Abstract
PURPOSE: To increase the strength of a vane without increasing the weight of the vane by increasing the weight of the vane top edge side of the open-type impeller of a mixed flow pump.
CONSTITUTION: A vane wheel 1 is provided with a plurality of vanes 2 and supported by a rotary shaft 3 and revolved in the X direction. The weight of the top edge 2a side of each vane 2 is made larger than the weight of the root 2b side. Namely, the thickness W of the vane 2 is increased gradually from he root 2b towards the top edge 2a. The rate of increase is set so that the thickness W1 of the top edge part 2a is 105%W150% of the thickness W2 of the root part 2b. As the weight of the top edge 2a side at high speed part increases, the centrifugal force F which acts onto the vane 2 increases. The differential pressure P which acts perpendicularly to the vane 2 and the orthogonal component F' for the vane 2 of the centrifugal force F are balanced, and a large stress does not act onto the root 2b part.
