Z20-24W-WK智能一體化電動執行器

手、電動(dong)切換機(ji)構：

Z20-24W-WK閥(fa)門電動裝(zhuang)置為(wei)半自(zi)動(dong)(dong)(dong)(dong)切換(huan)，手(shou)(shou)動(dong)(dong)(dong)(dong)時需扳手(shou)(shou)柄(bing)切換(huan)，手(shou)(shou)動(dong)(dong)(dong)(dong)狀(zhuang)(zhuang)態轉(zhuan)變(bian)為(wei)電動(dong)(dong)(dong)(dong)時則自(zi)動(dong)(dong)(dong)(dong)運行。它由(you)手(shou)(shou)柄(bing)、切換(huan)件、直(zhi)立(li)桿(gan)、離(li)(li)(li)(li)合(he)(he)器(qi)、壓(ya)(ya)簧等組(zu)成(cheng)。需手(shou)(shou)輪(lun)(lun)操作(zuo)時，將手(shou)(shou)柄(bing)向(xiang)(xiang)手(shou)(shou)動(dong)(dong)(dong)(dong)方向(xiang)(xiang)推動(dong)(dong)(dong)(dong)，切換(huan)件使(shi)離(li)(li)(li)(li)合(he)(he)器(qi)抬(tai)高，并(bing)壓(ya)(ya)迫壓(ya)(ya)簧。當(dang)手(shou)(shou)柄(bing)推到一定(ding)位置時，離(li)(li)(li)(li)合(he)(he)器(qi)即(ji)(ji)脫(tuo)離(li)(li)(li)(li)蝸輪(lun)(lun)而(er)與(yu)手(shou)(shou)輪(lun)(lun)嚙(nie)合(he)(he)，同時直(zhi)立(li)桿(gan)在扭簧作(zuo)用(yong)下(xia)直(zhi)立(li)于蝸輪(lun)(lun)端(duan)(duan)面，支撐住離(li)(li)(li)(li)合(he)(he)器(qi)不致下(xia)落，切換(huan)完成(cheng)即(ji)(ji)可放(fang)開手(shou)(shou)柄(bing)，使(shi)用(yong)托(tuo)辦(ban)進行操作(zuo)。而(er)需電動(dong)(dong)(dong)(dong)操作(zuo)時，電動(dong)(dong)(dong)(dong)機將帶(dai)動(dong)(dong)(dong)(dong)蝸輪(lun)(lun)轉(zhuan)動(dong)(dong)(dong)(dong)，支承于蝸輪(lun)(lun)端(duan)(duan)面的直(zhi)立(li)桿(gan)即(ji)(ji)倒下(xia)，在壓(ya)(ya)簧作(zuo)用(yong)下(xia)離(li)(li)(li)(li)合(he)(he)器(qi)迅速向(xiang)(xiang)蝸輪(lun)(lun)方向(xiang)(xiang)移(yi)動(dong)(dong)(dong)(dong)，并(bing)與(yu)蝸輪(lun)(lun)嚙(nie)合(he)(he)，同時與(yu)手(shou)(shou)輪(lun)(lun)脫(tuo)開，自(zi)動(dong)(dong)(dong)(dong)實現(xian)手(shou)(shou)動(dong)(dong)(dong)(dong)到電動(dong)(dong)(dong)(dong)狀(zhuang)(zhuang)態的轉(zhuan)換(huan)。

Z20-24W-WK智能一體化電動執行器

近年(nian)來(lai)，電(dian)動(dong)執(zhi)行(xing)(xing)(xing)機構獲得了快速發展，國(guo)內外(wai)一些廠商相繼(ji)推出帶現(xian)(xian)(xian)場(chang)總線(xian)通(tong)信(xin)(xin)協(xie)議的智能(neng)電(dian)動(dong)執(zhi)行(xing)(xing)(xing)器。新型智能(neng)電(dian)動(dong)執(zhi)行(xing)(xing)(xing)器利用微機和(he)現(xian)(xian)(xian)場(chang)總線(xian)通(tong)信(xin)(xin)技術將伺服放大器與執(zhi)行(xing)(xing)(xing)機構合為一體，不僅實(shi)現(xian)(xian)(xian)了雙向通(tong)信(xin)(xin)、PID調節、在線(xian)自動(dong)標(biao)定、自校正(zheng)與自診斷(duan)等多種控(kong)制(zhi)技術要求的功能(neng)，還增設了行(xing)(xing)(xing)程保護、過力矩(ju)保護、電(dian)動(dong)機過熱(re)保護、斷(duan)電(dian)信(xin)(xin)號保護、輸出現(xian)(xian)(xian)場(chang)閥位指示和(he)故障報(bao)警等功能(neng)。它可進行(xing)(xing)(xing)現(xian)(xian)(xian)場(chang)操作(zuo)(zuo)或遠(yuan)方操作(zuo)(zuo)，完成手(shou)動(dong)操作(zuo)(zuo)及手(shou)動(dong)／自動(dong)之間無擾動(dong)切換。
