Centrifugal compressor impeller for pressure ratio over 1.79 - maximises flow by choosing relative blade thickness between specified limits |
| 摘要 |
<p>The impeller (1) is intended for a centrifugal compressor whose ratio of maximum pressure at no flow (Pmax) to intake pressure (P1) equals or exceeds 1.79. The blade (2) thickness is selected such that the ratio (tan) of the volume between two adjacent blades (V2) to the total volume of Vz plus the volume of one blade (Vs) lies between a maximum value of 0.72 and a lower value defined according to a specified formula.</p> |
