配料计量控制系统的设计

Design of Measure Control System for General Dispensing Material System

采用可编程序控制技术及人机工程学方法的人机操作界面设计计量装置电控系统,具有结构简单、运行可靠、效率高的特点.阐述了有关PLC功能检测模块,计量装置在自动的状态下能在2 100～6 000kg/h的萤石给料量下稳定的运行.实际应用说明,每小时给料累计值准确率不低于±0.5%.系统稳定时,给料瞬时流量偏差不大于±5%.

Design the measuring device controlled system based on PLC technical, and human-computer interface based on human-machine engineering. The high-accuracy batching depends on the effective control system. The measurement course of measuring apparatus that this text introduced was measured to the reduction of the supplies in the hopper, specializing in reducing and calling again. The precision of batching is up to ± 0. 5% grades.
