IMPELLER FOR CENTRIFUGAL COMPRESSOR |
摘要 |
<p>Providing an impeller of a centrifugal compressor wherein the interference of the leakage vortex flow generated at the tip end side of the full blade with the leading edge of the splitter blade can be evaded and the high pressure ratio and the enhanced efficiency can be achieved. An impeller wherein a throat SR is formed so that a distance from a leading edge 5a of a rear side full blade 5R located on the rear side of the rotation direction of the compressor to a front side full blade 5F adjacent to the rear side full blade 5R and located on the front side of the rotation direction is minimized, and the leading edge of the splitter blade is placed in a fluid flow streaming along the flow passage between the mutually adjacent full blades, on the downstream side of a leakage vortex line WL formed to connect the middle location P of the throat to the leading edge 7a of the front side full blade 7.</p> |
