　　傳動形式多，但是成都機械密封的更換工(gong)作(zuo)(zuo)大同(tong)小(xiao)異，首先拆(chai)前需(xu)確認電機處(chu)于(yu)檢修狀態，擰下加油螺塞，用吸管把密封(feng)座腔內的潤滑油吸出。準備(bei)好放置泵(beng)(beng)零(ling)件的工(gong)作(zuo)(zuo)臺及拆(chai)裝工(gong)具(ju)，切勿任意(yi)亂放亂用，避免碰(peng)壞泵(beng)(beng)的零(ling)部件。

　　拆(chai)對分式聯軸(zhou)器：先把聯軸(zhou)器的(de)固(gu)定內六角螺釘擰下(xia)來，再(zai)輕輕把聯軸(zhou)器的(de)一(yi)半從軸(zhou)上慢(man)(man)慢(man)(man)拉(la)下(xia)，注意(yi)不要掉(diao)了，再(zai)用梅(mei)花扳手擰下(xia)泵軸(zhou)吊緊螺栓和(he)擋塊，讓葉輪(lun)慢(man)(man)慢(man)(man)下(xia)沉至泵體，然后拆(chai)下(xia)另外一(yi)半聯軸(zhou)器，拿下(xia)泵軸(zhou)擋圈。

　　拆卸成都機械密封：抓(zhua)住密封(feng)彈簧(huang)順著泵(beng)軸往上提，就(jiu)能拆(chai)下來(lai)了。

　　拆(chai)卸(xie)并清(qing)(qing)洗軸承座(zuo)：先輕輕松動一下(xia)軸承座(zuo)后(hou)用拆(chai)卸(xie)螺栓(shuan)頂起軸承座(zuo)，并且沿著泵軸往上提而卸(xie)下(xia)，再用噴氣燃料清(qing)(qing)洗軸承及座(zuo)，裝前(qian)晾干(gan)并涂抹少許20號機械油用來潤滑保護。

　　拆密封(feng)座(zuo)：擰下密封(feng)座(zuo)壓緊(jin)螺(luo)母，輕(qing)輕(qing)卸(xie)下密封(feng)座(zuo)并清洗。

　　成都機械密封裝配：在動、靜(jing)環鏡面上涂一層潔凈的20號潤滑油(you)，導軸(zhou)承座也抹上潤滑油(you)，先把(ba)靜(jing)環輕輕定(ding)位裝入導軸(zhou)承座，再在泵軸(zhou)上抹上潤滑油(you)，把(ba)動環部分(fen)輕輕裝入泵軸(zhou)上，用手輕推密(mi)封環應能伸縮自(zi)如，注意動、靜(jing)環部分(fen)的防轉部位需裝配到(dao)位。

　　裝(zhuang)聯(lian)(lian)軸器(qi)(qi)(qi)：在電機軸頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)圈(quan)，裝(zhuang)上(shang)(shang)一(yi)半聯(lian)(lian)軸器(qi)(qi)(qi)，再在泵軸端和聯(lian)(lian)軸器(qi)(qi)(qi)槽內裝(zhuang)上(shang)(shang)擋(dang)塊并用(yong)梅花(hua)扳手(shou)擰緊螺(luo)栓；再裝(zhuang)上(shang)(shang)另一(yi)半聯(lian)(lian)軸器(qi)(qi)(qi)擰上(shang)(shang)內六角螺(luo)釘(ding)。安裝(zhuang)聯(lian)(lian)軸器(qi)(qi)(qi)正確的檢查(cha)要求：對分式(shi)聯(lian)(lian)軸器(qi)(qi)(qi)上(shang)(shang)下間隙需要均勻，用(yong)手(shou)盤(pan)動(dong)聯(lian)(lian)軸器(qi)(qi)(qi)幾圈(quan)檢查(cha)轉(zhuan)動(dong)的靈活性。

　　裝(zhuang)(zhuang)密封座(zuo)：先將密封座(zuo)裝(zhuang)(zhuang)入(ru)橡膠(jiao)油封，再把密封座(zuo)裝(zhuang)(zhuang)入(ru)泵(beng)蓋(gai)并壓(ya)(ya)(ya)(ya)在軸(zhou)承座(zuo)上(shang)，擰緊螺(luo)母，確保所有(you)安裝(zhuang)(zhuang)螺(luo)釘(ding)緊固(gu)。當(dang)安裝(zhuang)(zhuang)螺(luo)釘(ding)被用作密封與(yu)軸(zhou)之(zhi)間(jian)的(de)驅動時，軸(zhou)應打埋頭孔來加(jia)固(gu)連接，緊固(gu)壓(ya)(ya)(ya)(ya)蓋(gai)螺(luo)栓時應該(gai)平穩(wen)緊固(gu)，并且不要使(shi)壓(ya)(ya)(ya)(ya)蓋(gai)受彈力。在可能的(de)地方(fang)使(shi)用4個以上(shang)螺(luo)釘(ding)的(de)等間(jian)距(ju)壓(ya)(ya)(ya)(ya)蓋(gai)，緊固(gu)壓(ya)(ya)(ya)(ya)蓋(gai)螺(luo)栓時，用塞尺檢查(cha)軸(zhou)與(yu)壓(ya)(ya)(ya)(ya)蓋(gai)之(zhi)間(jian)的(de)間(jian)隙，這在密封腔(qiang)對壓(ya)(ya)(ya)(ya)蓋(gai)不導向時，顯得特別重要，因(yin)為壓(ya)(ya)(ya)(ya)蓋(gai)必須(xu)對中。
