摘要
对选煤厂带式输送机原理进行了分析,探讨了变频器的节能原理,并根据带式输送机的实际工作情况,设计了基于PLC控制下的变频节能系统。采用重量信号作为反馈信号实现了闭环控制。实现了节能目的。
The principle of belt conveyor of coal preparation plant was analysed. Discusses the energy saving principle of frequency converter was discussed. According to the actual working condition of belt conveyor, the frequency energy - saving system was designed based on PLC control. Using the weight signals as feedback signal, the closed - loop control is realized. Achieve the purpose of energy saving.
