style="text-indent:25px">電動(dòng)執(zhí)行器工作原理：下面簡要介紹一下直行程電動(dòng)執(zhí)行器和角行程電動(dòng)執(zhí)行器。直行程與角行程電動(dòng)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(dòng)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(gè)輸出位移（推力），一個(gè)輸出轉(zhuǎn)角（力矩）。</p><p style="text-indent:25px">電動(dòng)執(zhí)行器的安裝：執(zhí)行器應(yīng)安裝在便于調(diào)整、檢查和拆卸的地方。在保證安全生產(chǎn)的同時(shí)也應(yīng)該考慮節(jié)約投資、整齊美觀。這里介紹一些安裝的原則。執(zhí)行器好好是正立垂直安裝于水平管道上。執(zhí)行器應(yīng)安裝在靠近地面或樓板的地方，在其上、下方應(yīng)留有足夠的間隙。控制閥安裝在管道.上時(shí)，閥體上的箭頭方向與管道中流體流動(dòng)方向應(yīng)相同。如果控制閥的口徑與管道的管徑不同時(shí)，兩者之間應(yīng)加一個(gè)漸縮管來連接。為防止執(zhí)行機(jī)構(gòu)的薄膜老化，執(zhí)行器應(yīng)盡量安裝在遠(yuǎn)離高溫、振動(dòng)、有毒、及腐蝕嚴(yán)重的場地。當(dāng)生產(chǎn)現(xiàn)場有檢測儀表時(shí)，控制閥應(yīng)盡量與其靠近，以利于調(diào)整外，要注意工藝過程對控制閥位置的要求。為了安全起見，控制閥應(yīng)加旁通管路，并裝有切斷閥及旁路閥。以便在控制閥發(fā)生故障或維修時(shí)，通過旁路使生產(chǎn)過程繼續(xù)進(jìn)行。執(zhí)行機(jī)構(gòu)驅(qū)動(dòng)源獲取簡單，且運(yùn)行成本更為低廉。</p><div
