在玻璃生产中,窑炉的玻璃液面控制是一项重要的工艺控制参数。液面波动大,对玻璃熔化及玻璃的产量、质量都会带来不利影响。液面的高低是以投料多少来控制的,当投料和成型取用的玻璃液量平衡时,液面就基本维持不变。本文介绍的是利用吹气法结合差压变送器和动圈指示调节仪来实现液面测量及自动控制的。控制原理见图1。 In glass production, the glass level control of the kiln is an important process control parameter. Fluctuations in the liquid surface, glass melting and glass production, quality will bring adverse effects. The level of the liquid is controlled by the amount of material to be fed. When the amount of liquid glass used for feeding and forming is balanced, the liquid level basically remains unchanged. This article describes the use of air method combined with differential pressure transmitter and moving coil indicator to achieve liquid level measurement and automatic control. Control principle shown in Figure 1.
