention of such rotary machines is characterized in the feature of claim 17.
  • the dependent claims relate to particularly advantageous embodiments and uses of the rotary machine.
  • the design of the centrifugal machine as a radial compressor according to the invention is not a faulty construction, but is, for example, excellently suitable for conveying and compressing multi-phase conveying media, such as liquid-gas mixtures.
  • multi-phase conveying media such as liquid-gas mixtures.
  • Such mixtures which may also contain solid parts in a certain size and quantity, excellent mixing and compression of the compressible gas fractions is initially achieved.
  • segregation hardly occurs if the sub-stages are correctly coordinated.
  • the construction proposed according to the invention can be interpreted as a sequence of several stages, the specific speed of which increases from stage to stage in accordance with the reduction in the gas volume.
  • the formation of the last stage as a rotating diffuser leads to a decrease in the absolute speed of the conveying medium, in that the flow cross section increases in the direction of flow, that is to say radially outwards.
  • Losses in fixed diffusers are relatively high with multi-phase fluids, especially with liquid-gas mixtures.
  • the rotating diffuser has significantly lower losses.
  • fixed parts in zones with higher pressure gradients should be avoided in order to keep power losses in the centrifugal machine low.
  • the efficiency improves if there are no stationary elements in these zones by the Energy exchange losses between the phase components can thus be reduced.
  • the efficiency of the gyroscopic machine i.e. a machine with a more or less radial outflow of the conveyed liquid, for example, a multi-phase pump according to the invention, further increased and improved. Due to the radial outflow, the lowest possible absolute velocity of the fluid is achieved for a given outlet channel width. In such an embodiment, a total pressure increase in the last stage is largely dispensed with in favor of the lowest possible exit velocity of the conveying fluid.
  • Centrifugal machines according to the invention can fundamentally be used to convey a liquid-gas mixture with a change in the percentage composition between 0% and 100% gas (volume percent), the efficiency depending on the design of the centrifugal machine and mixture composition e.g. can vary between 70% and 5%.
  • the efficiency depending on the design of the centrifugal machine and mixture composition e.g. can vary between 70% and 5%.
  • consideration should be given to the impairment of the service life of individual machine parts. The operating range is therefore usually restricted by the required service life of machine parts.
  • a gyroscope for liquid-gas mixtures with a gas content (volume) in the range of approximately 20% to 60% (at the intake pipe inlet of the first stage) is advantageously used.
  • a pressure increase in the range of about 5 to 50 bar or even more can be achieved without further ado.
  • Steps of this type can also have so-called intermediate blades, for example likewise in tandem or multiple blade design.
  • the design according to the invention is suitable for rotary machines with impeller diameters in the range from 100 mm to 1500 mm, preferably in the range from 350 mm to 700 mm.
  • the circumferential speed should be in the range of approximately 80 m / s to 350 m / s if possible.
  • the centrifugal machine 1 designed as a pump and shown in a schematic axial section with the housing 10 has the two counter-rotating impellers 11 and 12.
  • the impeller 11 with the vane carrier disk 110 carries the two vane rings or vane grilles 111 and 112.
  • the impeller 12 with the vane carrier disk 120 carries the vane rings or vane gratings 121 and 122.
  • the vane rings of the two vane carrier disks 110 and 120 are interdigitated.
  • the attachment rotor / inducer 124 is also attached on the suction side.
  • the vane carrier disk 110 forms an inner housing together with the hollow shaft 13.
  • the diffuser 1113 In the area of the radial, outer end of the impeller carrier disk or blade carrier disk 110 is the diffuser 1113, which also rotates with the inner housing.
  • the conveying medium almost radially emerging from the diffuser 1113, enters the annular space 140, in which the deflection grid with the deflection blades 14 is arranged .
  • the delivery medium is thus deflected in the tangential direction, or at least in a direction which deviates from the tangential only by approximately 20 ° to 30 °.
