對于雙作用的氣動、液動、電動執(zhí)行機構(gòu)，一般都沒有復(fù)位彈簧。作用力的大小與它的運行方向無關(guān)，因此，選擇執(zhí)行機構(gòu)的關(guān)鍵在于弄清最大的輸出力和電機的轉(zhuǎn)動力矩R909427141 A2FO23/61R-PAB06

對執(zhí)行機構(gòu)輸出力確定后，根據(jù)工藝使用環(huán)境要求，選擇相應(yīng)的執(zhí)行機構(gòu)。對于現(xiàn)場有防爆要求時，應(yīng)選用氣動執(zhí)行機構(gòu)。從節(jié)能方面考慮，應(yīng)盡量選用電動執(zhí)行機構(gòu)。若調(diào)節(jié)精度高，可選擇液動執(zhí)行機構(gòu)。如發(fā)電廠透明機的速度調(diào)節(jié)、煉油廠的催化裝置反應(yīng)器的溫度調(diào)節(jié)控制等。A10VSO28DFLR/31R-PPA12N00?
