樂平研磨和冷卻對密封麵都非常重要

　　在研磨過程中，閥門製造的密封麵是一個常用的整理方法，可以使樂平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。

　　樂平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，隨著對樂平機械密封yanjiudefuzamian

　　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樂平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。
