石墨(mo)刮片(pian)(pian)(pian)(pian)(pian)是真(zhen)(zhen)空泵(beng)(beng)(beng)的配件(jian)。石墨(mo)刮片(pian)(pian)(pian)(pian)(pian)之所以应用(yong)广泛，是因为(wei)有很(hen)多优良(liang)的特性(xing)(xing)：耐(nai)高(gao)温、具有耐(nai)暂性(xing)(xing)战耐(nai)腐(fu)化性(xing)(xing)，耐(nai)酸(suan)、碱(jian)、盐及小气环境的腐(fu)化，无(wu)需(xu)用(yong)油和(he)水(shui)。适(shi)用(yong)于高(gao)速运转的真(zhen)(zhen)空泵(beng)(beng)(beng)，适(shi)用(yong)干式无(wu)油式真(zhen)(zhen)空泵(beng)(beng)(beng)。泵(beng)(beng)(beng)在正常使(shi)(shi)用(yong)下，石墨(mo)刮片(pian)(pian)(pian)(pian)(pian)的使(shi)(shi)用(yong)寿(shou)命长，碳精(jing)(jing)石墨(mo)刮片(pian)(pian)(pian)(pian)(pian)为(wei)无(wu)油旋片(pian)(pian)(pian)(pian)(pian)式真(zhen)(zhen)空泵(beng)(beng)(beng)旋片(pian)(pian)(pian)(pian)(pian)，当(dang)真(zhen)(zhen)空泵(beng)(beng)(beng)腔壁不(bu)平滑(hua)，碳精(jing)(jing)片(pian)(pian)(pian)(pian)(pian)易(yi)磨损掉。碳精(jing)(jing)片(pian)(pian)(pian)(pian)(pian)在使(shi)(shi)用(yong)时遇到油气或(huo)水(shui)气环境下，易(yi)使(shi)(shi)碳精(jing)(jing)片(pian)(pian)(pian)(pian)(pian)损坏或(huo)断裂，导致(zhi)真(zhen)(zhen)空泵(beng)(beng)(beng)卡死(si)。

干(gan)式真空泵保养方(fang)法：

1.安装更换(huan)碳片(pian)之前(qian)清理干净气泵缸壁,不能有任(ren)何(he)残渣.

2.检(jian)查(cha)缸壁是否被磨损,(注:碰(peng)到不好的碳(tan)片(pian),硬(ying)度酞高容易磨损缸壁).

3.安装(zhuang)碳片时(shi),注(zhu)意倒角方向千万别装(zhuang)反了,那样很(hen)快就会打碎碳片.

4.定(ding)期保养(yang)气泵轴(zhou)承,加注高温(wen)润滑(hua)油,如轴(zhou)承损坏会导致意想(xiang)不(bu)到的故(gu)障,后(hou)果严重.

5.进气口滤芯要保持良好工(gong)作性能,定(ding)期更换,保养.

6.碳片(pian)规格(ge)尺(chi)寸, 要量(liang)好,因为磨(mo)损(sun)后很难(nan)有(you)准确规格(ge),请从转(zhuan)子(zi)的槽到缸壁来量(liang),留(liu)有(you)少(shao)量(liang)空隙.( 要考虑到碳片(pian)的膨(peng)胀系数,如果一旦(dan)碳片(pian)膨(peng)胀会从两头挤碎碳片(pian))

7.石墨片(pian)主要(yao)看它的材质（太(tai)硬磨损(sun)缸壁，太(tai)软叶片(pian)消耗很(hen)快(kuai)）；精度，误差<0.01mm（肉眼看不见的误差可(ke)能造成(cheng)真空不良，噪声或者发热后旋片(pian)膨胀卡死(si)）巨大
