電動推桿已廣(guang)泛(fan)應(ying)用(yong)于(yu)生(sheng)活、生(sheng)產領域，發展(zhan)前景十分寬闊(kuo)。接下來，我們從幾個(ge)方面(mian)(mian)來說明(ming)電(dian)(dian)(dian)推(tui)技術(shu)發展(zhan)對人(ren)類的好處(chu)。根據(ju)電(dian)(dian)(dian)動(dong)推(tui)桿(gan)(gan)(gan)(gan)，可(ke)制造出一款電(dian)(dian)(dian)動(dong)沙(sha)發，與電(dian)(dian)(dian)機一起按(an)摩疲憊的身(shen)體(ti)。電(dian)(dian)(dian)動(dong)沙(sha)發的使(shi)(shi)用(yong)也充分體(ti)現了(le)舒(shu)適度(du)(du)。電(dian)(dian)(dian)扶梯的高度(du)(du)和傾角一般(ban)都可(ke)以用(yong)電(dian)(dian)(dian)動(dong)推(tui)桿(gan)(gan)(gan)(gan)來調(diao)(diao)整，主(zhu)要是用(yong)電(dian)(dian)(dian)動(dong)推(tui)桿(gan)(gan)(gan)(gan)，又稱直線(xian)(xian)(xian)擺桿(gan)(gan)(gan)(gan)，線(xian)(xian)(xian)性驅動(dong)。線(xian)(xian)(xian)型電(dian)(dian)(dian)動(dong)推(tui)桿(gan)(gan)(gan)(gan)是一種(zhong)把旋轉運(yun)動(dong)轉換成直線(xian)(xian)(xian)運(yun)動(dong)的工業設備(bei)(bei)。可(ke)根據(ju)配對電(dian)(dian)(dian)機、絲桿(gan)(gan)(gan)(gan)、控(kong)制、限位開關等不同組合，完成調(diao)(diao)節(jie)、傾斜、旋轉等功能(neng)(neng)。使(shi)(shi)用(yong)電(dian)(dian)(dian)動(dong)推(tui)桿(gan)(gan)(gan)(gan)執行器(qi)時，改變控(kong)制開度(du)(du)必(bi)須功率，而且當達到(dao)要求的開度(du)(du)時，就不能(neng)(neng)提供(gong)更多(duo)電(dian)(dian)(dian)力。因(yin)此(ci)，從節(jie)能(neng)(neng)的觀點來看(kan)，與氣(qi)動(dong)執行裝(zhuang)置相比(bi)，電(dian)(dian)(dian)動(dong)推(tui)動(dong)機構(gou)在節(jie)能(neng)(neng)層面(mian)(mian)具有明(ming)顯的優點。選用(yong)電(dian)(dian)(dian)動(dong)推(tui)桿(gan)(gan)(gan)(gan)作(zuo)致動(dong)器(qi)，不但(dan)可(ke)減少氣(qi)動(dong)執行機構(gou)所(suo)需的氣(qi)源(yuan)、輔助設備(bei)(bei)，并且可(ke)緩解執行器(qi)的重量。

當前(qian)，為(wei)了(le)方(fang)(fang)(fang)便用戶使(shi)用和(he)操作(zuo)，在電(dian)(dian)(dian)(dian)(dian)動(dong)液(ye)(ye)壓(ya)推(tui)桿(gan)產品的(de)(de)(de)(de)設(she)計中(zhong)，一(yi)般都(dou)會設(she)定多種(zhong)速(su)(su)(su)(su)度(du)(du)控(kong)制(zhi)方(fang)(fang)(fang)法(fa)。其中(zhong)大部分(fen)(fen)是由(you)電(dian)(dian)(dian)(dian)(dian)調速(su)(su)(su)(su)器來(lai)(lai)實(shi)(shi)現(xian)(xian)的(de)(de)(de)(de)。換言之，電(dian)(dian)(dian)(dian)(dian)液(ye)(ye)推(tui)桿(gan)有(you)不(bu)(bu)(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)(de)速(su)(su)(su)(su)度(du)(du)控(kong)制(zhi)方(fang)(fang)(fang)法(fa)，主要是由(you)于采用的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)機(ji)類(lei)(lei)型不(bu)(bu)(bu)(bu)同(tong)(tong)(tong)。