Static imbalance of centrifugal pump impeller
Thread Content
When checking for static imbalance in a centrifugal pump impeller, let the impeller rotate freely; if, once it reaches stability, a certain point remains at the lowest position at all times, then that point is the location of the imbalance. Right or wrong, why
Yes, basically it’s viewed that way – rotate it a few more times and then look at the stopping point
That’s right; if the pump impeller is always tilted slightly downward, that’s the point of imbalance
Finally, look up specialized data on static balance – details are still very important
