金屬波紋管應具有較大的彈性、強度和剛度。可用於壓力達到7Mpa的場合，適用於高低溫作業，耐溫－240℃～+650℃，薄膜厚度不大於（<0.4mm），決定了要求波紋管材料具有很高的耐腐蝕性，並用於中性介質。
由於漁薪鎮金屬波紋管漁薪鎮機械密封很難保持接觸麵絕對平行，因此漁薪鎮機械密封本(ben)身(shen)的(de)內(nei)部(bu)運(yun)動(dong)也(ye)是(shi)正(zheng)常(chang)的(de)。這(zhe)種(zhong)運(yun)動(dong)通(tong)常(chang)是(shi)由(you)設(she)備(bei)和(he)安(an)裝(zhuang)公(gong)差(cha)，熱(re)膨(peng)脹(zhang)，管(guan)道(dao)應(ying)力(li)或(huo)主(zhu)軸(zhou)調(tiao)試(shi)不(bu)當(dang)引(yin)起(qi)的(de)。為(wei)了(le)始(shi)終(zhong)保(bao)持(chi)密(mi)封(feng)麵(mian)相(xiang)互(hu)配(pei)合(he)，彈(dan)簧(huang)在(zai)漁薪鎮機械密封hekedongzhuzhouzhijianqizhehengdingdetiaojiezuoyong。dangzaixuanzhuanbiaomianhezhuzhouzhijianshiyongdanxingtimifengjianshi，danxingtijiangzaizhuzhoushanglaihuiyidong。zhezhongfanfudemocajiangmosunzhuzhoushangdefangfucailiao，shiquzhuzhoushangyanghuamodebaohutuceng，bingzuizhongzaizhuzhoudemocabiaomianshangxingchengmosuncao，congerdaozhiyeticongzhuzhouxielou。bingzengjialebiyaodeweihugongzuoliang。shenzhigenghuanzhuzhou。weilejiejuezhegewenti，tongchangjiangkegenghuandetaotonganzhuangzaitianliaohanzhong。raner，jiejuefushihemosunwentidejiejuefanganshiquchuqizhongdedongtaimifeng。rujin，daduoshuzhuyaodemifengjianzhizaoshangdoushengchanfeifushixingdemosunmifengjian，yifangzhibenglingjianshangdefushixingmosun。pinghenghebupinghengde漁薪鎮機械密封的de平ping衡heng對dui接jie觸chu麵mian的de密mi封feng壓ya力li有you重zhong要yao影ying響xiang。該gai密mi封feng壓ya力li取qu決jue於yu密mi封feng本ben身shen的de有you效xiao橫heng截jie麵mian以yi及ji填tian料liao函han內nei部bu的de壓ya力li。不bu平ping衡heng密mi封feng件jian旋xuan轉zhuan表biao麵mian另ling一yi側ce的de橫heng截jie麵mian完wan全quan暴bao露lu在zai填tian料liao函han的de壓ya力li範fan圍wei內nei。這zhe種zhong情qing況kuang會hui在zai密mi封feng麵mian之zhi間jian產chan生sheng更geng高gao的de密mi封feng壓ya力li，從cong而er增zeng加jia工gong作zuo溫wen度du並bing加jia快kuai磨mo損sun速su度du。在zai高gao溫wen工gong作zuo條tiao件jian下xia或huo當dang液ye體ti具ju有you強qiang腐fu蝕shi性xing和he腐fu蝕shi性xing時shi，漁薪鎮機械密封的使用壽命將大大縮短。平衡的漁薪鎮機械密封可降低密封壓力並延長密封壽命。
