Maybe discharge cavitation is not a correct term.
I meant the formation of recirculation flow in the gap area and the effect of such a (strong?) flow on the impeller/casing surfaces.
Thanks for your explanations.
Thanks Artisi
It is not a real or practical subject, just I was studying about it.
I was thinking if we decrease the gap, will it affect the recirculation flow in the zone between the impeller and the casing that in turn results in higher/lower discharge cavitation?
thanks all
The picture is schematic and I do not have the full picture.
So if I understood correctly, less gap=higher Q = More efficiency due to less hydraulic loss...
The drawing is for a closed, double suction impeller.
However, I am asking generally...i.e., what is the the effect of gap on hydraulic of an open/semi-open or closed impeller...
Hi all
I have a question...if we replace an existing impeller with a wider one, then the side gap between the impeller and the casing decreases (from w1 to w2, see the attached picture). what is the effect of this reduction in the gap size on the hydraulic of the pump?...assume that all the...
Hi everybody
I would be thankful if you let me know your viewpoint about the following
Today at a pump factory I saw a pump that had vanes with triangle cut. i.e., instead of having common straight/oblique cut it had a forward tringle shape. see the attached file where the red lines show the...
