失效的南寶鎮機械密封，摩擦副端麵常會留下很細的徑向裂紋，或者是徑向裂紋兼有水泡痕，甚至龜裂。這是由於密封過熱引起的，特別是陶瓷、硬質合金密封麵容易產生這類損傷。介質潤滑性差、過載、操作溫度高、線速度高、peiduicailiaozuhebudangdeng，qizhongrenheyizhongyinsu，huozheshijizhongyinsudediejia，doukeyichanshengguodademocare，ruomocarebunengjishisanfa，jiuhuichanshengranzhengjixiemifengreliewen，congerchuxianguodumosunhegaoxielou。jiejuemifengguorewenti，chugaibianduanmianmianjiwai，jianshaozaihewai，haikecaiyongjingzhixingmifengbingjiadaoliutaoqiangzhilengquexunhuanliutidaoxiangmifengmian，huozaimifengduanmianshangkailiutidonglicaolaijiayijiejue。mocaduanmianshangyouxuduoxixiaoderebandianhegulidebiansequ，zheshuomingmifengjianzaigaoyahereyingxiangxiabianxingniuqu。duiyuduanmiandederebianxing，yibandejisuanfangfashibuyunxude，yingcaiyongyouxianyuanfajisuan，yibiangaijinmifenghuandesheji。
