style="text-indent:25px">電動執(zhí)行器工作原理：下面簡要介紹一下直行程電動執(zhí)行器和角行程電動執(zhí)行器。直行程與角行程電動執(zhí)行器的工作原理是接收調(diào)節(jié)器或其它儀表送來的4~20毫安的標(biāo)準(zhǔn)值流電信號，經(jīng)執(zhí)行器后變成位移推力或轉(zhuǎn)角力矩，以操作開關(guān)、閥門等，完成自動調(diào)節(jié)的任務(wù)。這兩種執(zhí)行器以前都是由伺服放大器與執(zhí)行機(jī)構(gòu)兩大部分組成的?，F(xiàn)在有機(jī)電一體智能化的結(jié)構(gòu)，它們的結(jié)構(gòu)、工作原理和使用方法都是相似的，區(qū)別*在于，一個輸出位移（推力），一個輸出轉(zhuǎn)角（力矩）。濟(jì)南

-個信號(例75%)，執(zhí)行機(jī)構(gòu)會全開到底，然后回到指定位置(75%)。故障判斷和檢修過程:根據(jù)以上故障現(xiàn)象，首先要判斷是伺放板和執(zhí)行機(jī)構(gòu)那一個有問題。將伺放板從執(zhí)行機(jī)構(gòu)上拆下，直接將電源線接到X5/1和X5/4 端子上，執(zhí)行機(jī)構(gòu)關(guān)方向動作，將電源線接到X5/1和X5/2端子.上，執(zhí)行機(jī)構(gòu)開方向動作，如果執(zhí)行機(jī)構(gòu)動作不正常，說明故障在執(zhí)行器上。用萬用表測電機(jī)繞組正常，再測電容兩邊的電阻發(fā)現(xiàn)有一-個開路，將其更換后故障排除。結(jié)論:遇到以上故障現(xiàn)象時，首先要判斷故障發(fā)生在那一個部分上，好后確定根源。2、故障現(xiàn)象:執(zhí)行機(jī)構(gòu)通電后給關(guān)信號(4mA)執(zhí)行機(jī)構(gòu)先全開后再全關(guān)。故障判斷和檢修過程:先拆除伺放板，直接給執(zhí)行機(jī)構(gòu)通電發(fā)現(xiàn)仍然存在原故障,檢查電阻，電阻阻值正常。</p><p style="text-indent:25px">連續(xù)控制：如果執(zhí)行機(jī)構(gòu)被要求用于控制過程系統(tǒng)的液位、流量或壓力等參數(shù)，這是要求執(zhí)行機(jī)構(gòu)頻繁動作的工作，可以用4-20mA或0～10V的模擬量作為控制信號，然而這個信號可能會和過程一樣頻繁的改變。如果需要非常高頻率動作的執(zhí)行機(jī)構(gòu)，只有選擇特殊的能頻繁啟停的調(diào)節(jié)型執(zhí)行機(jī)構(gòu)。當(dāng)一個過程中需要多臺執(zhí)行機(jī)構(gòu)時，可以通過使用數(shù)字通訊系統(tǒng)將各個執(zhí)行機(jī)構(gòu)連接起來，這樣可較大降低安裝費(fèi)用。數(shù)字通訊回路可以快速高效的傳遞指令和收集信息。自動控制閥好大的好處是可以遠(yuǎn)距離的操作閥門，這就意味著操作人員可以坐在控制室控制生產(chǎn)過程而不需要親臨現(xiàn)場去人工操作閥門的開和關(guān)。人們只需鋪設(shè)一些管線連接控制室和執(zhí)行機(jī)構(gòu)，驅(qū)動能源通過管線直接激勵電動或氣動執(zhí)行機(jī)構(gòu)，通常用的4-20mA信號來反饋閥門的位置。執(zhí)行機(jī)構(gòu)可根據(jù)功能需求的變化，只要對驅(qū)動元件進(jìn)行可編程控制即可實(shí)現(xiàn)復(fù)雜多變的輸出運(yùn)動。</p><div
