Definitions

  • Figure 2a is a cross-sectional side view of the main components of the axial flow motor.
  • the present invention is a compact device for gas compression driven by an axial flow synchronous electric motor with no use of any kind of lubricants.
  • the rotating section of a first magnetic radial bearing 6 is formed by one or more permanent magnets with ring geometry and is mounted on one end or near to an end of the axis 5.
  • the rotating section of a second magnetic radial bearing 7 is formed by one or more magnets with ring geometry and is mounted on one the opposite end or near to the end opposite end of the axis 5.
  • Said rotating sections of radial bearings are part of the rotor.
  • a second stator section is formed by permanent magnets with ring or cylinder geometry that circumferentially surround the rotating sections and are fixed to the housing (not shown).
  • the zone where the axial flow motor 2 is located is crossed by the low pressure-low temperature gas.
  • This gas flow allows removing the heat generated in the motor, acting as a coolant.
  • the gas enters a first compression stage formed by an impeller 1 and its corresponding diffuser.
  • the rotor contains a second impeller 14 immediately crossed by the gas after the first one.
  • the gas increases its pressure and temperature until it enters a high pressure collector 17 and is conducted to a discharge connection of the stator.
  • Other embodiments of the invention may contain more or fewer impellers, as well as more or fewer assemblies forming the axial flow motor, according to each specific application.
  • the gas temperature at the entrance is low enough to act as a coolant of the power electronics in charge of commanding the electric motor.
  • a series of power electronic components 19 is placed out of the gas pressure containment 16 and is thermally linked thereto. Said electronic components take advantage of the thermal conductivity of metal forming the pressure containment to be cooled with the same process gas.
  • a cap 18 externally covers the power electronics to protect it from dust and ambient moisture.
  • Other embodiments of the invention may locate said electronic components directly inside the pressure contention, flooded by the process gas.
  • Other different embodiments may use other conventional and independent methods to cool the power electronics in case the gas temperature at the entrance of the compressor is extremely high.
  • the present device uses an electric, synchronous, axial flow motor with permanent magnets as driving force mounted on the same axis as the impellers of the centrifugal compressor. This type of motor is more efficient and has higher power density than high speed radial flow motors, which gives this device a superior global performance and a smaller physical size compared to the current art.

Abstract

L'invention concerne un dispositif compact de compression de gaz comprenant : a) un ou plusieurs compresseurs centrifuges ; et b) un moteur électrique synchrone à aimant permanent à flux axial à grande vitesse. Le moteur électrique et le compresseur sont directement couplés sur un seul axe et supportés par des paliers magnétiques et électrodynamiques passifs, exempts de lubrification. L'équipement n'utilise pas de joints mécaniques puisque le rotor est placé à l'intérieur du confinement de pression du gaz. L'équipement ne requiert pas de systèmes auxiliaires pour le refroidissement, la filtration, la séparation ou l'alimentation en fluides lubrifiants.
