　　傳動形式多，但是渝中機械密封的更換(huan)工(gong)作大同小(xiao)異，首先拆前需(xu)確認電機處于檢修(xiu)狀態，擰下加油螺塞(sai)，用吸(xi)管(guan)把密封(feng)座腔內的潤滑油吸(xi)出。準(zhun)備好放(fang)置泵零件(jian)的工(gong)作臺(tai)及拆裝工(gong)具(ju)，切勿任意亂(luan)(luan)放(fang)亂(luan)(luan)用，避(bi)免(mian)碰壞泵的零部(bu)件(jian)。

　　拆對分式聯(lian)軸(zhou)器：先把聯(lian)軸(zhou)器的固定內(nei)六角螺釘擰下(xia)(xia)來，再(zai)輕輕把聯(lian)軸(zhou)器的一半(ban)(ban)從軸(zhou)上慢慢拉下(xia)(xia)，注(zhu)意不(bu)要掉了，再(zai)用(yong)梅花(hua)扳手擰下(xia)(xia)泵軸(zhou)吊緊螺栓和擋塊，讓(rang)葉輪慢慢下(xia)(xia)沉至泵體，然后拆下(xia)(xia)另(ling)外(wai)一半(ban)(ban)聯(lian)軸(zhou)器，拿下(xia)(xia)泵軸(zhou)擋圈(quan)。

　　拆卸渝中機械密封：抓(zhua)住密封(feng)彈簧順著泵軸往(wang)上(shang)提，就能拆下來了。

　　拆(chai)卸并(bing)清(qing)洗(xi)軸(zhou)(zhou)(zhou)承(cheng)座：先輕輕松動一下軸(zhou)(zhou)(zhou)承(cheng)座后(hou)用拆(chai)卸螺(luo)栓頂起軸(zhou)(zhou)(zhou)承(cheng)座，并(bing)且沿著泵軸(zhou)(zhou)(zhou)往上提而卸下，再用噴氣(qi)燃(ran)料清(qing)洗(xi)軸(zhou)(zhou)(zhou)承(cheng)及座，裝(zhuang)前(qian)晾干并(bing)涂抹少(shao)許(xu)20號機械油用來潤滑保護。

　　拆密封座(zuo)(zuo)：擰(ning)下密封座(zuo)(zuo)壓緊螺母，輕(qing)輕(qing)卸下密封座(zuo)(zuo)并清(qing)洗。

　　渝中機械密封裝配(pei)(pei)：在動(dong)、靜環(huan)(huan)(huan)鏡面上涂一層潔凈(jing)的20號潤滑(hua)油(you)，導軸承(cheng)座(zuo)也抹上潤滑(hua)油(you)，先把靜環(huan)(huan)(huan)輕(qing)(qing)輕(qing)(qing)定(ding)位裝入(ru)導軸承(cheng)座(zuo)，再在泵軸上抹上潤滑(hua)油(you)，把動(dong)環(huan)(huan)(huan)部分輕(qing)(qing)輕(qing)(qing)裝入(ru)泵軸上，用手(shou)輕(qing)(qing)推密(mi)封環(huan)(huan)(huan)應(ying)能(neng)伸縮自如，注意動(dong)、靜環(huan)(huan)(huan)部分的防(fang)轉部位需裝配(pei)(pei)到位。

　　裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)：在(zai)電機軸(zhou)頭上裝(zhuang)上擋(dang)圈，裝(zhuang)上一(yi)半聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)，再在(zai)泵軸(zhou)端(duan)和聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)槽內裝(zhuang)上擋(dang)塊并用梅(mei)花(hua)扳手擰緊螺栓；再裝(zhuang)上另一(yi)半聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)擰上內六角(jiao)螺釘。安裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)正確的檢查(cha)要求：對分式(shi)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)上下間隙(xi)需要均勻，用手盤(pan)動聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)幾(ji)圈檢查(cha)轉動的靈活(huo)性。

　　裝(zhuang)(zhuang)密(mi)封座(zuo)：先將密(mi)封座(zuo)裝(zhuang)(zhuang)入(ru)橡膠油封，再把密(mi)封座(zuo)裝(zhuang)(zhuang)入(ru)泵(beng)蓋(gai)(gai)并(bing)壓(ya)(ya)(ya)(ya)在軸(zhou)承座(zuo)上，擰緊螺母，確(que)保所(suo)有安(an)(an)裝(zhuang)(zhuang)螺釘(ding)緊固(gu)。當安(an)(an)裝(zhuang)(zhuang)螺釘(ding)被用作密(mi)封與軸(zhou)之間(jian)(jian)的驅(qu)動時，軸(zhou)應(ying)打埋頭孔來加固(gu)連接，緊固(gu)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)螺栓時應(ying)該平穩緊固(gu)，并(bing)且不要(yao)(yao)使壓(ya)(ya)(ya)(ya)蓋(gai)(gai)受彈力。在可(ke)能(neng)的地方使用4個以(yi)上螺釘(ding)的等間(jian)(jian)距壓(ya)(ya)(ya)(ya)蓋(gai)(gai)，緊固(gu)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)螺栓時，用塞(sai)尺(chi)檢查軸(zhou)與壓(ya)(ya)(ya)(ya)蓋(gai)(gai)之間(jian)(jian)的間(jian)(jian)隙，這在密(mi)封腔對(dui)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)不導向時，顯得特(te)別重要(yao)(yao)，因為(wei)壓(ya)(ya)(ya)(ya)蓋(gai)(gai)必須(xu)對(dui)中(zhong)。
