鄱陽機械密封利用(yong)機(ji)(ji)械(xie)(xie)方(fang)式傳(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)(li)(li)和(he)運動(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械(xie)(xie)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械(xie)(xie)工(gong)程(cheng)中應用(yong)非常廣(guang)泛，有多種(zhong)形式，主要(yao)包括皮帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)(gua)桿蝸(gua)(gua)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。齒輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能夠用(yong)于(yu)大(da)功率的場(chang)合(he)(he)，傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)準確，但一(yi)般(ban)要(yao)求較(jiao)高的制(zhi)造精度(du)和(he)安裝精度(du)。還有一(yi)類是靠(kao)機(ji)(ji)件間的摩擦(ca)(ca)(ca)力(li)(li)(li)傳(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)(li)(li)和(he)運動(dong)(dong)(dong)(dong)(dong)的摩擦(ca)(ca)(ca)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)摩擦(ca)(ca)(ca)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。摩擦(ca)(ca)(ca)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實現(xian)無級(ji)變速(su)，可以適應軸(zhou)間距較(jiao)大(da)的傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合(he)(he)，而(er)過載打滑還能起到緩沖和(he)保護傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的作(zuo)用(yong)，但這種(zhong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)不能用(yong)于(yu)大(da)功率的場(chang)合(he)(he)，也不能保證準確的傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)(bi)。

　　傳動形式多，但是鄱陽機械密封的(de)更換工(gong)作(zuo)大同小異，首(shou)先拆前需(xu)確(que)認電機處于檢修狀(zhuang)態，擰下(xia)加油螺塞，用吸管把密封座腔(qiang)內的(de)潤滑油吸出。準備好(hao)放置(zhi)泵零(ling)件(jian)的(de)工(gong)作(zuo)臺(tai)及拆裝(zhuang)工(gong)具(ju)，切勿任意亂(luan)放亂(luan)用，避免碰壞泵的(de)零(ling)部(bu)件(jian)。

　　拆(chai)對分式聯軸器：先把(ba)聯軸器的固(gu)定內(nei)六角螺釘擰下來，再輕輕把(ba)聯軸器的一半(ban)從軸上(shang)慢(man)慢(man)拉下，注意不要掉了，再用(yong)梅花扳手擰下泵軸吊(diao)緊螺栓和(he)擋塊，讓葉(xie)輪(lun)慢(man)慢(man)下沉至泵體，然后拆(chai)下另(ling)外(wai)一半(ban)聯軸器，拿(na)下泵軸擋圈(quan)。

　　拆卸鄱陽機械密封：抓住密封彈(dan)簧(huang)順著泵軸往上提，就能拆(chai)下來(lai)了。

　　拆卸并清(qing)洗(xi)軸(zhou)承(cheng)(cheng)座：先輕輕松動一下(xia)軸(zhou)承(cheng)(cheng)座后用(yong)拆卸螺栓頂起軸(zhou)承(cheng)(cheng)座，并且沿著泵軸(zhou)往上提而卸下(xia)，再用(yong)噴(pen)氣燃料清(qing)洗(xi)軸(zhou)承(cheng)(cheng)及座，裝前晾(liang)干并涂抹少許20號機械油用(yong)來(lai)潤滑保護。

　　拆密(mi)(mi)封(feng)座：擰下密(mi)(mi)封(feng)座壓(ya)緊螺母，輕(qing)輕(qing)卸下密(mi)(mi)封(feng)座并清(qing)洗。

　　鄱陽機械密封裝配(pei)：在(zai)動、靜環(huan)鏡面上(shang)(shang)涂一層潔(jie)凈的(de)20號潤滑油(you)，導軸承座也(ye)抹(mo)上(shang)(shang)潤滑油(you)，先把靜環(huan)輕輕定位(wei)裝入(ru)(ru)導軸承座，再在(zai)泵軸上(shang)(shang)抹(mo)上(shang)(shang)潤滑油(you)，把動環(huan)部分輕輕裝入(ru)(ru)泵軸上(shang)(shang)，用手輕推密(mi)封環(huan)應能(neng)伸縮自如，注意動、靜環(huan)部分的(de)防轉部位(wei)需(xu)裝配(pei)到位(wei)。

　　裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器：在電機(ji)軸(zhou)(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈(quan)，裝(zhuang)上(shang)一半(ban)(ban)聯(lian)(lian)軸(zhou)(zhou)(zhou)器，再在泵軸(zhou)(zhou)(zhou)端和(he)聯(lian)(lian)軸(zhou)(zhou)(zhou)器槽內裝(zhuang)上(shang)擋塊并用(yong)梅花扳手(shou)擰(ning)緊螺栓；再裝(zhuang)上(shang)另一半(ban)(ban)聯(lian)(lian)軸(zhou)(zhou)(zhou)器擰(ning)上(shang)內六角螺釘(ding)。安(an)裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器正確的檢(jian)查要(yao)求：對分(fen)式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器上(shang)下(xia)間隙需(xu)要(yao)均勻，用(yong)手(shou)盤動聯(lian)(lian)軸(zhou)(zhou)(zhou)器幾圈(quan)檢(jian)查轉動的靈活性。

　　裝密(mi)封座(zuo)：先將密(mi)封座(zuo)裝入橡膠油封，再(zai)把密(mi)封座(zuo)裝入泵蓋(gai)(gai)(gai)(gai)并壓(ya)(ya)(ya)在(zai)軸承座(zuo)上，擰緊螺(luo)母，確保(bao)所有安裝螺(luo)釘(ding)(ding)緊固(gu)(gu)。當安裝螺(luo)釘(ding)(ding)被用(yong)作密(mi)封與軸之間(jian)的驅動時，軸應打埋頭孔來(lai)加固(gu)(gu)連接(jie)，緊固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)螺(luo)栓(shuan)時應該平穩緊固(gu)(gu)，并且不要(yao)使壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)受彈力。在(zai)可(ke)能的地方使用(yong)4個以上螺(luo)釘(ding)(ding)的等間(jian)距壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)，緊固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)螺(luo)栓(shuan)時，用(yong)塞尺檢查軸與壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)之間(jian)的間(jian)隙，這在(zai)密(mi)封腔對壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)不導向(xiang)時，顯得特(te)別重(zhong)要(yao)，因為壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)必須對中。
