摘要
水泥厂的皮带运输系统由于采用传统继电控制系统,故障率大,维修不便。采用了PLC与变频器结合的控制方案来替代继电控制系统,运行结果证明重建后的系统稳定、可靠,故障率降低,有效地降低企业故障成本,提高了企业经济效益。
Using traditional relay control system,delivery system of belt transport in cement plants results in failure rate and inconvenience maintenance.In order to reconstruct the system,the combination of PLC and frequency control scheme is used instead of the relay control system.Results prove the stability,reliability and lower failure of rebuilt system.It can reduce the enterprise＇s failure cost and increase its economic benefit.
