why design this configuration ?
why design this configuration ?
(OP)
I saw a structure drawing of single stage centrifugal pump. From the suction flange to intake of impeller there is a cone-shaped pipe structure.It means the intake is more and more small diameter.who know why use this structure ? how did it work? Is there any advantage for NPSH or others ?

It is possible that the impeller eye is "X" diameter -- but the pump inlet flange is sized to suit a particular pipe size, therefore the best configuration is to have a conical inlet to the impeller eye.
For example - the impeller eye might be 160mm diameter, the next pipe diameter is 200mm nominal bore, therefore you would expect a 200mm inlet flange.
I doubt if it has anything to do with NPSH design.

Not sure if your post was in response to my earlier posting, if it is, I am happy to rephrase and clarify my thoughts.
