Subject Content and Scope of Application
HG/T 2123-91
20010326
This standard specifies the types, series and main parameters of agitators. This standard applies to agitators installed in vertical mechanical stirring vessels with a nominal diameter of 400~5800mm, which are used for stirring liquid media with a density of less than 2000kg/m3 for various physical and chemical processes. 2 Symbols
DJ: agitator diameter;
DN: inner diameter of the stirring vessel;
b: agitator width:
bh: Height of agitator from the bottom
: Blade length:
d: Impeller diameter:
h: Blade height;
S: Pitch of ribbon agitator or screw agitator; h: Height of guide tube;
Da: Inner diameter of guide tube;
Z: Number of blades;
0: Blade inclination angle;
2: Blade bend angle;
β: Blade upward angle:
Zt Number of ribbons.
