Which one has more severe cavitation, an axial flow pump or a centrifugal pump? I don’t quite understand it; I’m seeking help from the experts here.
The question can’t be asked that way. It is recommended that you first understand the required net positive suction head and the effective net positive suction head.
I think it’s sufficient to check the pressure difference between the inlet and outlet of the pump. Cavitation is severe at high pressure differences. It’s not about the type of pump
It’s no longer in the form of a pump, but rather relates to your operation and maintenance
Centrifugal pumps generally provide the required NPSHr value, which is used to determine the suction lift. For diagonal-flow pumps, mixed-flow pumps, and axial-flow pumps, requirements regarding the submersion depth S are generally specified; this is to ensure that the operation of these pumps is not affected by eddies. Under normal circumstances, S is greater than NPSHr. Therefore, manufacturers of axial-flow pumps provide only the minimum submersion depth S value in their catalogs, without giving the NPSHr value.
