DZW30-18電動執行器安裝及拆卸注意事項：

1、DZW調節(jie)型(xing)電動執行器的安裝(zhuang)形式無原則要(yao)求，但電機(ji)處于水平(ping)狀態(tai)，電氣箱蓋處于水平(ping)或垂直向上狀態(tai)為推薦安裝(zhuang)形式，這(zhe)樣有利于潤(run)滑(hua)、調試、維護和手動操作(zuo)；

2、安裝(zhuang)時應保證維(wei)修檢查人員拆卸各(ge)部件(jian)所需的(de)空間；

3、安(an)裝(zhuang)與閥門連(lian)接的(de)牙嵌軸向間隙不少于1~2mm；

4、與閥(fa)門(men)連接的螺栓不得低(di)于8.8級；

5、當(dang)用于明桿閥(fa)門時，應檢(jian)查閥(fa)桿伸出量與(yu)閥(fa)桿護套的(de)長(chang)度是否相符；

6、當需要(yao)拆卸時，應先將手動手輪旋(xuan)轉(zhuan)數圈(quan)，在閥門稍開(kai)狀(zhuang)態下進(jin)行；

7、安(an)裝、拆卸、調試(shi)時不可損傷密封面(mian)、密封件和防(fang)爆(bao)(bao)型電裝的防(fang)爆(bao)(bao)面(mian)，并應(ying)(ying)在隔爆(bao)(bao)面(mian)上(shang)涂防(fang)銹油，電氣罩(zhao)蓋(gai)應(ying)(ying)蓋(gai)嚴緊固，以防(fang)雨水(shui)或潮氣進入；

8、視窗不得(de)與硬物碰撞(zhuang)；

9、本(ben)電(dian)動裝置為短時(shi)(shi)工作(zuo)制，持續工作(zuo)時(shi)(shi)間不得超過銘(ming)牌標定時(shi)(shi)間；

10、閥門不(bu)(bu)經常使用時(shi)，應定期檢查保養并(bing)操作運行，建議每(mei)月***一次，運行時(shi)間不(bu)(bu)超過10分鐘。

電(dian)力(li)電(dian)子(zi)技術、計(ji)算機技術及通訊技術的(de)(de)快速(su)發展必將(jiang)(jiang)推動電(dian)動執行器更加(jia)快速(su)的(de)(de)發展，機電(dian)一體化將(jiang)(jiang)取代(dai)(dai)分體式結構;智(zhi)能(neng)通訊的(de)(de)取代(dai)(dai)模擬的(de)(de);控制精度將(jiang)(jiang)越來越高，使(shi)用(yong)環境越來越廣;功能(neng)更強大，可靠性更高，以適應不斷發展的(de)(de)自(zi)動控制的(de)(de)要(yao)求。

閥門電動執行器是指在控制系統中以電為能源的(de)一種執行器，接(jie)受(shou)調(diao)節(jie)儀表等(deng)的(de)電信(xin)號(hao)，根據信(xin)號(hao)的(de)大(da)小改(gai)變(bian)(bian)操縱量(liang)，使輸入或(huo)輸出控制對象(xiang)的(de)物料(liao)量(liang)或(huo)能量(liang)改(gai)變(bian)(bian)，達到自動調(diao)節(jie)目(mu)的(de)。在工(gong)業生產中，電動調(diao)節(jie)閥應用(yong)廣(guang)泛。電動調(diao)節(jie)閥是由執行機構(gou)和(he)調(diao)節(jie)機構(gou)（閥）兩部分構(gou)成。
