在研磨過程中，閥門製造的密封麵是一個常用的整理方法，可以使盤龍機械密封摩擦端麵尺寸精度提高，閥門的密封麵，幾何粗糙度和表麵粗糙度，但不能提高密封表麵的相互位置精度。
盤龍機械密封麵研磨包括五個方麵的基本原理：研磨運動、研磨工藝、研磨速度、研磨壓力和研磨餘量。研磨過程好一起研究密封麵，隨著對盤龍機械密封yanjiudefuzamian，zhijiandebiaomianhemifengmoliaomojuyanjiuxiangduiyundongshi，mifengquanbiaomian，moliaomojuyanjiubufenhemifengmianzhijiandehuadonghuogundong，qieduanmifengquanshangbobodeyicengjinshubiaomian。mifengtufengbufendequan，biaomianyanmo，ranhouzhujiandadaosuoyaoqiudejihexingzhuang。bujinshijinshumoliaodeyanmojiagong，yijihuaxuezuoyong。yanmoyoukeshijiagongbiaomianxingchengdeyanghuamo，congerjiakuaiyanmoguocheng。dimianyundongxiangduiyundongdebiaomianhemifengquanmifengquandeyanjiu，duimeigediandebiaomianshangdedaoluhexiangduihuadongdeyanjiuyinggaishiyiyangde。hexiangduiyundongfangxianggaibian。gaibianmifenghuanneidemeigelizidebiaomianshangyundongdefangxiangbuhuizhongfutamendeguiji，yibimianmosunmingxianzengjialemifenghuandebiaomiancucaodu。ciwai，yundongfangxiangdegaibianbunengshimolifenbubijiaojunyun，qiejunyunqieduanjinshumifenghuandebiaomian。

為了不讓泵水通過軸與密封間隙泄漏，由出口冷凝泵或在鹽水中的母管引至密封水。給水泵是一種具有一定溫度、高溫的水通過泵軸或泵體金屬容器用盤龍機械密封將熱量傳給軸承，使軸承溫度升高。為了控製傳熱，所以密封的水也起到冷卻作用。
