DZWZ20I智能一(yi)體化(hua)電動執行器特點：

1、主要參數(shu)技(ji)術指(zhi)(zhi)標，如工(gong)作死區、基本誤差(cha)、回差(cha)等指(zhi)(zhi)標已達到或接(jie)近世界水平(ping)，超過國內現有DDZ一Ⅱ、Ⅲ型電動(dong)執行(xing)器。

2、采用(yong)微(wei)機和數(shu)字(zi)顯示(shi)(shi)技術，以智能(neng)伺服放大器(qi)取(qu)代傳(chuan)統伺服放大器(qi)，以數(shu)字(zi)式(shi)操(cao)作器(qi)取(qu)代原有模擬指針式(shi)操(cao)作器(qi)，解(jie)決了數(shu)字(zi)顯示(shi)(shi)跳(tiao)動頻繁而造成人眼疲勞的問題。

3、功(gong)能(neng)強、使用方(fang)便，具有自(zi)(zi)診斷、自(zi)(zi)調整(zheng)和PI調節等功(gong)能(neng)，尤其是(shi)PI調節功(gong)能(neng)可省去(qu)前級調節器(qi)，直(zhi)接接受變送器(qi)信(xin)號。

4、增加了流(liu)(liu)量特(te)(te)(te)(te)性(xing)(xing)(xing)軟件修(xiu)(xiu)正(zheng)(zheng)。采用微處理機后(hou)，能(neng)靈活地設定(ding)、改(gai)變(bian)流(liu)(liu)量特(te)(te)(te)(te)性(xing)(xing)(xing)，提高調節閥(fa)控制(zhi)性(xing)(xing)(xing)能(neng)，使(shi)一種固有(you)特(te)(te)(te)(te)性(xing)(xing)(xing)的調節閥(fa)可以擁有(you)多種輸出特(te)(te)(te)(te)性(xing)(xing)(xing)，使(shi)不能(neng)進(jin)行(xing)閥(fa)芯形狀修(xiu)(xiu)正(zheng)(zheng)(蝶(die)閥(fa))的閥(fa)也可改(gai)變(bian)流(liu)(liu)量特(te)(te)(te)(te)性(xing)(xing)(xing)，可以使(shi)非(fei)標準特(te)(te)(te)(te)性(xing)(xing)(xing)修(xiu)(xiu)正(zheng)(zheng)為標準特(te)(te)(te)(te)性(xing)(xing)(xing)，該(gai)功(gong)能(neng)將改(gai)變(bian)長(chang)期(qi)以來靠閥(fa)芯加工修(xiu)(xiu)正(zheng)(zheng)流(liu)(liu)量特(te)(te)(te)(te)性(xing)(xing)(xing)的現狀。

5、在調(diao)節(jie)中(zhong)采用電制動(dong)和斷續(xu)調(diao)節(jie)技術，對具有自(zi)鎖功能的執行機構(gou)可(ke)取消機械摩(mo)擦制動(dong)器，提高了整機的可(ke)靠(kao)性。

6、三相(xiang)放大器(qi)的設計采用有(you)單相(xiang)智能伺(si)服放大器(qi)外接三相(xiang)功(gong)率轉換器(qi)的組合(he)式(shi)方案(an)，方便(bian)了生(sheng)產和備(bei)料(liao)，為(wei)控制室不進三相(xiang)電源的控制提供了可能。

用途(tu)：

可通過遠程控(kong)(kong)制、現(xian)場(chang)控(kong)(kong)制兩種控(kong)(kong)制方式，對風門(men)實現(xian)開啟、關閉與調節。智能一體(ti)(ti)化(hua)風門(men)電動執行(xing)機構(gou)具有控(kong)(kong)制原理先(xian)進(jin)、功能全(quan)面、長期(qi)穩定(ding)可靠、集成度(du)高、發熱量小、裝卸方便、維護(hu)簡單(dan)等特點，并可通過紅(hong)外遙(yao)控(kong)(kong)器對其進(jin)行(xing)非侵(qin)入式的快速設置，采用全(quan)視角LCD段碼(ma)液晶顯示器，閥(fa)門(men)的支行(xing)參數、工作狀態可清晰直觀(guan)的進(jin)行(xing)現(xian)場(chang)監控(kong)(kong)。
