電動(dòng)推桿，英文名稱(chēng)為L(zhǎng)inearActuator，又叫推桿電機(jī)、電動(dòng)缸及線性致動(dòng)器。電動(dòng)推桿是一種將電動(dòng)機(jī)的旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)變?yōu)橥茥U的直線往復(fù)運(yùn)動(dòng)的電力驅(qū)動(dòng)裝置?？捎糜诟鞣N簡(jiǎn)單或者復(fù)雜的工藝流程中做為執(zhí)行機(jī)械使用，以達(dá)到遠(yuǎn)距離控制、集中控制或自動(dòng)控制的目的。電動(dòng)推桿是一種新型的電動(dòng)執(zhí)行機(jī)構(gòu)，它主要是一類(lèi)由驅(qū)動(dòng)電機(jī)、減速齒輪、螺桿、螺母、導(dǎo)套、推桿、滑座、彈簧、外殼及渦輪、微動(dòng)控制開(kāi)關(guān)等機(jī)構(gòu)組成的一種新型直線執(zhí)行機(jī)構(gòu)，可以實(shí)現(xiàn)遠(yuǎn)距離控制、集中控制。電動(dòng)推桿是一種將電動(dòng)機(jī)的旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)變?yōu)橥茥U的直線往復(fù)運(yùn)動(dòng)的電力驅(qū)動(dòng)裝置,其原理是：電動(dòng)機(jī)經(jīng)齒輪減速后，帶動(dòng)一對(duì)絲桿螺母，把電機(jī)的旋轉(zhuǎn)運(yùn)動(dòng)變成直線運(yùn)動(dòng)，陜西DGR電動(dòng)缸的用途和特點(diǎn)，通過(guò)利用電動(dòng)機(jī)正反轉(zhuǎn)完成推桿動(dòng)作，如通過(guò)各種杠桿、搖桿或連桿等機(jī)構(gòu)可完成轉(zhuǎn)動(dòng)、搖動(dòng)等復(fù)雜動(dòng)作，通過(guò)改變杠桿力臂長(zhǎng)度，可以增大或加大行程。電動(dòng)推桿是通用型的輔助驅(qū)動(dòng)裝置，可以被廣泛應(yīng)用在電力、機(jī)械、冶金、交通、礦山、石油、化工、起重、運(yùn)輸，陜西DGR電動(dòng)缸的用途和特點(diǎn)、建筑以及糧飼加工等行業(yè)，這主要是因?yàn)樗哂行阅芸煽?，?dòng)作靈敏，陜西DGR電動(dòng)缸的用途和特點(diǎn)，運(yùn)行平穩(wěn)，推拉力相同以及對(duì)環(huán)境的良好適應(yīng)性能等諸多優(yōu)點(diǎn)。

匯率結(jié)算風(fēng)險(xiǎn)，又稱(chēng)匯率交易風(fēng)險(xiǎn)，是一般企業(yè)以外幣計(jì)價(jià)進(jìn)行貿(mào)易及非貿(mào)易交易時(shí)，因?qū)?lái)結(jié)算時(shí)所適用的外匯匯率未確定而產(chǎn)生的匯率風(fēng)險(xiǎn)。 </p> <p> <br /> </p> <p> 企業(yè)在從事貿(mào)易及非貿(mào)易業(yè)務(wù)的過(guò)程中，從雙方達(dá)成協(xié)議，到結(jié)清債權(quán)債務(wù)，一般需要幾個(gè)月甚至1年或更長(zhǎng)的時(shí)間，而在此期間，若計(jì)價(jià)貨幣匯率發(fā)生變動(dòng)，必將使交易雙方中的某一方蒙受損失，這便產(chǎn)生了匯率結(jié)算風(fēng)險(xiǎn)。例如，美國(guó)某企業(yè)從日本進(jìn)口一批機(jī)械設(shè)備。雙方于某年3月1日簽約，約定以日元計(jì)價(jià)，貨款為l400萬(wàn)日元，支付日期為同年6月1日。假定3月1日美元與日元的匯率為l美元=140日元，則美國(guó)需要支付10萬(wàn)美元購(gòu)買(mǎi)l400萬(wàn)日元。
