  • Patent number: 10352188
    Abstract: The present disclosure is relates to a centrifugal turbo machine equipped with stretchable and variable diffuser vanes capable of securing further improvement of compression efficiency by reducing an angle of the vane and increasing a length of the vane using forced rotating driving of a diffuser during operation of a compressor so as to reduce frictional loss of the fluid when a flow rate of fluid is reduced.

  • Publication number: 20020094267
    Abstract: An instability detecting device, used for easily and simply detecting a rotating stall and/or a surge frequently occurring during an operation of a turbo compressor, is disclosed. The detecting device of this invention has a detector (20) consisting of a body (22). First and second pressure tubes (25) and (26) are axially set in the body (22) while parallely extending on the same plane, with first and second pressure discharge ports (25a) and (26a) of the first and second pressure tubes exposed to the outside of the body (22) at an end surface of the body (22). A partition wall (28) is arranged on the end surface of the body (22) while crossing the end surface and separating the first and second pressure discharge ports (25a) and (26a) from each other.
