電動(dong)推桿由驅動(dong)電機、減(jian)速齒輪、螺桿、螺母(mu)、導套、推桿、滑(hua)座、彈簧、外殼及渦輪、微動(dong)控制開關等(deng)組(zu)成。

電(dian)動(dong)推桿是(shi)一(yi)(yi)種新(xin)(xin)型的電(dian)動(dong)執行機(ji)構(gou)，電(dian)動(dong)推桿主要由電(dian)機(ji)、推桿和(he)控(kong)制(zhi)(zhi)(zhi)裝置等機(ji)構(gou)組成(cheng)的一(yi)(yi)種新(xin)(xin)型直線執行機(ji)構(gou)，可以實(shi)現遠距離控(kong)制(zhi)(zhi)(zhi)、集中(zhong)控(kong)制(zhi)(zhi)(zhi)。電(dian)動(dong)推桿在(zai)一(yi)(yi)定范圍行程內作往返運動(dong)，一(yi)(yi)般(ban)電(dian)動(dong)推桿標準行程在(zai)，100，150，200，250，300，350，400mm，特殊行程也可根據不同(tong)應用條(tiao)件(jian)要求設計定做。

電(dian)(dian)動(dong)(dong)(dong)推(tui)(tui)桿可(ke)以根據(ju)不(bu)(bu)同的(de)(de)(de)應用負荷(he)而設計不(bu)(bu)同推(tui)(tui)力(li)的(de)(de)(de)電(dian)(dian)動(dong)(dong)(dong)推(tui)(tui)桿，一般(ban)其(qi)最大推(tui)(tui)力(li)可(ke)達6000N，空載運(yun)行(xing)(xing)速度為(wei)4mm~35mm/s，電(dian)(dian)動(dong)(dong)(dong)推(tui)(tui)桿以24V/12V直流永磁(ci)電(dian)(dian)機(ji)為(wei)動(dong)(dong)(dong)力(li)源(yuan)，把電(dian)(dian)機(ji)的(de)(de)(de)旋轉(zhuan)運(yun)動(dong)(dong)(dong)轉(zhuan)化(hua)為(wei)直線往復運(yun)動(dong)(dong)(dong)，推(tui)(tui)動(dong)(dong)(dong)一組連(lian)桿機(ji)構(gou)來完成風門(men)(men)(men)、閥(fa)門(men)(men)(men)、閘門(men)(men)(men)、擋板(ban)等(deng)切換工(gong)作。采用電(dian)(dian)動(dong)(dong)(dong)推(tui)(tui)桿作為(wei)執(zhi)(zhi)(zhi)行(xing)(xing)機(ji)構(gou)不(bu)(bu)僅可(ke)減少(shao)采用氣(qi)動(dong)(dong)(dong)執(zhi)(zhi)(zhi)行(xing)(xing)機(ji)構(gou)所(suo)需的(de)(de)(de)氣(qi)源(yuan)裝置和輔助設備，也可(ke)減少(shao)執(zhi)(zhi)(zhi)行(xing)(xing)機(ji)構(gou)的(de)(de)(de)重(zhong)量(liang)。氣(qi)動(dong)(dong)(dong)執(zhi)(zhi)(zhi)行(xing)(xing)機(ji)構(gou)在整個控(kong)制(zhi)運(yun)行(xing)(xing)過(guo)程中(zhong)都需要有(you)一定的(de)(de)(de)氣(qi)壓(ya)(ya)，雖然可(ke)采用消耗量(liang)小的(de)(de)(de)放大器(qi)等(deng)，但日積月累(lei)，耗氣(qi)量(liang)仍是巨(ju)大的(de)(de)(de)。采用電(dian)(dian)動(dong)(dong)(dong)推(tui)(tui)桿執(zhi)(zhi)(zhi)行(xing)(xing)機(ji)構(gou)，在改(gai)變控(kong)制(zhi)開(kai)度時，需要供電(dian)(dian)，在達到所(suo)需開(kai)度時就可(ke)不(bu)(bu)再供電(dian)(dian)，因此從節(jie)(jie)能看(kan)，電(dian)(dian)動(dong)(dong)(dong)推(tui)(tui)桿執(zhi)(zhi)(zhi)行(xing)(xing)機(ji)構(gou)比氣(qi)動(dong)(dong)(dong)執(zhi)(zhi)(zhi)行(xing)(xing)機(ji)構(gou)有(you)明(ming)顯節(jie)(jie)能優點。適(shi)用于(yu)遠距離操縱而廣泛(fan)用于(yu)電(dian)(dian)力(li)、化(hua)工(gong)、冶(ye)金、礦(kuang)山(shan)、輕工(gong)、交通(tong)、船舶等(deng)部門(men)(men)(men)的(de)(de)(de)風門(men)(men)(men)、閥(fa)門(men)(men)(men)、閘門(men)(men)(men)等(deng)機(ji)構(gou)的(de)(de)(de)啟閉、物料(liao)裝卸、流量(liang)控(kong)制(zhi)等(deng)，現已被越(yue)來越(yue)多的(de)(de)(de)部門(men)(men)(men)用它來代替(ti)機(ji)構(gou)手(shou)、液壓(ya)(ya)閥(fa)、減速傳(chuan)動(dong)(dong)(dong)機(ji)構(gou)的(de)(de)(de)自動(dong)(dong)(dong)裝置。
