我公司矿山石灰石长胶带输送机原为2条2 500t/d生产线供料,采用“3+2”多电动机拖动方式和转子串水电阻启动方式。后来增加了一条5 000t/d生产线,为了满足生产需求,对该输送胶带机进行了提速、提产改造。机械方面增大了驱动滚筒及托辊直径,电气方面则更换大功率电动机(由160k W普通绕线式电动机改为220k W的变频电动机),并采用PLC与ACS800变频器控制,其中变频器采用ABB变频多传动控制系统中的主从控制模式。
The mine limestone long belt conveyor was originally used for 2 2 500t / d production line feeding, using “3 +2 ” multi-motor dragging method and rotor string water resistance start mode. Later added a 5000t / d production line, in order to meet production needs, the conveyor belt conveyor speed, raise production transformation. Mechanical increase the diameter of the drive roller and idler, the electrical replacement of high-power motor (from 160k W ordinary winding motor to 220k W inverter motor), and the use of PLC and ACS800 inverter control, in which the inverter ABB frequency conversion multi-drive control system master-slave control mode.
