带式输送机变频跟随控制技术的研究与运用

Research and application of frequency control technology of belt conveyor

为了解决付村选煤厂带式输送机的运行速度不能依据实际运输量及时调节的问题,结合问题原因分析,采用变频跟随控制技术对其进行升级改造。生产实践表明:该技术的应用,实现了对带式输送机电动机转速的合理控制,有效解决了轻载恒速和空载运行带来的电能浪费问题,达到了胶带运输系统整体节能的目标。

To regulate running speed of belt conveyor in time based on actual amount of carrying in Fucun coal preparation plant, frequency control technology is employed by analysis of the causes. The application shows that it can control motor speed of belt conveyor appropriately, solving the problem of no - load operation and constant speed at a little load, which save energy of the whole conveying system.
