Definitions

  • Such compressors when the working fluid is wet, some liquid accumulates inside the casing of the compressor during operation. The accumulated liquid must be drained outside the casing. Therefore, such compressors must have an external drainage system, i.e. a system for external drainage.
  • the compressor 200 has an annular cavity 256 designed for electrical distribution of power and control of the bearing device 250.
