摘要
介绍了用ＰＬＣ控制的变频调速恒压供水系统，阐述了系统的构成，用ＰＬＣ和变频器实现了对多台泵、阀的逻辑控制及变频泵的速度控制，并给出了ＰＬＣ控制的程序流程图．本系统经实际运行证明：可靠性高，抗干扰能力强．
The paper introduces the variable frequency speed control system of constant pressure water supply device with PLC.It explains the structure of the system,which by using PLC and inverters performs logical control of pumps,valves and the speed adjust of the variable frequecy pumps.The flow diagram of PLC is also given,High reliability and disturb-resistance has proved by its applied result.
