鄱陽機械密封利用(yong)機械方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機械工程中應用(yong)非常廣泛，有(you)多種形式，主(zhu)要(yao)包括(kuo)皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。齒輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能夠(gou)用(yong)于大(da)功率的(de)場(chang)合(he)，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比準(zhun)(zhun)確，但(dan)(dan)一(yi)(yi)般(ban)要(yao)求較高的(de)制造精度(du)和安裝精度(du)。還有(you)一(yi)(yi)類是靠(kao)機件間的(de)摩(mo)擦力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括(kuo)帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和摩(mo)擦輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實現無級變速，可以適應軸間距較大(da)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合(he)，而過載(zai)打(da)滑(hua)還能起(qi)到緩沖和保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的(de)作用(yong)，但(dan)(dan)這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)(yi)般(ban)不能用(yong)于大(da)功率的(de)場(chang)合(he)，也不能保證準(zhun)(zhun)確的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是鄱陽機械密封的更換工(gong)作大同小異(yi)，首先拆(chai)前需確認電機(ji)處于檢修狀態，擰(ning)下加油(you)螺塞，用(yong)吸(xi)管把(ba)密封座腔內(nei)的潤滑(hua)油(you)吸(xi)出。準備(bei)好(hao)放置(zhi)泵零件(jian)的工(gong)作臺及拆(chai)裝工(gong)具，切勿任(ren)意亂放亂用(yong)，避免(mian)碰壞泵的零部件(jian)。

　　拆對分式聯(lian)軸(zhou)器(qi)(qi)：先把聯(lian)軸(zhou)器(qi)(qi)的固定(ding)內六角螺釘(ding)擰(ning)下(xia)來，再(zai)輕(qing)輕(qing)把聯(lian)軸(zhou)器(qi)(qi)的一(yi)半從軸(zhou)上慢(man)(man)慢(man)(man)拉下(xia)，注(zhu)意不要掉了，再(zai)用梅花扳手擰(ning)下(xia)泵軸(zhou)吊(diao)緊螺栓和(he)擋(dang)塊，讓葉輪慢(man)(man)慢(man)(man)下(xia)沉至泵體(ti)，然后(hou)拆下(xia)另外一(yi)半聯(lian)軸(zhou)器(qi)(qi)，拿下(xia)泵軸(zhou)擋(dang)圈。

　　拆卸鄱陽機械密封：抓住密(mi)封彈簧順著泵軸往上提，就(jiu)能拆下(xia)來了。

　　拆(chai)卸(xie)并清洗軸承座(zuo)：先輕(qing)輕(qing)松動一下軸承座(zuo)后用拆(chai)卸(xie)螺栓頂起軸承座(zuo)，并且沿著泵(beng)軸往上提而卸(xie)下，再用噴氣燃料(liao)清洗軸承及(ji)座(zuo)，裝前晾(liang)干并涂抹少許20號機(ji)械油用來潤滑(hua)保護。

　　拆密(mi)封座(zuo)(zuo)：擰(ning)下密(mi)封座(zuo)(zuo)壓緊螺母，輕(qing)輕(qing)卸下密(mi)封座(zuo)(zuo)并清洗。

　　鄱陽機械密封裝(zhuang)配：在(zai)動(dong)、靜環鏡面上涂一(yi)層潔凈的20號潤滑(hua)油(you)(you)，導軸承座也(ye)抹(mo)上潤滑(hua)油(you)(you)，先把(ba)(ba)靜環輕(qing)(qing)輕(qing)(qing)定位(wei)裝(zhuang)入(ru)導軸承座，再在(zai)泵軸上抹(mo)上潤滑(hua)油(you)(you)，把(ba)(ba)動(dong)環部(bu)分輕(qing)(qing)輕(qing)(qing)裝(zhuang)入(ru)泵軸上，用手(shou)輕(qing)(qing)推密封環應能伸縮自如，注(zhu)意(yi)動(dong)、靜環部(bu)分的防(fang)轉部(bu)位(wei)需裝(zhuang)配到(dao)位(wei)。

　　裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)(zhou)(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈，裝(zhuang)上(shang)一(yi)半聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)，再(zai)在泵軸(zhou)(zhou)(zhou)(zhou)(zhou)端和(he)聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)槽內裝(zhuang)上(shang)擋塊并(bing)用(yong)梅(mei)花扳手擰(ning)緊螺栓；再(zai)裝(zhuang)上(shang)另一(yi)半聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)擰(ning)上(shang)內六角(jiao)螺釘。安裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)正確的檢(jian)查要求：對分式聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)上(shang)下間隙需要均勻(yun)，用(yong)手盤(pan)動聯(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)幾(ji)圈檢(jian)查轉動的靈活(huo)性。

　　裝密(mi)封(feng)座(zuo)：先將密(mi)封(feng)座(zuo)裝入(ru)橡膠油封(feng)，再把密(mi)封(feng)座(zuo)裝入(ru)泵蓋(gai)(gai)并壓(ya)在軸(zhou)承座(zuo)上(shang)，擰緊(jin)螺(luo)母，確保所(suo)有安裝螺(luo)釘緊(jin)固(gu)。當(dang)安裝螺(luo)釘被用作密(mi)封(feng)與軸(zhou)之間的驅動時(shi)(shi)，軸(zhou)應(ying)打埋頭孔來加(jia)固(gu)連接，緊(jin)固(gu)壓(ya)蓋(gai)(gai)螺(luo)栓時(shi)(shi)應(ying)該(gai)平穩緊(jin)固(gu)，并且不(bu)要(yao)使(shi)壓(ya)蓋(gai)(gai)受彈力。在可能的地方使(shi)用4個以(yi)上(shang)螺(luo)釘的等間距(ju)壓(ya)蓋(gai)(gai)，緊(jin)固(gu)壓(ya)蓋(gai)(gai)螺(luo)栓時(shi)(shi)，用塞尺檢查軸(zhou)與壓(ya)蓋(gai)(gai)之間的間隙(xi)，這(zhe)在密(mi)封(feng)腔對壓(ya)蓋(gai)(gai)不(bu)導(dao)向時(shi)(shi)，顯得(de)特別重(zhong)要(yao)，因為壓(ya)蓋(gai)(gai)必須對中。
