金牛機械密封利用(yong)機械方(fang)式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械工程中應用(yong)非常(chang)廣(guang)泛，有多種形式，主要(yao)(yao)包(bao)括(kuo)皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋(xuan)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)(neng)夠用(yong)于大功(gong)率的(de)場(chang)(chang)合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準(zhun)確，但(dan)(dan)一(yi)般要(yao)(yao)求(qiu)較高的(de)制造(zao)精度(du)和(he)安裝精度(du)。還有一(yi)類是(shi)靠機件(jian)間(jian)的(de)摩擦力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包(bao)括(kuo)帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)摩擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級(ji)變速，可以適應軸(zhou)間(jian)距較大的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場(chang)(chang)合，而過載(zai)打(da)滑還能(neng)(neng)起(qi)到(dao)緩沖(chong)和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(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)一(yi)般不能(neng)(neng)用(yong)于大功(gong)率的(de)場(chang)(chang)合，也不能(neng)(neng)保證準(zhun)確的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是金牛機械密封的更換工(gong)作大同(tong)小異(yi)，首(shou)先拆前需確(que)認電機處于檢修狀態，擰下加油螺塞，用(yong)(yong)吸(xi)管把密(mi)封座腔內的潤滑油吸(xi)出。準備好(hao)放置泵(beng)(beng)零件的工(gong)作臺(tai)及拆裝工(gong)具，切勿任意(yi)亂(luan)放亂(luan)用(yong)(yong)，避免碰壞泵(beng)(beng)的零部件。

　　拆對分式聯(lian)軸(zhou)器(qi)(qi)：先把聯(lian)軸(zhou)器(qi)(qi)的(de)固定內六角螺釘擰(ning)(ning)下來，再輕(qing)輕(qing)把聯(lian)軸(zhou)器(qi)(qi)的(de)一(yi)(yi)半從軸(zhou)上慢慢拉(la)下，注意(yi)不(bu)要掉了(le)，再用梅花扳手擰(ning)(ning)下泵(beng)軸(zhou)吊緊螺栓和(he)擋塊(kuai)，讓(rang)葉輪(lun)慢慢下沉至泵(beng)體，然后拆下另(ling)外(wai)一(yi)(yi)半聯(lian)軸(zhou)器(qi)(qi)，拿(na)下泵(beng)軸(zhou)擋圈。

　　拆卸金牛機械密封：抓住密封彈簧順著泵(beng)軸往(wang)上提，就能(neng)拆下來了(le)。

　　拆卸并(bing)清洗軸(zhou)承(cheng)(cheng)(cheng)座(zuo)：先輕輕松動一下軸(zhou)承(cheng)(cheng)(cheng)座(zuo)后用(yong)拆卸螺栓頂起(qi)軸(zhou)承(cheng)(cheng)(cheng)座(zuo)，并(bing)且(qie)沿著(zhu)泵軸(zhou)往上提而卸下，再用(yong)噴氣燃料清洗軸(zhou)承(cheng)(cheng)(cheng)及座(zuo)，裝前晾干(gan)并(bing)涂抹少許(xu)20號(hao)機械(xie)油用(yong)來潤(run)滑保護。

　　拆密封(feng)座：擰下密封(feng)座壓緊(jin)螺母，輕(qing)輕(qing)卸下密封(feng)座并(bing)清洗。

　　金牛機械密封裝(zhuang)(zhuang)(zhuang)配：在動(dong)、靜(jing)環鏡面上(shang)涂一層潔(jie)凈(jing)的20號潤滑(hua)油(you)，導軸承座也抹(mo)(mo)上(shang)潤滑(hua)油(you)，先把(ba)靜(jing)環輕(qing)(qing)輕(qing)(qing)定位裝(zhuang)(zhuang)(zhuang)入(ru)導軸承座，再(zai)在泵(beng)軸上(shang)抹(mo)(mo)上(shang)潤滑(hua)油(you)，把(ba)動(dong)環部(bu)分輕(qing)(qing)輕(qing)(qing)裝(zhuang)(zhuang)(zhuang)入(ru)泵(beng)軸上(shang)，用手輕(qing)(qing)推密封(feng)環應能伸縮自(zi)如(ru)，注意動(dong)、靜(jing)環部(bu)分的防轉部(bu)位需裝(zhuang)(zhuang)(zhuang)配到位。

　　裝(zhuang)聯(lian)軸(zhou)器(qi)(qi)：在(zai)電機軸(zhou)頭上裝(zhuang)上擋圈，裝(zhuang)上一半(ban)聯(lian)軸(zhou)器(qi)(qi)，再在(zai)泵(beng)軸(zhou)端和聯(lian)軸(zhou)器(qi)(qi)槽內裝(zhuang)上擋塊(kuai)并用梅花扳(ban)手擰緊螺(luo)(luo)栓(shuan)；再裝(zhuang)上另一半(ban)聯(lian)軸(zhou)器(qi)(qi)擰上內六角螺(luo)(luo)釘。安裝(zhuang)聯(lian)軸(zhou)器(qi)(qi)正(zheng)確的(de)檢查要(yao)求：對分式聯(lian)軸(zhou)器(qi)(qi)上下間隙需要(yao)均勻，用手盤動聯(lian)軸(zhou)器(qi)(qi)幾(ji)圈檢查轉動的(de)靈活性。

　　裝(zhuang)密(mi)封座(zuo)：先將密(mi)封座(zuo)裝(zhuang)入橡(xiang)膠油(you)封，再把密(mi)封座(zuo)裝(zhuang)入泵蓋(gai)并壓(ya)在(zai)軸承(cheng)座(zuo)上(shang)，擰(ning)緊(jin)螺(luo)母，確保所有安裝(zhuang)螺(luo)釘緊(jin)固。當安裝(zhuang)螺(luo)釘被(bei)用(yong)作(zuo)密(mi)封與軸之間的驅動時，軸應(ying)打埋頭孔來加固連接，緊(jin)固壓(ya)蓋(gai)螺(luo)栓時應(ying)該平穩緊(jin)固，并且不(bu)要使(shi)壓(ya)蓋(gai)受(shou)彈力。在(zai)可能的地方(fang)使(shi)用(yong)4個(ge)以上(shang)螺(luo)釘的等間距壓(ya)蓋(gai)，緊(jin)固壓(ya)蓋(gai)螺(luo)栓時，用(yong)塞尺(chi)檢查軸與壓(ya)蓋(gai)之間的間隙(xi)，這在(zai)密(mi)封腔對壓(ya)蓋(gai)不(bu)導向(xiang)時，顯得特別重要，因(yin)為壓(ya)蓋(gai)必須對中。
