　　傳動形式多，但是金鄉機械密封的更換工作大同小異，首先(xian)拆(chai)前需確(que)認電(dian)機處于檢修狀態，擰下加油螺塞，用吸管把密封座腔內的潤(run)滑油吸出。準(zhun)備好放(fang)置泵零(ling)件(jian)的工作臺及拆(chai)裝工具，切勿任意亂放(fang)亂用，避免碰(peng)壞(huai)泵的零(ling)部(bu)件(jian)。

　　拆對(dui)分式聯軸(zhou)(zhou)器：先把(ba)聯軸(zhou)(zhou)器的(de)固(gu)定內六(liu)角螺釘(ding)擰下(xia)(xia)來，再(zai)輕(qing)輕(qing)把(ba)聯軸(zhou)(zhou)器的(de)一(yi)半從(cong)軸(zhou)(zhou)上慢慢拉下(xia)(xia)，注意(yi)不要掉了，再(zai)用梅花扳手擰下(xia)(xia)泵(beng)軸(zhou)(zhou)吊(diao)緊螺栓和擋(dang)塊(kuai)，讓葉輪慢慢下(xia)(xia)沉至泵(beng)體，然(ran)后拆下(xia)(xia)另外一(yi)半聯軸(zhou)(zhou)器，拿下(xia)(xia)泵(beng)軸(zhou)(zhou)擋(dang)圈。

　　拆卸金鄉機械密封：抓(zhua)住(zhu)密封彈簧順著(zhu)泵軸往上提，就(jiu)能(neng)拆下來了。

　　拆(chai)卸并(bing)(bing)清洗(xi)軸(zhou)(zhou)承座：先輕(qing)(qing)輕(qing)(qing)松動一(yi)下軸(zhou)(zhou)承座后用(yong)拆(chai)卸螺栓頂(ding)起軸(zhou)(zhou)承座，并(bing)(bing)且(qie)沿著泵軸(zhou)(zhou)往上(shang)提而(er)卸下，再(zai)用(yong)噴氣燃(ran)料清洗(xi)軸(zhou)(zhou)承及座，裝前晾干并(bing)(bing)涂抹(mo)少許20號機械(xie)油用(yong)來潤滑(hua)保(bao)護。

　　拆密(mi)封(feng)座(zuo)：擰下密(mi)封(feng)座(zuo)壓緊(jin)螺母，輕輕卸下密(mi)封(feng)座(zuo)并(bing)清(qing)洗。

　　金鄉機械密封裝(zhuang)配：在(zai)動(dong)、靜(jing)環(huan)(huan)鏡面(mian)上(shang)涂一層潔凈(jing)的(de)20號潤滑(hua)油，導(dao)軸承座(zuo)也抹上(shang)潤滑(hua)油，先把(ba)靜(jing)環(huan)(huan)輕輕定位裝(zhuang)入導(dao)軸承座(zuo)，再在(zai)泵軸上(shang)抹上(shang)潤滑(hua)油，把(ba)動(dong)環(huan)(huan)部分輕輕裝(zhuang)入泵軸上(shang)，用手輕推密封環(huan)(huan)應能伸縮(suo)自如，注意動(dong)、靜(jing)環(huan)(huan)部分的(de)防轉(zhuan)部位需裝(zhuang)配到位。

　　裝聯(lian)軸(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)頭上(shang)裝上(shang)擋圈(quan)，裝上(shang)一(yi)(yi)半(ban)聯(lian)軸(zhou)(zhou)器(qi)，再(zai)在泵軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)槽內(nei)裝上(shang)擋塊(kuai)并用(yong)梅(mei)花扳(ban)手擰緊螺(luo)栓；再(zai)裝上(shang)另(ling)一(yi)(yi)半(ban)聯(lian)軸(zhou)(zhou)器(qi)擰上(shang)內(nei)六角螺(luo)釘。安裝聯(lian)軸(zhou)(zhou)器(qi)正確的(de)檢(jian)查(cha)要求：對分式聯(lian)軸(zhou)(zhou)器(qi)上(shang)下間(jian)隙需要均勻，用(yong)手盤動聯(lian)軸(zhou)(zhou)器(qi)幾(ji)圈(quan)檢(jian)查(cha)轉動的(de)靈活性。

　　裝(zhuang)密(mi)(mi)封(feng)座(zuo)(zuo)：先將密(mi)(mi)封(feng)座(zuo)(zuo)裝(zhuang)入橡膠油封(feng)，再(zai)把密(mi)(mi)封(feng)座(zuo)(zuo)裝(zhuang)入泵蓋(gai)并(bing)(bing)壓(ya)(ya)在(zai)軸承座(zuo)(zuo)上，擰(ning)緊螺(luo)(luo)母，確保所有安裝(zhuang)螺(luo)(luo)釘(ding)緊固。當安裝(zhuang)螺(luo)(luo)釘(ding)被(bei)用作密(mi)(mi)封(feng)與(yu)軸之(zhi)間的驅動時，軸應(ying)打埋(mai)頭(tou)孔來加固連接，緊固壓(ya)(ya)蓋(gai)螺(luo)(luo)栓時應(ying)該平穩緊固，并(bing)(bing)且不要使壓(ya)(ya)蓋(gai)受(shou)彈力(li)。在(zai)可能的地方使用4個以上螺(luo)(luo)釘(ding)的等間距壓(ya)(ya)蓋(gai)，緊固壓(ya)(ya)蓋(gai)螺(luo)(luo)栓時，用塞尺檢(jian)查軸與(yu)壓(ya)(ya)蓋(gai)之(zhi)間的間隙，這在(zai)密(mi)(mi)封(feng)腔對(dui)壓(ya)(ya)蓋(gai)不導向時，顯得(de)特別(bie)重要，因為壓(ya)(ya)蓋(gai)必須對(dui)中(zhong)。
