　　傳動形式多，但是上安鄉機械密封的(de)更(geng)換工作大同小(xiao)異，首(shou)先拆前需確認電機(ji)處于檢修狀態，擰下(xia)加(jia)油螺塞，用(yong)吸(xi)管把(ba)密(mi)封座腔內(nei)的(de)潤滑油吸(xi)出。準備好放置泵零件(jian)的(de)工作臺及拆裝工具(ju)，切(qie)勿任意亂(luan)放亂(luan)用(yong)，避免碰(peng)壞泵的(de)零部件(jian)。

　　拆對(dui)分(fen)式聯(lian)軸(zhou)器(qi)：先(xian)把聯(lian)軸(zhou)器(qi)的(de)固(gu)定內六角螺釘擰(ning)下(xia)(xia)來，再(zai)(zai)輕輕把聯(lian)軸(zhou)器(qi)的(de)一半(ban)從軸(zhou)上慢(man)慢(man)拉下(xia)(xia)，注意(yi)不(bu)要掉了，再(zai)(zai)用(yong)梅花扳手擰(ning)下(xia)(xia)泵軸(zhou)吊(diao)緊螺栓和擋塊，讓葉輪慢(man)慢(man)下(xia)(xia)沉至(zhi)泵體，然(ran)后(hou)拆下(xia)(xia)另外一半(ban)聯(lian)軸(zhou)器(qi)，拿下(xia)(xia)泵軸(zhou)擋圈(quan)。

　　拆卸上安鄉機械密封：抓(zhua)住密封(feng)彈簧順著泵軸往(wang)上(shang)提，就(jiu)能拆下來了。

　　拆(chai)(chai)卸(xie)并清洗軸(zhou)承座(zuo)：先輕輕松動(dong)一下(xia)軸(zhou)承座(zuo)后用拆(chai)(chai)卸(xie)螺栓頂起(qi)軸(zhou)承座(zuo)，并且沿(yan)著泵軸(zhou)往上提而卸(xie)下(xia)，再用噴(pen)氣燃料清洗軸(zhou)承及座(zuo)，裝前晾干并涂抹(mo)少許(xu)20號機械油用來潤滑保護。

　　拆密封座：擰(ning)下(xia)密封座壓(ya)緊螺(luo)母，輕輕卸下(xia)密封座并清洗。

　　上安鄉機械密封裝(zhuang)(zhuang)配：在(zai)動(dong)、靜環(huan)鏡面上(shang)(shang)涂(tu)一層潔(jie)凈的20號潤滑油(you)，導(dao)軸承(cheng)座也抹(mo)上(shang)(shang)潤滑油(you)，先把靜環(huan)輕輕定位(wei)(wei)裝(zhuang)(zhuang)入(ru)導(dao)軸承(cheng)座，再(zai)在(zai)泵軸上(shang)(shang)抹(mo)上(shang)(shang)潤滑油(you)，把動(dong)環(huan)部(bu)分輕輕裝(zhuang)(zhuang)入(ru)泵軸上(shang)(shang)，用手輕推密封環(huan)應能伸縮(suo)自如，注意動(dong)、靜環(huan)部(bu)分的防(fang)轉部(bu)位(wei)(wei)需裝(zhuang)(zhuang)配到位(wei)(wei)。

　　裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器：在電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)(shang)(shang)裝(zhuang)上(shang)(shang)(shang)(shang)擋圈(quan)，裝(zhuang)上(shang)(shang)(shang)(shang)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器，再在泵軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器槽內裝(zhuang)上(shang)(shang)(shang)(shang)擋塊并用梅花扳(ban)手(shou)擰(ning)緊螺栓；再裝(zhuang)上(shang)(shang)(shang)(shang)另一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器擰(ning)上(shang)(shang)(shang)(shang)內六(liu)角螺釘。安裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器正(zheng)確的檢查(cha)要(yao)求(qiu)：對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器上(shang)(shang)(shang)(shang)下(xia)間隙需(xu)要(yao)均勻(yun)，用手(shou)盤動(dong)聯(lian)(lian)軸(zhou)(zhou)(zhou)器幾圈(quan)檢查(cha)轉(zhuan)動(dong)的靈活性。

　　裝(zhuang)(zhuang)密(mi)封座(zuo)(zuo)：先將密(mi)封座(zuo)(zuo)裝(zhuang)(zhuang)入(ru)橡(xiang)膠油封，再把密(mi)封座(zuo)(zuo)裝(zhuang)(zhuang)入(ru)泵(beng)蓋(gai)并(bing)(bing)壓(ya)在軸(zhou)承座(zuo)(zuo)上，擰緊(jin)螺(luo)(luo)母，確保(bao)所有安(an)裝(zhuang)(zhuang)螺(luo)(luo)釘緊(jin)固。當安(an)裝(zhuang)(zhuang)螺(luo)(luo)釘被用(yong)作密(mi)封與軸(zhou)之(zhi)間的驅動時，軸(zhou)應(ying)打埋頭孔來加固連接(jie)，緊(jin)固壓(ya)蓋(gai)螺(luo)(luo)栓時應(ying)該平穩緊(jin)固，并(bing)(bing)且不(bu)要(yao)使壓(ya)蓋(gai)受(shou)彈力。在可能的地方(fang)使用(yong)4個以上螺(luo)(luo)釘的等間距壓(ya)蓋(gai)，緊(jin)固壓(ya)蓋(gai)螺(luo)(luo)栓時，用(yong)塞(sai)尺檢查(cha)軸(zhou)與壓(ya)蓋(gai)之(zhi)間的間隙，這(zhe)在密(mi)封腔對(dui)壓(ya)蓋(gai)不(bu)導向時，顯得特別重要(yao)，因為壓(ya)蓋(gai)必須(xu)對(dui)中。
