　　傳動形式多，但是定襄機械密封的更換工作(zuo)大同(tong)小(xiao)異，首先拆前需確認電機(ji)處于檢修狀態，擰下加(jia)油螺塞，用(yong)吸(xi)管把密封座腔內的潤滑油吸(xi)出。準備好放置泵零件的工作(zuo)臺及(ji)拆裝工具，切勿任意亂放亂用(yong)，避免碰壞泵的零部(bu)件。

　　拆(chai)(chai)對分式聯(lian)軸(zhou)(zhou)器(qi)(qi)：先把聯(lian)軸(zhou)(zhou)器(qi)(qi)的固定(ding)內六角螺(luo)釘擰(ning)下(xia)(xia)來，再(zai)輕輕把聯(lian)軸(zhou)(zhou)器(qi)(qi)的一半(ban)(ban)從(cong)軸(zhou)(zhou)上慢(man)慢(man)拉(la)下(xia)(xia)，注意不要(yao)掉(diao)了(le)，再(zai)用(yong)梅花扳手(shou)擰(ning)下(xia)(xia)泵軸(zhou)(zhou)吊(diao)緊螺(luo)栓和(he)擋塊(kuai)，讓葉輪慢(man)慢(man)下(xia)(xia)沉至泵體，然后拆(chai)(chai)下(xia)(xia)另外一半(ban)(ban)聯(lian)軸(zhou)(zhou)器(qi)(qi)，拿下(xia)(xia)泵軸(zhou)(zhou)擋圈。

　　拆卸定襄機械密封：抓住(zhu)密封彈簧(huang)順著泵軸往上提，就能拆下(xia)來了。

　　拆卸并(bing)清洗軸(zhou)承(cheng)(cheng)座：先輕(qing)輕(qing)松動(dong)一(yi)下(xia)軸(zhou)承(cheng)(cheng)座后用(yong)(yong)拆卸螺栓(shuan)頂(ding)起軸(zhou)承(cheng)(cheng)座，并(bing)且(qie)沿著泵軸(zhou)往上提(ti)而(er)卸下(xia)，再用(yong)(yong)噴氣燃料(liao)清洗軸(zhou)承(cheng)(cheng)及座，裝前(qian)晾干并(bing)涂抹少許20號機械油用(yong)(yong)來(lai)潤滑(hua)保護。

　　拆密(mi)封(feng)座(zuo)：擰(ning)下(xia)(xia)密(mi)封(feng)座(zuo)壓緊(jin)螺母(mu)，輕(qing)輕(qing)卸下(xia)(xia)密(mi)封(feng)座(zuo)并(bing)清(qing)洗(xi)。

　　定襄機械密封裝(zhuang)(zhuang)配：在動(dong)(dong)、靜環(huan)鏡面上(shang)涂一(yi)層潔凈的20號潤(run)滑(hua)油(you)(you)(you)，導(dao)軸承座(zuo)也抹上(shang)潤(run)滑(hua)油(you)(you)(you)，先把靜環(huan)輕輕定位裝(zhuang)(zhuang)入導(dao)軸承座(zuo)，再在泵軸上(shang)抹上(shang)潤(run)滑(hua)油(you)(you)(you)，把動(dong)(dong)環(huan)部分輕輕裝(zhuang)(zhuang)入泵軸上(shang)，用手輕推密封(feng)環(huan)應能伸(shen)縮自(zi)如，注意動(dong)(dong)、靜環(huan)部分的防轉部位需(xu)裝(zhuang)(zhuang)配到位。

　　裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)(zhou)頭(tou)上裝(zhuang)上擋圈，裝(zhuang)上一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)，再(zai)在泵(beng)軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)槽內裝(zhuang)上擋塊(kuai)并用(yong)梅花扳手(shou)擰(ning)緊(jin)螺栓；再(zai)裝(zhuang)上另(ling)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)擰(ning)上內六角螺釘(ding)。安裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)正(zheng)確(que)的檢查要(yao)求：對(dui)分式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)上下間(jian)隙需要(yao)均勻，用(yong)手(shou)盤動(dong)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈檢查轉動(dong)的靈活性。

　　裝(zhuang)密(mi)封(feng)(feng)(feng)座(zuo)(zuo)：先將(jiang)密(mi)封(feng)(feng)(feng)座(zuo)(zuo)裝(zhuang)入橡(xiang)膠油封(feng)(feng)(feng)，再把密(mi)封(feng)(feng)(feng)座(zuo)(zuo)裝(zhuang)入泵(beng)蓋(gai)并壓(ya)(ya)在(zai)軸承(cheng)座(zuo)(zuo)上(shang)，擰緊(jin)(jin)螺(luo)母，確保所(suo)有安裝(zhuang)螺(luo)釘(ding)緊(jin)(jin)固(gu)。當安裝(zhuang)螺(luo)釘(ding)被用(yong)作(zuo)密(mi)封(feng)(feng)(feng)與軸之(zhi)間(jian)的驅動時，軸應打埋頭孔(kong)來加固(gu)連接，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時應該(gai)平穩(wen)緊(jin)(jin)固(gu)，并且不要使壓(ya)(ya)蓋(gai)受彈力。在(zai)可能的地方(fang)使用(yong)4個以(yi)上(shang)螺(luo)釘(ding)的等(deng)間(jian)距壓(ya)(ya)蓋(gai)，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時，用(yong)塞尺(chi)檢查軸與壓(ya)(ya)蓋(gai)之(zhi)間(jian)的間(jian)隙，這在(zai)密(mi)封(feng)(feng)(feng)腔對壓(ya)(ya)蓋(gai)不導向時，顯得特別重要，因為壓(ya)(ya)蓋(gai)必(bi)須對中。
