伯納德 6000Nm智能型整體式電動執行器YMB+RS600/K172H
調節(jie)器或(huo)變(bian)送器的(de)(de)模擬信(xin)(xin)號(hao)經模數轉換(huan)后(hou)進入位(wei)置定位(wei)器,位(wei)置定位(wei)器的(de)(de)微(wei)機(ji)(ji)定期檢測(ce)這個輸入信(xin)(xin)號(hao)和(he)位(wei)置反饋信(xin)(xin)號(hao),當兩(liang)個信(xin)(xin)號(hao)不平衡時,偏(pian)差(cha)一(yi)旦超出列(lie)區,立刻發(fa)出放(fang)大的(de)(de)控制信(xin)(xin)號(hao),驅(qu)動(dong)智(zhi)能(neng)(neng)位(wei)置定位(wei)器中的(de)(de)三相可逆(ni)固體繼(ji)電器或(huo)可控硅,使其導通帶(dai)動(dong)電機(ji)(ji)向(xiang)(xiang)減(jian)小偏(pian)差(cha)方向(xiang)(xiang)運(yun)轉,進而帶(dai)動(dong)減(jian)速機(ji)(ji)構井改變(bian)閥門(men)的(de)(de)開(kai)充。與此同時,微(wei)機(ji)(ji)也(ye)將閥門(men)開(kai)度(du)的(de)(de)位(wei)置信(xin)(xin)號(hao)轉換(huan)為數字脈沖信(xin)(xin)號(hao)送往顯示器,從數顯窗可觀察閥門(men)的(de)(de)開(kai)度(du)。A、實現(xian)控制,改善控制性能(neng)(neng),要(yao)求對(dui)現(xian)場進行監控,出現(xian)故障進能(neng)(neng)及(ji)時處理或(huo)停機(ji)(ji)。B、控制要(yao)求十分嚴格,需(xu)要(yao)對(dui)閥或(huo)過程變(bian)量進行連續(xu)監測(ce)和(he)準(zhun)確診斷并進行設定、調整(zheng)的(de)(de)精密控制系統(tong)。

SD系列電動執行機構按安裝方式分成二種:
1.直(zhi)聯式(shi)一通(tong)過執(zhi)行(xing)(xing)(xing)機構輸(shu)出(chu)部(bu)位(wei)的法蘭與閥門等直(zhi)接連(lian)接,這(zhe)樣執(zhi)行(xing)(xing)(xing)機構可直(zhi)接安(an)裝在(zai)管道上多(duo)轉多(duo)、角行(xing)(xing)(xing)程、直(zhi)行(xing)(xing)(xing)程均用(yong)此種方法安(an)裝。2、底座(zuo)式(shi)一執(zhi)行(xing)(xing)(xing)機構通(tong)過輸(shu)出(chu)臂及杠桿與閥門連(lian)接,此時執(zhi)行(xing)(xing)(xing)機構需要安(an)裝在(zai)-基(ji)礎臺座(zuo)上,僅角行(xing)(xing)(xing)程用(yong)這(zhe)種方式(shi)安(an)裝。
SD系列電動(dong)(dong)(dong)(dong)(dong)執行機構(gou)是自(zi)動(dong)(dong)(dong)(dong)(dong)調節系統的終端(duan)控制(zhi)裝置,它(ta)接收來(lai)自(zi)調節器(qi)(qi)或(huo)計(ji)算機送來(lai)420mA(或(huo)1-5V)模似(si)量信(xin)(xin)號及斷續接點控制(zhi)信(xin)(xin)號。輸出(chu)力矩或(huo)力,自(zi)動(dong)(dong)(dong)(dong)(dong)地操(cao)縱調節機構(gou),完成自(zi)動(dong)(dong)(dong)(dong)(dong)調節任務。它(ta)也可以通過操(cao)作器(qi)(qi)實(shi)現(xian)“手動(dong)(dong)(dong)(dong)(dong)自(zi)動(dong)(dong)(dong)(dong)(dong)"轉換,切換到(dao)手動(dong)(dong)(dong)(dong)(dong)時,用(yong)操(cao)作器(qi)(qi)對執行機構(gou)進行遠(yuan)方控制(zhi).
