针对当前黄泥灌浆系统中螺旋给料机无法精确定量给料、发生堵塞时无法及时报警的现状,笔者结合LabVIEW监测与控制平台,设计了给料量为50m3/h螺旋给料机的状态监测与变频调速反馈控制系统。该系统由称重传感器、数据采集卡、LabVIEW上位机、RS485通信模块和变频器等组成,利用PID调节原理和RS485串口通信,可实现对螺旋给料机运行状态的监测、堵塞报警、精确定量给料和输送量从10～50m3/h的无级变化,保护了电动机,减轻了制浆机的压力。
In view of the current situation that the screw feeder in the yellow mud grouting system can not be accurately dosed and the alarm can not be timely detected when the blockage occurs, the author combined the LabVIEW monitoring and control platform to design the condition monitoring of the screw feeder with a feeding volume of 50m3 / h And frequency conversion speed feedback control system. The system consists of load cell, data acquisition card, LabVIEW host computer, RS485 communication module and frequency converter and other components. The use of PID regulation principle and RS485 serial communication can be achieved on the screw feeder running status monitoring, blocking alarm, accurate quantitative Feed and delivery volume from 10 ~ 50m3 / h stepless change, protecting the motor, reducing the pressure of the pulp machine.
