煤矿强排自动控制系统设计

摘要

设计了适用于煤矿井下并可在地面控制室对潜水泵等设备进行集中监测和控制的强排自动控制系统.该系统以可编程控制技术为核心,通过各种矿用本质安全型传感器实时监测潜水泵现场的水仓水位、出水口压力、潜水泵的温度等参数,通过对潜水电动液控闸阀的操作实现强排系统的自动控制.现场工业性试验结果表明,该系统运行情况良好,PLC控制稳定.%Automatic control system of forced drainage was designed which was applicable to coal mine and can achieve monitoring and control of submersible pumps in a ground control room.The system takes programmable control technology as core,uses a variety of mine intrinsically safe sensors to real-timely monitor parameters such as water level,outlet pressure and submersible pump temperature,and realizes automatic control of forced drainage system through operation of diving electro hydraulic gate valve.The field industrial test results show that the system is running well and the PLC controls stably.
