　　傳動形式多，但是青田機械密封的更換(huan)工作大(da)同小異，首先(xian)拆前需確認電機處于檢修狀(zhuang)態，擰下(xia)加(jia)油(you)螺塞，用(yong)吸管把密封座(zuo)腔內(nei)的潤滑油(you)吸出。準備好放置泵零件的工作臺及拆裝工具，切勿任意亂(luan)(luan)放亂(luan)(luan)用(yong)，避免碰壞泵的零部件。

　　拆對分式(shi)聯軸器(qi)(qi)：先把(ba)聯軸器(qi)(qi)的固定內(nei)六角螺(luo)釘擰下(xia)(xia)(xia)來，再輕輕把(ba)聯軸器(qi)(qi)的一半從軸上慢(man)慢(man)拉(la)下(xia)(xia)(xia)，注意(yi)不要掉了(le)，再用梅花扳手擰下(xia)(xia)(xia)泵軸吊緊螺(luo)栓和擋(dang)塊，讓葉輪慢(man)慢(man)下(xia)(xia)(xia)沉至泵體，然后(hou)拆下(xia)(xia)(xia)另外一半聯軸器(qi)(qi)，拿下(xia)(xia)(xia)泵軸擋(dang)圈。

　　拆卸青田機械密封：抓住密封彈簧順著泵軸往上提，就能拆下來了。

　　拆(chai)卸并清洗(xi)軸承座：先輕輕松(song)動一下軸承座后用拆(chai)卸螺栓頂(ding)起軸承座，并且沿著泵軸往上提而卸下，再用噴氣(qi)燃料清洗(xi)軸承及座，裝(zhuang)前晾(liang)干(gan)并涂(tu)抹少許20號機械油(you)用來潤滑(hua)保(bao)護。

　　拆密(mi)(mi)封(feng)座(zuo)(zuo)：擰(ning)下(xia)密(mi)(mi)封(feng)座(zuo)(zuo)壓(ya)緊螺母，輕(qing)輕(qing)卸下(xia)密(mi)(mi)封(feng)座(zuo)(zuo)并清洗。

　　青田機械密封裝(zhuang)(zhuang)配(pei)：在動(dong)、靜環鏡面上涂一層潔凈的20號(hao)潤滑(hua)(hua)油，導(dao)軸承(cheng)座也抹上潤滑(hua)(hua)油，先(xian)把靜環輕輕定位(wei)裝(zhuang)(zhuang)入導(dao)軸承(cheng)座，再在泵軸上抹上潤滑(hua)(hua)油，把動(dong)環部分輕輕裝(zhuang)(zhuang)入泵軸上，用手輕推密封(feng)環應能伸縮自(zi)如，注意動(dong)、靜環部分的防轉部位(wei)需裝(zhuang)(zhuang)配(pei)到位(wei)。

　　裝(zhuang)聯軸(zhou)(zhou)器(qi)：在電(dian)機軸(zhou)(zhou)頭上(shang)(shang)(shang)裝(zhuang)上(shang)(shang)(shang)擋(dang)(dang)圈，裝(zhuang)上(shang)(shang)(shang)一半(ban)聯軸(zhou)(zhou)器(qi)，再在泵(beng)軸(zhou)(zhou)端和聯軸(zhou)(zhou)器(qi)槽(cao)內裝(zhuang)上(shang)(shang)(shang)擋(dang)(dang)塊并用(yong)梅花(hua)扳(ban)手(shou)擰緊螺(luo)栓；再裝(zhuang)上(shang)(shang)(shang)另一半(ban)聯軸(zhou)(zhou)器(qi)擰上(shang)(shang)(shang)內六角螺(luo)釘(ding)。安裝(zhuang)聯軸(zhou)(zhou)器(qi)正(zheng)確的(de)檢查要(yao)求：對分(fen)式聯軸(zhou)(zhou)器(qi)上(shang)(shang)(shang)下間隙需要(yao)均勻，用(yong)手(shou)盤動聯軸(zhou)(zhou)器(qi)幾圈檢查轉動的(de)靈活性。

　　裝(zhuang)密封(feng)座：先將密封(feng)座裝(zhuang)入橡膠油封(feng)，再(zai)把密封(feng)座裝(zhuang)入泵蓋(gai)(gai)(gai)并壓(ya)(ya)在(zai)(zai)軸承座上(shang)，擰緊(jin)螺(luo)母(mu)，確保(bao)所有(you)安(an)(an)裝(zhuang)螺(luo)釘緊(jin)固(gu)。當安(an)(an)裝(zhuang)螺(luo)釘被用(yong)(yong)作(zuo)密封(feng)與(yu)軸之(zhi)間(jian)的(de)(de)驅動時(shi)(shi)，軸應(ying)打埋頭孔來加(jia)固(gu)連(lian)接，緊(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓時(shi)(shi)應(ying)該(gai)平(ping)穩緊(jin)固(gu)，并且不(bu)要(yao)使(shi)壓(ya)(ya)蓋(gai)(gai)(gai)受(shou)彈力。在(zai)(zai)可能的(de)(de)地(di)方使(shi)用(yong)(yong)4個以上(shang)螺(luo)釘的(de)(de)等間(jian)距壓(ya)(ya)蓋(gai)(gai)(gai)，緊(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓時(shi)(shi)，用(yong)(yong)塞尺檢查軸與(yu)壓(ya)(ya)蓋(gai)(gai)(gai)之(zhi)間(jian)的(de)(de)間(jian)隙，這在(zai)(zai)密封(feng)腔對壓(ya)(ya)蓋(gai)(gai)(gai)不(bu)導向(xiang)時(shi)(shi)，顯得特(te)別(bie)重(zhong)要(yao)，因(yin)為壓(ya)(ya)蓋(gai)(gai)(gai)必須對中。
