Definitions

  • WO-A-96/22835 also discloses a complex canister structure for improved separation efficiency involving, inter alia, such outwardly radial flow of newly injected liquid by way of an array of channels defined between radially extending strengthening ribs in the chamber end wall, or equivalent radially extending ribs adjacent said wall, including a cone stack which overlies the inlet channels between said ribs or equivalent at the end wall so the liquid cannot follow a short circuit path and must flow radially outwardly for the desired radial length of the channels.
  • the cone stack also includes radially extending ribs which react with liquid returning from the outer peripheral wall in a radially inward direction to translate some of the centrifugal energy thereof into rotational energy of the rotor.
  • outer regions of the axial discontinuities may, however, in the alternative be displaced circumferentially in a direction that is leading with respect to the rotation direction of the rotor that results from ejection of liquid.
  • the upper end wall 23, that is the end wall opposite to the outflow chamber, has at its internal surface 23 s an array of axial discontinuities 40 1 , 40 2 ... formed as embossments pressed at the time of drawing the contained wall to shape, and in particular comprise ribs, raised with respect to the internal surface 23 s of the wall, of relatively narrow cross-section and smooth contour side-to-side, within the constraints of being pressed unidirectionally with drawing of the container wall.
  • the ribs extend between the radially inner and outer edges of the end wall, as defined by the junction with the peripheral side wall 22 and bearing tube 25, the ribs having not only a radial component of direction but also a circumferential component as a smooth and consistent curvature along their entire lengths such that at their radially outer regions they are displaced circumferentially with respect to regions inwardly thereof in a direction that is trailing with respect to the rotation direction of the rotor canister that results from ejection of liquid lubricant from the container.
  • the radially outer regions are displaced with respect to the radially inner regions in the same circumferential direction as liquid is ejected from the outflow chamber by way of the reaction nozzles.
  • FIGS 9(a) to 9(c) these are generally similar to the views of Figures 1(a) to 1(c) but of a further embodiment of centrifugal separator 200 including a ninth embodiment of rotor canister 220.
  • Those parts of the separator housing which correspond to those described above with reference to Figure 1(a) are given like references and not described further.
  • the rotor canister 220 likewise has many parts identical with rotor canister 20 and like references are again used and detailed description omitted. Where the rotor canister does differ is that the axial displacements, in the form of embossed ribs 240 1 , 240 2 , 240 3 ... have their radially outer regions circumferentially displaced in a direction that is leading, or forward, with respect to the clockwise rotation direction of the canister that results from ejection of the liquid from the outflow chamber.
  • the axial displacements have been at the upper end wall of the rotor canister separation chamber, and opposite to the outflow chamber at the lower end of the canister, it will be appreciated that if the rotor is designed such that liquid is ejected from an outflow chamber at the operationally upper end of the rotor then the separation chamber inlet apertures will be moved to the lower end wall of the canister and the axial displacements formed at such lower end wall.
