電動推桿(gan)由驅(qu)動電機、減速齒輪、螺(luo)桿(gan)、螺(luo)母、導套、推桿(gan)、滑座、彈簧、外殼及渦輪、微動控(kong)制開關等組成。

電(dian)動(dong)推(tui)桿(gan)是一(yi)(yi)(yi)種新型的電(dian)動(dong)執行(xing)機(ji)(ji)構(gou)(gou)，電(dian)動(dong)推(tui)桿(gan)主要(yao)由電(dian)機(ji)(ji)、推(tui)桿(gan)和控(kong)制裝置(zhi)等機(ji)(ji)構(gou)(gou)組成的一(yi)(yi)(yi)種新型直線執行(xing)機(ji)(ji)構(gou)(gou)，可以實(shi)現遠(yuan)距離(li)控(kong)制、集中控(kong)制。電(dian)動(dong)推(tui)桿(gan)在一(yi)(yi)(yi)定(ding)范圍行(xing)程內作往返運動(dong)，一(yi)(yi)(yi)般電(dian)動(dong)推(tui)桿(gan)標準(zhun)行(xing)程在，100，150，200，250，300，350，400mm，特殊行(xing)程也可根(gen)據不同應用條件要(yao)求(qiu)設計定(ding)做。

電(dian)(dian)動(dong)(dong)推(tui)桿(gan)可(ke)(ke)以根據不同的(de)應用(yong)負(fu)荷而設計不同推(tui)力的(de)電(dian)(dian)動(dong)(dong)推(tui)桿(gan)，一(yi)般(ban)其最大推(tui)力可(ke)(ke)達6000N，空載運行(xing)(xing)速(su)度為(wei)(wei)(wei)4mm~35mm/s，電(dian)(dian)動(dong)(dong)推(tui)桿(gan)以24V/12V直流永磁電(dian)(dian)機(ji)(ji)(ji)為(wei)(wei)(wei)動(dong)(dong)力源(yuan)，把(ba)電(dian)(dian)機(ji)(ji)(ji)的(de)旋轉運動(dong)(dong)轉化(hua)為(wei)(wei)(wei)直線往復運動(dong)(dong)，推(tui)動(dong)(dong)一(yi)組連桿(gan)機(ji)(ji)(ji)構(gou)來完(wan)成(cheng)風(feng)門(men)(men)(men)、閥(fa)門(men)(men)(men)、閘(zha)門(men)(men)(men)、擋板等(deng)切換(huan)工(gong)(gong)作(zuo)。采(cai)用(yong)電(dian)(dian)動(dong)(dong)推(tui)桿(gan)作(zuo)為(wei)(wei)(wei)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)(ji)構(gou)不僅可(ke)(ke)減少(shao)采(cai)用(yong)氣(qi)動(dong)(dong)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)(ji)構(gou)所(suo)需的(de)氣(qi)源(yuan)裝置和輔助設備，也可(ke)(ke)減少(shao)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)(ji)構(gou)的(de)重量(liang)。氣(qi)動(dong)(dong)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)(ji)構(gou)在(zai)整個控(kong)制(zhi)運行(xing)(xing)過程中(zhong)都需要(yao)有(you)(you)一(yi)定的(de)氣(qi)壓，雖然可(ke)(ke)采(cai)用(yong)消耗量(liang)小的(de)放大器等(deng)，但日積月累(lei)，耗氣(qi)量(liang)仍是巨(ju)大的(de)。采(cai)用(yong)電(dian)(dian)動(dong)(dong)推(tui)桿(gan)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)(ji)構(gou)，在(zai)改變控(kong)制(zhi)開度時(shi)(shi)，需要(yao)供(gong)電(dian)(dian)，在(zai)達到所(suo)需開度時(shi)(shi)就可(ke)(ke)不再供(gong)電(dian)(dian)，因此從節能看，電(dian)(dian)動(dong)(dong)推(tui)桿(gan)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)(ji)構(gou)比(bi)氣(qi)動(dong)(dong)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)(ji)構(gou)有(you)(you)明顯(xian)節能優點。適用(yong)于遠距離操(cao)縱而廣泛用(yong)于電(dian)(dian)力、化(hua)工(gong)(gong)、冶(ye)金(jin)、礦山(shan)、輕工(gong)(gong)、交通、船(chuan)舶等(deng)部(bu)門(men)(men)(men)的(de)風(feng)門(men)(men)(men)、閥(fa)門(men)(men)(men)、閘(zha)門(men)(men)(men)等(deng)機(ji)(ji)(ji)構(gou)的(de)啟閉、物料裝卸、流量(liang)控(kong)制(zhi)等(deng)，現已被越(yue)來越(yue)多的(de)部(bu)門(men)(men)(men)用(yong)它(ta)來代替機(ji)(ji)(ji)構(gou)手、液壓閥(fa)、減速(su)傳(chuan)動(dong)(dong)機(ji)(ji)(ji)構(gou)的(de)自動(dong)(dong)裝置。
