　　傳動形式多，但是昌圖機械密封的更換工(gong)作(zuo)大同(tong)小異，首先拆前需(xu)確認電機處于檢修(xiu)狀態(tai)，擰(ning)下加油(you)螺塞，用吸(xi)管把(ba)密封座腔(qiang)內的潤(run)滑(hua)油(you)吸(xi)出。準備好放置泵零(ling)(ling)件的工(gong)作(zuo)臺及(ji)拆裝工(gong)具，切勿(wu)任意亂(luan)放亂(luan)用，避(bi)免碰壞泵的零(ling)(ling)部(bu)件。

　　拆(chai)對分式聯(lian)軸(zhou)器：先把聯(lian)軸(zhou)器的固(gu)定內六角螺釘擰下(xia)來(lai)，再(zai)輕輕把聯(lian)軸(zhou)器的一半(ban)從(cong)軸(zhou)上慢(man)慢(man)拉下(xia)，注意不(bu)要掉了，再(zai)用梅花扳手擰下(xia)泵(beng)軸(zhou)吊緊螺栓(shuan)和擋塊，讓葉輪慢(man)慢(man)下(xia)沉(chen)至泵(beng)體，然后(hou)拆(chai)下(xia)另外一半(ban)聯(lian)軸(zhou)器，拿下(xia)泵(beng)軸(zhou)擋圈。

　　拆卸昌圖機械密封：抓住(zhu)密封彈(dan)簧順著泵軸往上提，就能(neng)拆(chai)下(xia)來了。

　　拆(chai)(chai)卸并清洗(xi)(xi)軸(zhou)承(cheng)座(zuo)：先輕輕松動一(yi)下(xia)軸(zhou)承(cheng)座(zuo)后用拆(chai)(chai)卸螺栓頂(ding)起軸(zhou)承(cheng)座(zuo)，并且沿(yan)著泵軸(zhou)往上提而卸下(xia)，再用噴(pen)氣燃料清洗(xi)(xi)軸(zhou)承(cheng)及座(zuo)，裝前晾(liang)干并涂(tu)抹(mo)少許20號機械油用來潤滑保護。

　　拆(chai)密封座(zuo)：擰下(xia)密封座(zuo)壓緊螺母，輕(qing)(qing)輕(qing)(qing)卸下(xia)密封座(zuo)并清洗(xi)。

　　昌圖機械密封裝(zhuang)配：在動、靜環(huan)鏡面上涂一層潔凈的20號(hao)潤滑(hua)油，導軸(zhou)(zhou)承座也抹上潤滑(hua)油，先把(ba)靜環(huan)輕輕定(ding)位(wei)裝(zhuang)入導軸(zhou)(zhou)承座，再在泵軸(zhou)(zhou)上抹上潤滑(hua)油，把(ba)動環(huan)部分(fen)輕輕裝(zhuang)入泵軸(zhou)(zhou)上，用手輕推密封環(huan)應能伸縮自(zi)如，注意動、靜環(huan)部分(fen)的防轉部位(wei)需裝(zhuang)配到位(wei)。

　　裝聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)：在電(dian)機軸(zhou)(zhou)(zhou)頭上(shang)(shang)(shang)裝上(shang)(shang)(shang)擋圈，裝上(shang)(shang)(shang)一(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)槽內裝上(shang)(shang)(shang)擋塊(kuai)并用梅花扳手(shou)擰緊螺(luo)栓；再裝上(shang)(shang)(shang)另(ling)一(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)擰上(shang)(shang)(shang)內六角螺(luo)釘。安裝聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)正確的(de)檢查要求：對(dui)分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)上(shang)(shang)(shang)下(xia)間隙(xi)需要均勻(yun)，用手(shou)盤動(dong)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)幾圈檢查轉(zhuan)動(dong)的(de)靈活性。

　　裝(zhuang)密封(feng)(feng)(feng)(feng)(feng)座：先將密封(feng)(feng)(feng)(feng)(feng)座裝(zhuang)入橡(xiang)膠油封(feng)(feng)(feng)(feng)(feng)，再把密封(feng)(feng)(feng)(feng)(feng)座裝(zhuang)入泵蓋(gai)(gai)并壓(ya)在(zai)軸承(cheng)座上(shang)，擰緊螺(luo)母(mu)，確保所(suo)有(you)安裝(zhuang)螺(luo)釘緊固(gu)。當安裝(zhuang)螺(luo)釘被用作密封(feng)(feng)(feng)(feng)(feng)與軸之間的驅(qu)動時(shi)，軸應打埋頭孔來加固(gu)連接，緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)栓時(shi)應該(gai)平穩(wen)緊固(gu)，并且(qie)不要使(shi)壓(ya)蓋(gai)(gai)受(shou)彈(dan)力。在(zai)可能的地方使(shi)用4個以上(shang)螺(luo)釘的等間距壓(ya)蓋(gai)(gai)，緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)栓時(shi)，用塞尺檢查(cha)軸與壓(ya)蓋(gai)(gai)之間的間隙，這在(zai)密封(feng)(feng)(feng)(feng)(feng)腔對壓(ya)蓋(gai)(gai)不導(dao)向時(shi)，顯(xian)得特別(bie)重要，因(yin)為壓(ya)蓋(gai)(gai)必須對中。
