  3.檢查真(zhen)(zhen)空(kong)(kong)燒結爐的(de)(de)真(zhen)(zhen)空(kong)(kong)泵電源系統(tong),皮(pi)帶盤皮(pi)帶松緊,真(zhen)(zhen)空(kong)(kong)泵油(you)是否位于(yu)油(you)封觀察孔中線。檢查妥后,人工(gong)轉動真(zhen)(zhen)空(kong)(kong)泵皮(pi)帶盤,如無異常,可(ke)在(zai)關(guan)閉蝶(die)閥(fa)的(de)(de)情況(kuang)下,啟動真(zhen)(zhen)空(kong)(kong)泵。

  4.檢(jian)查(cha)真(zhen)(zhen)空爐體內(nei)情況,要求真(zhen)(zhen)空爐體內(nei)上等衛(wei)生,感應圈(quan)絕緣良好,密封真(zhen)(zhen)空膠帶具有彈性,尺(chi)寸合格。

  5.檢查真空燒結(jie)爐的杠桿手把啟動(dong)是否靈活。

  6.檢(jian)查轉動式(shi)麥(mai)氏真空(kong)計是否合乎要求(qiu)。

  7.檢查(cha)石墨坩堝,裝爐配件是否齊(qi)全。

  在(zai)以上準備就緒后,接通電(dian)源,中(zhong)頻(pin)電(dian)源合閘,按中(zhong)頻(pin)啟動(dong)規則,試啟動(dong)變(bian)頻(pin),成功后停止變(bian)頻(pin),方可開真空燒結爐。
