　　傳動形式多，但是新絳機械密封的(de)更換(huan)工(gong)作大同小異，首先拆(chai)前(qian)需(xu)確認(ren)電機(ji)處于檢(jian)修狀(zhuang)態，擰下加油螺(luo)塞，用(yong)吸管把密(mi)封(feng)座腔內的(de)潤滑油吸出。準備好放置泵零(ling)件的(de)工(gong)作臺(tai)及拆(chai)裝工(gong)具，切(qie)勿任意亂放亂用(yong)，避免碰(peng)壞(huai)泵的(de)零(ling)部件。

　　拆對分式聯(lian)軸(zhou)器：先把(ba)聯(lian)軸(zhou)器的固定內六角螺(luo)釘擰下來，再輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)器的一(yi)(yi)半從軸(zhou)上(shang)慢慢拉下，注意不要掉(diao)了，再用梅花(hua)扳(ban)手擰下泵(beng)軸(zhou)吊緊螺(luo)栓和擋塊(kuai)，讓葉輪(lun)慢慢下沉至泵(beng)體，然后拆下另(ling)外一(yi)(yi)半聯(lian)軸(zhou)器，拿下泵(beng)軸(zhou)擋圈。

　　拆卸新絳機械密封：抓住密封彈簧順著(zhu)泵軸往上提，就能拆下來了(le)。

　　拆(chai)卸并清洗(xi)軸(zhou)承(cheng)(cheng)(cheng)座：先輕輕松動一下(xia)軸(zhou)承(cheng)(cheng)(cheng)座后用(yong)拆(chai)卸螺栓頂起軸(zhou)承(cheng)(cheng)(cheng)座，并且沿著泵(beng)軸(zhou)往(wang)上(shang)提而卸下(xia)，再用(yong)噴氣(qi)燃(ran)料清洗(xi)軸(zhou)承(cheng)(cheng)(cheng)及(ji)座，裝前晾干并涂抹少許20號(hao)機(ji)械油用(yong)來潤滑保護。

　　拆密封座(zuo)：擰下(xia)密封座(zuo)壓緊螺母(mu)，輕(qing)輕(qing)卸下(xia)密封座(zuo)并(bing)清洗。

　　新絳機械密封裝配：在動、靜環鏡(jing)面上(shang)涂一層潔(jie)凈的20號潤(run)滑油，導軸承(cheng)座(zuo)也抹上(shang)潤(run)滑油，先把靜環輕(qing)(qing)(qing)輕(qing)(qing)(qing)定位(wei)裝入導軸承(cheng)座(zuo)，再在泵軸上(shang)抹上(shang)潤(run)滑油，把動環部分輕(qing)(qing)(qing)輕(qing)(qing)(qing)裝入泵軸上(shang)，用手輕(qing)(qing)(qing)推密封(feng)環應能伸縮自如(ru)，注意動、靜環部分的防轉部位(wei)需裝配到位(wei)。

　　裝(zhuang)聯(lian)(lian)軸(zhou)器：在電(dian)機軸(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋圈，裝(zhuang)上(shang)(shang)一(yi)半聯(lian)(lian)軸(zhou)器，再在泵軸(zhou)端和聯(lian)(lian)軸(zhou)器槽內(nei)裝(zhuang)上(shang)(shang)擋塊并用(yong)梅花扳手擰緊(jin)螺栓；再裝(zhuang)上(shang)(shang)另一(yi)半聯(lian)(lian)軸(zhou)器擰上(shang)(shang)內(nei)六角螺釘(ding)。安(an)裝(zhuang)聯(lian)(lian)軸(zhou)器正確的檢(jian)查要求：對分(fen)式聯(lian)(lian)軸(zhou)器上(shang)(shang)下間(jian)隙需要均勻，用(yong)手盤動聯(lian)(lian)軸(zhou)器幾圈檢(jian)查轉動的靈活(huo)性。

　　裝(zhuang)(zhuang)密(mi)(mi)封座：先將密(mi)(mi)封座裝(zhuang)(zhuang)入橡膠油封，再把密(mi)(mi)封座裝(zhuang)(zhuang)入泵蓋(gai)(gai)(gai)并(bing)壓(ya)(ya)在軸承座上(shang)，擰(ning)緊螺母，確(que)保所有安裝(zhuang)(zhuang)螺釘緊固(gu)。當安裝(zhuang)(zhuang)螺釘被用(yong)作密(mi)(mi)封與(yu)軸之間的(de)驅(qu)動時(shi)，軸應(ying)打埋(mai)頭孔來加固(gu)連接，緊固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺栓時(shi)應(ying)該(gai)平穩緊固(gu)，并(bing)且不要(yao)使壓(ya)(ya)蓋(gai)(gai)(gai)受彈力。在可能的(de)地(di)方使用(yong)4個以上(shang)螺釘的(de)等間距壓(ya)(ya)蓋(gai)(gai)(gai)，緊固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺栓時(shi)，用(yong)塞尺檢查(cha)軸與(yu)壓(ya)(ya)蓋(gai)(gai)(gai)之間的(de)間隙，這在密(mi)(mi)封腔對(dui)壓(ya)(ya)蓋(gai)(gai)(gai)不導向時(shi)，顯得特(te)別重要(yao)，因為壓(ya)(ya)蓋(gai)(gai)(gai)必(bi)須對(dui)中。
