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。渣漿泵用泰來機械密封的工作原理要求泰來機械密封內部無任何雜質，在組裝泰來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泰來機械密封嚴重漏泄。必(bi)要時可以制(zhi)作工裝(zhuang)(zhuang)在(zai)組裝(zhuang)(zhuang)前水壓試(shi)驗(yan)，檢(jian)查動(dong)靜(jing)環座是(shi)否(fou)存(cun)在(zai)影響密(mi)封(feng)的缺(que)陷。

　　渣漿泰來泵用泰來機械密封由于密封面變形所引起的，而且泰來機械密封面泄漏的概率是很高的。如果泵在啟動時就發生泰來泵用泰來機械密封泄漏，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泰來機械密封的變(bian)形情(qing)(qing)況。如果發生變(bian)形，用(yong)平晶檢查密(mi)封(feng)面的干涉帶的變(bian)化(hua)情(qing)(qing)況，密(mi)封(feng)面變(bian)形存在于動環和靜(jing)環之(zhi)間。
