[Abstract]:As a common hydraulic machinery, centrifugal pump is widely used in water supply and drainage, agricultural engineering, industrial engineering, aerospace, navigation engineering and energy engineering. Impeller is the core component of centrifugal pump, its design speed and quality directly affect the product R & D cycle and market competitiveness. On the basis of understanding the application of impeller CAD at home and abroad, aiming at the deficiency of the current research and application of impeller CAD, this paper takes Pro/E as the supporting software and the object-oriented Visual C 6.0 programming language as the development tool. The parametric programming of impeller is realized by using Pro/TOOLKIT, which combines 3D impeller model with program control. The research contents of this paper are as follows: 1. On the basis of univariate and three-dimensional flow, the empirical formulas for calculating the parameters of centrifugal pump and impeller are given, which provides convenience for the design of the parameters of the later model. In view of the complicated design procedure of traditional centrifugal pump, the method of designing axial streamline of impeller by 4 times Bezier curve is put forward, and the control method of axial streamline line is introduced in detail. The axial section line and woodblock diagram of blade are drawn in detail. The general expression of flow line of impeller blade of centrifugal pump is constructed by using NURBS curve. Based on the principle of parameterized design, the automatic generation scheme of 3D model of impeller of centrifugal pump is established. The realization method of centrifugal impeller 3D modeling based on Pro/TOOLKIT is described. 4. In VC programming environment, the impeller model is developed by using Pro/TOOLKIT toolkit and model-based method, and the parametric design of impeller is realized. The kinematics analysis and simulation of centrifugal pump impeller are carried out by using Mechanism kinematics analysis module of Pro/E. The position, velocity and acceleration curve of impeller motion are obtained and analyzed.
