style="text-indent:25px">電動執(zhí)行器、電動執(zhí)行機構又稱閥門電動裝置，它是在不同行業(yè)領域的稱謂，在工業(yè)管道閥門行業(yè)稱之為閥門電動裝置，在儀表行業(yè)稱之為電動執(zhí)行器，但現(xiàn)在業(yè)內(nèi)已沒有很明確的區(qū)分，本文所涉及到的關于稱謂問題將統(tǒng)一稱之為電動執(zhí)行器。閥門在工業(yè)管路控制中是經(jīng)常使用的重要設備，電動閥門（電動執(zhí)行機構）隨著工業(yè)自動化的發(fā)展，因其動力源容易取得，且一般情況下無需維護的優(yōu)點，比起氣動、液動等不同驅動方式的設備使用更為普遍。在工業(yè)場合電動閥門必需具有更高的可靠性和安全性，當閥門能保證性能和壽命的情況下，電動閥門的安全性與可靠性取決于電動執(zhí)行器，因此電動執(zhí)行器的性能、控制水平是電動閥門整機技術水平的綜合表現(xiàn)。所以在電動執(zhí)行器選型時除必需考慮的一些基本要素外，對其提出合理的技術要求才能使電動閥門價值實現(xiàn)好大化。 </p><p style="text-indent:25px">電動單回轉式執(zhí)行機構:這種執(zhí)行機構類似于電動多回轉執(zhí)行機構，主要差別是執(zhí)行機構好終輸出的是1/4轉記90度的運動。新一代電動單回轉式執(zhí)行機構結合了大部分多回轉執(zhí)行機構的復雜功能，例如：使用非進入式用戶友好的操作界面實現(xiàn)參數(shù)設定與診斷功能。單回轉執(zhí)行機構結構緊湊可以安裝到小尺寸閥門上，通常輸出力矩可達800公斤米，另外應為所需電源較小，它們可以安裝電池來實現(xiàn)故障安全操作。動執(zhí)行機構的缺點結構較復雜，更容易發(fā)生故障，且由于它的復雜性，對現(xiàn)場維護人員的技術要求就相對要高一些;電機運行要產(chǎn)生熱，如果調(diào)節(jié)太頻繁，容易造成電機過熱，產(chǎn)生熱保護，同時也會加大對減速齒輪的磨損;另外就是運行較慢，從調(diào)節(jié)器輸出一個信號，到調(diào)節(jié)閥響應而運動到那個相應的位置，需要較長的時間，這是它不如氣動、液動執(zhí)行器的地方。執(zhí)行機構由自動工作系統(tǒng)和各種輔助裝置兩大部分組成。</p><div

style="text-indent:25px">機械限位裝置：主要用于故障時以及防止手動操作時超過極限位置保護。角行程電動執(zhí)行機構的機械限位采用內(nèi)置扇形渦輪限位結構，外形體積小，限位可靠；直行程電動執(zhí)行機構的機械限位采用內(nèi)置擋塊型限位結構，可十分有效地保護閥座、閥桿、閥芯。位置定位器實質上是一個將控制信號與位置反饋信號進行比較并放大以控制電動機開停和旋轉方向的多功能大功率放大板，它與執(zhí)行機構的動力部件相連以控制執(zhí)行機構按系統(tǒng)規(guī)定的狀態(tài)工作。位置定位器主要由比較、邏輯保護、放大驅動及功率放大等電路組成。控制單相電動機的位置定位器功率放大部分主要由光電禍合過零觸發(fā)固態(tài)繼電器（無觸點電子開關）構成。其主體部分示意如圖4所示。需要注意的是“手動一自動”轉換開關，該開關的作用是在沒有外加信號時，與手動調(diào)整電位器P1配合使用，以便觀察或調(diào)試執(zhí)行機構。用后一定要將其撥回“自動”位世，以免影響投人系統(tǒng)自動控制。執(zhí)行機構根據(jù)力矩曲線的變化可以預測出將會發(fā)生的故障，可以對預測性維護提供有價值的信息。蘇州電動執(zhí)行機構價格</p><p style="text-indent:25px">執(zhí)行機構電氣施工比較簡單，施工費用低廉。蘇州電動執(zhí)行機構價格</p><p style="text-indent:25px">優(yōu)點:電動執(zhí)行機構的主要優(yōu)點就是高度的穩(wěn)定和用戶可應用的恒定的推力，好大執(zhí)行器產(chǎn)生的推力可高達225000kgf，能達到這么大推力的只有液動執(zhí)行器，但液動執(zhí)行器造價要比電動高很多。電動執(zhí)行器的抗偏離能力是很好的，輸出的推力或力矩基本上是恒定的，可以很好的克服介質的不平衡力，達到對工藝參數(shù)的準確控制，所以控制精度比氣動執(zhí)行器要高。如果配用伺服放大器，可以很容易地實現(xiàn)正反作用的互換，也可以輕松設定斷信號閥位狀態(tài)(保持/全開/全關)，而故障時，一定停留在原位，這是氣動執(zhí)行器所作不到，氣動執(zhí)行器必須借助于一套組合保護系統(tǒng)來實現(xiàn)保位。蘇州電動執(zhí)行機構價格</p></p><br
