石墨盤根填料環由石墨盤根或各種增強石墨盤根如，玻纖增強石墨盤根，不銹鋼絲增強石墨盤根，鎳絲增強石墨盤根INCONEL絲增強盤根由模具模壓成環，可用于填料函中上下端面的封口也可單獨成套使用，集合了盤根和普通石墨環的優點，特別適合于高溫高壓部位的密封。

　　石墨(mo)盤根填料環的安裝：

　　1.一次安(an)裝一枚石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)，確信每(mei)根(gen)(gen)石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)沒有粘上塵土(tu)或其它碎片。如果需要應在石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)、軸(zhou)或閥桿上涂上清潔潤(run)滑油加以潤(run)滑。多個(ge)石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)使(shi)用(yong)時要交錯安(an)裝，每(mei)枚石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)的切口錯開90度(du)。安(an)裝環(huan)(huan)(huan)時應于軸(zhou)向慢慢拉開，徑(jing)向的距離(li)以能使(shi)石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)裝到軸(zhou)上即(ji)可，使(shi)用(yong)填(tian)(tian)充工具(ju)緊固(gu)每(mei)根(gen)(gen)石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)。當足夠石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)安(an)裝完成后(hou)，用(yong)隨動(dong)件(jian)將其封(feng)閉，使(shi)用(yong)隨動(dong)件(jian)可以增加緊密程度(du)。隨動(dong)件(jian)只(zhi)是做為一種補(bu)充，保證全部石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)適當的位置，避免(mian)石(shi)(shi)墨(mo)(mo)盤(pan)(pan)(pan)根(gen)(gen)密封(feng)填(tian)(tian)料(liao)(liao)環(huan)(huan)(huan)移動(dong)。

　　2.往復(fu)泵中，填(tian)料箱(xiang)內的兩端和(he)中間還應放(fang)入(ru)導向環，以保(bao)持其(qi)同心運動和(he)受柱(zhu)塞的重力。

　　3.安(an)裝石墨(mo)盤根(gen)填料環后，扭緊螺栓(shuan)。為了在每個(ge)螺母(mu)(mu)上施加一(yi)致的(de)壓(ya)力，建議(yi)用力矩扳(ban)手(shou)或(huo)相(xiang)關的(de)計(ji)量裝置(zhi)緊固螺母(mu)(mu)。請注(zhu)意(yi)：此(ci)時裝置(zhi)如果處于無泄漏(lou)狀態，可能引起(qi)石墨(mo)盤根(gen)密封填料環燃燒。建議(yi)開(kai)啟(qi)水泵(beng)后再慢(man)慢(man)扭緊螺栓(shuan)直至漏(lou)量達(da)到允(yun)許(xu)范(fan)圍。
