The Design And Implementation Of Centrifugal Pump Hydraulic Model Database System

This paper focuses on research the centrifugal pump type selection database managemethod at home and aboard,and analyzes selection system via internet.The research of thispaper had followed a detailed analysis of the actual demand,and the specific contents of myresearch as follows:（1）This system based on consumer demand in develop process.All parts of it,such ashome page information,company and products introduction,client information management,centrifugal pump information selection system are built from system database andinternet-sharing technology. Take advantage of internet convenience for this system database.（2）The contents describe centrifugal pump selection principle and guidance andconfirm the centrifugal pump characterize curve by mathematical analysis.All of operatingpoints are defined by second-degree parabola,it also means that we use function curveformulas and instrument system curve formulas for slove. Second-degree parabola analysis isthe best way for curve fitting.（3）The system uses a structured analysis method. The system of needs to be analysedas the system of centrifugal pump selection principles and basis,set up the platform,systemdevelopment and application of technology,software development ideas,architecture,processanalysis,data dictionary and database for the overall design and detailed design. Should followthe principles and coding,testing and maintenance,software development of key technologyand the realization of the system operating environment will be described.
