紅山街道機械密封使用時過熱會造成哪些影響？

　　紅山街道機械密封按工作條件和介質性質的不同，有耐高溫

、耐低溫紅山街道機械密封，耐高壓、耐腐蝕紅山街道機械密封，耐顆粒介質紅山街道機械密封和適應易汽化的輕質烴介質的紅山街道機械密封等，應根據不同的用處選取不同結構型式和材料的紅山街道機械密封。

，或利用特種耐腐蝕紅山街道機械密封壓蓋從外部注液冷卻，或直接冷卻腔內的密封
，等等，對降低密封端麵的溫度是十分有效。
　　失效的紅山街道機械密封，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
