摘　　要：针对传统掘进机外接冷却水的冷却方式应用受限的问题,提出一种掘进机温度自动控制系统设计方案。该系统采用风冷却器作为强制散热单元,采用PLC作为控制单元,通过温度信号采集及处理、PID控制等,使掘进机截割电动机和液压系统温度保持在允许范围内。井下工业性试验结果表明,在掘进机没有外接冷却水的情况下,该系统有助于掘进机长时间稳定运行。For limited application problem of traditional roadheader cooling methods by external cooling water, a design scheme of automatic temperature control system for roadheader was proposed. The system uses air cooler as a mandatory cooling unit and PLC as a control unit, and can make temperatures of roadheader cutting motor and hydraulic system within allowable range through temperature signal acquisition and processing and PID control. Underground industrial test result shows that the system helps roadheader run long and stably without external cooling water.
