Abstract
881,882. Centrifugal pumps and compressors. SULZER FRERES S.A. Dec. 8, 1958 [Dec. 23, 1957], No. 39514/58. Class 110 (1). A centrifugal pump or compressor comprises a first ring 4 concentric with the rotor shaft and forming a part of one of the walls of the diffuser of the pump or compressor, the flow cross-section of the diffuser being adjustable by varying the distance S between the diffuser walls by axial movement of the first ring 4, a second ring 13 concentric with but axially spaced from the ring 4 and restrained from axial movement, and at least three motiontransmitting members 12 extending between the two rings and arranged at the same angle of akew α in relation to the rotorshaft, the rings 4, 13 being relatively rotatable and the members 12 being arranged to convert relative rotation of the rings into axial movement of the first ring 4. As shown, the ring 4 is held against push members 11 and the members 12 by a spring 10 and the excess of the pressure between the diffuser walls over that behind the ring 4. Each motion-transmitting member 12 has two spherical ends, one located in a guide passage 14, and the other in a recess 16 in the ring 13. A space 19 containing the motion-transmitting members 12 is sealed off from the diffuser by metal bellows or other sealing members 20 and the first ring 4 has a sealing ring 7. The second ring 13 is rotated by a worm 17 engaging a toothed segment 18 and rotation of the ring will displace the members 12 as in the upper diagram of Fig. 2, which shows the mechanism with the skew angle α at a maximum. The arrangement described compensates for the increasing percentage reduction in flow cross-section for a given movement of the ring 4 as the distance between the walls decreases. An adjusting screw 22 may be provided for adjusting the effective length of the member 12.
