　　傳動形式多，但是梅江機械密封的更換工(gong)作大同小異，首(shou)先拆前需確(que)認(ren)電機(ji)處(chu)于檢修狀態，擰下加(jia)油螺塞，用吸(xi)管把密封座腔內的潤滑油吸(xi)出。準備好放置泵零(ling)件(jian)的工(gong)作臺(tai)及拆裝工(gong)具，切勿任意亂(luan)放亂(luan)用，避(bi)免碰(peng)壞(huai)泵的零(ling)部件(jian)。

　　拆對分(fen)式聯(lian)軸(zhou)器(qi)：先把聯(lian)軸(zhou)器(qi)的固定內六角螺(luo)釘(ding)擰下來(lai)，再(zai)輕(qing)輕(qing)把聯(lian)軸(zhou)器(qi)的一半從軸(zhou)上慢(man)(man)慢(man)(man)拉下，注意不要掉了，再(zai)用梅花(hua)扳手擰下泵(beng)軸(zhou)吊緊螺(luo)栓(shuan)和擋(dang)塊，讓(rang)葉輪慢(man)(man)慢(man)(man)下沉(chen)至泵(beng)體，然后拆下另外一半聯(lian)軸(zhou)器(qi)，拿下泵(beng)軸(zhou)擋(dang)圈。

　　拆卸梅江機械密封：抓(zhua)住密封彈(dan)簧(huang)順(shun)著泵(beng)軸往(wang)上提，就能拆(chai)下(xia)來了。

　　拆卸并清洗軸(zhou)(zhou)承座：先輕(qing)輕(qing)松動一(yi)下(xia)(xia)軸(zhou)(zhou)承座后用(yong)拆卸螺栓頂起軸(zhou)(zhou)承座，并且沿著泵軸(zhou)(zhou)往上提而卸下(xia)(xia)，再(zai)用(yong)噴氣燃料(liao)清洗軸(zhou)(zhou)承及座，裝前晾干并涂(tu)抹(mo)少許20號機械油用(yong)來潤滑保護。

　　拆密(mi)封座：擰下(xia)密(mi)封座壓緊螺母(mu)，輕(qing)輕(qing)卸下(xia)密(mi)封座并清洗。

　　梅江機械密封裝(zhuang)配(pei)：在(zai)動(dong)、靜環(huan)(huan)(huan)鏡面(mian)上(shang)涂一層潔(jie)凈(jing)的(de)20號潤(run)滑(hua)油(you)，導軸(zhou)承座(zuo)也抹上(shang)潤(run)滑(hua)油(you)，先(xian)把(ba)靜環(huan)(huan)(huan)輕(qing)輕(qing)定(ding)位(wei)裝(zhuang)入導軸(zhou)承座(zuo)，再(zai)在(zai)泵軸(zhou)上(shang)抹上(shang)潤(run)滑(hua)油(you)，把(ba)動(dong)環(huan)(huan)(huan)部分輕(qing)輕(qing)裝(zhuang)入泵軸(zhou)上(shang)，用手輕(qing)推密封環(huan)(huan)(huan)應能伸縮自(zi)如(ru)，注(zhu)意動(dong)、靜環(huan)(huan)(huan)部分的(de)防轉部位(wei)需裝(zhuang)配(pei)到位(wei)。

　　裝(zhuang)聯(lian)(lian)軸(zhou)器：在電機軸(zhou)頭上裝(zhuang)上擋圈，裝(zhuang)上一半聯(lian)(lian)軸(zhou)器，再在泵(beng)軸(zhou)端和(he)聯(lian)(lian)軸(zhou)器槽(cao)內(nei)裝(zhuang)上擋塊并用梅花扳手(shou)擰(ning)緊螺栓；再裝(zhuang)上另(ling)一半聯(lian)(lian)軸(zhou)器擰(ning)上內(nei)六角(jiao)螺釘。安裝(zhuang)聯(lian)(lian)軸(zhou)器正(zheng)確的檢查要求：對(dui)分(fen)式(shi)聯(lian)(lian)軸(zhou)器上下間(jian)隙需要均勻(yun)，用手(shou)盤動聯(lian)(lian)軸(zhou)器幾圈檢查轉動的靈(ling)活性。

　　裝(zhuang)密封(feng)座：先將密封(feng)座裝(zhuang)入(ru)橡膠(jiao)油封(feng)，再把密封(feng)座裝(zhuang)入(ru)泵蓋(gai)(gai)并(bing)(bing)壓(ya)(ya)在軸承座上，擰緊(jin)螺(luo)母，確保所有安(an)裝(zhuang)螺(luo)釘緊(jin)固(gu)。當(dang)安(an)裝(zhuang)螺(luo)釘被用(yong)作(zuo)密封(feng)與軸之(zhi)間(jian)的(de)(de)(de)驅動時，軸應(ying)(ying)打埋頭孔來加固(gu)連接，緊(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓時應(ying)(ying)該(gai)平穩緊(jin)固(gu)，并(bing)(bing)且(qie)不要(yao)(yao)使壓(ya)(ya)蓋(gai)(gai)受彈力。在可(ke)能(neng)的(de)(de)(de)地方(fang)使用(yong)4個(ge)以上螺(luo)釘的(de)(de)(de)等間(jian)距壓(ya)(ya)蓋(gai)(gai)，緊(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓時，用(yong)塞尺(chi)檢(jian)查(cha)軸與壓(ya)(ya)蓋(gai)(gai)之(zhi)間(jian)的(de)(de)(de)間(jian)隙，這(zhe)在密封(feng)腔對壓(ya)(ya)蓋(gai)(gai)不導(dao)向(xiang)時，顯(xian)得特別(bie)重要(yao)(yao)，因為壓(ya)(ya)蓋(gai)(gai)必須對中。
