電動推桿(gan)(gan)由(you)驅動電機、減速齒輪、螺桿(gan)(gan)、螺母(mu)、導套(tao)、推桿(gan)(gan)、滑座、彈簧、外殼(ke)及渦輪、微(wei)動控制開關等組成。

電(dian)(dian)(dian)動(dong)推桿(gan)(gan)是一種(zhong)(zhong)新型(xing)的(de)電(dian)(dian)(dian)動(dong)執行(xing)(xing)機構(gou)，電(dian)(dian)(dian)動(dong)推桿(gan)(gan)主要由電(dian)(dian)(dian)機、推桿(gan)(gan)和(he)控制裝置(zhi)等機構(gou)組成的(de)一種(zhong)(zhong)新型(xing)直線執行(xing)(xing)機構(gou)，可以實現遠距離控制、集中控制。電(dian)(dian)(dian)動(dong)推桿(gan)(gan)在(zai)一定范圍行(xing)(xing)程內(nei)作往返(fan)運動(dong)，一般電(dian)(dian)(dian)動(dong)推桿(gan)(gan)標(biao)準行(xing)(xing)程在(zai)，100，150，200，250，300，350，400mm，特殊行(xing)(xing)程也可根據不同應用條件(jian)要求設計定做。

電(dian)動(dong)推(tui)(tui)桿可(ke)(ke)以(yi)根(gen)據不(bu)同的(de)(de)應用(yong)負荷而設計不(bu)同推(tui)(tui)力(li)的(de)(de)電(dian)動(dong)推(tui)(tui)桿，一般(ban)其最大(da)推(tui)(tui)力(li)可(ke)(ke)達6000N，空載運(yun)(yun)行(xing)(xing)(xing)(xing)速度為4mm~35mm/s，電(dian)動(dong)推(tui)(tui)桿以(yi)24V/12V直(zhi)流(liu)永磁電(dian)機(ji)(ji)為動(dong)力(li)源(yuan)，把電(dian)機(ji)(ji)的(de)(de)旋轉(zhuan)運(yun)(yun)動(dong)轉(zhuan)化為直(zhi)線(xian)往(wang)復運(yun)(yun)動(dong)，推(tui)(tui)動(dong)一組連桿機(ji)(ji)構(gou)來完成風(feng)門、閥門、閘(zha)門、擋板等切換(huan)工(gong)作(zuo)。采(cai)用(yong)電(dian)動(dong)推(tui)(tui)桿作(zuo)為執(zhi)(zhi)行(xing)(xing)(xing)(xing)機(ji)(ji)構(gou)不(bu)僅可(ke)(ke)減少(shao)采(cai)用(yong)氣(qi)動(dong)執(zhi)(zhi)行(xing)(xing)(xing)(xing)機(ji)(ji)構(gou)所(suo)需(xu)的(de)(de)氣(qi)源(yuan)裝(zhuang)置和輔助設備，也可(ke)(ke)減少(shao)執(zhi)(zhi)行(xing)(xing)(xing)(xing)機(ji)(ji)構(gou)的(de)(de)重量。氣(qi)動(dong)執(zhi)(zhi)行(xing)(xing)(xing)(xing)機(ji)(ji)構(gou)在(zai)整個控制(zhi)運(yun)(yun)行(xing)(xing)(xing)(xing)過程中(zhong)都需(xu)要有一定的(de)(de)氣(qi)壓，雖然可(ke)(ke)采(cai)用(yong)消耗(hao)量小(xiao)的(de)(de)放大(da)器等，但日積(ji)月累，耗(hao)氣(qi)量仍是巨大(da)的(de)(de)。采(cai)用(yong)電(dian)動(dong)推(tui)(tui)桿執(zhi)(zhi)行(xing)(xing)(xing)(xing)機(ji)(ji)構(gou)，在(zai)改變(bian)控制(zhi)開(kai)度時(shi)(shi)，需(xu)要供電(dian)，在(zai)達到(dao)所(suo)需(xu)開(kai)度時(shi)(shi)就可(ke)(ke)不(bu)再供電(dian)，因此從節(jie)能看，電(dian)動(dong)推(tui)(tui)桿執(zhi)(zhi)行(xing)(xing)(xing)(xing)機(ji)(ji)構(gou)比氣(qi)動(dong)執(zhi)(zhi)行(xing)(xing)(xing)(xing)機(ji)(ji)構(gou)有明顯(xian)節(jie)能優點。適用(yong)于遠距離(li)操縱而廣泛用(yong)于電(dian)力(li)、化工(gong)、冶金、礦山、輕工(gong)、交通、船舶(bo)等部(bu)(bu)門的(de)(de)風(feng)門、閥門、閘(zha)門等機(ji)(ji)構(gou)的(de)(de)啟閉、物料裝(zhuang)卸、流(liu)量控制(zhi)等，現已被越來越多的(de)(de)部(bu)(bu)門用(yong)它來代替機(ji)(ji)構(gou)手、液壓閥、減速傳動(dong)機(ji)(ji)構(gou)的(de)(de)自動(dong)裝(zhuang)置。
