当前工业生产已大量使用电加热元件,势必造成用电量的紧张。文中从既满足生产工艺要求,又能节约电能着眼,对采用电加热元件加热的物体温度如何实施自动调节,提出了四种控制方法。在四种控制方法中采用XCT-19型动圈指示调节仪,组成无触点、输出为模似量电流信号的温度自动调节系统是先进的控制手段。该调节仪除输出信号是模似量电流外,还具有PID(比例、积分、微分)调节功能。使被电加热元件所加热物体的温度调节不再出现偏差,达到生产工艺所要求的控制值。并介绍了最近完成的环道试验室热循环水罐温度自动调节系统的组成和运行情况。
Current industrial production has been extensive use of electric heating elements, is bound to result in electricity consumption. In this paper, not only meet the requirements of the production process, but also save electricity, the use of electric heating elements heated objects how to implement automatic adjustment, proposed four control methods. In the four control methods using XCT-19-type moving coil indicator regulator to form a contactless, the output is analog current signal temperature automatic adjustment system is an advanced control method. The regulator in addition to the output signal is analog current, but also with PID (proportional, integral, differential) regulation. The electric heating element is heated to adjust the temperature of the object no longer appear deviation, to achieve the required control of the production process value. And introduced the composition and operation of the recently completed loop laboratory thermostat thermostat temperature control system.
