Rotork電動(dòng)執(zhí)行器，REMOTE CONTROL執(zhí)行器原裝全新
Rotork電動(dòng)執(zhí)行機(jī)構(gòu)以交流伺服電動(dòng)機(jī)為驅(qū)動(dòng)裝置的位皿伺服機(jī)構(gòu)，由配接的位置定位器PM-2控制板接受調(diào)節(jié)系統(tǒng)的4~20mA直流控制信號(hào)與位置發(fā)送器的位置反饋借號(hào)進(jìn)行比較，比較后的信號(hào)偏差經(jīng)過放大使功率級(jí)導(dǎo)通，電動(dòng)機(jī)旋轉(zhuǎn)驅(qū)動(dòng)執(zhí)行機(jī)構(gòu)的輸出件朝著減小這一偏差的方向移動(dòng)(位置發(fā)送器不斷將輸出件的實(shí)際位置轉(zhuǎn)變?yōu)殡娦盘?hào)-位盈反饋信號(hào)送至位致定位器)，直到偏差信號(hào)小于設(shè)定值為止。此時(shí)執(zhí)行機(jī)構(gòu)的輸出件就穩(wěn)定在與輸人信號(hào)相對(duì)應(yīng)的位置上。
Rotork執(zhí)行機(jī)構(gòu)用于把閥門驅(qū)動(dòng)至全開或全關(guān)的位置。用于控制閥的執(zhí)行機(jī)構(gòu)能夠的使閥門走到任何位置。盡管大部分執(zhí)行機(jī)構(gòu)都是用于開關(guān)閥門，但是如今的執(zhí)行機(jī)構(gòu)的設(shè)計(jì)遠(yuǎn)遠(yuǎn)超出了簡(jiǎn)單的開關(guān)功能，它們包含了位置感應(yīng)裝置，力矩感應(yīng)裝置，電極保護(hù)裝置，邏輯控制裝置，數(shù)字通訊模塊及PID控制模塊等，而這些裝置全部安裝在一個(gè)緊湊的外殼內(nèi)。
