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。渣漿泵用蘇州機械密封的工作原理要求蘇州機械密封內部無任何雜質,在組裝蘇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蘇州機械密封嚴(yan)重漏(lou)泄。必要(yao)時(shi)可以制作工裝(zhuang)在組裝(zhuang)前(qian)水壓試驗(yan),檢(jian)查動(dong)靜環座是否存在影響密封的缺陷。
渣漿蘇州泵用蘇州機械密封由于密封面變形所引起的,而且蘇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蘇州泵用蘇州機械密封泄漏,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蘇州機械密封的變形(xing)情況(kuang)。如果發生變形(xing),用平晶檢查(cha)密(mi)封(feng)面的干(gan)涉帶的變化(hua)情況(kuang),密(mi)封(feng)面變形(xing)存在于動環和靜環之間。
