電動推(tui)(tui)桿由(you)驅動電機、減(jian)速齒輪、螺桿、螺母、導套、推(tui)(tui)桿、滑座、彈簧、外殼及渦輪、微動控制(zhi)開關等組成。

電(dian)動推桿(gan)是(shi)一種(zhong)新型(xing)(xing)的電(dian)動執行機構，電(dian)動推桿(gan)主要由電(dian)機、推桿(gan)和(he)控(kong)(kong)制(zhi)裝置等(deng)機構組成的一種(zhong)新型(xing)(xing)直(zhi)線執行機構，可以實現遠距(ju)離控(kong)(kong)制(zhi)、集中控(kong)(kong)制(zhi)。電(dian)動推桿(gan)在一定范圍(wei)行程(cheng)內(nei)作往返(fan)運動，一般(ban)電(dian)動推桿(gan)標準行程(cheng)在，100，150，200，250，300，350，400mm，特殊行程(cheng)也(ye)可根據不(bu)同(tong)應用條件要求設計定做。

電(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)(gan)(gan)可(ke)(ke)以根據不(bu)同的應用(yong)負荷而(er)設計不(bu)同推(tui)(tui)力的電(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)(gan)(gan)，一(yi)般其最大推(tui)(tui)力可(ke)(ke)達(da)6000N，空(kong)載運(yun)行(xing)(xing)速(su)(su)度為(wei)(wei)4mm~35mm/s，電(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)(gan)(gan)以24V/12V直流永磁電(dian)(dian)機(ji)為(wei)(wei)動(dong)(dong)力源，把電(dian)(dian)機(ji)的旋轉運(yun)動(dong)(dong)轉化(hua)為(wei)(wei)直線往(wang)復運(yun)動(dong)(dong)，推(tui)(tui)動(dong)(dong)一(yi)組連桿(gan)(gan)(gan)機(ji)構(gou)(gou)來完成風(feng)(feng)門(men)(men)(men)、閥門(men)(men)(men)、閘門(men)(men)(men)、擋板等(deng)(deng)切換工(gong)作。采(cai)用(yong)電(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)(gan)(gan)作為(wei)(wei)執行(xing)(xing)機(ji)構(gou)(gou)不(bu)僅可(ke)(ke)減少采(cai)用(yong)氣動(dong)(dong)執行(xing)(xing)機(ji)構(gou)(gou)所需(xu)(xu)的氣源裝置和輔助(zhu)設備，也可(ke)(ke)減少執行(xing)(xing)機(ji)構(gou)(gou)的重量。氣動(dong)(dong)執行(xing)(xing)機(ji)構(gou)(gou)在整(zheng)個控(kong)制(zhi)(zhi)運(yun)行(xing)(xing)過程(cheng)中都(dou)需(xu)(xu)要有(you)(you)一(yi)定的氣壓，雖然可(ke)(ke)采(cai)用(yong)消耗量小的放大器等(deng)(deng)，但日積(ji)月累(lei)，耗氣量仍是(shi)巨大的。采(cai)用(yong)電(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)(gan)(gan)執行(xing)(xing)機(ji)構(gou)(gou)，在改變控(kong)制(zhi)(zhi)開度時(shi)，需(xu)(xu)要供電(dian)(dian)，在達(da)到所需(xu)(xu)開度時(shi)就可(ke)(ke)不(bu)再供電(dian)(dian)，因此從節能(neng)看，電(dian)(dian)動(dong)(dong)推(tui)(tui)桿(gan)(gan)(gan)執行(xing)(xing)機(ji)構(gou)(gou)比(bi)氣動(dong)(dong)執行(xing)(xing)機(ji)構(gou)(gou)有(you)(you)明顯節能(neng)優點。適用(yong)于遠距離操縱(zong)而(er)廣泛用(yong)于電(dian)(dian)力、化(hua)工(gong)、冶金(jin)、礦山(shan)、輕工(gong)、交通、船(chuan)舶等(deng)(deng)部(bu)(bu)門(men)(men)(men)的風(feng)(feng)門(men)(men)(men)、閥門(men)(men)(men)、閘門(men)(men)(men)等(deng)(deng)機(ji)構(gou)(gou)的啟閉、物料裝卸、流量控(kong)制(zhi)(zhi)等(deng)(deng)，現已(yi)被越(yue)來越(yue)多的部(bu)(bu)門(men)(men)(men)用(yong)它來代替機(ji)構(gou)(gou)手、液(ye)壓閥、減速(su)(su)傳(chuan)動(dong)(dong)機(ji)構(gou)(gou)的自(zi)動(dong)(dong)裝置。
