离心泵变频调速后轴可靠性设计及CAD

Reliability Design and CAD of Centrifugal Pump Axes after Frequency Conversion and Timing

针对在离心泵改造中变频调速后轴强度和临界转速设计准则的改变,对变频调速后轴的可靠性设计进行分析,并用面向对象方法和数据库技术开发离心泵变频调速后轴的强度校核和临界转速校验的计算机辅助设计交互系统.给离心泵变频调速后轴的可靠性设计提供了一种便利有效的工具.

In view of transforms of intensity and critical rotation speeds design criterion of axes after frequency conversion and timing of centrifugal pump, the reliability design of the axes are analyzed,and a CAD alternate system is developed to examine the intensity examination and verify the critical rotation speeds for the axle after frequency conversion and timing of centrifugal pump by the object - oriented method and database technology. The system offers a convenient and effective tool for reliability design
