真(zhen)(zhen)(zhen)空(kong)(kong)(kong)燒結(jie)(jie)爐(lu)的(de)(de)(de)工作(zuo)原(yuan)理及(ji)(ji)啟(qi)(qi)動(dong)時(shi)不操作(zuo)的(de)(de)(de)原(yuan)因(yin)(yin)分析
一、主(zhu)(zhu)要(yao)(yao)原(yuan)理及(ji)(ji)用(yong)途真(zhen)(zhen)(zhen)空(kong)(kong)(kong)燒結(jie)(jie)爐(lu)是在抽真(zhen)(zhen)(zhen)空(kong)(kong)(kong)后充(chong)氫氣(qi)(qi)保(bao)護(hu)狀(zhuang)態(tai)下,利用(yong)中(zhong)(zhong)頻(pin)(pin)感應加熱(re)的(de)(de)(de)原(yuan)理,使處于(yu)線圈(quan)內的(de)(de)(de)鎢坩堝產生高溫(wen),通(tong)過熱(re)輻射(she)(she)傳導到工作(zuo)上(shang),適(shi)用(yong)于(yu)科研、軍工單位對難熔合(he)金(jin)如鎢、鉬及(ji)(ji)其合(he)金(jin)的(de)(de)(de)粉末(mo)成(cheng)(cheng)型燒結(jie)(jie)。
二、主(zhu)(zhu)要(yao)(yao)結(jie)(jie)構及(ji)(ji)組(zu)成(cheng)(cheng)結(jie)(jie)構形(xing)式多為立式、下出(chu)料(liao)方式。其主(zhu)(zhu)要(yao)(yao)組(zu)成(cheng)(cheng)為:電(dian)(dian)(dian)(dian)爐(lu)本體、真(zhen)(zhen)(zhen)空(kong)(kong)(kong)系(xi)統、水冷系(xi)統、氣(qi)(qi)動(dong)系(xi)統、液壓系(xi)統、進(jin)出(chu)料(liao)機構、底座、工作(zuo)臺、感應加熱(re)裝(zhuang)置(鎢加熱(re)體及(ji)(ji)*保(bao)溫(wen)材料(liao))、進(jin)電(dian)(dian)(dian)(dian)裝(zhuang)置、中(zhong)(zhong)頻(pin)(pin)電(dian)(dian)(dian)(dian)源(yuan)及(ji)(ji)電(dian)(dian)(dian)(dian)氣(qi)(qi)控(kong)制(zhi)(zhi)系(xi)統等。
三、主(zhu)(zhu)要(yao)(yao)功能(neng)(neng)在抽真(zhen)(zhen)(zhen)空(kong)(kong)(kong)后充(chong)入氫氣(qi)(qi)保(bao)護(hu)氣(qi)(qi)體,控(kong)制(zhi)(zhi)爐(lu)內壓力和(he)(he)氣(qi)(qi)氛的(de)(de)(de)燒結(jie)(jie)狀(zhuang)態(tai)。可(ke)用(yong)光導纖維紅外(wai)輻射(she)(she)溫(wen)度(du)計和(he)(he)鎧(kai)裝(zhuang)熱(re)電(dian)(dian)(dian)(dian)偶連(lian)續測(ce)溫(wen)(0~2500℃),并通(tong)過智(zhi)能(neng)(neng)控(kong)溫(wen)儀與(yu)設(she)定程(cheng)序相比較后,選擇(ze)執(zhi)行(xing)狀(zhuang)態(tai)反饋給中(zhong)(zhong)頻(pin)(pin)電(dian)(dian)(dian)(dian)源(yuan),自動(dong)控(kong)制(zhi)(zhi)溫(wen)度(du)的(de)(de)(de)高低(di)及(ji)(ji)保(bao)溫(wen)程(cheng)序。
真(zhen)(zhen)(zhen)空(kong)(kong)(kong)燒結(jie)(jie)爐(lu)啟(qi)(qi)動(dong)時(shi)不操作(zuo)的(de)(de)(de)原(yuan)因(yin)(yin)有哪些(xie)
1、可(ke)能(neng)(neng)是總電(dian)(dian)(dian)(dian)源(yuan)沒接好,要(yao)(yao)檢查設(she)備(bei)的(de)(de)(de)外(wai)接電(dian)(dian)(dian)(dian)源(yuan)接通(tong)情(qing)況.
2、檢查控(kong)制(zhi)(zhi)電(dian)(dian)(dian)(dian)源(yuan),使用(yong)鑰(yao)匙打開(kai)電(dian)(dian)(dian)(dian)源(yuan)或是合(he)上(shang)配(pei)電(dian)(dian)(dian)(dian)柜中(zhong)(zhong)的(de)(de)(de)開(kai)關電(dian)(dian)(dian)(dian)源(yuan).
3、試著按(an)下急(ji)停(ting)按(an)鈕,按(an)下不起就要(yao)(yao)放開(kai)急(ji)停(ting)按(an)鈕.
4、還可(ke)能(neng)(neng)是電(dian)(dian)(dian)(dian)源(yuan)線或者是其他的(de)(de)(de)設(she)備(bei)損壞,就要(yao)(yao)重新接真(zhen)(zhen)(zhen)空(kong)(kong)(kong)燒結(jie)(jie)爐(lu)的(de)(de)(de)獨立電(dian)(dian)(dian)(dian)源(yuan)了.
