一、概述在华主席“抓纲治国”战略决策的鼓午下,为适应化工自动化发展的需要,我们试制了DTC采样调节器,并在上海炼油厂酚精制装置进行了现场运行试用,得到了一定的效果。 DTC采样调节器是一种与DDZ-Ⅱ型单元组合仪表配套使用的断续调节器,适合于对较大纯滞启的对象实现自动调节。为扩大仪表的功能,该表又可构成连续的P工调节器。本表主要部分采用线性集成电路,使线路简单,维修方便,同时可靠性、稳定性以及调节精度
I. Overview In order to meet the needs of the automation development of chemical industry under the auspices of Chairman Jiang’s strategic decision of “grasping the country with the rule of state and state,” we trial-produced the DTC sampling regulator and conducted trial operation on site in the phenol refining plant of Shanghai Refinery. A certain effect. DTC sampling regulator is a kind of intermittent regulator used with DDZ-Ⅱ type unit combination meter, which is suitable for automatically adjusting the object of large pure stagnation. In order to expand the function of the instrument, the meter can form a continuous P regulator. The main part of the table using linear integrated circuits, the line is simple, easy maintenance, while reliability, stability and accuracy
