麗水介紹渣漿泵用機械密封的工作原理

  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。渣漿泵用麗水機械密封的工作原理要求麗水機械密封內部無任何雜質,在組裝麗水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麗水機械密封嚴重漏泄。必(bi)要時可以制作工(gong)裝(zhuang)(zhuang)在組裝(zhuang)(zhuang)前(qian)水壓試(shi)驗,檢查動靜環座(zuo)是(shi)否存在影(ying)響(xiang)密封的缺陷。

  渣漿麗水泵用麗水機械密封由于密封面變形所引起的,而且麗水機械密封面泄漏的概率是很高的。如果泵在啟動時就發生麗水泵用麗水機械密封泄漏,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麗水機械密封的(de)變形(xing)(xing)情況。如果發生變形(xing)(xing),用平晶檢查密封面的(de)干涉(she)帶的(de)變化(hua)情況,密封面變形(xing)(xing)存在(zai)于動環和靜(jing)環之間。

  壓缸體(ti)(ti)動(dong)(dong)態密(mi)(mi)(mi)(mi)封(feng)(feng)系(xi)統采用(yong)(yong)(yong)的(de)(de)(de)(de)是主密(mi)(mi)(mi)(mi)封(feng)(feng)設計(ji),一般(ban)都用(yong)(yong)(yong)U型(xing)密(mi)(mi)(mi)(mi)封(feng)(feng)圈。液壓缸體(ti)(ti)的(de)(de)(de)(de)往復(fu)(fu)式動(dong)(dong)態密(mi)(mi)(mi)(mi)封(feng)(feng)系(xi)統的(de)(de)(de)(de)設計(ji),開始使用(yong)(yong)(yong)了更加復(fu)(fu)雜的(de)(de)(de)(de)U型(xing)圈和同(tong)軸(zhou)(zhou)(zhou)密(mi)(mi)(mi)(mi)封(feng)(feng)組件(jian)的(de)(de)(de)(de)復(fu)(fu)合(he)式設計(ji)。密(mi)(mi)(mi)(mi)封(feng)(feng)的(de)(de)(de)(de)靜(jing)環(huan)(huan)(huan)(huan)通常固定(ding)在殼(ke)體(ti)(ti)上,動(dong)(dong)環(huan)(huan)(huan)(huan)通過彈(dan)簧(huang)、彈(dan)簧(huang)座與(yu)軸(zhou)(zhou)(zhou)一同(tong)旋(xuan)轉。靜(jing)環(huan)(huan)(huan)(huan)與(yu)殼(ke)體(ti)(ti)、動(dong)(dong)環(huan)(huan)(huan)(huan)與(yu)軸(zhou)(zhou)(zhou)形成的(de)(de)(de)(de)間隙用(yong)(yong)(yong)成型(xing)填料密(mi)(mi)(mi)(mi)封(feng)(feng)。在動(dong)(dong)環(huan)(huan)(huan)(huan)和靜(jing)環(huan)(huan)(huan)(huan)接觸的(de)(de)(de)(de)端面(mian)(mian)形成相對(dui)滑動(dong)(dong)面(mian)(mian),即動(dong)(dong)密(mi)(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)。為保證密(mi)(mi)(mi)(mi)封(feng)(feng)良好,動(dong)(dong)密(mi)(mi)(mi)(mi)封(feng)(feng)面(mian)(mian)應(ying)十分平(ping)直和光潔。彈(dan)簧(huang)力和被(bei)密(mi)(mi)(mi)(mi)封(feng)(feng)的(de)(de)(de)(de)流體(ti)(ti)壓力使動(dong)(dong)環(huan)(huan)(huan)(huan)貼緊(jin)靜(jing)環(huan)(huan)(huan)(huan)。因動(dong)(dong)環(huan)(huan)(huan)(huan)與(yu)軸(zhou)(zhou)(zhou)通過彈(dan)簧(huang)連(lian)接,動(dong)(dong)環(huan)(huan)(huan)(huan)和靜(jing)環(huan)(huan)(huan)(huan)間貼合(he)性(xing)受軸(zhou)(zhou)(zhou)的(de)(de)(de)(de)振動(dong)(dong)和擺動(dong)(dong)影(ying)響較小。靜(jing)環(huan)(huan)(huan)(huan)一般(ban)常用(yong)(yong)(yong)潤滑性(xing)好的(de)(de)(de)(de)軟質材料如石墨、填充聚四氟乙烯等,動(dong)(dong)環(huan)(huan)(huan)(huan)多用(yong)(yong)(yong)硬質合(he)金、陶(tao)瓷(ci)等材料制造。