對使(shi)用者(zhe)來(lai)(lai)講，經(jing)常(chang)必須(xu)根(gen)據(ju)不(bu)(bu)(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)(de)工(gong)作(zuo)標準，對電(dian)(dian)(dian)(dian)(dian)液(ye)(ye)推(tui)桿(gan)開展適當調整。那樣，就可以通過磁場(chang)對電(dian)(dian)(dian)(dian)(dian)力的(de)(de)(de)(de)作(zuo)用，使(shi)電(dian)(dian)(dian)(dian)(dian)限(xian)速(su)(su)(su)(su)器的(de)(de)(de)(de)功率(lv)隨其自身速(su)(su)(su)(su)度(du)(du)轉變(bian)。運用這種(zhong)方(fang)(fang)(fang)法(fa)，能通過控(kong)制(zhi)擺桿(gan)的(de)(de)(de)(de)速(su)(su)(su)(su)度(du)(du)來(lai)(lai)控(kong)制(zhi)推(tui)桿(gan)的(de)(de)(de)(de)輸入功率(lv)，從(cong)而實(shi)(shi)現(xian)(xian)速(su)(su)(su)(su)度(du)(du)控(kong)制(zhi)。很明顯，假如(ru)電(dian)(dian)(dian)(dian)(dian)液(ye)(ye)推(tui)桿(gan)配備不(bu)(bu)(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)動(dong)調速(su)(su)(su)(su)器，可實(shi)(shi)現(xian)(xian)的(de)(de)(de)(de)實(shi)(shi)際控(kong)制(zhi)方(fang)(fang)(fang)式(shi)也是不(bu)(bu)(bu)(bu)同(tong)(tong)(tong)的(de)(de)(de)(de)。若從(cong)構造(zao)、工(gong)作(zuo)原理、電(dian)(dian)(dian)(dian)(dian)源(yuan)方(fang)(fang)(fang)法(fa)等方(fang)(fang)(fang)面(mian)進行差別，可以分(fen)(fen)為(wei)防爆電(dian)(dian)(dian)(dian)(dian)推(tui)、直(zhi)流式(shi)、交流式(shi)、步進式(shi)、永(yong)磁電(dian)(dian)(dian)(dian)(dian)磁同(tong)(tong)(tong)步、三(san)相異步感應(ying)(ying)等。實(shi)(shi)際上，根(gen)據(ju)實(shi)(shi)際應(ying)(ying)用情(qing)況，在電(dian)(dian)(dian)(dian)(dian)液(ye)(ye)推(tui)桿(gan)產品中(zhong)，較為(wei)了(le)基于不(bu)(bu)(bu)(bu)同(tong)(tong)(tong)工(gong)作(zuo)功率(lv)的(de)(de)(de)(de)單相電(dian)(dian)(dian)(dian)(dian)調速(su)(su)(su)(su)器和(he)三(san)相電(dian)(dian)(dian)(dian)(dian)調速(su)(su)(su)(su)器。該電(dian)(dian)(dian)(dian)(dian)控(kong)設(she)備按維護方(fang)(fang)(fang)式(shi)可分(fen)(fen)為(wei)1級(ji)、2級(ji)和(he)3級(ji)三(san)種(zhong)。除(chu)以上分(fen)(fen)類(lei)(lei)法(fa)外，其工(gong)作(zuo)速(su)(su)(su)(su)度(du)(du)及(ji)阻燃等級(ji)可作(zuo)為(wei)液(ye)(ye)壓(ya)推(tui)桿(gan)式(shi)電(dian)(dian)(dian)(dian)(dian)沖壓(ya)機(ji)產品類(lei)(lei)別的(de)(de)(de)(de)依據(ju)。電(dian)(dian)(dian)(dian)(dian)機(ji)可分(fen)(fen)為(wei)定速(su)(su)(su)(su)電(dian)(dian)(dian)(dian)(dian)機(ji)、高速(su)(su)(su)(su)電(dian)(dian)(dian)(dian)(dian)機(ji)、低(di)速(su)(su)(su)(su)電(dian)(dian)(dian)(dian)(dian)機(ji)和(he)變(bian)速(su)(su)(su)(su)電(dian)(dian)(dian)(dian)(dian)機(ji)。調速(su)(su)(su)(su)電(dian)(dian)(dian)(dian)(dian)機(ji)；后者(zhe)可以分(fen)(fen)為(wei)部分(fen)(fen)絕緣、全絕緣和(he)半絕緣型。
