SIEMENS变频器和PLC在硅胶自动添加调速系统中的应用

提高和稳定啤酒在保质期内的质量，关键因素是准确控制硅胶添加量和硅胶与啤酒的反应时间。文章叙述了硅胶自动添加调速系统的组成、原理，介绍了一种采用Siemens的MM42~变频器和PLC组成的变频调速系统来控制硅胶自动添加的方法。

The Application of Siemens Converter and PLC in Adjust Speed System of the Gum of Silicon Increases Automatically

Raise and stabilize the quality of the beer in a period of protect, the key factor is control that the increases of accurate quantity of gum of silicon and the reaction time of gum of silicon and beers. This paper describes the compose and theory of the gum of silicon increases automatically. Introduces the control approach of Siemens converter and PLC in adjust speed system of the gum of silicon increases automatically.
