The controlling principle of automatic operation,about the conveyor system of flying ashes pump system was de-scribed. Supplemented by analog module dealing with analog signals,PLC acted as the master controller,the level gauge and pressure transmitter were used to intelligently detect the height of the material and pressure conditions. The application of the touching screen could make the operation convenient and reflect the situation of the automatic operation of the conveyor system of flying ashes pump sys-tem in right time. The control system has the advantages of stability,high reliability,running easily,and improving the efficiency of the original conveying system. It enables flying ashes pump system to run normally without the watch of people and ensures the output of the system. At last,the possible failures during the operation and corresponding measures for flying ashes silo pump system were summarized.
