東鄉需高度重視泵的機械密封
，不管是在選購還是安裝過程中

，由於在市場上各種東鄉機械密封的價格不一樣，當然也帶來了內在品質的不同
，所以要求購買人員要按照企業的需求確定購買哪一種密封。

　　為了適應實際應用中轉軸的尺寸、轉速以及密封壓力、溫度、介質特性等參數變化的需要，東鄉機械密封己派生出多種設計結構，按其作用原理和結構分類如下，按密封端而的對數分為單端麵
、雙端麵和幾級串聯東鄉機械密封。由一對密封端麵組成的為單端麵東鄉機械密封，由兩對密封端麵麵對麵或背對背組成的為雙端麵東鄉機械密封，由兩對或以上密封端麵組成的串聯安裝的為串聯東鄉機械密封。按密封流體所處的壓力狀態分類分為單級密封
、雙級密封和多級密封。使密封流體處於一種壓力狀態為單級密封，處於兩種壓力狀態為雙級密封。前者與單端麵東鄉機械密封相同，後者兩極密封串聯布置，密封流體壓力依次遞減，可用於高壓工況。

　　雖說都是橡膠產品，但是各種價格的東鄉機械密封在使用體驗上還是有很大差別的

，質量好的封閉效能更好

，壽命更長，也會帶來更多的成本支出
