　　傳動形式多，但是洞頭機械密封的(de)更換工(gong)作(zuo)大(da)同小異，首先拆前需確(que)認(ren)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(zuo)腔(qiang)內的(de)潤滑油吸(xi)出。準備(bei)好(hao)放(fang)置泵零件(jian)的(de)工(gong)作(zuo)臺及拆裝工(gong)具，切勿任意(yi)亂放(fang)亂用(yong)，避免碰壞(huai)泵的(de)零部件(jian)。

　　拆對分式聯(lian)軸(zhou)器：先把(ba)聯(lian)軸(zhou)器的固定內六角螺釘擰(ning)(ning)下(xia)來(lai)，再(zai)輕輕把(ba)聯(lian)軸(zhou)器的一半從軸(zhou)上慢(man)慢(man)拉下(xia)，注意不要掉了(le)，再(zai)用梅花扳手擰(ning)(ning)下(xia)泵(beng)軸(zhou)吊緊螺栓和擋(dang)塊(kuai)，讓葉輪(lun)慢(man)慢(man)下(xia)沉至(zhi)泵(beng)體，然后(hou)拆下(xia)另外(wai)一半聯(lian)軸(zhou)器，拿(na)下(xia)泵(beng)軸(zhou)擋(dang)圈。

　　拆卸洞頭機械密封：抓住密封彈簧(huang)順著泵軸往上提，就能拆下(xia)來(lai)了(le)。

　　拆卸(xie)(xie)并(bing)清洗(xi)軸承座(zuo)：先輕(qing)輕(qing)松動一(yi)下軸承座(zuo)后(hou)用拆卸(xie)(xie)螺栓頂起(qi)軸承座(zuo)，并(bing)且沿著(zhu)泵軸往上提而卸(xie)(xie)下，再用噴氣燃料清洗(xi)軸承及座(zuo)，裝前晾(liang)干并(bing)涂抹少(shao)許20號機械油用來潤滑(hua)保護。

　　拆密(mi)封座：擰下密(mi)封座壓緊螺(luo)母(mu)，輕輕卸下密(mi)封座并(bing)清洗。

　　洞頭機械密封裝(zhuang)配：在(zai)動(dong)、靜環(huan)(huan)鏡面上(shang)涂一層(ceng)潔凈的20號潤(run)滑油，導軸(zhou)(zhou)(zhou)承座也抹上(shang)潤(run)滑油，先把(ba)靜環(huan)(huan)輕(qing)輕(qing)定位裝(zhuang)入導軸(zhou)(zhou)(zhou)承座，再在(zai)泵軸(zhou)(zhou)(zhou)上(shang)抹上(shang)潤(run)滑油，把(ba)動(dong)環(huan)(huan)部(bu)分(fen)(fen)輕(qing)輕(qing)裝(zhuang)入泵軸(zhou)(zhou)(zhou)上(shang)，用手輕(qing)推密(mi)封環(huan)(huan)應能伸縮自如，注(zhu)意動(dong)、靜環(huan)(huan)部(bu)分(fen)(fen)的防轉部(bu)位需裝(zhuang)配到位。

　　裝(zhuang)聯(lian)軸(zhou)(zhou)器：在電機軸(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(yi)半聯(lian)軸(zhou)(zhou)器，再(zai)在泵軸(zhou)(zhou)端(duan)和聯(lian)軸(zhou)(zhou)器槽內裝(zhuang)上(shang)(shang)(shang)(shang)擋塊并用梅花扳手擰(ning)緊螺栓；再(zai)裝(zhuang)上(shang)(shang)(shang)(shang)另(ling)一(yi)半聯(lian)軸(zhou)(zhou)器擰(ning)上(shang)(shang)(shang)(shang)內六角螺釘。安裝(zhuang)聯(lian)軸(zhou)(zhou)器正確的(de)檢(jian)查要求：對分(fen)式聯(lian)軸(zhou)(zhou)器上(shang)(shang)(shang)(shang)下間隙需要均勻，用手盤動聯(lian)軸(zhou)(zhou)器幾圈(quan)檢(jian)查轉(zhuan)動的(de)靈活性。

　　裝(zhuang)密封(feng)(feng)座：先將密封(feng)(feng)座裝(zhuang)入(ru)橡膠油封(feng)(feng)，再把密封(feng)(feng)座裝(zhuang)入(ru)泵蓋(gai)(gai)并壓(ya)在(zai)軸承座上(shang)，擰緊(jin)(jin)(jin)螺(luo)母(mu)，確保所有安裝(zhuang)螺(luo)釘緊(jin)(jin)(jin)固。當安裝(zhuang)螺(luo)釘被用作密封(feng)(feng)與軸之間的(de)驅動(dong)時，軸應打(da)埋頭孔來(lai)加(jia)固連接，緊(jin)(jin)(jin)固壓(ya)蓋(gai)(gai)螺(luo)栓時應該(gai)平穩緊(jin)(jin)(jin)固，并且不要使壓(ya)蓋(gai)(gai)受(shou)彈力(li)。在(zai)可能的(de)地方使用4個以(yi)上(shang)螺(luo)釘的(de)等(deng)間距壓(ya)蓋(gai)(gai)，緊(jin)(jin)(jin)固壓(ya)蓋(gai)(gai)螺(luo)栓時，用塞(sai)尺檢查軸與壓(ya)蓋(gai)(gai)之間的(de)間隙，這在(zai)密封(feng)(feng)腔(qiang)對壓(ya)蓋(gai)(gai)不導向(xiang)時，顯(xian)得特別重要，因為壓(ya)蓋(gai)(gai)必須對中(zhong)。
