　　傳動形式多，但是頭屯河機械密封的(de)(de)更換工作大同小異，首先拆前需確認電機處于檢修狀態，擰下加(jia)油(you)螺(luo)塞，用(yong)吸(xi)管把密封座腔內的(de)(de)潤(run)滑油(you)吸(xi)出。準備(bei)好放(fang)置泵零件(jian)的(de)(de)工作臺及拆裝工具，切(qie)勿任意亂放(fang)亂用(yong)，避免碰壞泵的(de)(de)零部件(jian)。

　　拆(chai)對分式聯軸(zhou)(zhou)(zhou)器(qi)：先把聯軸(zhou)(zhou)(zhou)器(qi)的固定內六角螺釘擰下來，再(zai)(zai)輕輕把聯軸(zhou)(zhou)(zhou)器(qi)的一半從(cong)軸(zhou)(zhou)(zhou)上(shang)慢(man)慢(man)拉下，注(zhu)意不要掉了(le)，再(zai)(zai)用梅花(hua)扳手擰下泵(beng)軸(zhou)(zhou)(zhou)吊緊(jin)螺栓和擋塊，讓葉輪慢(man)慢(man)下沉至泵(beng)體，然后(hou)拆(chai)下另外一半聯軸(zhou)(zhou)(zhou)器(qi)，拿下泵(beng)軸(zhou)(zhou)(zhou)擋圈。

　　拆卸頭屯河機械密封：抓(zhua)住密封彈(dan)簧順著泵軸往上(shang)提，就能(neng)拆下(xia)來了。

　　拆卸并(bing)清洗軸承(cheng)座(zuo)：先輕輕松動(dong)一(yi)下(xia)軸承(cheng)座(zuo)后用(yong)(yong)拆卸螺栓頂起軸承(cheng)座(zuo)，并(bing)且沿著泵軸往上(shang)提而卸下(xia)，再用(yong)(yong)噴氣(qi)燃料清洗軸承(cheng)及座(zuo)，裝前晾干并(bing)涂抹少許20號機(ji)械油用(yong)(yong)來潤滑(hua)保護(hu)。

　　拆(chai)密封(feng)座：擰下密封(feng)座壓緊(jin)螺母，輕輕卸下密封(feng)座并清洗。

　　頭屯河機械密封裝配：在動、靜(jing)環鏡面上涂一層潔凈的20號潤滑(hua)油(you)，導軸承座也抹(mo)上潤滑(hua)油(you)，先把靜(jing)環輕(qing)輕(qing)定位(wei)裝入(ru)導軸承座，再在泵軸上抹(mo)上潤滑(hua)油(you)，把動環部分輕(qing)輕(qing)裝入(ru)泵軸上，用手(shou)輕(qing)推(tui)密封環應(ying)能伸縮(suo)自(zi)如，注(zhu)意動、靜(jing)環部分的防轉部位(wei)需裝配到位(wei)。

　　裝(zhuang)聯(lian)軸(zhou)(zhou)器：在電機軸(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈(quan)，裝(zhuang)上(shang)一半(ban)聯(lian)軸(zhou)(zhou)器，再(zai)在泵軸(zhou)(zhou)端(duan)和(he)聯(lian)軸(zhou)(zhou)器槽內裝(zhuang)上(shang)擋塊(kuai)并(bing)用(yong)梅(mei)花扳(ban)手擰緊螺栓；再(zai)裝(zhuang)上(shang)另一半(ban)聯(lian)軸(zhou)(zhou)器擰上(shang)內六角螺釘。安裝(zhuang)聯(lian)軸(zhou)(zhou)器正(zheng)確的檢查要求(qiu)：對分式聯(lian)軸(zhou)(zhou)器上(shang)下間隙(xi)需(xu)要均勻(yun)，用(yong)手盤動(dong)聯(lian)軸(zhou)(zhou)器幾圈(quan)檢查轉動(dong)的靈活性。

　　裝(zhuang)密(mi)(mi)封(feng)座(zuo)：先(xian)將密(mi)(mi)封(feng)座(zuo)裝(zhuang)入橡膠油封(feng)，再把(ba)密(mi)(mi)封(feng)座(zuo)裝(zhuang)入泵蓋(gai)(gai)并壓(ya)(ya)(ya)在(zai)軸承(cheng)座(zuo)上(shang)，擰緊(jin)(jin)螺母，確保所(suo)有安裝(zhuang)螺釘(ding)緊(jin)(jin)固。當安裝(zhuang)螺釘(ding)被(bei)用(yong)作(zuo)密(mi)(mi)封(feng)與(yu)軸之間的驅(qu)動時(shi)，軸應(ying)打埋頭孔來加固連接，緊(jin)(jin)固壓(ya)(ya)(ya)蓋(gai)(gai)螺栓(shuan)時(shi)應(ying)該平穩緊(jin)(jin)固，并且不要(yao)使壓(ya)(ya)(ya)蓋(gai)(gai)受彈力(li)。在(zai)可能的地方使用(yong)4個(ge)以上(shang)螺釘(ding)的等間距壓(ya)(ya)(ya)蓋(gai)(gai)，緊(jin)(jin)固壓(ya)(ya)(ya)蓋(gai)(gai)螺栓(shuan)時(shi)，用(yong)塞尺檢查(cha)軸與(yu)壓(ya)(ya)(ya)蓋(gai)(gai)之間的間隙，這(zhe)在(zai)密(mi)(mi)封(feng)腔對壓(ya)(ya)(ya)蓋(gai)(gai)不導向時(shi)，顯得特別(bie)重(zhong)要(yao)，因為壓(ya)(ya)(ya)蓋(gai)(gai)必(bi)須對中。
