真空(kong)(kong)(kong)燒(shao)結(jie)(jie)爐的(de)(de)(de)工(gong)作原理(li)及啟動(dong)時不操作的(de)(de)(de)原因分析(xi)
一、主要(yao)(yao)原理(li)及用(yong)途真空(kong)(kong)(kong)燒(shao)結(jie)(jie)爐是在抽真空(kong)(kong)(kong)后(hou)充氫氣(qi)保(bao)(bao)(bao)護狀(zhuang)(zhuang)態(tai)下(xia),利用(yong)中頻感應加(jia)熱的(de)(de)(de)原理(li),使處于(yu)線圈內的(de)(de)(de)鎢坩堝產生高(gao)溫(wen),通過熱輻(fu)(fu)射(she)傳導到工(gong)作上,適(shi)用(yong)于(yu)科研、軍工(gong)單(dan)位對(dui)難熔合金如鎢、鉬及其合金的(de)(de)(de)粉末成(cheng)(cheng)型(xing)燒(shao)結(jie)(jie)。
二、主要(yao)(yao)結(jie)(jie)構及組成(cheng)(cheng)結(jie)(jie)構形式多為立式、下(xia)出(chu)料(liao)方式。其主要(yao)(yao)組成(cheng)(cheng)為:電(dian)(dian)爐本體、真空(kong)(kong)(kong)系(xi)統(tong)(tong)、水冷系(xi)統(tong)(tong)、氣(qi)動(dong)系(xi)統(tong)(tong)、液壓(ya)(ya)系(xi)統(tong)(tong)、進出(chu)料(liao)機(ji)構、底座(zuo)、工(gong)作臺、感應加(jia)熱裝置(zhi)(zhi)(鎢加(jia)熱體及*保(bao)(bao)(bao)溫(wen)材(cai)料(liao))、進電(dian)(dian)裝置(zhi)(zhi)、中頻電(dian)(dian)源(yuan)(yuan)(yuan)及電(dian)(dian)氣(qi)控(kong)(kong)制系(xi)統(tong)(tong)等。
三、主要(yao)(yao)功能(neng)(neng)在抽真空(kong)(kong)(kong)后(hou)充入氫氣(qi)保(bao)(bao)(bao)護氣(qi)體,控(kong)(kong)制爐內壓(ya)(ya)力和(he)氣(qi)氛(fen)的(de)(de)(de)燒(shao)結(jie)(jie)狀(zhuang)(zhuang)態(tai)。可(ke)用(yong)光導纖維紅(hong)外輻(fu)(fu)射(she)溫(wen)度計和(he)鎧裝熱電(dian)(dian)偶連續測溫(wen)(0~2500℃),并通過智能(neng)(neng)控(kong)(kong)溫(wen)儀與設定程序相比較后(hou),選擇執行狀(zhuang)(zhuang)態(tai)反饋給中頻電(dian)(dian)源(yuan)(yuan)(yuan),自動(dong)控(kong)(kong)制溫(wen)度的(de)(de)(de)高(gao)低及保(bao)(bao)(bao)溫(wen)程序。
真空(kong)(kong)(kong)燒(shao)結(jie)(jie)爐啟動(dong)時不操作的(de)(de)(de)原因有哪些
1、可(ke)能(neng)(neng)是總電(dian)(dian)源(yuan)(yuan)(yuan)沒接(jie)好,要(yao)(yao)檢查設備的(de)(de)(de)外接(jie)電(dian)(dian)源(yuan)(yuan)(yuan)接(jie)通情況.
2、檢查控(kong)(kong)制電(dian)(dian)源(yuan)(yuan)(yuan),使用(yong)鑰匙打開(kai)電(dian)(dian)源(yuan)(yuan)(yuan)或是合上配電(dian)(dian)柜中的(de)(de)(de)開(kai)關(guan)電(dian)(dian)源(yuan)(yuan)(yuan).
3、試(shi)著按下(xia)急(ji)停(ting)按鈕,按下(xia)不起(qi)就要(yao)(yao)放開(kai)急(ji)停(ting)按鈕.
4、還可(ke)能(neng)(neng)是電(dian)(dian)源(yuan)(yuan)(yuan)線或者是其他的(de)(de)(de)設備損壞,就要(yao)(yao)重新接(jie)真空(kong)(kong)(kong)燒(shao)結(jie)(jie)爐的(de)(de)(de)獨立電(dian)(dian)源(yuan)(yuan)(yuan)了.
