一、蘇貝智能調節型部分回轉防爆電動裝置結構原理：

1、組成部分編輯

MW系列角行程調(diao)節電動執行機構由動力(li)部(bu)件(jian)和位(wei)置定位(wei)器(qi)(qi)（PM-2控制(zhi)(zhi)(zhi)板）兩大(da)部(bu)分(fen)組成。其(qi)中(zhong)動力(li)部(bu)件(jian)主要由電動機、減速器(qi)(qi)、力(li)矩行程限制(zhi)(zhi)(zhi)器(qi)(qi)、開關控制(zhi)(zhi)(zhi)箱、手輪和機械限位(wei)裝置以及位(wei)置發(fa)送(song)器(qi)(qi)等組成，其(qi)各(ge)部(bu)分(fen)作用簡述如下：

2、電動機

電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)是特種單(dan)相或三(san)相交流(liu)異步電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)，具有(you)高(gao)啟(qi)動(dong)(dong)(dong)力矩(ju)、低啟(qi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)流(liu)和較小的轉動(dong)(dong)(dong)慣量，因(yin)而有(you)較好的伺服特性。在電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)定(ding)子(zi)內部裝有(you)熱(re)敏開關(guan)(guan)（詳見圖3所示）做過熱(re)保(bao)護，當電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)出現(xian)異常過熱(re)（內部溫(wen)度(du)超過130℃）時該開關(guan)(guan)將(jiang)控制電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)的電(dian)(dian)(dian)(dian)路斷開以(yi)保(bao)護電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)和執(zhi)行(xing)機(ji)(ji)構，當電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)冷卻以(yi)后(hou)開關(guan)(guan)恢復接通(tong)，電(dian)(dian)(dian)(dian)路恢復工作。為了克服慣性惰走，調節(jie)型電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)執(zhi)行(xing)機(ji)(ji)構的電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)機(ji)(ji)控制電(dian)(dian)(dian)(dian)路均有(you)電(dian)(dian)(dian)(dian)制動(dong)(dong)(dong)功(gong)能。

二、蘇貝智能調節型部分回轉防爆電動裝置特點：
1.該裝置防塵、防雨、防輕腐蝕、其防護等X為IP55（特殊訂貨IP65、IP67）。
2.轉矩控制機構動作可靠、調節方便、轉矩重復精度高。
3.采用閥門電動裝置三相異步電機，起動轉矩大、轉動慣性小、使用壽命長等特點，FX絕緣。
4.工作制為短時10分鐘（特殊訂貨30分鐘）。
5.配有機械式（常規型）或液晶（常規型無）閥位指示器，可直觀知道閥門的開度大小。
6.手電動切換：全自動切換，需手動時直接轉運手輪即可操作電動裝置；需電動時直接電動操作，沒有切換手柄的操作。（注意：電動運行時請勿轉運手輪！）
7.有行程限位、過力矩限位和機械限位開關等三重保護，保障了驅動裝置和閥門的使用安全。
8.供電電源：常規為380V（±10％），50Hz（特殊訂貨三相660V、415V、單相220V、60Hz）.
9.防爆標志：ExdIIBT4（常規型不防爆）。
10.環境相對濕度：≤95％（25℃時）。
11.環境溫度(du)：-20~+60℃（特殊(shu)訂貨-40~+100℃）。
