YD25-200型四柱式油压机电气控制线路的PLC改造

Modification of YD25-200 Four-column Hydraulic Press with Electric Control Line

因YD25-200型四柱式油压机在生产中电气控制系统经常发生故障,通过对故障原因进行分析,利用三菱PLC作为控制核心,对其继电控制电路进行改造。文章展示了传统继电器控制系统向PLC控制系统的改造过程,利用PLC电路替代继电电路,简化了原油压机的控制电路,提高电气系统的稳定性和可靠性,易于查故、便于维修,节省大量的继电器元件,使油压机的工作效率更高。

The YD25-200 type four-column hydraulic press often fails in the production of electrical control system.Through the analysis of the cause of the fault,the Mitsubishi PLC is used as the control core to transform the relay control circuit.The paper shows the transformation process of the traditional relay control system to the PLC control system,uses the PLC circuit instead of the relay circuit,simplifies the control circuit of the crude oil press,improves the stability and reliability of the electrical system,is easy to check,easy to repair and save a large number of relay components,so that the hydraulic press is more efficient.
