Prediction and Calculation of Vacuum Pump Pumping Speed Curve Based on MATLAB/GUI
Based on the geometrical characteristics of screw vacuum pump rotor and the internal leakage model of screw vacuum pump,a mathematical model of the internal working process of the screw vacuum pump is established.With the help of MATLAB software,the fourth-order Runge-Kutta method is used to solve each differential equation as the initial condition repeatedly,and an application program that can quickly calculate the pumping speed curve of the screw vacuum pump is designed according to the MATLAB/GUI interface.The program is used to predict and calculate the pumping speed curve of a variety of screw vacuum pumps,and it is improved according to the results of the examples.
