　　傳動形式多，但是河曲機械密封的更換工(gong)作大同小異，首先拆前需確(que)認電(dian)機(ji)處于檢(jian)修(xiu)狀態，擰下加油螺塞，用(yong)吸管(guan)把密封座(zuo)腔內的潤滑油吸出。準備好放置泵(beng)零(ling)(ling)件的工(gong)作臺及拆裝(zhuang)工(gong)具，切勿任意亂放亂用(yong)，避免碰壞泵(beng)的零(ling)(ling)部件。

　　拆對分式聯(lian)軸(zhou)器(qi)(qi)：先把(ba)聯(lian)軸(zhou)器(qi)(qi)的固定內六角螺釘(ding)擰下來，再(zai)輕輕把(ba)聯(lian)軸(zhou)器(qi)(qi)的一(yi)半從軸(zhou)上慢(man)慢(man)拉(la)下，注意不要(yao)掉了，再(zai)用梅花(hua)扳手(shou)擰下泵軸(zhou)吊緊螺栓(shuan)和擋塊，讓(rang)葉輪慢(man)慢(man)下沉(chen)至泵體(ti)，然后(hou)拆下另外(wai)一(yi)半聯(lian)軸(zhou)器(qi)(qi)，拿下泵軸(zhou)擋圈(quan)。

　　拆卸河曲機械密封：抓(zhua)住密封彈簧順著泵軸(zhou)往上提，就能拆下(xia)來了。

　　拆(chai)卸(xie)并清洗(xi)軸(zhou)承座(zuo)：先輕(qing)輕(qing)松(song)動一下(xia)軸(zhou)承座(zuo)后用拆(chai)卸(xie)螺栓(shuan)頂起軸(zhou)承座(zuo)，并且沿著泵軸(zhou)往(wang)上提而卸(xie)下(xia)，再用噴氣燃料清洗(xi)軸(zhou)承及座(zuo)，裝(zhuang)前(qian)晾干并涂抹少許(xu)20號機械(xie)油用來(lai)潤滑保護。

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

　　河曲機械密封裝配：在(zai)動、靜環(huan)鏡面上(shang)涂一層潔(jie)凈的(de)20號潤(run)(run)滑(hua)(hua)油(you)，導軸承(cheng)座(zuo)也抹(mo)上(shang)潤(run)(run)滑(hua)(hua)油(you)，先把(ba)靜環(huan)輕(qing)(qing)輕(qing)(qing)定位裝入導軸承(cheng)座(zuo)，再(zai)在(zai)泵軸上(shang)抹(mo)上(shang)潤(run)(run)滑(hua)(hua)油(you)，把(ba)動環(huan)部分輕(qing)(qing)輕(qing)(qing)裝入泵軸上(shang)，用手輕(qing)(qing)推(tui)密封(feng)環(huan)應能伸縮自如，注意動、靜環(huan)部分的(de)防轉部位需裝配到位。

　　裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)擋(dang)圈(quan)，裝(zhuang)(zhuang)上(shang)(shang)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)，再在泵軸(zhou)(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)槽內(nei)裝(zhuang)(zhuang)上(shang)(shang)擋(dang)塊并用梅花扳手擰緊螺栓；再裝(zhuang)(zhuang)上(shang)(shang)另一半聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)擰上(shang)(shang)內(nei)六角螺釘。安(an)裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)正(zheng)確的(de)檢(jian)查要(yao)求：對(dui)分式聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)上(shang)(shang)下間(jian)隙需要(yao)均勻，用手盤動(dong)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)幾圈(quan)檢(jian)查轉動(dong)的(de)靈活(huo)性。

　　裝(zhuang)密(mi)封(feng)(feng)座(zuo)(zuo)：先將(jiang)密(mi)封(feng)(feng)座(zuo)(zuo)裝(zhuang)入(ru)橡膠油封(feng)(feng)，再把(ba)密(mi)封(feng)(feng)座(zuo)(zuo)裝(zhuang)入(ru)泵蓋(gai)并壓(ya)在軸(zhou)承座(zuo)(zuo)上，擰(ning)緊螺母，確(que)保所有安裝(zhuang)螺釘(ding)緊固。當安裝(zhuang)螺釘(ding)被用作密(mi)封(feng)(feng)與軸(zhou)之間的驅動時，軸(zhou)應(ying)打埋頭孔來加固連(lian)接，緊固壓(ya)蓋(gai)螺栓時應(ying)該(gai)平穩緊固，并且不(bu)要使(shi)壓(ya)蓋(gai)受彈(dan)力。在可能的地方使(shi)用4個以(yi)上螺釘(ding)的等間距壓(ya)蓋(gai)，緊固壓(ya)蓋(gai)螺栓時，用塞尺檢查軸(zhou)與壓(ya)蓋(gai)之間的間隙，這在密(mi)封(feng)(feng)腔對(dui)壓(ya)蓋(gai)不(bu)導向時，顯得(de)特(te)別重要，因為壓(ya)蓋(gai)必須(xu)對(dui)中。
