　　傳動形式多，但是前鋒機械密封的(de)更換工作大同小(xiao)異，首(shou)先拆前需(xu)確(que)認電機(ji)處(chu)于檢修狀態，擰下(xia)加(jia)油螺(luo)塞，用(yong)吸(xi)管把密封座(zuo)腔內的(de)潤滑油吸(xi)出。準備好(hao)放置泵(beng)零(ling)件的(de)工作臺及拆裝工具，切勿任意亂(luan)放亂(luan)用(yong)，避免碰壞泵(beng)的(de)零(ling)部(bu)件。

　　拆對分式聯(lian)軸(zhou)器(qi)：先把聯(lian)軸(zhou)器(qi)的固定內六角螺(luo)(luo)釘擰(ning)下(xia)(xia)(xia)來，再輕(qing)(qing)輕(qing)(qing)把聯(lian)軸(zhou)器(qi)的一(yi)半(ban)從軸(zhou)上慢(man)慢(man)拉下(xia)(xia)(xia)，注意不要掉了，再用(yong)梅花(hua)扳手擰(ning)下(xia)(xia)(xia)泵軸(zhou)吊緊螺(luo)(luo)栓和(he)擋塊，讓葉輪(lun)慢(man)慢(man)下(xia)(xia)(xia)沉(chen)至(zhi)泵體，然(ran)后拆下(xia)(xia)(xia)另外一(yi)半(ban)聯(lian)軸(zhou)器(qi)，拿下(xia)(xia)(xia)泵軸(zhou)擋圈。

　　拆卸前鋒機械密封：抓住密封彈簧(huang)順著(zhu)泵軸往(wang)上提，就能拆下來(lai)了(le)。

　　拆(chai)卸(xie)(xie)并清(qing)洗軸(zhou)承座(zuo)：先輕輕松動(dong)一下(xia)軸(zhou)承座(zuo)后用(yong)拆(chai)卸(xie)(xie)螺栓(shuan)頂起軸(zhou)承座(zuo)，并且沿(yan)著泵(beng)軸(zhou)往上提而(er)卸(xie)(xie)下(xia)，再用(yong)噴氣燃料清(qing)洗軸(zhou)承及(ji)座(zuo)，裝前(qian)晾干(gan)并涂抹少許20號機械油用(yong)來(lai)潤滑保護。

　　拆密封座：擰下密封座壓緊螺母，輕輕卸下密封座并清(qing)洗(xi)。

　　前鋒機械密封裝(zhuang)配(pei)：在動(dong)(dong)、靜(jing)環鏡面上(shang)(shang)涂一層潔凈的(de)20號(hao)潤滑油(you)，導軸(zhou)承座也(ye)抹上(shang)(shang)潤滑油(you)，先把(ba)靜(jing)環輕(qing)輕(qing)定位(wei)裝(zhuang)入(ru)導軸(zhou)承座，再(zai)在泵軸(zhou)上(shang)(shang)抹上(shang)(shang)潤滑油(you)，把(ba)動(dong)(dong)環部(bu)分輕(qing)輕(qing)裝(zhuang)入(ru)泵軸(zhou)上(shang)(shang)，用手(shou)輕(qing)推(tui)密封環應能伸(shen)縮自如，注意動(dong)(dong)、靜(jing)環部(bu)分的(de)防轉(zhuan)部(bu)位(wei)需裝(zhuang)配(pei)到(dao)位(wei)。

　　裝聯軸(zhou)器(qi)(qi)：在電機軸(zhou)頭上(shang)裝上(shang)擋(dang)圈(quan)(quan)，裝上(shang)一半聯軸(zhou)器(qi)(qi)，再在泵軸(zhou)端和聯軸(zhou)器(qi)(qi)槽內裝上(shang)擋(dang)塊(kuai)并用(yong)梅花扳手擰緊(jin)螺(luo)栓；再裝上(shang)另一半聯軸(zhou)器(qi)(qi)擰上(shang)內六角螺(luo)釘。安裝聯軸(zhou)器(qi)(qi)正(zheng)確的(de)檢查要求(qiu)：對分式聯軸(zhou)器(qi)(qi)上(shang)下間(jian)隙需要均勻，用(yong)手盤動聯軸(zhou)器(qi)(qi)幾圈(quan)(quan)檢查轉(zhuan)動的(de)靈(ling)活性。

　　裝(zhuang)(zhuang)密(mi)(mi)(mi)封(feng)座(zuo)(zuo)(zuo)：先將密(mi)(mi)(mi)封(feng)座(zuo)(zuo)(zuo)裝(zhuang)(zhuang)入橡膠油封(feng)，再把密(mi)(mi)(mi)封(feng)座(zuo)(zuo)(zuo)裝(zhuang)(zhuang)入泵蓋(gai)并(bing)壓(ya)(ya)(ya)在軸承(cheng)座(zuo)(zuo)(zuo)上，擰緊(jin)(jin)螺母，確保所有安裝(zhuang)(zhuang)螺釘緊(jin)(jin)固(gu)(gu)。當安裝(zhuang)(zhuang)螺釘被用作密(mi)(mi)(mi)封(feng)與軸之(zhi)(zhi)間的驅動時(shi)(shi)，軸應打埋頭孔來(lai)加固(gu)(gu)連接，緊(jin)(jin)固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺栓時(shi)(shi)應該平穩緊(jin)(jin)固(gu)(gu)，并(bing)且不要(yao)使壓(ya)(ya)(ya)蓋(gai)受彈力(li)。在可能(neng)的地方使用4個以上螺釘的等間距壓(ya)(ya)(ya)蓋(gai)，緊(jin)(jin)固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺栓時(shi)(shi)，用塞尺檢查軸與壓(ya)(ya)(ya)蓋(gai)之(zhi)(zhi)間的間隙，這在密(mi)(mi)(mi)封(feng)腔對壓(ya)(ya)(ya)蓋(gai)不導向時(shi)(shi)，顯(xian)得特別重(zhong)要(yao)，因為(wei)壓(ya)(ya)(ya)蓋(gai)必(bi)須對中。
