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。渣漿池州泵用池州機械密封的工作原理要求池州機械密封內部無任何雜質，在組裝池州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池州機械密封嚴(yan)重(zhong)漏泄。必要時可以(yi)制作(zuo)工裝(zhuang)在組(zu)裝(zhuang)前(qian)水壓試驗，檢(jian)查(cha)動靜環座是否(fou)存在影響密(mi)封的缺陷。

　　渣漿池州泵用池州機械密封由于密封面變形所引起的，而且池州機械密封面泄漏的概率是很高的。如果泵在啟動時就發生池州泵用池州機械密封泄漏，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池州機械密封的(de)變形(xing)情況。如果發(fa)生變形(xing)，用(yong)平晶檢查密封面(mian)的(de)干涉帶的(de)變化情況，密封面(mian)變形(xing)存在于動環和靜環之間。
