基于触摸屏和PLC的无水溶剂计量系统

Metering System of Anhydrous Solvent Based on Touch Screen and PLC

无水溶剂的取用要求在隔绝空气条件下进行,给计量造成了麻烦。设计了自控系统,采用N2作为动力,同时可以隔绝空气。采用最新触摸屏技术,结合PLC对无水溶剂进行计量,取用方便。实时显示溶剂取用量,历史取用记录,报表制作,准确计量为产品的质量提供了保证。

Anhydrous solvent extraction requires in unair conditions,which cause trouble to meter.This paper designs automatic control system,using N2 as power,and can be isolated from the air.Using the latest touch screen technology,and PLC meters anhydrous solvent,convenient to take.Real time display of solvent extraction rates,access to historical records,the report authoring,accurate measurement for product quality process monitoring.
