上饒機械密封利(li)用機(ji)械方式傳(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)械工程(cheng)中應(ying)用非常(chang)廣泛，有(you)多種形式，主要(yao)包括皮帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和螺旋(xuan)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能夠用于大(da)(da)(da)功率的(de)(de)場合，傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)準(zhun)確(que)，但一般要(yao)求(qiu)較(jiao)高的(de)(de)制造精度(du)和安裝精度(du)。還(huan)有(you)一類(lei)是靠(kao)機(ji)件間的(de)(de)摩(mo)擦(ca)(ca)力傳(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)摩(mo)擦(ca)(ca)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和摩(mo)擦(ca)(ca)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)(ca)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速，可以適應(ying)軸(zhou)間距較(jiao)大(da)(da)(da)的(de)(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場合，而過載打滑還(huan)能起到緩沖和保(bao)護傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)作用，但這種傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一般不能用于大(da)(da)(da)功率的(de)(de)場合，也不能保(bao)證準(zhun)確(que)的(de)(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是上饒機械密封的更換工(gong)作大同小異，首(shou)先拆(chai)前需確認電機處于檢修狀態(tai)，擰下(xia)加(jia)油螺(luo)塞(sai)，用吸(xi)管把密封座腔內的潤(run)滑油吸(xi)出。準備好放置泵零件的工(gong)作臺及拆(chai)裝工(gong)具，切(qie)勿任意(yi)亂放亂用，避免碰壞(huai)泵的零部件。

　　拆(chai)對分式聯(lian)軸(zhou)(zhou)器(qi)：先把聯(lian)軸(zhou)(zhou)器(qi)的固定內六(liu)角(jiao)螺釘擰(ning)下(xia)(xia)(xia)來，再(zai)輕(qing)(qing)輕(qing)(qing)把聯(lian)軸(zhou)(zhou)器(qi)的一(yi)半(ban)從(cong)軸(zhou)(zhou)上(shang)慢(man)慢(man)拉下(xia)(xia)(xia)，注意不要掉(diao)了，再(zai)用梅花扳手擰(ning)下(xia)(xia)(xia)泵軸(zhou)(zhou)吊(diao)緊螺栓(shuan)和擋塊，讓葉輪慢(man)慢(man)下(xia)(xia)(xia)沉至(zhi)泵體，然后(hou)拆(chai)下(xia)(xia)(xia)另外一(yi)半(ban)聯(lian)軸(zhou)(zhou)器(qi)，拿下(xia)(xia)(xia)泵軸(zhou)(zhou)擋圈。

　　拆卸上饒機械密封：抓住密封(feng)彈簧順著泵軸往上提(ti)，就能拆(chai)下來(lai)了(le)。

　　拆卸(xie)(xie)并清(qing)洗軸(zhou)(zhou)承(cheng)座：先輕(qing)(qing)輕(qing)(qing)松動一下(xia)軸(zhou)(zhou)承(cheng)座后用(yong)拆卸(xie)(xie)螺栓(shuan)頂起(qi)軸(zhou)(zhou)承(cheng)座，并且沿著泵軸(zhou)(zhou)往上(shang)提而卸(xie)(xie)下(xia)，再用(yong)噴氣(qi)燃料清(qing)洗軸(zhou)(zhou)承(cheng)及(ji)座，裝前晾干并涂抹少許20號(hao)機械(xie)油用(yong)來潤滑保(bao)護。

　　拆密(mi)封(feng)座(zuo)：擰下(xia)密(mi)封(feng)座(zuo)壓緊螺母，輕輕卸下(xia)密(mi)封(feng)座(zuo)并清洗。

　　上饒機械密封裝(zhuang)配(pei)：在動、靜環鏡(jing)面(mian)上涂一層(ceng)潔凈的20號潤(run)滑油(you)，導(dao)軸承(cheng)座也抹上潤(run)滑油(you)，先把靜環輕(qing)輕(qing)定(ding)位(wei)裝(zhuang)入(ru)導(dao)軸承(cheng)座，再在泵(beng)軸上抹上潤(run)滑油(you)，把動環部(bu)分輕(qing)輕(qing)裝(zhuang)入(ru)泵(beng)軸上，用手(shou)輕(qing)推密封(feng)環應(ying)能伸縮自如，注意動、靜環部(bu)分的防(fang)轉部(bu)位(wei)需(xu)裝(zhuang)配(pei)到(dao)位(wei)。

　　裝(zhuang)聯(lian)軸(zhou)器(qi)：在電(dian)機軸(zhou)頭上裝(zhuang)上擋圈(quan)(quan)，裝(zhuang)上一(yi)半(ban)聯(lian)軸(zhou)器(qi)，再(zai)在泵軸(zhou)端和聯(lian)軸(zhou)器(qi)槽內(nei)裝(zhuang)上擋塊并用梅花扳手擰緊螺栓(shuan)；再(zai)裝(zhuang)上另(ling)一(yi)半(ban)聯(lian)軸(zhou)器(qi)擰上內(nei)六角(jiao)螺釘(ding)。安裝(zhuang)聯(lian)軸(zhou)器(qi)正確的檢查(cha)要求(qiu)：對分(fen)式聯(lian)軸(zhou)器(qi)上下間(jian)隙需要均勻，用手盤動聯(lian)軸(zhou)器(qi)幾圈(quan)(quan)檢查(cha)轉動的靈活性。

　　裝(zhuang)(zhuang)密(mi)(mi)(mi)封(feng)(feng)(feng)座(zuo)：先將密(mi)(mi)(mi)封(feng)(feng)(feng)座(zuo)裝(zhuang)(zhuang)入(ru)橡膠油封(feng)(feng)(feng)，再把密(mi)(mi)(mi)封(feng)(feng)(feng)座(zuo)裝(zhuang)(zhuang)入(ru)泵蓋(gai)(gai)并壓(ya)在(zai)軸承(cheng)座(zuo)上，擰緊螺(luo)母(mu)，確保所有(you)安(an)裝(zhuang)(zhuang)螺(luo)釘(ding)緊固(gu)。當安(an)裝(zhuang)(zhuang)螺(luo)釘(ding)被用(yong)作密(mi)(mi)(mi)封(feng)(feng)(feng)與軸之(zhi)間的驅動時(shi)，軸應打埋頭孔來加固(gu)連接，緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)應該平穩緊固(gu)，并且不要使壓(ya)蓋(gai)(gai)受(shou)彈力。在(zai)可能(neng)的地方使用(yong)4個以上螺(luo)釘(ding)的等間距(ju)壓(ya)蓋(gai)(gai)，緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)，用(yong)塞尺檢查軸與壓(ya)蓋(gai)(gai)之(zhi)間的間隙，這在(zai)密(mi)(mi)(mi)封(feng)(feng)(feng)腔對壓(ya)蓋(gai)(gai)不導向時(shi)，顯得特別重(zhong)要，因(yin)為(wei)壓(ya)蓋(gai)(gai)必須對中。
