to investigate the effect of the impeller blade
angle and its shape on regenerative pump performance.
Traditional centrifugal compressors with design capacities of 967kW (275 ton) and less also begin to suffer a degradation of full load efficiency due to the smaller impeller blade
spacing which increases the flow friction losses (Stoecker and Jones 1982).

Our attention is focused on the effects of impeller rotational speed, fluid rheology and impeller blade
The shroud has its inner contour shape in such a way to match the impeller blade
tip from the inlet to the exit of the impeller.
The distance from the surface of the liquid to the centreline of the impeller (submergence, S) was varied from the impeller blade
height to half of the total liquid depth (0.
Beyond that, the leaching of iron can cause impeller blade
failure and possibly leaks in the solder pot, forming a machine safety issue.
pitch adjustment can be carried out while still attached to the fan's drive shaft, the company said.
These cavities are usually formed on the impeller blade
suction surface .
Values of the impeller blade
height and width are b= D / 5, a = D / 4 respectively.
Larger radial gaps between the impeller and housing result in flow reversal at the impeller blade
tips and reduced pumping efficiency.
The gun's large impeller blade
provides for a large total air volume across the heating element, 285 liters/min.
