摘要:
通过对工业现场消防管网稳压控制过程进行研究，选择PLC为控制核心,设计和开发其控制系统。该系统利用可编程逻辑控制器控制2台稳压泵定时切换，压力调节器可根据检测到的管网压力变化控制变频器自动调节消防稳压泵的转速，使消防水的压力保持在基本恒定状态，从而满足消防用水的流量需求。该控制系统可通过调节压力调节器的设定值，满足不同消防管网压力的要求，同时具有完善的电气安全保护措施，对一些常见故障可实现自行诊断并报警。
Abstract:
Based on the study of the control process of the pressure stabilization of the fire pipe network in the industrial field, PLC is selected as the control core, and its control system is designed and developed.The system uses programmable logic controller to control the timing switching of two stabilized pressure pumps. The pressure regulator can control the frequency converter to automatically adjust the rotation speed of the stabilized pressure pump according to the detected pressure change of the pipe network, so as to keep the pressure of the fire water in a basically constant state, so as to meet the flow demand of the fire water.The control system can meet the requirements of different fire pipe network pressure by adjusting the set value of pressure regulator.At the same time,it has perfect electrical safety protection measures,which can realize self diagnosis and alarm for some common faults.
