　　傳動形式多，但是雙流機械密封的(de)(de)更換(huan)工作大(da)同小異(yi)，首先拆前需(xu)確認電機處于檢修狀態(tai)，擰下(xia)加油螺塞(sai)，用吸管把密(mi)封座腔(qiang)內的(de)(de)潤滑油吸出(chu)。準備好放置泵零(ling)件的(de)(de)工作臺及拆裝工具，切勿(wu)任意亂放亂用，避免(mian)碰壞泵的(de)(de)零(ling)部(bu)件。

　　拆(chai)(chai)對分式(shi)聯(lian)軸(zhou)(zhou)(zhou)器：先把聯(lian)軸(zhou)(zhou)(zhou)器的固定內六角螺(luo)(luo)釘擰(ning)下來(lai)，再輕輕把聯(lian)軸(zhou)(zhou)(zhou)器的一半從軸(zhou)(zhou)(zhou)上慢慢拉下，注意(yi)不要(yao)掉了，再用梅(mei)花扳手(shou)擰(ning)下泵軸(zhou)(zhou)(zhou)吊緊螺(luo)(luo)栓和擋(dang)塊，讓葉輪(lun)慢慢下沉至泵體，然后拆(chai)(chai)下另外一半聯(lian)軸(zhou)(zhou)(zhou)器，拿下泵軸(zhou)(zhou)(zhou)擋(dang)圈。

　　拆卸雙流機械密封：抓(zhua)住(zhu)密(mi)封彈簧順著泵軸往上提(ti)，就能(neng)拆(chai)下(xia)來了。

　　拆卸并清(qing)洗軸(zhou)承(cheng)(cheng)座：先(xian)輕輕松動一下軸(zhou)承(cheng)(cheng)座后用(yong)拆卸螺栓頂起軸(zhou)承(cheng)(cheng)座，并且沿(yan)著泵(beng)軸(zhou)往上提而卸下，再(zai)用(yong)噴(pen)氣燃料清(qing)洗軸(zhou)承(cheng)(cheng)及座，裝(zhuang)前晾干并涂(tu)抹少許20號(hao)機械油用(yong)來潤滑保護。

　　拆密(mi)封(feng)座：擰下密(mi)封(feng)座壓(ya)緊螺母(mu)，輕輕卸下密(mi)封(feng)座并(bing)清洗。

　　雙流機械密封裝(zhuang)(zhuang)配：在動(dong)、靜(jing)環(huan)(huan)(huan)鏡(jing)面上涂一層(ceng)潔(jie)凈(jing)的20號潤(run)滑油，導軸承座(zuo)也抹上潤(run)滑油，先把(ba)靜(jing)環(huan)(huan)(huan)輕輕定位(wei)裝(zhuang)(zhuang)入導軸承座(zuo)，再在泵軸上抹上潤(run)滑油，把(ba)動(dong)環(huan)(huan)(huan)部(bu)分(fen)輕輕裝(zhuang)(zhuang)入泵軸上，用(yong)手輕推(tui)密封(feng)環(huan)(huan)(huan)應(ying)能伸縮自如，注意動(dong)、靜(jing)環(huan)(huan)(huan)部(bu)分(fen)的防(fang)轉部(bu)位(wei)需裝(zhuang)(zhuang)配到位(wei)。

　　裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)：在(zai)電機軸(zhou)(zhou)頭(tou)上(shang)裝(zhuang)(zhuang)上(shang)擋圈(quan)，裝(zhuang)(zhuang)上(shang)一半聯(lian)軸(zhou)(zhou)器(qi)，再(zai)(zai)在(zai)泵軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)槽內裝(zhuang)(zhuang)上(shang)擋塊并用(yong)(yong)梅花扳手擰(ning)緊(jin)螺栓；再(zai)(zai)裝(zhuang)(zhuang)上(shang)另(ling)一半聯(lian)軸(zhou)(zhou)器(qi)擰(ning)上(shang)內六(liu)角螺釘。安(an)裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)正確的(de)檢(jian)查要求：對分式聯(lian)軸(zhou)(zhou)器(qi)上(shang)下間隙需要均勻(yun)，用(yong)(yong)手盤動(dong)聯(lian)軸(zhou)(zhou)器(qi)幾圈(quan)檢(jian)查轉動(dong)的(de)靈活(huo)性。

　　裝(zhuang)密(mi)封座(zuo)：先將密(mi)封座(zuo)裝(zhuang)入(ru)橡膠油封，再(zai)把(ba)密(mi)封座(zuo)裝(zhuang)入(ru)泵蓋(gai)(gai)(gai)(gai)(gai)并壓(ya)在軸(zhou)承座(zuo)上(shang)(shang)，擰緊螺(luo)(luo)母，確保所有(you)安裝(zhuang)螺(luo)(luo)釘(ding)(ding)緊固(gu)(gu)(gu)。當安裝(zhuang)螺(luo)(luo)釘(ding)(ding)被用作密(mi)封與軸(zhou)之間(jian)的(de)驅動時，軸(zhou)應打(da)埋(mai)頭孔來(lai)加固(gu)(gu)(gu)連(lian)接，緊固(gu)(gu)(gu)壓(ya)蓋(gai)(gai)(gai)(gai)(gai)螺(luo)(luo)栓時應該平穩緊固(gu)(gu)(gu)，并且不要使壓(ya)蓋(gai)(gai)(gai)(gai)(gai)受彈力。在可(ke)能的(de)地方使用4個(ge)以上(shang)(shang)螺(luo)(luo)釘(ding)(ding)的(de)等間(jian)距壓(ya)蓋(gai)(gai)(gai)(gai)(gai)，緊固(gu)(gu)(gu)壓(ya)蓋(gai)(gai)(gai)(gai)(gai)螺(luo)(luo)栓時，用塞尺檢查軸(zhou)與壓(ya)蓋(gai)(gai)(gai)(gai)(gai)之間(jian)的(de)間(jian)隙，這在密(mi)封腔對壓(ya)蓋(gai)(gai)(gai)(gai)(gai)不導(dao)向時，顯(xian)得特(te)別重要，因為壓(ya)蓋(gai)(gai)(gai)(gai)(gai)必須對中。
