喀什機械密封利用(yong)(yong)(yong)機(ji)械方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)，機(ji)械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)在(zai)機(ji)械工(gong)程中應用(yong)(yong)(yong)非常廣泛，有多種形(xing)式，主(zhu)要(yao)包括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、蝸(gua)(gua)桿(gan)蝸(gua)(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和(he)螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)能(neng)(neng)夠(gou)用(yong)(yong)(yong)于大功(gong)率的(de)(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比(bi)(bi)準確，但一般要(yao)求(qiu)較高的(de)(de)制造精度和(he)安(an)裝精度。還有一類是(shi)靠機(ji)件間的(de)(de)摩(mo)擦力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)的(de)(de)摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和(he)摩(mo)擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)容易實現(xian)無(wu)級變速，可以適應軸(zhou)間距(ju)較大的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)場(chang)合，而過載打(da)滑還能(neng)(neng)起到緩沖(chong)和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)裝置的(de)(de)作(zuo)用(yong)(yong)(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)一般不能(neng)(neng)用(yong)(yong)(yong)于大功(gong)率的(de)(de)場(chang)合，也不能(neng)(neng)保證(zheng)準確的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比(bi)(bi)。

　　傳動形式多，但是喀什機械密封的更換工(gong)作大同小(xiao)異，首先拆(chai)前需確認電機處于檢修狀(zhuang)態，擰下加油(you)(you)螺塞，用吸(xi)管把密封座腔內的潤滑油(you)(you)吸(xi)出。準(zhun)備好放置泵(beng)零件的工(gong)作臺及(ji)拆(chai)裝工(gong)具(ju)，切勿任意(yi)亂放亂用，避免(mian)碰壞泵(beng)的零部件。

　　拆(chai)對分(fen)式聯(lian)軸(zhou)器(qi)(qi)：先把聯(lian)軸(zhou)器(qi)(qi)的固(gu)定內六(liu)角螺釘擰下來(lai)，再(zai)輕輕把聯(lian)軸(zhou)器(qi)(qi)的一半從軸(zhou)上慢(man)慢(man)拉下，注意不要(yao)掉了，再(zai)用梅花扳手(shou)擰下泵(beng)軸(zhou)吊緊螺栓和擋(dang)塊，讓葉輪(lun)慢(man)慢(man)下沉至泵(beng)體(ti)，然后(hou)拆(chai)下另外(wai)一半聯(lian)軸(zhou)器(qi)(qi)，拿下泵(beng)軸(zhou)擋(dang)圈。

　　拆卸喀什機械密封：抓住密封彈簧順著泵軸往上提，就能拆下來了。

　　拆卸并(bing)清洗軸(zhou)承座(zuo)(zuo)：先輕輕松動一下軸(zhou)承座(zuo)(zuo)后(hou)用(yong)拆卸螺栓(shuan)頂起軸(zhou)承座(zuo)(zuo)，并(bing)且沿著泵軸(zhou)往上提而(er)卸下，再用(yong)噴(pen)氣(qi)燃料清洗軸(zhou)承及座(zuo)(zuo)，裝前晾(liang)干并(bing)涂(tu)抹少許(xu)20號機械油用(yong)來潤滑(hua)保護。

　　拆密封(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。

　　喀什機械密封裝(zhuang)配：在(zai)動、靜(jing)環(huan)(huan)鏡面上(shang)涂一層潔凈的20號(hao)潤(run)滑(hua)油(you)，導(dao)(dao)軸(zhou)承座也(ye)抹上(shang)潤(run)滑(hua)油(you)，先(xian)把(ba)靜(jing)環(huan)(huan)輕(qing)(qing)輕(qing)(qing)定位(wei)(wei)(wei)裝(zhuang)入(ru)導(dao)(dao)軸(zhou)承座，再在(zai)泵軸(zhou)上(shang)抹上(shang)潤(run)滑(hua)油(you)，把(ba)動環(huan)(huan)部分(fen)輕(qing)(qing)輕(qing)(qing)裝(zhuang)入(ru)泵軸(zhou)上(shang)，用手(shou)輕(qing)(qing)推密封環(huan)(huan)應能(neng)伸縮自如，注意動、靜(jing)環(huan)(huan)部分(fen)的防轉(zhuan)部位(wei)(wei)(wei)需裝(zhuang)配到位(wei)(wei)(wei)。

　　裝(zhuang)(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)(qi)：在(zai)(zai)電(dian)機軸(zhou)頭上裝(zhuang)(zhuang)(zhuang)(zhuang)上擋圈(quan)，裝(zhuang)(zhuang)(zhuang)(zhuang)上一半聯(lian)軸(zhou)器(qi)(qi)，再在(zai)(zai)泵軸(zhou)端和(he)聯(lian)軸(zhou)器(qi)(qi)槽(cao)內(nei)裝(zhuang)(zhuang)(zhuang)(zhuang)上擋塊并用(yong)梅花扳手(shou)擰(ning)緊螺栓；再裝(zhuang)(zhuang)(zhuang)(zhuang)上另一半聯(lian)軸(zhou)器(qi)(qi)擰(ning)上內(nei)六角螺釘。安裝(zhuang)(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)(qi)正(zheng)確的檢查要求：對(dui)分式(shi)聯(lian)軸(zhou)器(qi)(qi)上下間(jian)隙需(xu)要均(jun)勻(yun)，用(yong)手(shou)盤動聯(lian)軸(zhou)器(qi)(qi)幾(ji)圈(quan)檢查轉動的靈(ling)活性(xing)。

　　裝(zhuang)(zhuang)密封座(zuo)(zuo)：先將(jiang)密封座(zuo)(zuo)裝(zhuang)(zhuang)入橡(xiang)膠油封，再(zai)把密封座(zuo)(zuo)裝(zhuang)(zhuang)入泵蓋(gai)并壓(ya)在軸(zhou)承座(zuo)(zuo)上，擰緊(jin)螺(luo)母，確保所(suo)有安裝(zhuang)(zhuang)螺(luo)釘(ding)緊(jin)固。當安裝(zhuang)(zhuang)螺(luo)釘(ding)被用(yong)作密封與軸(zhou)之間(jian)的(de)驅動時(shi)，軸(zhou)應打埋頭(tou)孔來(lai)加固連(lian)接，緊(jin)固壓(ya)蓋(gai)螺(luo)栓時(shi)應該平穩緊(jin)固，并且不(bu)要(yao)使壓(ya)蓋(gai)受彈力。在可能的(de)地方使用(yong)4個(ge)以上螺(luo)釘(ding)的(de)等間(jian)距壓(ya)蓋(gai)，緊(jin)固壓(ya)蓋(gai)螺(luo)栓時(shi)，用(yong)塞尺檢查軸(zhou)與壓(ya)蓋(gai)之間(jian)的(de)間(jian)隙，這在密封腔對壓(ya)蓋(gai)不(bu)導向時(shi)，顯得特(te)別(bie)重要(yao)，因為壓(ya)蓋(gai)必須對中。
