混流式脱硫泵参数化三维建模及磨损特性分析
|
摘要
本论文以内蒙古金桥电厂脱硫泵为研究对象,阐述应用面向对象的编程语言Visual Basic开发SolidWorks的原理和方法,系统介绍三维实体造型软件SolidWorks的二次开发方法。结合混流式浆液泵的水力设计方法,通过数据库将设计参数进行关联设计,通过SolidWorks软件采用从点到线、从线到曲面、再从曲面到实体的构型方法,自动生成混流式浆液泵叶轮和蜗壳的三维实体模型,为后续的流场数值模拟奠定基础,然后利用数值计算流体力学软件FLUENT对脱硫泵内部流场固液两相三维流动进行数值模拟,初步揭示脱硫浆液泵流道内固液两相的速度场分布、压力场分布以及颗粒运动规律,以期为更好地设计脱硫泵,减少磨损以及延长脱硫泵的使用寿命提供一些参考依据。
Taking the study of inner Mongolia Jinqiao power plant desulfurization pumps, this thesis described the principles and methods that the object-oriented programming language Visual Basic further develop SolidWorks, systematically illuminate the further development approach of 3D solid modeling software—SolidWorks.Combining with mixed-type slurry pump hydraulic design methods, the mixed-type slurry pump impeller and volute 3D solid model was automatically generated by parameter design methods through the database and by the use of SolidWorks software(from point to a line, a line to the surface, from surface to the entity's configuration method). Then the solid-liquid two phase flow field of desulfurization slurry pump was simulated by CFD software FLUENT6.2.The law of particle velocity distribution, pressure distribution and abrasion characteristics on different conditions of diameter and concentration of solid particles was initially revealed. The aim of this paper is to provide several references for designing better desulphurization pump, reducing erosion and extending the life of desulphurization pump.
