摘要
造纸生产流程中,各分部之间需要速度协调控制;在某些分部,如压榨部压榨形式采用真空辊带K式压榨时,为使K式压榨各传动电机根据各自的功率配置合理承担负荷功率输出,需采用负荷分配控制形式,整个生产线的速度协调问题可以选用PLC作为上位机,利用通讯实现对变频器的控制。森兰SB80变频器提供了丰富的串口协议,可方便组网控制。
Speed coordinate control among each unit is necessary in papermaking process. In some units such as squeeze unit, when K type squeeze with vacuum roller is selected, we use load distribution control in order to make each drive motor undertake the load power output which fits its power configuration in K type squeeze. PLC can be selected for upper machine to handle the speed coordinate of the whole production line. Inverter control comes through with the communication. Senlan SB80 Inverter provides plentiful protocols of serial port and easy to setup network and control.
