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。杭州直行程電氣閥門定位器報(bào)價(jià)定位器可以加快閥桿的移動速度,提升閥門的線性度。</p><div

style="text-indent:25px">定位器要避免閥自身不穩(wěn)定區(qū)工作法：有的定位器避免閥自身不穩(wěn)定區(qū)工作法，比如說雙座閥，開度在10％以內(nèi)，因上球處流開，下球處流閉，帶來不穩(wěn)定的問題；又或者是不平衡力變化斜率產(chǎn)生交變的附近，其穩(wěn)定性較差。這種情況下，需要我們避免不穩(wěn)定區(qū)工作即可。增大彈簧剛度法，執(zhí)行機(jī)構(gòu)抵抗負(fù)荷變化對行程影響的能力取決于彈簧剛度，剛度越大，對行程影響越小，定位器的穩(wěn)定性越好。電動高溫套筒調(diào)節(jié)閥增大彈簧剛度是提高定位器穩(wěn)定性的常見的簡單方法。</p><p style="text-indent:25px">閥門定位器上的法蘭螺母和螺栓要固定，防止受力不均勻?qū)е路ㄌm對接出現(xiàn)問題。閥門的密封材料要定期的清洗，防止泄露和磨損。在關(guān)閉的情況下，閥門定位器的閥體內(nèi)還有些許介質(zhì)殘留時，要切斷電源和氣源，把壓力全部釋放出來進(jìn)行清理。對氣動管路閥門進(jìn)行全開全閉數(shù)次操作，確認(rèn)閥門能夠正常工作，再檢查一次閥門的各個細(xì)節(jié)，保證閥門完好無損。讓閥門定位器安裝位置管線在同軸位置上，管線上兩片法蘭應(yīng)保持平行，確認(rèn)管線能夠承受氣動管路閥門自身重量，如果發(fā)現(xiàn)管線不能承受氣動管路閥門重量，則在安裝前為管線配備相應(yīng)的支撐。定位器的安裝步驟要遵守規(guī)范，避免不能正常使用。</p><div
