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，北辰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、雙端麵和幾級串聯北辰機械密封。由一對密封端麵組成的為單端麵北辰機械密封，由兩對密封端麵麵對麵或背對背組成的為雙端麵北辰機械密封，由兩對或以上密封端麵組成的串聯安裝的為串聯北辰機械密封。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。前者與單端麵北辰機械密封相同，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，但是各種價格的北辰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，一些較為廉價的北辰機械密封效(xiao)果(guo)稍(shao)差(cha)，安(an)裝(zhuang)的(de)過(guo)程(cheng)中(zhong)也(ye)要(yao)注(zhu)意(yi)很(hen)多(duo)問(wen)題(ti)，這(zhe)一(yi)點(dian)是(shi)希(xi)望(wang)采(cai)購(gou)人(ren)員(yuan)能(neng)夠(gou)明(ming)白(bai)的(de)，根(gen)據(ju)設(she)備(bei)類(lei)型(xing)的(de)不(bu)同(tong)，在(zai)購(gou)買(mai)機(ji)械(xie)密(mi)封(feng)的(de)時(shi)候(hou)要(yao)做(zuo)到(dao)精(jing)挑(tiao)細(xi)選(xuan)。
