措美機械密封利(li)用(yong)機(ji)械方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)械工程中應用(yong)非常(chang)廣泛，有多種形式，主要包括(kuo)(kuo)皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)輪傳(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(gan)蝸輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)輪齒(chi)(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用(yong)于大功率的場合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準確(que)，但一般要求較(jiao)高的制造(zao)精(jing)度(du)和(he)(he)安(an)裝精(jing)度(du)。還有一類是靠機(ji)件間的摩擦(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)的摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括(kuo)(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)摩擦(ca)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級(ji)變速(su)，可以適應軸間距(ju)較(jiao)大的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合，而過載打滑還能起(qi)到緩沖和(he)(he)保護(hu)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)的作用(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般不(bu)能用(yong)于大功率的場合，也不(bu)能保證(zheng)準確(que)的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是措美機械密封的更(geng)換工作大同小異，首先拆(chai)前需確認電(dian)機處于檢(jian)修狀態，擰下加油螺塞，用(yong)吸管把密封座腔(qiang)內(nei)的潤滑油吸出(chu)。準(zhun)備好(hao)放(fang)置泵(beng)零(ling)件的工作臺及(ji)拆(chai)裝工具，切(qie)勿任意亂放(fang)亂用(yong)，避免碰壞泵(beng)的零(ling)部件。

　　拆對分式聯軸(zhou)(zhou)(zhou)器：先(xian)把(ba)聯軸(zhou)(zhou)(zhou)器的固(gu)定內六角螺釘(ding)擰(ning)下(xia)來，再(zai)輕輕把(ba)聯軸(zhou)(zhou)(zhou)器的一(yi)半從軸(zhou)(zhou)(zhou)上慢(man)(man)慢(man)(man)拉下(xia)，注意不要(yao)掉了，再(zai)用梅花(hua)扳(ban)手擰(ning)下(xia)泵軸(zhou)(zhou)(zhou)吊緊螺栓和擋(dang)塊，讓葉輪慢(man)(man)慢(man)(man)下(xia)沉(chen)至泵體(ti)，然后拆下(xia)另外一(yi)半聯軸(zhou)(zhou)(zhou)器，拿下(xia)泵軸(zhou)(zhou)(zhou)擋(dang)圈。

　　拆卸措美機械密封：抓住密封彈簧順著泵軸往上提，就能拆下來了。

　　拆(chai)卸并清(qing)洗軸(zhou)(zhou)承座：先輕輕松(song)動一(yi)下(xia)軸(zhou)(zhou)承座后用(yong)拆(chai)卸螺栓(shuan)頂起(qi)軸(zhou)(zhou)承座，并且沿著泵軸(zhou)(zhou)往(wang)上提而卸下(xia)，再用(yong)噴氣燃料清(qing)洗軸(zhou)(zhou)承及(ji)座，裝前晾干并涂抹少許20號機(ji)械油用(yong)來潤滑(hua)保護。

　　拆密封(feng)座：擰下密封(feng)座壓(ya)緊螺母(mu)，輕輕卸下密封(feng)座并(bing)清(qing)洗(xi)。

　　措美機械密封裝(zhuang)配：在動(dong)、靜環(huan)(huan)鏡面上涂一(yi)層潔(jie)凈的20號潤(run)(run)滑(hua)油(you)(you)，導軸承(cheng)座也抹上潤(run)(run)滑(hua)油(you)(you)，先把靜環(huan)(huan)輕(qing)(qing)輕(qing)(qing)定位裝(zhuang)入(ru)導軸承(cheng)座，再(zai)在泵軸上抹上潤(run)(run)滑(hua)油(you)(you)，把動(dong)環(huan)(huan)部(bu)分輕(qing)(qing)輕(qing)(qing)裝(zhuang)入(ru)泵軸上，用手輕(qing)(qing)推(tui)密封環(huan)(huan)應能伸(shen)縮自(zi)如，注意動(dong)、靜環(huan)(huan)部(bu)分的防轉部(bu)位需裝(zhuang)配到位。

　　裝(zhuang)聯軸(zhou)(zhou)器(qi)(qi)(qi)：在電(dian)機軸(zhou)(zhou)頭上裝(zhuang)上擋(dang)圈，裝(zhuang)上一半聯軸(zhou)(zhou)器(qi)(qi)(qi)，再在泵軸(zhou)(zhou)端(duan)和(he)聯軸(zhou)(zhou)器(qi)(qi)(qi)槽內裝(zhuang)上擋(dang)塊(kuai)并用(yong)梅花扳手擰緊(jin)螺(luo)(luo)栓(shuan)；再裝(zhuang)上另一半聯軸(zhou)(zhou)器(qi)(qi)(qi)擰上內六角螺(luo)(luo)釘。安(an)裝(zhuang)聯軸(zhou)(zhou)器(qi)(qi)(qi)正確的檢(jian)查要求(qiu)：對分式(shi)聯軸(zhou)(zhou)器(qi)(qi)(qi)上下間隙(xi)需要均勻，用(yong)手盤動(dong)(dong)聯軸(zhou)(zhou)器(qi)(qi)(qi)幾圈檢(jian)查轉動(dong)(dong)的靈活(huo)性。

　　裝密封座(zuo)：先將密封座(zuo)裝入(ru)橡(xiang)膠(jiao)油(you)封，再把密封座(zuo)裝入(ru)泵蓋(gai)并(bing)壓(ya)在(zai)軸承座(zuo)上，擰緊螺母(mu)，確保所(suo)有安裝螺釘緊固。當安裝螺釘被用(yong)(yong)作密封與(yu)軸之間的驅動時(shi)，軸應(ying)打埋頭孔來加固連接，緊固壓(ya)蓋(gai)螺栓時(shi)應(ying)該平穩緊固，并(bing)且不要(yao)使壓(ya)蓋(gai)受彈(dan)力。在(zai)可能的地方使用(yong)(yong)4個(ge)以上螺釘的等間距壓(ya)蓋(gai)，緊固壓(ya)蓋(gai)螺栓時(shi)，用(yong)(yong)塞尺檢查軸與(yu)壓(ya)蓋(gai)之間的間隙，這(zhe)在(zai)密封腔對壓(ya)蓋(gai)不導向(xiang)時(shi)，顯得特別重(zhong)要(yao)，因為壓(ya)蓋(gai)必須對中(zhong)。
