摘　　要：在详细分析冷却塔风机传动系统中齿轮箱、传动轴失效原因及其失效表现形式的基础上,设计出冷却塔风机齿轮箱及传动轴故障监控系统,利用可编程控制器对齿轮箱油液温度、振动和传动轴信号进行采集处理,利用特定程序,能够在齿轮箱及传动轴发生失效现象之前及时报警停机,避免安全事故的发生,此系统与冷却塔风机智能控制系统相结合,可以实现冷却塔风机的智能变频与启停、故障预警与停机。Based on the detailed analysis of failure cause and form of gear box and transmission shaft in the cooling tower fan drive system,the fault monitoring system for gear box and transmission shaft is designed.By using the programmable logic controller to acquire and process the signal of the gearbox oil temperature,vibration and transmission shaft,the system can alarm and stop the gear box and transmission shaft before failure occurrence with specific programs,which effectively avoids safety incidents.Combined with cooling tower fan intelligent control system,the system can realize the cooling tower fan’s intelligent inverter and start-stop,and fault early warning and shutdown.
