THICK BLADE CENTRIFUGAL VANE WHEEL

THICK BLADE CENTRIFUGAL VANE WHEEL

A thick blade centrifugal vane wheel is composed of at least two baldes, the thickness of which is increased to such degree that the blocking function Kr) satisfies following conditions: the radius r must be greater than or equal to r1 and less than or equal to 0.8 (r2-r1) +r1 and r2/r1 must be larg...

Zusammenfassung:A thick blade centrifugal vane wheel is composed of at least two baldes, the thickness of which is increased to such degree that the blocking function Kr) satisfies following conditions: the radius r must be greater than or equal to r1 and less than or equal to 0.8 (r2-r1) +r1 and r2/r1 must be larger than 1.7, at first half of the flow channel must be greater than or qequal to r1 and less than or equal to rm where r1, r2 and rm are the radii of front fringe, rear fringe and average radius of the blade respectively. Said invention can decrease or eliminate the flowing separation region and the recurrent region neighbouring the pressure surface of the blades, thus increasing the efficiency significantly.
