The design of the control system of pneumatic conveying for coal ash based on PLC

摘要

According to the transport characteristics of coal ash and dust, a pneumatic conveying equipment control system for coal ash is designed in this paper. The automatic control of pneumatic conveying equipment is realized. The structure of mechanical system, control system hardware, system software and man-machine interface are introduced. The project practice shows that the ash conveying system based on this control function is reliable and easy to operate. It not only safeguards the safety and stability of the production equipment and the economic operation. It also protects the civilized environment.
