北京分析仪器厂生产的KH-01型红外仪,可以迅速测定气氛的CO_2量。不足的是,其调节器存在一些问题,很难直接用于自动控制。我们对此作了一些修改,经调试后用于吸热式发生器的CO_2自动控制,取得了一定效果。本文简要介绍改装、调试和使用的一些情况。我厂的吸热式气氛是用城市煤气制备的。由于城市煤气成分波动较大,需对产气的CO_2量进行自动控制。KH-01红外仪对吸热式发生器CO_2进行自动控制的原理示于图1。其中调节器是比例一复位重调式的,为便于讨论,先略去其复位重调环节,简化为比例式,并将其方块图示于图2。众所周知,
Beijing Analytical Instrument Factory production KH-01-type infrared instrument, you can quickly determine the amount of CO_2 atmosphere. The downside is that its regulators have some problems and are difficult to use directly for automatic control. We made some changes to this, after debugging for endothermic generator CO_2 automatic control, and achieved some results. This article briefly introduces some of the modifications, debugging, and use cases. The heat-absorbing atmosphere of our factory is made with city gas. Due to the large fluctuation of the city gas composition, the amount of CO 2 gas to be produced should be controlled automatically. KH-01 infrared instrument on the endothermic generator CO_2 automatic control principle shown in Figure 1. Regulator which is the proportion of a reset retarder, for ease of discussion, omit its reset the first re-tune links, reduced to proportional and its block diagram shown in Figure 2. As we all know,
