根據不同的工作條件和介質性質，繁峙機械密封包括耐高低溫繁峙機械密封、耐高壓耐腐蝕繁峙機械密封、耐顆粒介質繁峙機械密封和適用於易汽化輕烴介質的繁峙機械密封等。應根據不同用途選擇不同結構類型和材料的繁峙機械密封。
一個或兩個端麵出現間隙，說明兩個端麵之間的距離太大，當兩個端麵緊密閉合時，就會出現間隙。端麵分離的常見原因是進口繁峙機械密封介jie質zhi快kuai速su蒸zheng發fa。例li如ru，水shui，尤you其qi是shi在zai熱re水shui係xi統tong或huo含han有you冷leng凝ning水shui的de液ye體ti中zhong，蒸zheng發fa時shi會hui膨peng脹zhang，從cong而er將jiang兩liang端duan分fen開kai。泵beng的de氣qi蝕shi和he密mi封feng的de堵du塞sai也ye可ke能neng是shi密mi封feng端duan麵mian間jian隙xi的de原yuan因yin。這zhe種zhong情qing況kuang下xia，不bu是shi振zhen動dong和he聯lian軸zhou器qi不bu對dui中zhong造zao成cheng的de，因yin為wei不bu足zu以yi使shi端duan麵mian凹ao口kou。降jiang低di端duan麵mian溫wen度du是shi防fang止zhi端duan麵mian被bei介jie質zhi快kuai速su蒸zheng發fa損sun壞huai的de常chang用yong方fang法fa。同tong時shi也ye有you利li於yu使shi用yong導dao熱re性xing好hao的de材cai料liao，如ru鎳nie基ji硬ying質zhi合he金jin、浸銅石墨等。此外，使用平衡繁峙機械密封，或使用特殊的耐腐蝕繁峙機械密封壓蓋從外部注入液體進行冷卻，或直接冷卻腔內的密封等。在降低密封端麵溫度方麵非常有效。
