摘要
简要介绍了用单级调速装置实现的恒压供水系统，讨论了用PLC实现双闭环串调压力控制的方法及软件结构．
This paper briefly passes on the constant pressure supply-water system reali/ed by series SR system, discusses the double-close-loop series regulation pressure control in PLC and the software structure, and emphatically inquires Into the method or the relay control system transformed by PLC.
