Centrifugal pump impeller blade number of head and flow have what relation, usually for a few pieces, why have a lot of, and some only 5-6 pieces
The number of slices is calculated according to the performance of the pump, the number of pieces is mainly to maintain the stability of the flow field, as little as possible vortex, which can improve efficiency. In the same size of the impeller conditions, the number of chips and head related, and flow is not much. Learn more about the textbook "pump and fan". Before you read, you'd better look at the engineering fluid mechanics first".
As can be seen, the multi-stage pump head and impeller number is proportional to the flow unchanged. Like 2 stage impeller, equivalent to 2 pumps in series, the flow is inconvenient, the head would like to add. Impeller height you say, the main parameter should be the impeller exit width, the greater the width of the outlet, the greater the flow. It has nothing to do with the lift.
