東英鎮機械密封利用(yong)(yong)機(ji)(ji)械(xie)(xie)方式(shi)傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)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)程中應用(yong)(yong)非常廣泛，有(you)多種形式(shi)，主要(yao)包括皮帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)齒(chi)條(tiao)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)(neng)夠(gou)用(yong)(yong)于大(da)(da)功(gong)率的(de)(de)(de)場合(he)(he)，傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)準確，但(dan)一般要(yao)求較高的(de)(de)(de)制造精度(du)(du)和(he)安裝精度(du)(du)。還(huan)有(you)一類(lei)是靠機(ji)(ji)件間(jian)的(de)(de)(de)摩(mo)擦(ca)(ca)力傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩(mo)擦(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(mo)擦(ca)(ca)輪(lun)(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)(ca)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實現無級變(bian)速，可以適應軸(zhou)間(jian)距較大(da)(da)的(de)(de)(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場合(he)(he)，而(er)過載(zai)打滑(hua)還(huan)能(neng)(neng)起到緩沖和(he)保護傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置(zhi)的(de)(de)(de)作用(yong)(yong)，但(dan)這種傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一般不(bu)能(neng)(neng)用(yong)(yong)于大(da)(da)功(gong)率的(de)(de)(de)場合(he)(he)，也不(bu)能(neng)(neng)保證準確的(de)(de)(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是東英鎮機械密封的更換工(gong)(gong)作(zuo)大(da)同小(xiao)異，首先拆前(qian)需確(que)認電機處于檢修狀態，擰(ning)下加油螺塞，用吸(xi)管把(ba)密(mi)封(feng)座(zuo)腔內的潤滑油吸(xi)出。準備好(hao)放置(zhi)泵(beng)零件(jian)的工(gong)(gong)作(zuo)臺及(ji)拆裝工(gong)(gong)具，切勿任意亂(luan)放亂(luan)用，避免碰壞泵(beng)的零部(bu)件(jian)。

　　拆對分(fen)式聯(lian)軸(zhou)(zhou)(zhou)器：先把聯(lian)軸(zhou)(zhou)(zhou)器的(de)固定內六角螺釘(ding)擰(ning)下(xia)來，再(zai)(zai)輕(qing)輕(qing)把聯(lian)軸(zhou)(zhou)(zhou)器的(de)一(yi)半(ban)從(cong)軸(zhou)(zhou)(zhou)上(shang)慢(man)慢(man)拉下(xia)，注(zhu)意(yi)不要掉了，再(zai)(zai)用梅花扳手擰(ning)下(xia)泵軸(zhou)(zhou)(zhou)吊緊螺栓和擋塊，讓葉(xie)輪慢(man)慢(man)下(xia)沉至(zhi)泵體，然后拆下(xia)另外一(yi)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器，拿(na)下(xia)泵軸(zhou)(zhou)(zhou)擋圈。

　　拆卸東英鎮機械密封：抓住密(mi)封彈簧順著泵軸往上提，就能拆下來了(le)。

　　拆卸并(bing)(bing)(bing)清洗軸(zhou)(zhou)承(cheng)座(zuo)：先輕輕松動(dong)一下軸(zhou)(zhou)承(cheng)座(zuo)后用(yong)拆卸螺栓頂起軸(zhou)(zhou)承(cheng)座(zuo)，并(bing)(bing)(bing)且沿著泵(beng)軸(zhou)(zhou)往上提而卸下，再用(yong)噴氣燃(ran)料清洗軸(zhou)(zhou)承(cheng)及座(zuo)，裝前晾干(gan)并(bing)(bing)(bing)涂抹少許20號機(ji)械(xie)油(you)用(yong)來潤(run)滑(hua)保護。

　　拆密(mi)封座：擰下密(mi)封座壓緊螺母，輕輕卸下密(mi)封座并清洗。

　　東英鎮機械密封裝配：在(zai)動(dong)、靜(jing)環鏡面上涂(tu)一層潔凈(jing)的20號潤滑(hua)油，導軸(zhou)承座(zuo)也抹上潤滑(hua)油，先把靜(jing)環輕(qing)輕(qing)定位裝入導軸(zhou)承座(zuo)，再在(zai)泵軸(zhou)上抹上潤滑(hua)油，把動(dong)環部分(fen)(fen)輕(qing)輕(qing)裝入泵軸(zhou)上，用(yong)手輕(qing)推密(mi)封(feng)環應能(neng)伸縮自如(ru)，注意(yi)動(dong)、靜(jing)環部分(fen)(fen)的防轉部位需裝配到位。

　　裝(zhuang)(zhuang)聯(lian)軸器(qi)：在電機軸頭上(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)擋圈，裝(zhuang)(zhuang)上(shang)(shang)一(yi)半聯(lian)軸器(qi)，再在泵軸端和聯(lian)軸器(qi)槽內(nei)裝(zhuang)(zhuang)上(shang)(shang)擋塊(kuai)并用梅(mei)花(hua)扳(ban)手擰緊螺(luo)栓；再裝(zhuang)(zhuang)上(shang)(shang)另一(yi)半聯(lian)軸器(qi)擰上(shang)(shang)內(nei)六(liu)角螺(luo)釘。安裝(zhuang)(zhuang)聯(lian)軸器(qi)正(zheng)確(que)的檢查要求：對分式聯(lian)軸器(qi)上(shang)(shang)下間隙(xi)需要均勻，用手盤(pan)動聯(lian)軸器(qi)幾圈檢查轉動的靈活性。

　　裝密(mi)封(feng)(feng)座：先將(jiang)密(mi)封(feng)(feng)座裝入(ru)橡膠油封(feng)(feng)，再把(ba)密(mi)封(feng)(feng)座裝入(ru)泵(beng)蓋并(bing)壓(ya)在(zai)軸承座上(shang)，擰緊(jin)(jin)(jin)螺(luo)母，確保所有安(an)裝螺(luo)釘緊(jin)(jin)(jin)固(gu)(gu)。當(dang)安(an)裝螺(luo)釘被用(yong)作密(mi)封(feng)(feng)與(yu)軸之間(jian)的(de)驅動時(shi)，軸應(ying)打埋(mai)頭孔(kong)來加(jia)固(gu)(gu)連接(jie)，緊(jin)(jin)(jin)固(gu)(gu)壓(ya)蓋螺(luo)栓時(shi)應(ying)該平穩(wen)緊(jin)(jin)(jin)固(gu)(gu)，并(bing)且(qie)不要(yao)使壓(ya)蓋受彈力。在(zai)可能(neng)的(de)地方使用(yong)4個以上(shang)螺(luo)釘的(de)等(deng)間(jian)距(ju)壓(ya)蓋，緊(jin)(jin)(jin)固(gu)(gu)壓(ya)蓋螺(luo)栓時(shi)，用(yong)塞尺(chi)檢(jian)查軸與(yu)壓(ya)蓋之間(jian)的(de)間(jian)隙，這在(zai)密(mi)封(feng)(feng)腔對壓(ya)蓋不導(dao)向時(shi)，顯得特別(bie)重要(yao)，因為(wei)壓(ya)蓋必須(xu)對中。
