Definitions

  • the invention relates to a wheel in particular for a high peripheral speed centrifugal compressor made from pre-molded, sector-shaped buckets, juxtaposed and glued to each other in the circumferential direction to form a unitary assembly with high mechanical resistance to rupture.
  • a centrifugal compressor essentially consists of a rotor and a stator.
  • the .rotor has vanes rotating around an axis, responsible for driving the gas at their rotational speed, in order to communicate energy to it.
  • the stator in addition to constituting the casing of the machine, includes a part called a diffuser, responsible for transforming the pressure acquired by the gas into pressure.
  • the casing surrounding the rotor is of a relatively simple design.
  • closed-wheel rotors have the disadvantage of being limited in rotation speed (300 m / s for example), the external surface of revolution being subjected to greater centrifugal stresses than the blades, which leads to cracks between said blades and said outer surface, which increase with the speed of rotation.
  • wheels made of metal (steel, aluminum, titanium) are cast or mechanically welded, the first embodiment (cast) being more common in closed wheels and of small dimensions for reasons of weld accessibility.
  • the invention relates to a new compressor wheel having the originality of having both a high breaking strength, a low specific mass (allowing very high peripheral speeds and larger wheel diameters) without the need for an expensive manufacturing process or machining.
  • This object is achieved by making the wheel from pre-molded, sector-shaped troughs, made of fibers of high mechanical strength, coupled together, in a circumferential direction, by bundles of radiating wires coated with a bonding agent. and taking up the centrifugal forces, whatever the specific speed of the wheel.
  • the fibers used for the manufacture of the buckets and wire bundles are preferably fibers of carbon, boron, aromatic polyamides or glass, and the bonding or sealing agent can be advantageously chosen from epoxy resins, polyimides or phenolic.
  • the invention relates, (deviating from the drawbacks of metal wheels, cast or mechanically welded), a new type of wheel having, for a specifically low mass, a high resistance mechanical at break and therefore at bursting and thereby allowing larger diameters and higher peripheral speeds than those resulting from compressor wheels hitherto known.
  • the wheels of centrifugal compressors are generally formed by a rotor 1 defined by vanes 2, one of the ends 2 1 of which opens onto the front face called the "intake" face, the other end 2 2 communicating with a fixed diffuser 3 itself in relation to a peripheral volute 4.
  • the fluid entering the channel delimited by the blades acquires pressure and speed there, this speed being convertible into pressure in the diffuser.
  • the rotor is obviously rotated by a control shaft 5 to which it is coupled, several wheels can be stepped on the same shaft.
  • the wheel is made from buckets 6 (Fig. 2) having the particularity of being made of fibers having a high mechanical resistance to rupture, each bucket being in the form of a sector to define in itself a channel.
  • the wheel is of modular type, since it consists of a series of buckets 6 juxtaposed in a circumferential direction and made integral with one another, to form a stable unitary assembly, by bundles of radiating wires 9 coated with a liaison officer.
  • the fibers used for making the buckets are preferably carbon fibers, although boron fibers, aromatic polyamides or even glass fibers can also be used. These fibers indeed make it possible to envisage, because of their high mechanical strength, high specific speeds, but it is however necessary, given the unidirectional nature of the fiber, to use specific morphologies so that the centrifugal forces are transmitted in the direction of the fiber and not perpendicular to them.
  • Figs. 3 and 4 show the method of manufacturing a wheel according to the invention. It suffices to place in a star, on a marble 7 the troughs in the shape of a sector, taking care to leave between their lateral flanks 6 1 radial interstices 8,1 placement of the troughs being facilitated by stabilizing pins 6 2 are provided and which come to rest in the heel manner on the flat marble 7. Next, the buckets are coupled and sealed together by a stack of beams of radiating wires 9 previously coated with a bonding agent whose chemical nature is compatible with the material constituting the buckets and that constituting the wires, for example, an epoxy-type resin, if the buckets and the bundles of wires are based on carbon fibers.
  • a bonding agent whose chemical nature is compatible with the material constituting the buckets and that constituting the wires, for example, an epoxy-type resin, if the buckets and the bundles of wires are based on carbon fibers.
  • each radial gap 8 opens onto rods 11, integral with the marble and on which the connecting wires are wound.
  • This carbon fiber wheel can be coupled either to a metal axle, or to an axle also made of carbon fibers.
  • a metal axle or to an axle also made of carbon fibers.
  • axial channels obtained by pins 12 passing right through the wheel and which, when they are removed from the mold, form passages in which the fingers 13 forming the end of the drive shaft 14 will be introduced.
  • These fingers will be made integral with the wheel by a support plate 15 and bolts 16 fixed on the end of each of said fingers 13.
  • the drive shaft is made of carbon fibers, it will include, like the metal shaft, fingers 13, as illustrated in Fig. 5, but these will be positioned, inserted and sealed to the wheel, as the bundles of wires are stacked. It will suffice, in this case, that the plate 7 has a central opening for the passage of the shaft and that the fingers 13 are arranged between the axis 10 of the wheel and the ends of the buckets (as illustrated by the reference 12 in Fig. 3) so that the shaft is coupled to the wheel by coating the wires like the buckets. After cooling and removing the marble 7, the wheel and the drive shaft will form a unitary and homogeneous whole.
  • a cooking operation is then carried out in an oven, the temperature of which is defined by the type of resin used.
  • the buckets can be covered with a continuous tulip-shaped veil also produced from carbon fibers bonded leaving; of course free, the inlet openings of the buckets opening onto the front face of the wheel, the opposite end of said buckets communicating in known manner with a rotor diffuser having the general shape of an annular crown.