  • the centrifugal machine or pump 2 of FIG. 2 is of conventional design in that it has no rotating inner housing in comparison with that in FIG. 1.
  • the two counter-rotating impellers 21 and 22 are arranged, which are attached to the shafts 25 and 26, respectively.
  • the rotating diffuser 23 is machined in the example of the blade carrier disc 210 shown.
  • the blade carrier disc 210 carries the blade rings 211 and 212 and the carrier disc 220 of the counter-rotating impeller 22 carries the blade rings 222 and 223.
  • the blade rings of the two blade carrier discs 210 and 220 are also arranged here in an interlocking manner.
  • the delivery fluid flows out of the diffuser 23 into the annular space 240 almost radially.
  • the delivery fluid flows out of the diffuser 23 into the annular space 240 almost radially.
  • FIG. 3 shows a schematic side view of the example of an annular space 30, in which a deflection, deflection or dispersion grid 31 with deflection, deflection or dispersion blades 32 is arranged.
  • the deflection takes place up to an angular range of 20 ° to 30 ° to the tangential.
  • FIG. 4 shows in a schematic axial section a gyroscopic machine which comprises three units 41, 42 and 43 arranged one behind the other. While the first, i.e. the input unit 41 is designed as a multi-stage, counter-rotating two-wheel pump, the downstream units 42 and 43 are designed as ordinary centrifugal pumps.
  • FIG. 5 shows a gyroscopic machine, which comprises three units 51, 52 and 53 arranged one behind the other, in a schematic axial section. All three units 51, 52 and 52 are multi-stage, opposing two-wheel turbo machines. This arrangement, as it could be used as a feed pump in a pipeline for oil or for a liquid-oil gas mixture, has additionally installed a turbine stage 54 with the turbine blade rings 541 and 542 in the last multi-stage, opposed two-wheel turbo unit 53.
  • the blade ring 543 contributes to increasing the centripetal pressure and at the same time assumes the function of a stator for the second turbine stage with the blade ring 542.
  • This rotary machine with three units comprises rotating inner housings 511, 521 and 531, which can be connected or coupled as a rotary unit .
  • the return channels of the second stage 52 and possibly also the first stage 51 could be provided with centripetal stages.
  • FIG. 6 shows a schematic axial section of a multi-stage, counter-rotating two-wheel turbomachine 6 with two units 61 and 62 in an encapsulated, double-flow design.
  • the drive machine 63 drives the rotating inner housing 65 and the drive unit 64 the inner rotor 66 equipped with blade rings on both sides.
  • the rotating diffuser 60 is common to the two units 61 and 62 and part of the rotating inner housing 65.
  • FIG. 7 shows the schematic longitudinal section through the rotating inner housing 72 and the counter-rotating inner rotor 73 of a multi-stage, counter-rotating two-wheel turbo unit 7, in which the leading edges 71 of the blades of the first stage are inclined with respect to the flow lines of the conveyed medium.
  • the impeller blades are double-curved. Both constructive measures contribute to an increased and improved homogenization of the phase mixture, e.g. Gas / liquid, at.
  • FIG. 8 schematically shows the supervision of a tandem or multiple blading (multiple blading) as they can be arranged on a blade carrier wheel.
  • intermediate blades 811, 821 and 831 which extend less radially inwards than the blades 81, 82 and 83.
  • All the blades 81, 82, 83 and intermediate blades 811, 821, 831 have intermediate channels Z.
  • the individual blade parts have a type of wing profile in cross section. The use of such constructions can be useful above all, but not only, in the first and possibly the second stage, because it can further improve the homogenization of a multi-phase delivery medium.
  • rotating diffusers and deflection grids in the annular space can also be used in those examples in which no explicit reference has been made. Only a single blade ring or a plurality of blade rings can be arranged on a blade carrier wheel. The number depends solely on the number of stages that a two-wheel compressor has. Likewise, the number of units connected in series can be different from that in the examples shown.
