直行程電動執行器設備

江蘇貝爾閥門控制(zhi)有(you)限公司(si)，應用英(ying)國(guo)BAR企(qi)業(ye)頂尖(jian)的英(ying)國(guo)科技，一(yi)直致力(li)于產(chan)品(pin)的研發和創新，運(yun)用智(zhi)能科學管理(li)(li)方法，于中國(guo)開拓(tuo)市(shi)場，擁有(you)先(xian)進技術及管理(li)(li)理(li)(li)念。本公司(si)主要產(chan)品(pin)有(you)：BAR電(dian)動(dong)(dong)(dong)閥門執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)系列、閥門電(dian)動(dong)(dong)(dong)執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)、IOC引(yin)進技術型電(dian)動(dong)(dong)(dong)執(zhi)(zhi)(zhi)行(xing)(xing)機構(gou)、國(guo)產(chan)閥門電(dian)動(dong)(dong)(dong)裝置、BRA精巧型電(dian)動(dong)(dong)(dong)執(zhi)(zhi)(zhi)行(xing)(xing)器(qi)以及各(ge)種電(dian)動(dong)(dong)(dong)閥門、控制(zhi)柜、工業(ye)控制(zhi)系統等。

直行程電(dian)(dian)動(dong)(dong)執(zhi)(zhi)行機構可以與DDZ－Ⅲ型儀(yi)表配套使用(yong)，也可以與組(zu)裝儀(yi)表及(ji)TA儀(yi)表配用(yong)。它以220V電(dian)(dian)源為(wei)動(dong)(dong)力，接受統(tong)(tong)一的標準信號4-20mA將此轉變成與輸入信號相(xiang)對應的出(chu)軸直線位移，自(zi)動(dong)(dong)地操縱(zong)調(diao)節閥或其它終端(duan)機構等(deng)完成自(zi)動(dong)(dong)調(diao)節任(ren)務，或者配用(yong)電(dian)(dian)動(dong)(dong)操作(zuo)器實(shi)行手(shou)動(dong)(dong)搖控(kong)。廣泛地用(yong)于發電(dian)(dian)廠(chang)、鋼鐵、石油、化工(gong)、輕工(gong)等(deng)工(gong)業部門的調(diao)節系統(tong)(tong)中。上海一環閥門制造有限公司(si)生產的直行程電(dian)(dian)動(dong)(dong)執(zhi)(zhi)行機構具有連續調(diao)節、手(shou)動(dong)(dong)遙控(kong)，就(jiu)地手(shou)操三種控(kong)制方式。使用(yong)DKZ型直行程電(dian)(dian)動(dong)(dong)執(zhi)(zhi)行機構的自(zi)動(dong)(dong)調(diao)節系統(tong)(tong)需配用(yong)ZPE－3101型伺服放大(da)器、DFD-1000型電(dian)(dian)動(dong)(dong)操作(zuo)器后(hou)才可以實(shi)現(xian)自(zi)動(dong)(dong)調(diao)節系統(tong)(tong)手(shou)動(dong)(dong)自(zi)動(dong)(dong)無擾動(dong)(dong)切換。

直行程電動執行器設備

功能強勁：智能型(xing)、比例式、開關式、各類(lei)(lei)信號輸出型(xing)應有。體(ti)積小(xiao)巧：體(ti)積僅相(xiang)當(dang)于(yu)同類(lei)(lei)產(chan)(chan)品的35％左右。輕便宜(yi)人(ren)：重量僅相(xiang)當(dang)于(yu)同類(lei)(lei)產(chan)(chan)品的30％左右。 　美觀大方：鋁合(he)金(jin)壓鑄外(wai)殼、精細流(liu)暢(chang)、且可減少電(dian)磁干擾。精密耐磨：蝸輪輸出軸(zhou)一體(ti)化特殊鋁合(he)金(jin)鍛造(zao)、強度(du)高(gao)、耐磨性好。

控制方式

直行程電(dian)動執行機構具有(you)連續調節、手動遙控(kong)，就地手操三種控(kong)制方式(shi)。

使用(yong)直(zhi)行程電(dian)動(dong)(dong)執行機構的自(zi)動(dong)(dong)調節(jie)系統(tong)，配用(yong)DFD－1000型電(dian)動(dong)(dong)操作器(qi)，可實現(xian)調節(jie)系統(tong)手動(dong)(dong)到(dao)自(zi)動(dong)(dong)（自(zi)動(dong)(dong)到(dao)手動(dong)(dong)）無擾動(dong)(dong)切換。

其特點為：

位置發(fa)送器具有(you)恒流(liu)輸出特性，輸出電流(liu)為d.c.4～20mA

能承受較頻繁起停

電動(dong)執行機(ji)構(gou)系(xi)統穩定性較(jiao)好
