  • Centrifugal compressors and related compressor devices often use a diffuser assembly to convert kinetic energy of a working fluid into static pressure.

  • An example of the diffuser assembly arranges several diffuser vanes circumferentially about an impeller.
  • the design e.g., shapes and sizes
  • the design in combination with the orientation of the leading edge and the trailing edge of the diffuser vanes with respect to the flow of the working fluid, can determine how the diffuser vanes affix within the diffuser assembly.
  • the diffuser assembly incorporates variable diffuser vanes, which can move (e.g. rotate) during operation of the compressor device.
  • This degree-of- freedom improves the design and flexibility of the compressor device to adapt to working conditions, e.g., changes in flow rate of the working fluid.
  • the variable diffuser vanes can move to change the orientation of the leading edge and the trailing edge to tune operation of the compressor device.
  • Known designs for variable diffuser vanes rotate about an axis that resides in the lower half of the diffuser vanes, i.e., closer to the leading edge than the trailing edge.
  • This disclosure presents embodiments of systems and methods that can modify orientation of variable diffuser vanes to improve performance of a centrifugal compressor and related compressor devices.
  • the embodiments manage the position of the diffuser vanes relative to operating characteristics associated with the diffuser assembly.
  • a controller couples with an actuator to collect data that relates to operation of the actuator to position the diffuser vane during operation of the compressor device.
  • the data can reflect, for example, input power the actuator requires to move the diffuser vanes between a first position and a second position.
  • the controller can compare the data to identify the change in the operating characteristics that occurs, if at all, when the diffuser vanes move between the first position and the second position.
  • the controller can generate an output in response to changes in the operating characteristic to move the diffuser vane to a third position.
  • the controller can collect data about the operating characteristic at this third position and, subsequently, use the data to identify any change in operation of the actuator with the diffuser vanes in the third position. For example, pressure the working fluid imparts on the diffuser vanes in the third position may balance across the diffuser vanes, thus reducing the input power that the actuator requires to maintain the diffuser vanes in the third position. This reduction in input power can indicate that the diffuser vanes are in an optimal position for operation of the compressor devices.
  • the process of moving the diffuser vanes among positions continues to optimize performance of the compressor device, e.g., to reduce power consumption and to achieve and maintain peak compressor efficiency within the entire operating envelope for the compressor device.

  • these embodiments use feedback from an actuator that couples with the diffuser vanes.
  • the feedback can embody, for example, an input (e.g., a digital signal, an analog signal, etc.) that describes an operating characteristics of the actuator.
  • the embodiments can use this operating characteristic to instruct the actuator to move and, in turn, manipulate the position of the diffuser vanes, thereby reducing power consumption of the compressor device.
  • the operating characteristic for the actuator can help to achieve and maintain peak efficiency within the entire operating envelope of the compressor device.
  • movement of the actuator can modify the orientation of the diffuser vanes, e.g., relative to the flow of a working fluid in the compressor device.
  • the operating characteristics may, for example, reflect the input power (or other measure) that the actuator requires to perform this movement and/or to maintain the diffuser vane in a specified position relative to the flow of the working fluid.
  • the input power may vary; typically in response to the change in the orientation of the diffuser vane relative to the flow of the working fluid.
  • the diffuser vanes may assume a position in which the pressure of the working fluid balances about the surfaces of the diffuser vanes. In this position, the input power may have its lowest and/or smallest value, e.g., thus reflecting that the balancing of pressure of the working fluid and that the compressor devices is operating at peak (or near-peak) efficiency.

Abstract

Des modes de réalisation se rapportent à un système et à un procédé pouvant modifier la position d'aubes de diffuseur afin d'améliorer les performances d'un dispositif de compression, par exemple un compresseur centrifuge. Ces modes de réalisation comprennent une boucle de rétroaction pour gérer la position des aubes de diffuseur par rapport à une ou plusieurs caractéristiques de fonctionnement d'un actionneur qui transmet un déplacement aux aubes de diffuseur. Selon un mode de réalisation, le système et le procédé mesurent la caractéristique de fonctionnement pour l'actionneur avec les aubes de diffuseur dans une première position et dans une seconde position. Le système peut comparer des valeurs pour les caractéristiques de fonctionnement, des changements apportés à la caractéristique de fonctionnement pouvant identifier d'autres positions des aubes de diffuseur afin de réduire la puissance d'entrée que l'actionneur consomme pour déplacer et/ou maintenir la position des aubes de diffuseur. Cette propriété peut se corréler avec des performances optimales du dispositif de compression et avec une efficacité de compression optimale dans toute l'enveloppe de fonctionnement du dispositif de compression.
