一提起锅炉液位控制,大家立刻会想到搞三冲量调节.大家都认为三冲量调节抗干扰能力强,调节品质比单冲量、双冲量效果好,液位稳定.翻开书本看看,又都是介绍象图一所示的原理图.尽管其系统组成方式各有差异,但用这三个信号组成三冲量,则是完全相同的. A mention of the boiler level control, we immediately think of engaging three impulse regulation. We all think that three impulse adjustment anti-interference ability, adjust the quality than the single impulse, double impulse effect, liquid level stability. Open the book to see, both Is to introduce the schematic diagram shown in Figure 1. Although the system composed of different ways, but the composition of these three signals three impulse, is exactly the same.
