style="text-indent:25px">電動執(zhí)行器的要求：1.停電或調(diào)節(jié)器發(fā)生故障時，應(yīng)該能夠在執(zhí)行器上進行手動操作，以便采取應(yīng)急措施。為此，必須有離合器及手輪。2.在執(zhí)行器進行手動操作時，為了給調(diào)節(jié)器提供自動追蹤依據(jù)（追蹤是無擾動切換的需要），執(zhí)行器上應(yīng)該有閥位追蹤信號。這既是執(zhí)行器本身位置反饋的需要，也是閥位指示的需要。3.為了保護閥門及傳動機構(gòu)不致因過大的操作力而損壞，執(zhí)行器上應(yīng)有限位裝置和限制力或轉(zhuǎn)矩的裝置。除了以上基本要求之外，為了便于和各種閥門特性配合，好好能在執(zhí)行器上具有可選擇的非線性特性。為了能和計算機配合，好好能直接輸入數(shù)字信號。近些年來還有帶PID運算功能的執(zhí)行器，這就是所謂“數(shù)字執(zhí)行器”和“智能執(zhí)行器”。目前應(yīng)用好較廣的還是模擬式電動執(zhí)行器，其中以我國電動單元組合儀表里的DKJ（輸出為轉(zhuǎn)角）和DKZ型（輸出為直線位移）好為普遍。執(zhí)行機構(gòu)動作時間取決于電機或齒輪的減速比。山東

style="text-indent:25px">伺服放大器的原理：在自動控制系統(tǒng)中，這些執(zhí)行機構(gòu)需要**式的伺服放大器進行開關(guān)控制。電動執(zhí)行機構(gòu)的指令信號與閥位反饋信號在伺服放大器中進行比較放大后，經(jīng)過可控硅送出220V的開關(guān)信號。伺服放大器是由電器元件組成的電子線路板構(gòu)成，分前置級磁放大器線路板、觸發(fā)器線路板、可控硅交流開關(guān)線路板三部分。電動執(zhí)行機構(gòu)的指令信號與閥位反饋信號的比較放大靠這些電子線路板的運行來實現(xiàn)。伺服放大器有兩種模式可供選擇:一種為執(zhí)行機構(gòu)本身的控制板上帶有伺服放大器功能，結(jié)構(gòu)緊湊，不需占有儀表盤后空間，安裝及調(diào)試較為簡單（即電子一體化）。另一種為單獨放置的位置定位器，安裝于儀表盤后，這是一種較為傳統(tǒng)的應(yīng)用方法，檢修及更換較為容易（即分立式比例調(diào)節(jié)型）。山東
