基于PLC的锅炉过热器水管半周堆焊自动控制系统

Automatic control system of semi-cycle hardfacing based on PLC for boiler superheater pipe

为提高锅炉过热器水管半周堆焊的自动化程度、实现较好的堆焊效果,将传统上重复的人工操作转化为智能性的自动化系统,以三菱FX系列PLC为核心设计了锅炉水管半周堆焊自动控制系统,经过与焊机通讯,以及三轴伺服电机的协调运动,从而达到最终的半周堆焊效果。该系统可通过触摸屏进行水管以及焊接要求等参数的设定,以适应多种直径水管的半周堆焊。通过最终的工厂试验,该系统实现了半周堆焊的自动控制,具有较高的堆焊精度,极大地提高工作效率、降低人力成本,同时保证了相比于人工堆焊更好的堆焊效果。该系统极大提高了产品自动化程度,在降低成本的同时,保证了较好的半周堆焊效果,满足最终使用要求。

In order to improve the automation degree of semi-cycle hardfacing of boiler superheater and achieve better results of hardfacing,automatic control system of semi-cycle hardfacing for the boiler evaporator tube was designed to replace the traditional manual repeated operation based on Mitsubishi FX series PLC system.And through the communication with welding machine,as well as coordinated action of3axis servo motor,the semi-cycle surfacing effect was finally achieved.The system can be used to set the parameters of the water pipe and welding through the touch screen to satisfy the semi-circle hardfacing for pipes with different diameters.According to the final test in the factory,the system not only realized the automatic control of semi-cycle hardfacing,achieved high precision,greatly improved work efficiency,reduced the labor cost,but also ensured the better welding results compared to the manual hardfacing.The system can greatly improve the degree of automation,reduce the cost,and ensure better welding effect,and eventually meet the requirements.
