紅(hong)(hong)外(wai)線輻射加(jia)(jia)熱(re)(re)(re)器(qi)是(shi)目前(qian)工業(ye)生產中(zhong)常(chang)用的加(jia)(jia)熱(re)(re)(re)設(she)備，其特點是(shi)可以利(li)用輻射熱(re)(re)(re)能(neng)(neng)快速(su)將物體加(jia)(jia)熱(re)(re)(re)到所需溫(wen)(wen)度(du)(du)(du)，具(ju)有效率(lv)高(gao)、節(jie)能(neng)(neng)環保等優點。而恒溫(wen)(wen)不(bu)滅(mie)燈，則是(shi)利(li)用PID控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)技(ji)術使(shi)加(jia)(jia)熱(re)(re)(re)器(qi)在長時(shi)間運行(xing)過程(cheng)中(zhong)保持恒定的溫(wen)(wen)度(du)(du)(du)狀態，PID控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)是(shi)一(yi)(yi)種經典的閉(bi)環控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)方法，其基本(ben)思想(xiang)是(shi)通過不(bu)斷(duan)測量(liang)物理量(liang)（如(ru)溫(wen)(wen)度(du)(du)(du)、流量(liang)、壓力(li)等）并與設(she)定值進行(xing)比較(jiao)，以計算出一(yi)(yi)個(ge)修正量(liang)來控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)某個(ge)過程(cheng)的輸(shu)出。在紅(hong)(hong)外(wai)線加(jia)(jia)熱(re)(re)(re)管(guan)的控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)過程(cheng)中(zhong)，傳感器(qi)會(hui)不(bu)斷(duan)測量(liang)加(jia)(jia)熱(re)(re)(re)管(guan)的溫(wen)(wen)度(du)(du)(du)，并將結果反饋給(gei)控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)。控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)會(hui)根據當前(qian)的溫(wen)(wen)度(du)(du)(du)偏差(cha)（也就是(shi)實際(ji)溫(wen)(wen)度(du)(du)(du)與目標溫(wen)(wen)度(du)(du)(du)之(zhi)差(cha)）計算出一(yi)(yi)個(ge)修正量(liang)，調(diao)整(zheng)(zheng)加(jia)(jia)熱(re)(re)(re)管(guan)的加(jia)(jia)熱(re)(re)(re)功(gong)率(lv)，使(shi)其溫(wen)(wen)度(du)(du)(du)逐漸逼近目標溫(wen)(wen)度(du)(du)(du)。當溫(wen)(wen)度(du)(du)(du)達到設(she)定的目標溫(wen)(wen)度(du)(du)(du)時(shi)，控(kong)(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)會(hui)停止調(diao)整(zheng)(zheng)加(jia)(jia)熱(re)(re)(re)功(gong)率(lv)，保持加(jia)(jia)熱(re)(re)(re)管(guan)的恒溫(wen)(wen)狀態，同(tong)時(shi)不(bu)影響加(jia)(jia)熱(re)(re)(re)管(guan)的使(shi)用壽(shou)命。

在連(lian)續傳送的(de)涂布機等輸送線(xian)上，突然的(de)滅燈將意味著紅(hong)外線(xian)輻射消失，只能依靠爐內熱(re)氣對產(chan)(chan)(chan)(chan)品(pin)進行低(di)效(xiao)加熱(re)，這(zhe)會對產(chan)(chan)(chan)(chan)品(pin)的(de)輻射加熱(re)一致性造成致命(ming)的(de)打擊，從(cong)而(er)導致產(chan)(chan)(chan)(chan)品(pin)質(zhi)量下降和生產(chan)(chan)(chan)(chan)線(xian)的(de)損失。因此，保持(chi)紅(hong)外線(xian)加熱(re)器的(de)恒(heng)定溫度非常(chang)重(zhong)要，恒(heng)溫不滅燈的(de)特性將加強生產(chan)(chan)(chan)(chan)過程中的(de)穩定性、可靠性和生產(chan)(chan)(chan)(chan)效(xiao)率，從(cong)而(er)使工業(ye)生產(chan)(chan)(chan)(chan)變得(de)更加高效(xiao)、可持(chi)續和環保。

1、響應速度(du)快：PID控(kong)制器(qi)可以(yi)快速反應并(bing)調整輸出，尤其對(dui)于(yu)加熱管這樣響應速度(du)較快的物(wu)理過(guo)程(cheng)來說，PID控(kong)制可以(yi)實現快速準確的控(kong)制。2、穩定性(xing)好：PID控制可以根據系統狀態的變化進行自適應控制，具有較好的穩(wen)定性，可以穩(wen)定地控制溫度(du)。

3、誤差小：通過精確(que)的測量和(he)動態調整，PID控(kong)制(zhi)(zhi)可以使目標溫度(du)(du)與實際溫度(du)(du)之(zhi)間的誤差控(kong)制(zhi)(zhi)在(zai)較(jiao)小的范圍內，提高了加熱管的溫度(du)(du)控(kong)制(zhi)(zhi)精度(du)(du)。

4、自適(shi)應(ying)性(xing)強：PID控制可(ke)以(yi)(yi)根據系統的(de)變化進行自適應控制，對于不同(tong)的(de)物理參數和環境因素具有良好的(de)適應性，可(ke)以(yi)(yi)適應各(ge)種加(jia)熱管工(gong)況。

5、易于調(diao)節(jie)：PID控制(zhi)器通(tong)常具(ju)有(you)簡(jian)單(dan)的參數設置，可以根(gen)據(ju)具(ju)體(ti)物理過程(cheng)和環境(jing)來進行(xing)調(diao)節(jie)和優化。
