  • Impeller of centrifugal compressor
    Patent number: 4863349
    Abstract: The invention relates to compressor manufacture. The impeller comprises a base disc (1) wherein, according to the invention, the angle (.beta.) between its internal surface (5) and the plane (p) perpendicular to the impeller rotation axis (0--0) is 0.5-1.degree. larger than the angle (.alpha.) between its external surface (4) and the same plane (p).

  • Centrifugal compressor impeller
    Patent number: 4795311
    Abstract: An impeller, comprising a main disc (1), blades (2) and a covering disc (3) which consists of interconnected web (4) and ring (5). The joint of the web (4) and ring (5) is detachable to form mated surface (6 and 7) in the place of the joint and has on the surface (7) of the ring (5) an annular shoulder (8) and on the surface (6) of the web (4) an annular groove (9) accomodating the shoulder (8). The internal diameter Do of the web (4) is less than the diameter (D) of the ring (5) along their mated surfaces (6 and 7) by 1 to 1.5.times.10.sup.-3 Do.

  • Method of regulating multistage axial compressor output and an axial compressor for carrying same into effect
    Patent number: 4147473
    Abstract: A method of regulating the output of a multistage axial compressor having two coaxial rotors in series. The regulation of the compressor output is effected by varying the head of the medium to be compressed, the variation of the head of the medium being effected, after the medium leaves the stator, by changing the rotational speed of the first rotor, the speed of the second rotor being kept constant. The first rotor is connected to a variable-speed drive motor and the second rotor is connected to a constant-speed drive motor.
