Research On The CAD System And Three-dimensional Entity Model Of Centrifugal Pump

Along with the quick development of computer technology, the edition of operating system of Windows2000&XP or higher level appears in succession , makes the original CAD software based on the centrifugal pump of DOS or Windows95&98 in the aspect of systematic compatibility, the reliability of normal operation and the upgrading maintenance of software not to adopt. So, the more and more CAD software users of centrifugal pump hope to develop a set of operating more simple, professional software that is easy to escalate and can run on Windows high edition. This paper is absorbing forefathers experience and analyses its insufficient foundation, with software project method as guiding ideology, have established the new impeller CAD system of centrifugal pump that can expand and open in Windows environmental, have developed a set of apply to low , neutralization the impeller CAD program of specific speed of centrifugal pump, and on this foundation, have painted this system and the three-dimensional entity model of impeller .The system, with VC6.0 that is object oriented programming language is development platform and ObjectARX2000 is development language, AutoCAD2002 and MDT is graph support software, has adopted data communication technology , seeks a complete impeller CAD course of centrifugal pump of generation consummately from the basically parameter input and calculation of centrifugal pump to impeller wooden mould picture, part drawing and three-dimensional entity. Here Aimed at the lack of the current software, used VC6.0 as the development base, ObjectARX 2000 as the development language, AutoCAD 2002 and MDT as the drawing supporting software,make whole procedure convenience, and convenient for maintenance, improvement and promote to higher grade. Through establishing the three-dimensional entity model of centrifugal pump, include target function, and finally used complex method to realize parameters optimal design, and make the result more reasonable. The major work of this paper is: 1.this paper uses space freely curve convection road center line according to the excellent hydraulic model of appendix part of 《modern pump design manual 》, throughthe way that derives , draft to suit. 2.Adopt object oriented programming language ,draw support from the basic storehouse and powerful editor function of VC++ , strengthen the adaptability of software ,and improves maintenance , in order to raise human-computer interaction ability. 3. Have drawn up program to carry out the hydraulic design of impeller and paint type, reach three-dimensional entity model, part drawing and the wooden mould picture of impeller. 4. The AutoCAD drawing model-place is executed in the circumstance of VC6.0 and ObjectARX 2000 , and the parametrically drawing and modeling areunder the control of a friendly User Interface, which is realized by using VC programs. 5. Have established the new impeller CAD system of centrifugal pump that can expand and open in Windows environmental, have developed a set of apply to low , neutralization the impeller CAD program of specific speed of centrifugal pump, and on this foundation, have painted this system and the three-dimensional entity model of impeller . 6. With VC6.0 that is object oriented programming language is development platform and ObjectARX2000 is development language, AutoCAD2002 and MDT is graph support...
