　　傳動形式多，但是雙臺子機械密封的(de)更換工作(zuo)大(da)同小異，首先拆前(qian)需確認電機處(chu)于檢修(xiu)狀(zhuang)態，擰下加(jia)油螺塞，用(yong)吸(xi)管把密封座腔內的(de)潤(run)滑油吸(xi)出。準備好(hao)放(fang)置泵(beng)零(ling)件的(de)工作(zuo)臺及拆裝工具，切勿任(ren)意亂(luan)放(fang)亂(luan)用(yong)，避(bi)免(mian)碰壞泵(beng)的(de)零(ling)部件。

　　拆對分(fen)式聯(lian)(lian)軸(zhou)(zhou)器(qi)：先(xian)把(ba)聯(lian)(lian)軸(zhou)(zhou)器(qi)的固(gu)定內六角螺(luo)釘(ding)擰下(xia)來，再輕輕把(ba)聯(lian)(lian)軸(zhou)(zhou)器(qi)的一(yi)半從軸(zhou)(zhou)上(shang)慢(man)慢(man)拉(la)下(xia)，注(zhu)意不要掉了，再用梅(mei)花扳(ban)手擰下(xia)泵(beng)軸(zhou)(zhou)吊緊(jin)螺(luo)栓和擋塊，讓葉輪慢(man)慢(man)下(xia)沉至(zhi)泵(beng)體，然后(hou)拆下(xia)另外(wai)一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)，拿下(xia)泵(beng)軸(zhou)(zhou)擋圈。

　　拆卸雙臺子機械密封：抓住密封彈(dan)簧(huang)順著泵軸往上提，就能拆下來了。

　　拆(chai)卸(xie)并清(qing)洗(xi)軸(zhou)承(cheng)座：先輕輕松動一下軸(zhou)承(cheng)座后(hou)用拆(chai)卸(xie)螺栓(shuan)頂起軸(zhou)承(cheng)座，并且沿著泵軸(zhou)往上提而卸(xie)下，再用噴氣燃(ran)料清(qing)洗(xi)軸(zhou)承(cheng)及(ji)座，裝(zhuang)前晾干并涂抹(mo)少許20號機(ji)械油用來潤滑保護。

　　拆密(mi)封(feng)座：擰下密(mi)封(feng)座壓緊螺母(mu)，輕(qing)輕(qing)卸下密(mi)封(feng)座并清洗(xi)。

　　雙臺子機械密封裝(zhuang)配：在動(dong)(dong)、靜(jing)環鏡面上(shang)(shang)涂一層潔凈的(de)20號(hao)潤(run)滑(hua)油(you)，導(dao)軸(zhou)承座也抹上(shang)(shang)潤(run)滑(hua)油(you)，先(xian)把(ba)靜(jing)環輕輕定位裝(zhuang)入導(dao)軸(zhou)承座，再在泵軸(zhou)上(shang)(shang)抹上(shang)(shang)潤(run)滑(hua)油(you)，把(ba)動(dong)(dong)環部分輕輕裝(zhuang)入泵軸(zhou)上(shang)(shang)，用手輕推(tui)密封環應能伸縮自如，注意動(dong)(dong)、靜(jing)環部分的(de)防(fang)轉部位需裝(zhuang)配到位。

　　裝(zhuang)聯(lian)軸器(qi)：在電(dian)機軸頭上(shang)裝(zhuang)上(shang)擋圈(quan)，裝(zhuang)上(shang)一(yi)半聯(lian)軸器(qi)，再(zai)在泵軸端(duan)和聯(lian)軸器(qi)槽內(nei)裝(zhuang)上(shang)擋塊并用(yong)梅花扳手擰(ning)緊螺(luo)栓；再(zai)裝(zhuang)上(shang)另一(yi)半聯(lian)軸器(qi)擰(ning)上(shang)內(nei)六(liu)角螺(luo)釘。安裝(zhuang)聯(lian)軸器(qi)正確的檢查(cha)要求(qiu)：對分式聯(lian)軸器(qi)上(shang)下間(jian)隙需要均勻(yun)，用(yong)手盤動聯(lian)軸器(qi)幾圈(quan)檢查(cha)轉動的靈活性。

　　裝(zhuang)密(mi)封(feng)(feng)(feng)座：先將密(mi)封(feng)(feng)(feng)座裝(zhuang)入(ru)橡膠(jiao)油封(feng)(feng)(feng)，再把密(mi)封(feng)(feng)(feng)座裝(zhuang)入(ru)泵蓋(gai)并(bing)壓(ya)在(zai)軸承(cheng)座上，擰緊螺(luo)(luo)母，確保所有安裝(zhuang)螺(luo)(luo)釘(ding)緊固(gu)(gu)。當安裝(zhuang)螺(luo)(luo)釘(ding)被(bei)用作密(mi)封(feng)(feng)(feng)與軸之間(jian)的(de)驅動時(shi)(shi)，軸應打埋頭(tou)孔來加固(gu)(gu)連接(jie)，緊固(gu)(gu)壓(ya)蓋(gai)螺(luo)(luo)栓時(shi)(shi)應該平穩緊固(gu)(gu)，并(bing)且(qie)不(bu)要使(shi)壓(ya)蓋(gai)受彈力。在(zai)可能的(de)地方使(shi)用4個以上螺(luo)(luo)釘(ding)的(de)等間(jian)距壓(ya)蓋(gai)，緊固(gu)(gu)壓(ya)蓋(gai)螺(luo)(luo)栓時(shi)(shi)，用塞尺檢查軸與壓(ya)蓋(gai)之間(jian)的(de)間(jian)隙，這在(zai)密(mi)封(feng)(feng)(feng)腔對壓(ya)蓋(gai)不(bu)導向時(shi)(shi)，顯得(de)特別重要，因為壓(ya)蓋(gai)必須對中。
