Model of Double-suction Centrifugal Pumps with Distorted Blade

The double-suction centrifugal pumps with distorted blade have complicated blade shape and multi- flow channels characteristics. There are a lot of problems involved in 3-dimensional modeling of double-suction centrifugal pumps which are common in 3-dimensional modeling of pumps. In this paper we utilize a concrete modeling example of the double-suction centrifugal pumps to introduce a method of 3-dimensional modeling about distorted blade of impeller and spirality turbines casing of centrifugal pumps based on the Gambit software. And it introduces the detailed processes of creating solid model and drawings of 3-dimensional modeling. Moreover, some problems need to be concerned relating with the modeling in Gambit software are briefly mentioned. The modeling result shows that, this method is convenient. It can reflect the characteristic of the flow field structures.
