| 摘 要： | 该双恒压供水控制系统是以PLC控制为核心,变频调速技术为基础,并结合压力传感器、变频器、水泵、继电器、接触器等组成。在此系统中,PLC将压力设定值与测量值的偏差经PID运算后得到的控制量作用到变频器,从而通过变频器控制水泵的转速调节管网的压力,实现恒压供水的目的。

| Abstract: | This water supply system under constant pressure designs a suit of PLC controlling system based on variable frequency speed-regulating technology. The system consists of pressure sensors, transducer, pumps, relays, contacts device and so on. In this system, by comparing the setting value and measuring value of pressure, the deviation is obtained. Then the control volume is obtained by the PID operation to affect the transducer. Thus the pump rotational speed is controlled through transducer to adjust the pressure of the pipe network and realize the constant pressure water supply goal. |
