多回轉(zhuan)電(dian)動(dong)執(zhi)行(xing)器(qi)

CNZ多回轉(zhuan)電(dian)動(dong)執(zhi)行(xing)器(qi)，是在引(yin)進國外智(zhi)能電(dian)動(dong)執(zhi)行(xing)機構(gou)的技(ji)術基(ji)礎上，采(cai)用當(dang)今(jin)超(chao)大(da)規模(mo)數字(zi)集成電(dian)路(lu)研制而成的新壹(yi)代(dai)智(zhi)能化、數(shu)字(zi)化、全(quan)中(zhong)文菜單顯(xian)示、遙(yao)控操作的電(dian)動(dong)執(zhi)行(xing)機構(gou)，非(fei)入侵(qin)式設計(ji)：采(cai)用磁感(gan)應控制旋鈕，沒(mei)有穿過控制箱(xiang)的貫通軸；非(fei)接觸(chu)式調試(shi)：采(cai)用紅外(wai)線(xian)遙(yao)控器(qi)對電(dian)動(dong)裝(zhuang)置進行工(gong)作設定，真正地免開蓋(gai)調試(shi)；雙(shuang)密封(feng)結構(gou)： 在安(an)裝(zhuang)調試(shi)階段接線(xian)盒(he)打(da)開(kai)時，電(dian)動(dong)裝(zhuang)置內部(bu)仍(reng)得到很(hen)好的密封(feng)防護。防水(shui)型(xing)設計(ji)使(shi)電(dian)動(dong)裝(zhuang)置能在水(shui)淹(yan)48小時內正(zheng)常工作；
CNZ智(zhi)能型(xing)多回轉(zhuan)電(dian)動(dong)執(zhi)行(xing)器(qi)保(bao)護措施：

1.轉(zhuan)矩保(bao)護： 在額定(ding)轉(zhuan)矩的40%~120%的範圍內可任(ren)意(yi)設(she)定保護轉(zhuan)矩，且(qie)打(da)開(kai)方向和關閉方向的設定保護值可以不(bu)壹(yi)樣(yang)，以保護閥門(men)及(ji)電(dian)動(dong)裝(zhuang)置本(ben)身；
2.閥(fa)位限位保護：當(dang)允(yun)許(xu)該(gai)項(xiang)功(gong)能(neng)時，電(dian)動(dong)裝(zhuang)置運轉(zhuan)到設(she)定(ding)的閥位極(ji)***自(zi)動(dong)停(ting)止運轉(zhuan)；
3.電(dian)源缺(que)相保(bao)護：在運行過程中(zhong)實時檢測動(dong)態情況(kuang)下(xia)的電(dian)源缺(que)相，防止電(dian)機缺(que)相運行；
4.電(dian)子閂(shuan)鎖保護：啟(qi)動(dong)信號發出5秒(miao)內，自(zi)動(dong)禁止轉(zhuan)矩保(bao)護功(gong)能(neng)，以得到的輸出轉(zhuan)矩打(da)開(kai)卡住的閥門(men)。如在該(gai)時段內仍(reng)不能(neng)使(shi)閥(fa)門(men)動(dong)作，則自動(dong)切(qie)斷(duan)電(dian)機電(dian)源，並報(bao)警(jing)保(bao)護電(dian)動(dong)裝(zhuang)置的電(dian)機；
5.電(dian)機過(guo)熱保護：電(dian)機線(xian)圈(quan)內有二只(zhi)熱繼(ji)電(dian)器(qi)，在電(dian)機過(guo)熱時自動(dong)切(qie)斷(duan)電(dian)機電(dian)源；
6.電(dian)氣保(bao)護： 輸入輸(shu)出(chu)通道均(jun)采(cai)用光(guang)電(dian)隔離；
閥位和轉(zhuan)矩檢(jian)測： 采(cai)用霍爾(er)效應磁脈沖(chong)信(xin)號檢測閥位(wei)及(ji)利(li)用電(dian)機的電(dian)流(liu)磁通來(lai)連續(xu)測定轉(zhuan)矩。*排(pai)除機械磨損(sun)，***；
7.相序自(zi)動(dong)調整(zheng)：自動(dong)檢測接入的三相電(dian)源相序， 並經(jing)邏輯(ji)運算自動(dong)調整(zheng)相序，無需用戶(hu)考慮(lv)三相電(dian)源的接入相序；
