How to eliminate curve humps
Thread Content
After testing the ZA50-315 pump, there is a slight hump on the curve; what measures can be taken to eliminate this hump?
It is better to let the manufacturer make local adjustments to the geometric parameters of the impeller using tools or software such as hydraulic models.
Yes, I’ve read some of Mou Jiegang’s papers online; this situation is related to many parameters related to the hydraulic dimensions, and there is no one-size-fits-all solution. I plan to first add a baffle at the inlet to reduce the pre-rotation of the liquid flow there and see what the effect is
My personal advice is to start with the peripheral components first; if those don’t work, then move on to the equipment, and be cautious when doing that :)
What exactly does the periphery refer to? Please explain in detail
