電(dian)動(dong)推桿由驅動(dong)電(dian)機、減速齒(chi)輪、螺(luo)桿、螺(luo)母、導套、推桿、滑座(zuo)、彈(dan)簧、外殼及(ji)渦輪、微動(dong)控制開關等組成。

電(dian)(dian)動(dong)推桿是一種(zhong)新型的電(dian)(dian)動(dong)執行機(ji)構(gou)，電(dian)(dian)動(dong)推桿主要(yao)由電(dian)(dian)機(ji)、推桿和控制(zhi)(zhi)裝置等機(ji)構(gou)組成(cheng)的一種(zhong)新型直線(xian)執行機(ji)構(gou)，可(ke)以實現遠距離控制(zhi)(zhi)、集(ji)中控制(zhi)(zhi)。電(dian)(dian)動(dong)推桿在(zai)一定(ding)范圍(wei)行程內(nei)作往返(fan)運動(dong)，一般電(dian)(dian)動(dong)推桿標準行程在(zai)，100，150，200，250，300，350，400mm，特殊行程也可(ke)根據不同應用條件(jian)要(yao)求設計定(ding)做。

電(dian)(dian)動(dong)(dong)(dong)推(tui)桿(gan)(gan)可(ke)(ke)以根據不(bu)同的(de)(de)(de)應用(yong)(yong)負荷(he)而設(she)(she)計(ji)不(bu)同推(tui)力的(de)(de)(de)電(dian)(dian)動(dong)(dong)(dong)推(tui)桿(gan)(gan)，一般(ban)其最大(da)推(tui)力可(ke)(ke)達6000N，空(kong)載運行速度為4mm~35mm/s，電(dian)(dian)動(dong)(dong)(dong)推(tui)桿(gan)(gan)以24V/12V直(zhi)流永磁電(dian)(dian)機(ji)(ji)(ji)為動(dong)(dong)(dong)力源，把電(dian)(dian)機(ji)(ji)(ji)的(de)(de)(de)旋轉運動(dong)(dong)(dong)轉化為直(zhi)線往復運動(dong)(dong)(dong)，推(tui)動(dong)(dong)(dong)一組連桿(gan)(gan)機(ji)(ji)(ji)構(gou)來完成風門、閥(fa)門、閘(zha)門、擋板等切換工(gong)(gong)作。采用(yong)(yong)電(dian)(dian)動(dong)(dong)(dong)推(tui)桿(gan)(gan)作為執(zhi)行機(ji)(ji)(ji)構(gou)不(bu)僅可(ke)(ke)減(jian)少(shao)采用(yong)(yong)氣(qi)(qi)動(dong)(dong)(dong)執(zhi)行機(ji)(ji)(ji)構(gou)所(suo)需的(de)(de)(de)氣(qi)(qi)源裝(zhuang)置和輔助設(she)(she)備，也可(ke)(ke)減(jian)少(shao)執(zhi)行機(ji)(ji)(ji)構(gou)的(de)(de)(de)重(zhong)量(liang)(liang)。氣(qi)(qi)動(dong)(dong)(dong)執(zhi)行機(ji)(ji)(ji)構(gou)在整個控制運行過程中(zhong)都需要(yao)(yao)有一定的(de)(de)(de)氣(qi)(qi)壓，雖(sui)然可(ke)(ke)采用(yong)(yong)消耗量(liang)(liang)小的(de)(de)(de)放大(da)器等，但日積月(yue)累，耗氣(qi)(qi)量(liang)(liang)仍是巨大(da)的(de)(de)(de)。采用(yong)(yong)電(dian)(dian)動(dong)(dong)(dong)推(tui)桿(gan)(gan)執(zhi)行機(ji)(ji)(ji)構(gou)，在改(gai)變控制開度時，需要(yao)(yao)供電(dian)(dian)，在達到所(suo)需開度時就可(ke)(ke)不(bu)再供電(dian)(dian)，因此從節能看，電(dian)(dian)動(dong)(dong)(dong)推(tui)桿(gan)(gan)執(zhi)行機(ji)(ji)(ji)構(gou)比氣(qi)(qi)動(dong)(dong)(dong)執(zhi)行機(ji)(ji)(ji)構(gou)有明(ming)顯節能優(you)點(dian)。適(shi)用(yong)(yong)于遠距離操(cao)縱而廣泛(fan)用(yong)(yong)于電(dian)(dian)力、化工(gong)(gong)、冶(ye)金、礦(kuang)山、輕工(gong)(gong)、交通、船(chuan)舶等部門的(de)(de)(de)風門、閥(fa)門、閘(zha)門等機(ji)(ji)(ji)構(gou)的(de)(de)(de)啟閉、物料裝(zhuang)卸、流量(liang)(liang)控制等，現已(yi)被越來越多的(de)(de)(de)部門用(yong)(yong)它來代替(ti)機(ji)(ji)(ji)構(gou)手、液(ye)壓閥(fa)、減(jian)速傳動(dong)(dong)(dong)機(ji)(ji)(ji)構(gou)的(de)(de)(de)自動(dong)(dong)(dong)裝(zhuang)置。
