卓尼機械密封利(li)用機械(xie)方式傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)(he)(he)運動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機械(xie)工(gong)程中應用非常廣泛，有多種(zhong)形式，主要(yao)包(bao)括皮帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿(gan)蝸(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)(he)螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠用于(yu)大功率的(de)場合(he)(he)，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)準(zhun)確，但一(yi)(yi)般要(yao)求較高(gao)的(de)制造精度(du)和(he)(he)(he)安(an)裝精度(du)。還有一(yi)(yi)類是靠機件間(jian)的(de)摩(mo)(mo)擦力傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)(he)(he)運動(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包(bao)括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)(he)摩(mo)(mo)擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容(rong)易實現無級(ji)變速，可(ke)以適應軸間(jian)距較大的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場合(he)(he)，而過(guo)載打(da)滑還能(neng)起(qi)到緩沖(chong)和(he)(he)(he)保(bao)護(hu)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的(de)作用，但這種(zhong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)(yi)般不(bu)能(neng)用于(yu)大功率的(de)場合(he)(he)，也不(bu)能(neng)保(bao)證準(zhun)確的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是卓尼機械密封的(de)更換工作大同小異，首先拆(chai)前(qian)需(xu)確認電機處于檢修(xiu)狀(zhuang)態，擰下加油螺塞，用吸(xi)管把(ba)密封座腔內的(de)潤(run)滑油吸(xi)出(chu)。準備好(hao)放置泵(beng)零件(jian)的(de)工作臺及拆(chai)裝(zhuang)工具，切勿任意亂(luan)放亂(luan)用，避(bi)免碰壞泵(beng)的(de)零部(bu)件(jian)。

　　拆對(dui)分式聯(lian)軸(zhou)器(qi)：先把(ba)聯(lian)軸(zhou)器(qi)的(de)固定內(nei)六角螺(luo)釘(ding)擰下(xia)(xia)來，再(zai)(zai)輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)器(qi)的(de)一(yi)半從軸(zhou)上慢慢拉下(xia)(xia)，注意不(bu)要掉了，再(zai)(zai)用梅花(hua)扳手擰下(xia)(xia)泵(beng)軸(zhou)吊緊螺(luo)栓和擋(dang)塊，讓葉(xie)輪慢慢下(xia)(xia)沉至泵(beng)體(ti)，然后拆下(xia)(xia)另外一(yi)半聯(lian)軸(zhou)器(qi)，拿(na)下(xia)(xia)泵(beng)軸(zhou)擋(dang)圈。

　　拆卸卓尼機械密封：抓(zhua)住密封彈(dan)簧順(shun)著泵(beng)軸往(wang)上提(ti)，就能拆(chai)下來了。

　　拆卸并清洗軸承(cheng)(cheng)座(zuo)(zuo)：先輕(qing)輕(qing)松動一下軸承(cheng)(cheng)座(zuo)(zuo)后用拆卸螺栓頂起軸承(cheng)(cheng)座(zuo)(zuo)，并且沿著泵軸往(wang)上提而卸下，再用噴氣(qi)燃料清洗軸承(cheng)(cheng)及座(zuo)(zuo)，裝前晾干并涂抹少許20號(hao)機械油用來潤滑(hua)保護。

　　拆(chai)密(mi)封(feng)座：擰下(xia)密(mi)封(feng)座壓緊螺母(mu)，輕(qing)輕(qing)卸下(xia)密(mi)封(feng)座并(bing)清洗。

　　卓尼機械密封裝配(pei)(pei)：在(zai)動(dong)(dong)、靜環鏡面(mian)上(shang)(shang)涂(tu)一層(ceng)潔凈的(de)20號潤滑油，導軸(zhou)承座(zuo)也抹上(shang)(shang)潤滑油，先把靜環輕(qing)(qing)輕(qing)(qing)定(ding)位裝入導軸(zhou)承座(zuo)，再在(zai)泵軸(zhou)上(shang)(shang)抹上(shang)(shang)潤滑油，把動(dong)(dong)環部(bu)分輕(qing)(qing)輕(qing)(qing)裝入泵軸(zhou)上(shang)(shang)，用手輕(qing)(qing)推密封環應能伸縮自(zi)如，注(zhu)意動(dong)(dong)、靜環部(bu)分的(de)防(fang)轉部(bu)位需裝配(pei)(pei)到位。

　　裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)(dang)圈，裝(zhuang)上(shang)(shang)一(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)，再(zai)在泵軸(zhou)(zhou)(zhou)端(duan)和(he)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)槽(cao)內裝(zhuang)上(shang)(shang)擋(dang)(dang)塊并用梅花扳手(shou)擰緊螺栓；再(zai)裝(zhuang)上(shang)(shang)另(ling)一(yi)半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)擰上(shang)(shang)內六角螺釘(ding)。安裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)正確(que)的檢查要(yao)求：對(dui)分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)上(shang)(shang)下間隙(xi)需(xu)要(yao)均勻(yun)，用手(shou)盤動聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈檢查轉動的靈活性。

　　裝(zhuang)(zhuang)(zhuang)密封(feng)座(zuo)(zuo)：先將密封(feng)座(zuo)(zuo)裝(zhuang)(zhuang)(zhuang)入橡膠(jiao)油封(feng)，再把密封(feng)座(zuo)(zuo)裝(zhuang)(zhuang)(zhuang)入泵蓋并(bing)壓(ya)在(zai)(zai)(zai)軸承座(zuo)(zuo)上，擰緊(jin)螺(luo)母，確保所有(you)安(an)裝(zhuang)(zhuang)(zhuang)螺(luo)釘緊(jin)固(gu)。當安(an)裝(zhuang)(zhuang)(zhuang)螺(luo)釘被用(yong)(yong)作密封(feng)與(yu)軸之間的驅動時(shi)，軸應打埋頭(tou)孔(kong)來加固(gu)連接，緊(jin)固(gu)壓(ya)蓋螺(luo)栓(shuan)時(shi)應該平穩緊(jin)固(gu)，并(bing)且不要使(shi)壓(ya)蓋受彈力。在(zai)(zai)(zai)可能的地方使(shi)用(yong)(yong)4個以上螺(luo)釘的等(deng)間距(ju)壓(ya)蓋，緊(jin)固(gu)壓(ya)蓋螺(luo)栓(shuan)時(shi)，用(yong)(yong)塞(sai)尺檢查軸與(yu)壓(ya)蓋之間的間隙，這在(zai)(zai)(zai)密封(feng)腔對壓(ya)蓋不導向時(shi)，顯得特(te)別重要，因(yin)為壓(ya)蓋必須對中。
