石墨(mo)刮(gua)片(pian)(pian)(pian)是真空(kong)泵(beng)的配件。石墨(mo)刮(gua)片(pian)(pian)(pian)之(zhi)所以(yi)應用(yong)(yong)(yong)廣泛，是因(yin)為(wei)有很多優(you)良的特(te)性：耐(nai)高溫、具有耐(nai)暫(zan)性戰耐(nai)腐化性，耐(nai)酸、堿(jian)、鹽及小氣環境的腐化，無(wu)需用(yong)(yong)(yong)油(you)和水。適用(yong)(yong)(yong)于高速運轉的真空(kong)泵(beng)，適用(yong)(yong)(yong)干式(shi)(shi)無(wu)油(you)式(shi)(shi)真空(kong)泵(beng)。泵(beng)在(zai)正(zheng)常(chang)使用(yong)(yong)(yong)下，石墨(mo)刮(gua)片(pian)(pian)(pian)的使用(yong)(yong)(yong)壽命長，碳精(jing)(jing)石墨(mo)刮(gua)片(pian)(pian)(pian)為(wei)無(wu)油(you)旋(xuan)片(pian)(pian)(pian)式(shi)(shi)真空(kong)泵(beng)旋(xuan)片(pian)(pian)(pian)，當(dang)真空(kong)泵(beng)腔(qiang)壁不(bu)平滑(hua)，碳精(jing)(jing)片(pian)(pian)(pian)易(yi)磨損掉。碳精(jing)(jing)片(pian)(pian)(pian)在(zai)使用(yong)(yong)(yong)時遇到油(you)氣或水氣環境下，易(yi)使碳精(jing)(jing)片(pian)(pian)(pian)損壞或斷裂，導致真空(kong)泵(beng)卡死。

干(gan)式(shi)真空(kong)泵(beng)保(bao)養方法：

1.安裝更換(huan)碳片之(zhi)前清理干凈氣(qi)泵缸(gang)壁,不能有任何殘渣(zha).

2.檢查缸壁(bi)是否被磨(mo)損(sun),(注:碰到(dao)不好的碳片,硬度酞(tai)高容(rong)易磨(mo)損(sun)缸壁(bi)).

3.安裝(zhuang)碳片時,注(zhu)意倒角方(fang)向千(qian)萬別裝(zhuang)反了,那(nei)樣很快就會(hui)打碎碳片.

4.定期保養(yang)氣泵軸承,加注高溫(wen)潤滑油,如軸承損壞會導致意想不到的故(gu)障(zhang),后(hou)果嚴重.

5.進氣口濾芯要保(bao)(bao)持良好工作性能,定期更換,保(bao)(bao)養.

6.碳(tan)片規(gui)格(ge)(ge)尺寸(cun), 要(yao)(yao)量好,因(yin)為磨損(sun)后很(hen)難有準確規(gui)格(ge)(ge),請從轉子的(de)槽到缸壁來量,留有少量空(kong)隙.( 要(yao)(yao)考慮到碳(tan)片的(de)膨脹系數(shu),如果一旦碳(tan)片膨脹會從兩頭擠碎(sui)碳(tan)片)

7.石墨片(pian)主要(yao)看它的材質（太硬(ying)磨損缸壁，太軟葉片(pian)消耗很快(kuai)）；精度，誤差<0.01mm（肉眼看不見的誤差可能造成真空不良，噪聲或者發熱(re)后(hou)旋(xuan)片(pian)膨脹卡死）巨大

真(zhen)空(kong)泵石墨碳片(pian)目前適用于各行業(ye)，規(gui)格已上(shang)千多種，無法(fa)明細列出，只要有碳片(pian)尺寸，我司都可(ke)以定做。
