江漢機械密封利用機械(xie)(xie)(xie)方(fang)式傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，機械(xie)(xie)(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機械(xie)(xie)(xie)工程中應用非常廣泛，有(you)多種形式，主要(yao)包括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪齒(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等(deng)(deng)。齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)能(neng)(neng)夠用于(yu)大功率(lv)的場合，傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)準確(que)，但一般要(yao)求較(jiao)高的制造精度和安裝精度。還有(you)一類是(shi)靠(kao)機件(jian)間的摩(mo)(mo)擦(ca)(ca)(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的摩(mo)(mo)擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和摩(mo)(mo)擦(ca)(ca)(ca)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等(deng)(deng)。摩(mo)(mo)擦(ca)(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易實現無級(ji)變(bian)速，可(ke)以適應軸間距較(jiao)大的傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)場合，而過載打滑(hua)還能(neng)(neng)起到緩沖和保護傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝置的作(zuo)用，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)一般不能(neng)(neng)用于(yu)大功率(lv)的場合，也(ye)不能(neng)(neng)保證準確(que)的傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是江漢機械密封的更換工(gong)作(zuo)大同小異(yi)，首先拆(chai)前需(xu)確認電機處于(yu)檢修(xiu)狀(zhuang)態，擰下(xia)加油(you)螺塞，用吸管把密封(feng)座腔內的潤滑油(you)吸出。準備好放置泵(beng)零(ling)件的工(gong)作(zuo)臺(tai)及拆(chai)裝工(gong)具，切勿(wu)任意亂放亂用，避免碰壞泵(beng)的零(ling)部件。

　　拆對分(fen)式聯(lian)軸器(qi)：先把聯(lian)軸器(qi)的固定內六角螺(luo)釘擰下(xia)來，再(zai)輕輕把聯(lian)軸器(qi)的一(yi)半從軸上慢慢拉下(xia)，注意不要(yao)掉了，再(zai)用梅花(hua)扳手擰下(xia)泵(beng)軸吊緊螺(luo)栓和(he)擋塊，讓(rang)葉輪(lun)慢慢下(xia)沉至泵(beng)體(ti)，然后拆下(xia)另外一(yi)半聯(lian)軸器(qi)，拿下(xia)泵(beng)軸擋圈。

　　拆卸江漢機械密封：抓住(zhu)密封(feng)彈簧(huang)順著(zhu)泵軸往上(shang)提，就能拆(chai)下來(lai)了。

　　拆卸(xie)(xie)并(bing)清(qing)洗(xi)軸承(cheng)座(zuo)：先輕輕松動(dong)一(yi)下軸承(cheng)座(zuo)后(hou)用拆卸(xie)(xie)螺栓頂起(qi)軸承(cheng)座(zuo)，并(bing)且沿著(zhu)泵軸往上提(ti)而卸(xie)(xie)下，再用噴氣燃料清(qing)洗(xi)軸承(cheng)及座(zuo)，裝前晾干并(bing)涂抹少許20號機械油用來潤滑保護。

　　拆密封(feng)(feng)座：擰下密封(feng)(feng)座壓(ya)緊(jin)螺(luo)母(mu)，輕輕卸下密封(feng)(feng)座并清洗。

　　江漢機械密封裝配(pei)：在動、靜(jing)環(huan)鏡(jing)面上(shang)(shang)涂一層潔凈的20號潤滑(hua)(hua)油(you)，導軸(zhou)承座也抹(mo)上(shang)(shang)潤滑(hua)(hua)油(you)，先把靜(jing)環(huan)輕(qing)輕(qing)定(ding)位(wei)裝入(ru)導軸(zhou)承座，再在泵(beng)軸(zhou)上(shang)(shang)抹(mo)上(shang)(shang)潤滑(hua)(hua)油(you)，把動環(huan)部(bu)(bu)分輕(qing)輕(qing)裝入(ru)泵(beng)軸(zhou)上(shang)(shang)，用手輕(qing)推(tui)密封環(huan)應(ying)能伸縮自如，注意(yi)動、靜(jing)環(huan)部(bu)(bu)分的防轉部(bu)(bu)位(wei)需(xu)裝配(pei)到位(wei)。

　　裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)(qi)：在電(dian)機軸(zhou)頭(tou)上裝(zhuang)上擋圈(quan)，裝(zhuang)上一(yi)半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)，再在泵軸(zhou)端和聯(lian)(lian)軸(zhou)器(qi)(qi)槽(cao)內裝(zhuang)上擋塊并用(yong)梅花扳手(shou)擰(ning)緊螺(luo)栓；再裝(zhuang)上另一(yi)半(ban)聯(lian)(lian)軸(zhou)器(qi)(qi)擰(ning)上內六(liu)角螺(luo)釘。安(an)裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)(qi)正確的檢查(cha)要求：對分式聯(lian)(lian)軸(zhou)器(qi)(qi)上下間(jian)隙需要均勻，用(yong)手(shou)盤動聯(lian)(lian)軸(zhou)器(qi)(qi)幾圈(quan)檢查(cha)轉動的靈活性。

　　裝(zhuang)密(mi)(mi)封(feng)座：先(xian)將密(mi)(mi)封(feng)座裝(zhuang)入(ru)(ru)橡膠油(you)封(feng)，再把密(mi)(mi)封(feng)座裝(zhuang)入(ru)(ru)泵蓋(gai)并壓(ya)在(zai)軸承座上(shang)，擰緊(jin)(jin)螺母，確保所(suo)有安裝(zhuang)螺釘(ding)緊(jin)(jin)固(gu)(gu)。當安裝(zhuang)螺釘(ding)被用(yong)作(zuo)密(mi)(mi)封(feng)與軸之(zhi)間的(de)驅動時，軸應打埋(mai)頭(tou)孔來加固(gu)(gu)連接，緊(jin)(jin)固(gu)(gu)壓(ya)蓋(gai)螺栓時應該平穩緊(jin)(jin)固(gu)(gu)，并且不要使壓(ya)蓋(gai)受(shou)彈力。在(zai)可能的(de)地方使用(yong)4個以(yi)上(shang)螺釘(ding)的(de)等間距壓(ya)蓋(gai)，緊(jin)(jin)固(gu)(gu)壓(ya)蓋(gai)螺栓時，用(yong)塞尺(chi)檢(jian)查軸與壓(ya)蓋(gai)之(zhi)間的(de)間隙，這在(zai)密(mi)(mi)封(feng)腔對壓(ya)蓋(gai)不導向時，顯得特別重要，因為壓(ya)蓋(gai)必須對中。
