一、交变湿热箱在升温过程中出现的异常现象1.交变湿热箱温度出现过冲现象,造成温度偏差过大出现这种现象的常见原因是:温度控制仪表的PID设置问题。温度控制仪表设定在某一温度点,当箱内温度接近仪表控制温度时,由于PID设置不好,导致仪表仍未作出切断或减小电流指令,造成箱内温度过冲,使箱内温度很难达到稳定状态。出现这种现象时,
First, the exchange of hot and humid boxes in the process of heating anomalies 1. Oxygen and humidifier temperature overshoot phenomenon, resulting in excessive temperature deviation This phenomenon is a common cause: the temperature control instrument PID settings. Temperature control instrument set at a certain temperature point, when the temperature inside the box close to the instrument control temperature, due to poor PID settings, the instrument has not yet cut off or reduce the current command, causing the temperature inside the box overshoot, so that the temperature inside the box Difficult to reach a steady state. When this phenomenon occurs,
