額敏機械密封利用機(ji)械(xie)方式(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)械(xie)工程中(zhong)應用非常(chang)廣泛，有多種形式(shi)，主要(yao)包(bao)括(kuo)皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)(lun)(lun)齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。齒輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用于大功率的(de)(de)(de)場合(he)，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比準確，但一般(ban)要(yao)求(qiu)較高的(de)(de)(de)制造(zao)精度和(he)安裝精度。還有一類是靠機(ji)件(jian)間的(de)(de)(de)摩(mo)擦(ca)(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)(de)(de)摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包(bao)括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩(sheng)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)摩(mo)擦(ca)(ca)輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易(yi)實現無級(ji)變速，可以適應軸間距較大的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合(he)，而(er)過(guo)載打(da)滑還能起(qi)到(dao)緩沖和(he)保(bao)護(hu)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置的(de)(de)(de)作用，但這(zhe)種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般(ban)不(bu)能用于大功率的(de)(de)(de)場合(he)，也(ye)不(bu)能保(bao)證準確的(de)(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是額敏機械密封的(de)更換工(gong)作(zuo)大同小異，首先(xian)拆前需確(que)認電機(ji)處于檢修狀(zhuang)態，擰下加油螺塞，用吸管把(ba)密封座腔內的(de)潤滑油吸出。準(zhun)備好放置泵(beng)零件(jian)(jian)的(de)工(gong)作(zuo)臺及(ji)拆裝工(gong)具，切(qie)勿(wu)任意亂放亂用，避免(mian)碰壞(huai)泵(beng)的(de)零部件(jian)(jian)。

　　拆(chai)對分式(shi)聯(lian)軸(zhou)(zhou)(zhou)器(qi)：先把(ba)(ba)聯(lian)軸(zhou)(zhou)(zhou)器(qi)的(de)固(gu)定內六角螺釘擰(ning)下來，再輕(qing)輕(qing)把(ba)(ba)聯(lian)軸(zhou)(zhou)(zhou)器(qi)的(de)一(yi)半(ban)從(cong)軸(zhou)(zhou)(zhou)上慢(man)(man)慢(man)(man)拉下，注(zhu)意(yi)不要掉了，再用梅花(hua)扳(ban)手擰(ning)下泵(beng)軸(zhou)(zhou)(zhou)吊緊螺栓和擋塊，讓葉輪慢(man)(man)慢(man)(man)下沉至泵(beng)體，然后拆(chai)下另外一(yi)半(ban)聯(lian)軸(zhou)(zhou)(zhou)器(qi)，拿(na)下泵(beng)軸(zhou)(zhou)(zhou)擋圈。

　　拆卸額敏機械密封：抓住密封彈簧順著泵軸往上提，就能拆下來(lai)了(le)。

　　拆卸并(bing)清洗軸(zhou)(zhou)承(cheng)座：先輕輕松動一下軸(zhou)(zhou)承(cheng)座后用拆卸螺栓頂起軸(zhou)(zhou)承(cheng)座，并(bing)且沿著泵軸(zhou)(zhou)往上提而卸下，再用噴氣燃料清洗軸(zhou)(zhou)承(cheng)及座，裝前晾干(gan)并(bing)涂抹少許20號機械油用來潤(run)滑保(bao)護。

　　拆(chai)密封(feng)座：擰下(xia)(xia)密封(feng)座壓緊螺母，輕輕卸下(xia)(xia)密封(feng)座并清洗(xi)。

　　額敏機械密封裝(zhuang)配：在(zai)動(dong)、靜(jing)環(huan)鏡面(mian)上(shang)涂一層潔凈的20號潤滑(hua)油，導(dao)軸承座也(ye)抹(mo)上(shang)潤滑(hua)油，先(xian)把靜(jing)環(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)入導(dao)軸承座，再(zai)在(zai)泵軸上(shang)抹(mo)上(shang)潤滑(hua)油，把動(dong)環(huan)部分輕(qing)輕(qing)裝(zhuang)入泵軸上(shang)，用(yong)手輕(qing)推(tui)密封(feng)環(huan)應(ying)能(neng)伸縮自如，注意動(dong)、靜(jing)環(huan)部分的防(fang)轉部位(wei)需裝(zhuang)配到位(wei)。

　　裝(zhuang)(zhuang)(zhuang)聯軸(zhou)(zhou)(zhou)器(qi)(qi)：在電機軸(zhou)(zhou)(zhou)頭(tou)上裝(zhuang)(zhuang)(zhuang)上擋圈，裝(zhuang)(zhuang)(zhuang)上一(yi)半聯軸(zhou)(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)(zhou)端和聯軸(zhou)(zhou)(zhou)器(qi)(qi)槽內裝(zhuang)(zhuang)(zhuang)上擋塊并用梅花扳手擰緊(jin)螺栓；再裝(zhuang)(zhuang)(zhuang)上另一(yi)半聯軸(zhou)(zhou)(zhou)器(qi)(qi)擰上內六(liu)角螺釘。安裝(zhuang)(zhuang)(zhuang)聯軸(zhou)(zhou)(zhou)器(qi)(qi)正確的檢(jian)查要求：對分式聯軸(zhou)(zhou)(zhou)器(qi)(qi)上下(xia)間(jian)隙需要均勻，用手盤(pan)動聯軸(zhou)(zhou)(zhou)器(qi)(qi)幾圈檢(jian)查轉動的靈活(huo)性。

　　裝(zhuang)密封座(zuo)(zuo)：先(xian)將(jiang)密封座(zuo)(zuo)裝(zhuang)入(ru)橡膠油封，再把密封座(zuo)(zuo)裝(zhuang)入(ru)泵蓋(gai)并壓(ya)(ya)在軸承座(zuo)(zuo)上，擰(ning)緊(jin)螺(luo)(luo)(luo)母(mu)，確(que)保所(suo)有安裝(zhuang)螺(luo)(luo)(luo)釘(ding)緊(jin)固(gu)。當安裝(zhuang)螺(luo)(luo)(luo)釘(ding)被用作密封與(yu)軸之(zhi)間的驅(qu)動時(shi)，軸應打埋(mai)頭孔(kong)來加固(gu)連(lian)接，緊(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)(luo)(luo)栓時(shi)應該平穩緊(jin)固(gu)，并且不(bu)要使(shi)壓(ya)(ya)蓋(gai)受彈力。在可(ke)能的地方(fang)使(shi)用4個(ge)以上螺(luo)(luo)(luo)釘(ding)的等間距壓(ya)(ya)蓋(gai)，緊(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)(luo)(luo)栓時(shi)，用塞尺檢查(cha)軸與(yu)壓(ya)(ya)蓋(gai)之(zhi)間的間隙，這(zhe)在密封腔對壓(ya)(ya)蓋(gai)不(bu)導向時(shi)，顯得特(te)別重要，因為壓(ya)(ya)蓋(gai)必(bi)須對中(zhong)。
