The blade is deciding factor of centrifugal pump head high and low
一 relationship with leaf outlet setting angle β2A
When the other are setting values, blade outlet angle is larger, with the increase of flow theory head also increases accordingly, leaf outlet setting angle is smaller, along with the increase of flow, theoretical head corresponding decrease.
二 relation with leaf numbers
When others are setting value, not consider flow loss situation, leaf number is more, theoretical head is bigger. This is due to limited vane impeller can give liquid energy is infinite vane impeller decreased.
三 relation with rotate speed
By euler equations can be concluded that the higher the speed, the greater the theoretical head.
