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。渣漿泰安泵用泰安機械密封的工作原理要求泰安機械密封內部無任何雜質，在組裝泰安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安機械密封嚴重漏(lou)泄。必要時可以制(zhi)作工(gong)裝在組裝前(qian)水壓試驗，檢查動靜環座是否存在影響密封的缺陷。

　　渣漿泰安泵用泰安機械密封由于密封面變形所引起的，而且泰安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安泵用泰安機械密封泄漏，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安機械密封的變(bian)形(xing)情況(kuang)。如(ru)果發生變(bian)形(xing)，用平晶(jing)檢(jian)查密(mi)封面(mian)的干(gan)涉帶的變(bian)化情況(kuang)，密(mi)封面(mian)變(bian)形(xing)存在于動環和靜環之間。
