麗江機械密封利用(yong)(yong)(yong)機(ji)械方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械工程中應用(yong)(yong)(yong)非常(chang)廣泛，有多(duo)種(zhong)形式，主(zhu)要包括皮帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)(lun)齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺(luo)旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)(neng)夠用(yong)(yong)(yong)于大(da)功(gong)率的(de)(de)(de)場合，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)準確(que)，但一(yi)般(ban)要求(qiu)較(jiao)高的(de)(de)(de)制造精度(du)和(he)安裝(zhuang)精度(du)。還有一(yi)類是靠機(ji)件間的(de)(de)(de)摩(mo)擦(ca)力傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)(de)(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括帶(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)摩(mo)擦(ca)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易實現無級變速，可以適應軸間距(ju)較(jiao)大(da)的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場合，而過(guo)載打滑還能(neng)(neng)起到緩沖和(he)保(bao)護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的(de)(de)(de)作用(yong)(yong)(yong)，但這種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)不能(neng)(neng)用(yong)(yong)(yong)于大(da)功(gong)率的(de)(de)(de)場合，也不能(neng)(neng)保(bao)證(zheng)準確(que)的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是麗江機械密封的更換(huan)工作大同(tong)小(xiao)異，首先拆(chai)前(qian)需確認電機處于檢修狀態，擰下加(jia)油螺(luo)塞，用吸(xi)管把密封座腔內(nei)的潤(run)滑油吸(xi)出。準備好放置泵零(ling)件的工作臺及拆(chai)裝工具(ju)，切勿任意亂放亂用，避免碰(peng)壞泵的零(ling)部件。

　　拆對分(fen)式聯(lian)軸(zhou)(zhou)器(qi)：先把聯(lian)軸(zhou)(zhou)器(qi)的(de)固定內六角螺釘擰下(xia)(xia)(xia)來，再輕輕把聯(lian)軸(zhou)(zhou)器(qi)的(de)一(yi)半從(cong)軸(zhou)(zhou)上慢慢拉下(xia)(xia)(xia)，注(zhu)意不要掉了，再用(yong)梅花扳手擰下(xia)(xia)(xia)泵軸(zhou)(zhou)吊緊螺栓和擋塊(kuai)，讓(rang)葉輪(lun)慢慢下(xia)(xia)(xia)沉至泵體，然后拆下(xia)(xia)(xia)另(ling)外一(yi)半聯(lian)軸(zhou)(zhou)器(qi)，拿下(xia)(xia)(xia)泵軸(zhou)(zhou)擋圈。

　　拆卸麗江機械密封：抓(zhua)住密(mi)封彈簧順著泵軸(zhou)往上提(ti)，就能拆下來了。

　　拆卸并(bing)清洗軸(zhou)(zhou)承座(zuo)：先輕輕松動一下軸(zhou)(zhou)承座(zuo)后用拆卸螺栓頂起軸(zhou)(zhou)承座(zuo)，并(bing)且沿著泵軸(zhou)(zhou)往上提(ti)而卸下，再用噴氣燃料清洗軸(zhou)(zhou)承及座(zuo)，裝(zhuang)前晾干并(bing)涂抹(mo)少許20號機(ji)械油用來潤(run)滑保護(hu)。

　　拆密封座：擰下密封座壓緊螺母，輕輕卸下密封座并清(qing)洗。

　　麗江機械密封裝配(pei)：在(zai)動(dong)(dong)、靜環(huan)鏡面上涂一層(ceng)潔凈的20號(hao)潤滑油，導軸(zhou)承座(zuo)也抹上潤滑油，先把靜環(huan)輕(qing)輕(qing)定(ding)位裝入導軸(zhou)承座(zuo)，再在(zai)泵(beng)軸(zhou)上抹上潤滑油，把動(dong)(dong)環(huan)部分輕(qing)輕(qing)裝入泵(beng)軸(zhou)上，用(yong)手輕(qing)推密封環(huan)應能伸(shen)縮(suo)自(zi)如，注(zhu)意動(dong)(dong)、靜環(huan)部分的防(fang)轉部位需裝配(pei)到(dao)位。

　　裝(zhuang)(zhuang)聯(lian)軸(zhou)器：在(zai)電(dian)機(ji)軸(zhou)頭上裝(zhuang)(zhuang)上擋圈(quan)，裝(zhuang)(zhuang)上一半聯(lian)軸(zhou)器，再在(zai)泵軸(zhou)端和聯(lian)軸(zhou)器槽內裝(zhuang)(zhuang)上擋塊并(bing)用梅花(hua)扳手(shou)擰緊螺(luo)栓；再裝(zhuang)(zhuang)上另一半聯(lian)軸(zhou)器擰上內六角螺(luo)釘。安裝(zhuang)(zhuang)聯(lian)軸(zhou)器正確的檢查要求：對分式聯(lian)軸(zhou)器上下間隙需要均勻(yun)，用手(shou)盤動(dong)聯(lian)軸(zhou)器幾圈(quan)檢查轉(zhuan)動(dong)的靈活性(xing)。

　　裝(zhuang)(zhuang)密(mi)(mi)封(feng)座(zuo)：先將密(mi)(mi)封(feng)座(zuo)裝(zhuang)(zhuang)入橡(xiang)膠油封(feng)，再把密(mi)(mi)封(feng)座(zuo)裝(zhuang)(zhuang)入泵蓋(gai)(gai)并壓(ya)(ya)在(zai)軸承座(zuo)上，擰緊(jin)螺(luo)(luo)母，確(que)保所(suo)有安(an)裝(zhuang)(zhuang)螺(luo)(luo)釘(ding)緊(jin)固(gu)(gu)。當安(an)裝(zhuang)(zhuang)螺(luo)(luo)釘(ding)被用作密(mi)(mi)封(feng)與(yu)軸之間(jian)的(de)驅動時(shi)，軸應(ying)(ying)打(da)埋頭孔來加(jia)固(gu)(gu)連(lian)接，緊(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)(luo)栓(shuan)時(shi)應(ying)(ying)該(gai)平穩緊(jin)固(gu)(gu)，并且不(bu)要使壓(ya)(ya)蓋(gai)(gai)受彈(dan)力。在(zai)可能的(de)地方(fang)使用4個以上螺(luo)(luo)釘(ding)的(de)等間(jian)距(ju)壓(ya)(ya)蓋(gai)(gai)，緊(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)(luo)栓(shuan)時(shi)，用塞尺(chi)檢(jian)查(cha)軸與(yu)壓(ya)(ya)蓋(gai)(gai)之間(jian)的(de)間(jian)隙(xi)，這(zhe)在(zai)密(mi)(mi)封(feng)腔對(dui)壓(ya)(ya)蓋(gai)(gai)不(bu)導向時(shi)，顯得(de)特別(bie)重要，因為壓(ya)(ya)蓋(gai)(gai)必須對(dui)中。
