恒压供水PLC控制系统设计与实现

Design and Realization of Constant Pressure Water Supply System Based on PLC

恒压供水系统是采用变频调速技术和PLC技术实现自动给水的机电一体化供水系统。该控制系统以供水压力为控制对象,通过PLC控制变频器,进而控制水泵机组转速,达到恒压供水的目的,实现了预期的设计要求。

In this paper,a constant pressure water supply system is designed,which is based on frequency conversion technology and PLC technology.The water pressure of water supply control system is taken as the control object,the inverter is controlled by PLC,then it controls the water pump to achieve constant pressure water supply,and the desired design requirements is met.
