　　傳動形式多，但是宜都機械密封的更換工作大同小異，首先拆前需確認電(dian)機處(chu)于檢修狀態，擰下加油螺塞，用吸管把密封座腔內的潤滑(hua)油吸出。準備好放置泵零件(jian)的工作臺及(ji)拆裝(zhuang)工具，切勿(wu)任意亂放亂用，避免碰(peng)壞泵的零部件(jian)。

　　拆對分式聯軸(zhou)器：先把聯軸(zhou)器的(de)固定內六角螺(luo)釘擰下(xia)來，再輕(qing)輕(qing)把聯軸(zhou)器的(de)一半(ban)從軸(zhou)上慢(man)(man)慢(man)(man)拉下(xia)，注意不(bu)要掉(diao)了，再用(yong)梅花扳手擰下(xia)泵軸(zhou)吊(diao)緊(jin)螺(luo)栓和擋塊，讓葉輪慢(man)(man)慢(man)(man)下(xia)沉至泵體，然后拆下(xia)另(ling)外一半(ban)聯軸(zhou)器，拿下(xia)泵軸(zhou)擋圈。

　　拆卸宜都機械密封：抓(zhua)住密(mi)封(feng)彈簧順(shun)著泵軸往(wang)上提(ti)，就能拆下(xia)來了。

　　拆卸并(bing)清(qing)洗(xi)(xi)軸(zhou)承(cheng)(cheng)座：先輕輕松動一(yi)下軸(zhou)承(cheng)(cheng)座后(hou)用(yong)拆卸螺栓頂(ding)起軸(zhou)承(cheng)(cheng)座，并(bing)且沿著泵軸(zhou)往上提而卸下，再用(yong)噴氣燃料清(qing)洗(xi)(xi)軸(zhou)承(cheng)(cheng)及座，裝前晾干并(bing)涂抹少許20號機械油用(yong)來潤滑保護。

　　拆密封(feng)(feng)座(zuo)：擰下(xia)密封(feng)(feng)座(zuo)壓(ya)緊螺母，輕(qing)輕(qing)卸下(xia)密封(feng)(feng)座(zuo)并清(qing)洗。

　　宜都機械密封裝(zhuang)配：在(zai)動、靜(jing)環(huan)鏡(jing)面上(shang)(shang)涂(tu)一層潔凈的(de)20號潤滑油，導軸承座也抹(mo)上(shang)(shang)潤滑油，先把靜(jing)環(huan)輕(qing)輕(qing)定位裝(zhuang)入導軸承座，再在(zai)泵(beng)軸上(shang)(shang)抹(mo)上(shang)(shang)潤滑油，把動環(huan)部分輕(qing)輕(qing)裝(zhuang)入泵(beng)軸上(shang)(shang)，用手(shou)輕(qing)推密封環(huan)應能伸縮(suo)自(zi)如，注意動、靜(jing)環(huan)部分的(de)防轉(zhuan)部位需裝(zhuang)配到(dao)位。

　　裝聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)：在電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)裝上(shang)(shang)擋(dang)(dang)圈(quan)，裝上(shang)(shang)一半聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)，再在泵(beng)軸(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)槽內裝上(shang)(shang)擋(dang)(dang)塊并用梅花扳手(shou)擰緊螺(luo)栓；再裝上(shang)(shang)另(ling)一半聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)擰上(shang)(shang)內六角螺(luo)釘(ding)。安裝聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)正確的檢查要(yao)求：對分式聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)上(shang)(shang)下間隙需要(yao)均(jun)勻，用手(shou)盤動聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)幾圈(quan)檢查轉動的靈活性。

　　裝(zhuang)密封座(zuo)：先將密封座(zuo)裝(zhuang)入(ru)橡膠油封，再把密封座(zuo)裝(zhuang)入(ru)泵(beng)蓋(gai)(gai)(gai)并壓在(zai)軸(zhou)承座(zuo)上(shang)，擰緊螺(luo)(luo)(luo)母，確保(bao)所有安(an)(an)裝(zhuang)螺(luo)(luo)(luo)釘緊固。當安(an)(an)裝(zhuang)螺(luo)(luo)(luo)釘被用作密封與軸(zhou)之(zhi)間的驅動時(shi)(shi)，軸(zhou)應(ying)打埋頭孔來(lai)加(jia)固連(lian)接，緊固壓蓋(gai)(gai)(gai)螺(luo)(luo)(luo)栓時(shi)(shi)應(ying)該平穩緊固，并且不(bu)要(yao)使壓蓋(gai)(gai)(gai)受彈(dan)力。在(zai)可(ke)能的地方使用4個以上(shang)螺(luo)(luo)(luo)釘的等間距壓蓋(gai)(gai)(gai)，緊固壓蓋(gai)(gai)(gai)螺(luo)(luo)(luo)栓時(shi)(shi)，用塞(sai)尺檢查(cha)軸(zhou)與壓蓋(gai)(gai)(gai)之(zhi)間的間隙，這(zhe)在(zai)密封腔對壓蓋(gai)(gai)(gai)不(bu)導(dao)向時(shi)(shi)，顯得(de)特別(bie)重(zhong)要(yao)，因為壓蓋(gai)(gai)(gai)必須對中。
