一、TBF-10 回轉型閥門(men)電動(dong)控制裝置產品介紹

        隨著工業控(kong)(kong)制技術的(de)進步和發展，對電(dian)(dian)動(dong)閥(fa)(fa)門的(de)應(ying)用(yong)與普及提出了(le)更高的(de)要(yao)求，對電(dian)(dian)動(dong)閥(fa)(fa)門的(de)整體(ti)性(xing)能要(yao)求更高，尤其是在(zai)電(dian)(dian)動(dong)自動(dong)調(diao)節型的(de)閥(fa)(fa)門控(kong)(kong)制中(zhong)提出控(kong)(kong)制精度高、工作(zuo)可(ke)靠(kao)、性(xing)能穩定的(de)電(dian)(dian)動(dong)執行器(qi)和相應(ying)的(de)伺服電(dian)(dian)路。基于上述要(yao)求研制出SDC-4546K型數字(zi)(zi)伺服電(dian)(dian)路.此種數字(zi)(zi)伺服電(dian)(dian)路具有精度高、性(xing)能穩定、工作(zuo)可(ke)靠(kao)，對各種執行器(qi)適應(ying)性(xing)強。在(zai)電(dian)(dian)動(dong)閥(fa)(fa)門自動(dong)化的(de)控(kong)(kong)制中(zhong)得到廣泛(fan)應(ying)用(yong)。

SDC-4546K型數字伺服電路具(ju)有體(ti)積(ji)小(xiao)巧，功能齊全，安裝使用方便(bian)，調(diao)整簡單。

三、TBF-10 工作原理

        1、當SDC-4546K數(shu)字(zi)(zi)伺(si)服電(dian)(dian)(dian)(dian)(dian)路(lu)接入(ru)執行(xing)器電(dian)(dian)(dian)(dian)(dian)路(lu)中控(kong)制執行(xing)器來驅(qu)動(dong)(dong)調節閥(fa)門(men)工作。將4-20mA在(zai)輸 入(ru)信(xin)號(hao)(hao)(hao)送(song)(song)入(ru)數(shu)字(zi)(zi)處(chu)(chu)理(li)電(dian)(dian)(dian)(dian)(dian)路(lu)中將模擬信(xin)號(hao)(hao)(hao)變換成數(shu)字(zi)(zi)信(xin)號(hao)(hao)(hao)時(shi)，將數(shu)字(zi)(zi)信(xin)號(hao)(hao)(hao)送(song)(song)入(ru)數(shu)字(zi)(zi)處(chu)(chu)理(li)電(dian)(dian)(dian)(dian)(dian)路(lu)。和 閥(fa)門(men)位置信(xin)號(hao)(hao)(hao)共同(tong)送(song)(song)入(ru)數(shu)字(zi)(zi)處(chu)(chu)理(li)電(dian)(dian)(dian)(dian)(dian)路(lu)進行(xing)處(chu)(chu)理(li)，將其處(chu)(chu)理(li)好的數(shu)字(zi)(zi)信(xin)號(hao)(hao)(hao)再(zai)送(song)(song)入(ru)邏輯鑒別電(dian)(dian)(dian)(dian)(dian)路(lu)。 輸入(ru)信(xin)號(hao)(hao)(hao)檢測電(dian)(dian)(dian)(dian)(dian)路(lu)的輸出(chu)，送(song)(song)到(dao)邏輯鑒別電(dian)(dian)(dian)(dian)(dian)路(lu)，鑒別出(chu)開閥(fa)或(huo)(huo)關(guan)閥(fa)電(dian)(dian)(dian)(dian)(dian)路(lu)所需要的信(xin)號(hao)(hao)(hao)，此開 閥(fa)、關(guan)閥(fa)信(xin)號(hao)(hao)(hao)再(zai)經過抗(kang)振電(dian)(dian)(dian)(dian)(dian)路(lu)進行(xing)除(chu)振處(chu)(chu)理(li)，再(zai)去推動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)機(ji)的驅(qu)動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)路(lu)驅(qu)動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)機(ji)開閥(fa)或(huo)(huo)關(guan)閥(fa)， 同(tong)在(zai)開閥(fa)或(huo)(huo)關(guan)閥(fa)時(shi)閥(fa)門(men)位置信(xin)號(hao)(hao)(hao)輸出(chu)4-20mA的閥(fa)門(men)位置信(xin)號(hao)(hao)(hao)。

        2、單相220V執行(xing)器所用調節(jie)型電氣(qi)控(kong)制(zhi)。

        3、當(dang)SDC-4546K型數(shu)字(zi)伺(si)服板接入(ru)執行器(qi)的整體(ti)將其(qi)按原理圖將各種功能(neng)導線接好(hao)。在(zai)輸(shu)(shu)(shu)入(ru)端接 入(ru)直流電(dian)流控制信號(hao)(hao)4-20mA。在(zai)輸(shu)(shu)(shu)出(chu)端接入(ru)電(dian)流表，觀測其(qi)輸(shu)(shu)(shu)出(chu)電(dian)流。當(dang)輸(shu)(shu)(shu)入(ru)信號(hao)(hao)大于反饋(kui)信 號(hao)(hao)時經(jing)SDC數(shu)字(zi)伺(si)服電(dian)路處理，輸(shu)(shu)(shu)出(chu)開閥(fa)信號(hao)(hao)閥(fa)門向開閥(fa)方向運轉(zhuan)。運轉(zhuan)到(dao)輸(shu)(shu)(shu)出(chu)信號(hao)(hao)等于輸(shu)(shu)(shu)入(ru) 信號(hao)(hao)時停。

        4、當輸(shu)入(ru)信(xin)號(hao)小于(yu)反(fan)饋信(xin)號(hao)時經SDC數字伺服電路(lu)處理輸(shu)出關閥信(xin)號(hao)閥門向(xiang)關閥方向(xiang)運轉，運轉到(dao) 輸(shu)出信(xin)號(hao)等于(yu)輸(shu)入(ru)信(xin)號(hao)時停止。

        5、當(dang)輸入信(xin)號等于輸出信(xin)號時(shi)經SDC數字伺(si)服處理無(wu)信(xin)號輸出，此時(shi)輸出閥(fa)位信(xin)號（4-20mA)等于 輸入的電流值(zhi)。當(dang)伺(si)服電路正常工作(zuo)時(shi)調節閥(fa)運行平穩應無(wu)振(zhen)蕩現象。

        6、當(dang)執(zhi)行器有振蕩(dang)現象時請將SDC數字伺服板(ban)上的(de)抗振開關3撥向接通位置即可。
