Design and Application on High Temperature and Pressure Crushing Mechanical Control System
In order to realize the continuous operation of high temperature and pressure crushing machinery,an electrical control system with new architecture is developed by means of theoretical design and simulation verification.According to the process configu-ration of a certain petrochemical project,the conventional"one control one"explosion-proof electrical control cabinet is upgraded to the"one control and multiple"mode in the site,and placed in a safe area,which effectively reduces the safety risks and costs,and a-chieves the centralized control.The control system adopts the Siemens latest PLC1517H redundant CPU to communicate the distribu-ted I/O in a redundant manner.The modular programming,UDT structure,permanent area and other methods are used to make the programming and configuration more accurate and efficient.The safe and reliable MODBUS RTU is used to communicate with the central control system,so it can monitor the running state of the equipment.Through the on-site operation feedback,the control system ensures the stable and reliable operation of the equipment,which has better operation and maintenance convenience.
