皮带运输机变频调速控制系统的改造与应用

Transformation and Application of Variable Frequency Speed Regulation Control System for the Belt Conveyor

针对官地矿皮带输送机的运行故障问题,基于PLC技术对电气控制系统进行变频改造,优化皮带运输机的电机启动方式及控制回路。通过改造实现了设备的安全启动和各种保护提示及投切等功能,输送机的故障自动检测和检修时间大幅缩减,同时降低了检修难度和维修成本。

In order to solve the problem of the operation of the belt conveyor in the mine belt conveyor,the frequency conversion of the electric control system is carried out based on the PLC technology,and the starting mode of the motor and the optimization of the control loop of the belt conveyor are optimized.The automatic detection and maintenance time of the conveyor is greatly reduced,and the maintenance difficulty and the maintenance cost are reduced.
