電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)是一種新型(xing)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)執(zhi)(zhi)行機(ji)構(gou)，電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)主(zhu)要由電(dian)(dian)(dian)(dian)(dian)機(ji)、推(tui)(tui)桿(gan)和控制(zhi)裝置(zhi)等機(ji)構(gou)組成的(de)(de)(de)一種新型(xing)直線執(zhi)(zhi)行機(ji)構(gou)，可(ke)以(yi)實現遠(yuan)距離(li)控制(zhi)、集中控制(zhi)。電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)在一定范圍行程內作往返(fan)運動(dong)(dong)，一般電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)標準行程在，100，150，200，250，300，350，400mm，特殊行程也可(ke)根據不同應用條件要求設計定做。電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)，英文名Linear Actuator，又(you)稱推(tui)(tui)桿(gan)電(dian)(dian)(dian)(dian)(dian)機(ji)、電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)缸及(ji)線性致動(dong)(dong)器。電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)是一種將(jiang)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)的(de)(de)(de)旋(xuan)轉運動(dong)(dong)轉變為(wei)推(tui)(tui)桿(gan)的(de)(de)(de)直線往復(fu)運動(dong)(dong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)力(li)驅動(dong)(dong)裝置(zhi)。可(ke)用于各種簡單或(huo)復(fu)雜(za)的(de)(de)(de)工(gong)藝流程中做為(wei)執(zhi)(zhi)行機(ji)械使用，以(yi)實現遠(yuan)距離(li)控制(zhi)、集中控制(zhi)或(huo)自動(dong)(dong)控制(zhi)。

      平行式電動推桿適用于遠距離操縱而廣泛用于電力、化工、冶金、礦山、輕工、交通、船舶等部門的風門、閥門、閘門等機構的啟閉、物料裝卸、流量控制等。現已被越來越多的部門用它來代替機構手、液壓閥、減速傳動機構的自動裝置。

      平行(xing)(xing)式電(dian)(dian)動(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)由驅動(dong)(dong)(dong)(dong)電(dian)(dian)機(ji)(ji)、減(jian)速(su)齒輪(lun)、螺桿(gan)(gan)(gan)、螺母、導套、推(tui)桿(gan)(gan)(gan)、滑座、彈簧(huang)、外殼及(ji)渦(wo)輪(lun)、微動(dong)(dong)(dong)(dong)控(kong)制(zhi)開關(guan)等組成(cheng)。電(dian)(dian)動(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)可(ke)以根(gen)據不(bu)同的(de)(de)(de)應用(yong)負荷而設(she)計不(bu)同推(tui)力的(de)(de)(de)電(dian)(dian)動(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)，一般其 大(da)推(tui)力可(ke)達6000N，空載(zai)運行(xing)(xing)速(su)度(du)(du)為(wei)(wei)(wei)4mm~35mm/s,電(dian)(dian)動(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)以24V/12V 直流(liu)永磁電(dian)(dian)機(ji)(ji)為(wei)(wei)(wei)動(dong)(dong)(dong)(dong)力源，把電(dian)(dian)機(ji)(ji)的(de)(de)(de)旋轉運動(dong)(dong)(dong)(dong)轉化為(wei)(wei)(wei)直線往復運動(dong)(dong)(dong)(dong)。推(tui)動(dong)(dong)(dong)(dong)一組連桿(gan)(gan)(gan)機(ji)(ji)構(gou)來完(wan)成(cheng)風門、閥門、閘(zha)門、擋(dang)板等切換工作。采用(yong)電(dian)(dian)動(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)作為(wei)(wei)(wei)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)構(gou)不(bu)僅可(ke)減(jian)少采用(yong)氣(qi)動(dong)(dong)(dong)(dong)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)構(gou)所需的(de)(de)(de)氣(qi)源裝(zhuang)置(zhi)和輔助設(she)備，也(ye)可(ke)減(jian)少執(zhi)(zhi)行(xing)(xing)機(ji)(ji)構(gou)的(de)(de)(de)重量。氣(qi)動(dong)(dong)(dong)(dong)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)構(gou)在(zai)(zai)整個控(kong)制(zhi)運行(xing)(xing)過程中都(dou)需要有(you)一定(ding)的(de)(de)(de)氣(qi)壓，雖然可(ke)采用(yong)消耗量小(xiao)的(de)(de)(de)放大(da)器等，但日(ri)積月累，耗氣(qi)量仍是巨大(da)的(de)(de)(de)。采用(yong)電(dian)(dian)動(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)構(gou)，在(zai)(zai)改(gai)變控(kong)制(zhi)開度(du)(du)時(shi)(shi)，需要供(gong)電(dian)(dian)，在(zai)(zai)達到所需開度(du)(du)時(shi)(shi) 可(ke)不(bu)再供(gong)電(dian)(dian)，因此(ci)從節能(neng)看，電(dian)(dian)動(dong)(dong)(dong)(dong)推(tui)桿(gan)(gan)(gan)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)構(gou)比氣(qi)動(dong)(dong)(dong)(dong)執(zhi)(zhi)行(xing)(xing)機(ji)(ji)構(gou)有(you)明顯節能(neng)優點(dian)。
