Science Acadmy of Hebei Province Agriculture and Forestry, Shijiazhuang 050011, China)Abstract: In the resent years, the APPI (Agricultural Products Processing Industry) of Hebei has developed rapidly However, generally speaking, the agricultural industry chains are short. The extent of refined processing and finish machining is low. The scales of most enterprises are small The processing technology and equipments are backward In this paper, the present situation of Hebei APPM (Agricultural Products Processing Mechanization) is introduced Then the situation of Hebei APPM faced and main problems is made clear Thus, the suggestions and countermeasures of Hebei APPM development are put forwardKey words: agricultural engineering; agricultural products processing; summary； mechanization; development countermeasures196 ,2003:36-38.Design Model of 3D Twisted Blade of CentriMl.:fugal PumpC.

Xihua University, Chengdu 610039, China)Abstract: The double-suction centrifugal pumps with distorted blade have complicated blade shape and multiflow channels characteristics There are a lot of problems involved in 3dimensional modeling of double-suction centrifugal pumps which are common in 3dimensional modeling of pumps In this paper we utilize a concrete modeling example of the double-suction centrifugal pumps to introduce a method of 3dimensional 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 3dimensional 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 structuresKey words: power and machinery engineering; doublesuction centrifugal pump; design; distorted blade; spirality turbines casing; three- dimensional modeling; Gambit222© 1994-2010 China Academic Journal Electronic Publishing House.
