对《SPWM变频调速应用技术》中关于恒压供水主体方案讨论的商榷

Discussions on the Major Scheme for Water Supply under Constant Pressure In SPWM Frequenly Conversion Speed Applied Technology

自动化新技术丛书《SPWM变频调速应用技术》(张延滨编著)是一本非常好的书,但书中关于恒压供水主体方案的讨论一节的观点有待商榷,本文对恒压供水主体方案的确定举例进行了分析,并提出恒压供水主体方案确定应考虑系统的运行方式,经综合比较分析最终确定合理的方案。

SPWM Frequenly conversion speed Applied Technoogy written by Zhang Yanbin, an automation new technology series, is a very good book, but the ideas about the discussion of major scheme for water supply under constant pressure is worth re-discussing in this book. In this paper, the fixed example of the major scheme for water supply under constant pressure is analyzed. Then the system's running method is put forward when establishing the major scheme for water supply under constant pressure, and the reasonable design is finally set up through comprehensive analysis.
