反壓狀態是不良的工作狀態，介質中的顆粒、雜質很容易進入密封面，使密封失效。磨軸的主要件為橡膠波紋管，且由于上端密封面處于不良潤滑狀態，動靜環之間的摩擦力矩大于橡膠波紋管與軸之間的傳遞轉矩，從而發生相對轉動。動、靜環輔助密封由于受到污水中的弱酸、弱堿的腐蝕，橡膠件已無彈性。渣漿泵用什玲鎮機械密封的工作原理要求什玲鎮機械密封內部無任何雜質，在組裝什玲鎮機械密封前要徹底清掃動環、靜環、軸套等部件，檢查動靜環表面是否存在劃痕、裂紋等缺陷，這些缺陷存在會造成什玲鎮機械密封嚴重漏(lou)泄。必要(yao)時可以制作工裝在(zai)組裝前水(shui)壓試驗，檢查動(dong)靜環座是否存在(zai)影響(xiang)密封(feng)的缺陷。

　　渣漿什玲鎮泵用什玲鎮機械密封由于密封面變形所引起的，而且什玲鎮機械密封面泄漏的概率是很高的。如果泵在啟動時就發生什玲鎮泵用什玲鎮機械密封泄漏，而拆查密封面時看不見有損壞的地方，這時就應該用平晶檢查什玲鎮機械密封的變形(xing)情況。如果發生變形(xing)，用(yong)平晶檢查密封(feng)面(mian)的干涉帶的變化情況，密封(feng)面(mian)變形(xing)存在于動(dong)環和靜環之間(jian)。
