  真空燒(shao)結(jie)爐使用注(zhu)意事項有哪些呢

  真空燒結爐使用注(zhu)意事(shi)項有哪些呢(ni)?今天,小編(bian)和大家介紹下。

  1.在送入(ru)真空燒結爐子之前(qian),必須在進(jin)給前(qian)清潔和干燥所有工(gong)件,以防止(zhi)水(shui)分和溢出。

  2.如果找到了每個變送器的位置,應立即(ji)停止限(xian)位關(guan)閉,控制(zhi)錯誤等現象,不要控制(zhi)消除措施,也不要損壞機(ji)器零件。

  3.真空(kong)燒結爐不應(ying)過載(zai),購(gou)買時,一般(ban)廠商給出工(gong)作(zuo)溫(wen)度(du)的(de)(de)類(lei)別(bie),***高工(gong)作(zuo)溫(wen)度(du)是允許真空(kong)中元(yuan)(yuan)(yuan)件(jian)的(de)(de)表面溫(wen)度(du)它不是指加(jia)熱(re)物(wu)質(zhi)(zhi)的(de)(de)溫(wen)度(du)或(huo)加(jia)熱(re)元(yuan)(yuan)(yuan)件(jian)周圍的(de)(de)溫(wen)度(du)。注意,真空(kong)加(jia)熱(re)元(yuan)(yuan)(yuan)件(jian)本(ben)身的(de)(de)溫(wen)度(du)比周圍的(de)(de)介質(zhi)(zhi)溫(wen)度(du)和要(yao)加(jia)熱(re)的(de)(de)溫(wen)度(du)高100°C。

  4.爐測量(liang)溫(wen)度(du)均(jun)勻性時(shi),必須注意成(cheng)束法中(zhong)測量(liang)溫(wen)度(du)觸點的位置(zhi)和加(jia)熱(re)元(yuan)件的角度(du)。為了避免加(jia)熱(re)元(yuan)件與產品之間(jian)的反(fan)應,特別是它是否與真(zhen)空(kong)加(jia)熱(re)元(yuan)件(例如銅(tong),鋁,鋅(xin),錫,鉛等(deng))接觸,是為了防止(zhi)細粉,熔體,蒸汽等(deng)。形成(cheng)表面腐蝕的“孔(kong)”,橫截面變小,隨后過熱(re)并燃(ran)燒。

  5.真空(kong)燒結爐(lu)兒童加(jia)熱(re)后,不能(neng)突然破壞真空(kong)系統,并(bing)且切勿打開(kai)熱(re)的爐(lu)灶門。注(zhu)入空(kong)氣之前,請務必(bi)(bi)關(guan)閉真空(kong)計,以(yi)防(fang)止真空(kong)計的性能(neng)下(xia)降。不要在400°C以(yi)上迅速冷(leng)(leng)卻。當溫度(du)高,真空(kong)度(du)差或(huo)冷(leng)(leng)熱(re)變化大時,真空(kong)加(jia)熱(re)元件易于氧化。可以(yi)停止鉬爐(lu)以(yi)保護氮(dan)氣,必(bi)(bi)須將其(qi)冷(leng)(leng)卻至(zhi)200°C以(yi)下(xia),并(bing)且可以(yi)打開(kai)80°C以(yi)下(xia)的門以(yi)進行常(chang)規維(wei)護。

  6.冷(leng)(leng)卻系(xi)統(tong)是(shi)爐(lu)子(zi)的(de)(de)(de)(de)重要部(bu)分。冷(leng)(leng)卻通(tong)道(dao)必須直通(tong),否(fou)則水(shui)(shui)(shui)(shui)溫將升高,并(bing)(bing)(bing)且(qie)儀(yi)器(qi)將停止(zhi)運轉。目的(de)(de)(de)(de)是(shi)使用可(ke)生物(wu)(wu)降解(jie)的(de)(de)(de)(de)化(hua)學助劑處(chu)理冷(leng)(leng)卻水(shui)(shui)(shui)(shui),以(yi)保持礦物(wu)(wu)漂浮并(bing)(bing)(bing)減(jian)少橡膠管(guan),蛇形管(guan)和水(shui)(shui)(shui)(shui)蓋中(zhong)沉積物(wu)(wu)的(de)(de)(de)(de)堆積。這通(tong)常是(shi)使用自動(dong)設備完成的(de)(de)(de)(de),該設備可(ke)監(jian)視水(shui)(shui)(shui)(shui)的(de)(de)(de)(de)電(dian)導(dao)率,自動(dong)補充化(hua)學藥品,清潔沖洗通(tong)道(dao)并(bing)(bing)(bing)添加(jia)淡(dan)水(shui)(shui)(shui)(shui)。結合隨附的(de)(de)(de)(de)蒸汽過(guo)(guo)濾系(xi)統(tong),該方法還可(ke)以(yi)控制(zhi)水(shui)(shui)(shui)(shui)的(de)(de)(de)(de)酸(suan)(suan)堿度,并(bing)(bing)(bing)防止(zhi)冷(leng)(leng)卻水(shui)(shui)(shui)(shui)系(xi)統(tong)中(zhong)沉積過(guo)(guo)多的(de)(de)(de)(de)礦物(wu)(wu)質。燒結爐(lu)系(xi)統(tong)工作穩定后(hou),應每月至少執行一次水(shui)(shui)(shui)(shui)質測試,以(yi)防止(zhi)處(chu)理和缺陷。擴散(san)泵的(de)(de)(de)(de)波紋管(guan)冷(leng)(leng)卻器(qi)需(xu)要特別注意,應始終進(jin)行檢(jian)查。如果堵(du)塞,則擴散(san)泵將過(guo)(guo)熱并(bing)(bing)(bing)失去其(qi)(qi)功能,擴散(san)泵加(jia)熱器(qi)將燃(ran)燒,從而導(dao)致昂貴且(qie)費時的(de)(de)(de)(de)維修。燒結爐(lu)安裝蛇形冷(leng)(leng)卻管(guan)后(hou),從水(shui)(shui)(shui)(shui)源上切(qie)下水(shui)(shui)(shui)(shui)通(tong)道(dao),將其(qi)(qi)排(pai)干并(bing)(bing)(bing)讓(rang)壓縮(suo)空氣(qi)通(tong)過(guo)(guo),或用稀乙(yi)酸(suan)(suan)溶液洗滌(di)。

  7.真(zhen)空(kong)燒結爐經常(至(zhi)少每天或在(zai)每節課之前(qian))發生短路(lu),爐子中的(de)(de)雜質(例(li)如(ru)氧(yang)化(hua)物)會掉(diao)落到電氣部件(jian)上,以(yi)防止電刷,掃帚和壓縮空(kong)氣,清潔桌等,甚至(zhi)烘烤鉬(mu)加熱棒。每次(ci)使用后,都必須小心地從氧(yang)化(hua)物膜上除(chu)去耐熱鋼構件(jian),例(li)如(ru)基體,鉬(mu)棒和爐溫層,且不(bu)得敲(qiao)擊(ji)。如(ru)果不(bu)及(ji)時清除(chu)諸如(ru)氧(yang)化(hua)鈦(tai)之類的(de)(de)雜質,則熔(rong)化(hua)的(de)(de)零件(jian),熱層和鉬(mu)絲將(jiang)熔(rong)化(hua)。
