style="text-indent:25px">定位器在工作的時候有一些常見的問題，整理了一些問題幫助在使用中理解體會。1.定位器無法自整定：自整定時在屏幕上顯示這表示電角度不在規(guī)定范圍內(nèi)，這要求安裝時需注意，如下圖畫圈處所示，不要超出指示范圍。2.液晶無顯示：用萬用表帶載測量11、12端子直流電壓，觀察電壓正負(fù)極是否接線正確，沒問題需要確定11、12端子電壓是否在8.2-8.7V之間，電壓在這個范圍內(nèi)，一般為主板問題；電壓不在這個范圍內(nèi)，故障出在DCS接口或傳輸導(dǎo)線上。定位器遇到問題時要及時的進(jìn)行解決。定位器會克服液體對閥芯產(chǎn)生的不平衡力，減小行程誤差。揚(yáng)州雙作用閥門定位器正反作用</p><p

style="text-indent:25px">定位器降低響應(yīng)速度法，當(dāng)系統(tǒng)要求調(diào)節(jié)閥響應(yīng)或調(diào)節(jié)速度不應(yīng)太快時，閥的響應(yīng)和調(diào)節(jié)速度卻又較快，如流量需要微調(diào)，而調(diào)節(jié)閥的流量調(diào)節(jié)變化卻又很大，或者系統(tǒng)本身已是快速響應(yīng)系統(tǒng)而調(diào)節(jié)閥卻又帶定位器來加快閥的動作，這都是不利的。這將會產(chǎn)生超調(diào)，產(chǎn)生振動等。對此，應(yīng)降低響應(yīng)速度，有兩種方法可采用：將定位器的可改為轉(zhuǎn)換器、繼動器；或者將直線特性改為對數(shù)特性。定位器改變不平衡力作用方向法，在穩(wěn)定性分析中，已知不平衡力作用同與閥關(guān)方向相同時，電動高溫套筒調(diào)節(jié)閥即對閥產(chǎn)生關(guān)閉趨勢時，閥穩(wěn)定性差。對定位器工作在上述不平衡力條件下時，選用改變其作用方向的方法，通常是把流閉型改為流開型，一般來說都能方便地解決穩(wěn)定性問題定位器有一項(xiàng)十分重要的功能是故障診斷功能。在實(shí)際開工或調(diào)試過程中，我們會遇到各種各樣的問題。如何正確地判斷和解決這些問題，對裝置正常保護(hù)生產(chǎn)十分重要。特別是對智能定位器來說，診斷閥門泄漏量，閥填料，閥磨損等，是大部分智能定位器生產(chǎn)廠家提供的功能。除此之外，只能定位器大多具有自保聯(lián)鎖功能，定位器也接受外部連鎖信號的輸入。重慶閥門定位器報(bào)價</p></p><br
