平遠機械密封利用機(ji)械方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)械工程中應(ying)用非常廣泛，有(you)多種形式，主要(yao)包括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條(tiao)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用于大功率的場(chang)(chang)合(he)，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比準確，但一般要(yao)求(qiu)較高的制(zhi)造精度(du)和(he)(he)安裝精度(du)。還有(you)一類是靠機(ji)件(jian)間的摩擦(ca)力傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)的摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括(kuo)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)摩擦(ca)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變速(su)，可以適應(ying)軸間距較大的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合(he)，而(er)過載打滑還能(neng)起到緩沖和(he)(he)保護(hu)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的作用，但這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一般不能(neng)用于大功率的場(chang)(chang)合(he)，也不能(neng)保證準確的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是平遠機械密封的(de)(de)更換工作(zuo)大同小異，首先拆(chai)前需確認(ren)電機處于檢(jian)修狀態，擰下加油螺塞，用吸管把密封(feng)座腔內的(de)(de)潤滑油吸出(chu)。準備好放置泵(beng)零件的(de)(de)工作(zuo)臺及(ji)拆(chai)裝工具，切勿任(ren)意亂放亂用，避免碰壞泵(beng)的(de)(de)零部件。

　　拆(chai)對分式(shi)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)(luo)釘擰(ning)下(xia)(xia)來(lai)，再輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)器(qi)的(de)一半(ban)從軸(zhou)上慢(man)慢(man)拉下(xia)(xia)，注意不要(yao)掉(diao)了，再用(yong)梅花(hua)扳手(shou)擰(ning)下(xia)(xia)泵(beng)(beng)軸(zhou)吊緊(jin)螺(luo)(luo)栓和(he)擋(dang)塊(kuai)，讓葉(xie)輪慢(man)慢(man)下(xia)(xia)沉(chen)至泵(beng)(beng)體，然后拆(chai)下(xia)(xia)另(ling)外一半(ban)聯(lian)軸(zhou)器(qi)，拿(na)下(xia)(xia)泵(beng)(beng)軸(zhou)擋(dang)圈。

　　拆卸平遠機械密封：抓(zhua)住密封彈(dan)簧順著(zhu)泵(beng)軸往上提，就能拆下(xia)來了。

　　拆(chai)卸(xie)并清洗軸(zhou)(zhou)(zhou)承(cheng)(cheng)座：先輕輕松動一下(xia)軸(zhou)(zhou)(zhou)承(cheng)(cheng)座后用(yong)拆(chai)卸(xie)螺栓頂(ding)起軸(zhou)(zhou)(zhou)承(cheng)(cheng)座，并且沿著泵軸(zhou)(zhou)(zhou)往上提(ti)而卸(xie)下(xia)，再用(yong)噴氣燃(ran)料(liao)清洗軸(zhou)(zhou)(zhou)承(cheng)(cheng)及座，裝(zhuang)前(qian)晾干并涂抹少許20號機械油用(yong)來潤(run)滑保護。

　　拆密封座：擰(ning)下密封座壓緊螺母，輕輕卸下密封座并清洗。

　　平遠機械密封裝(zhuang)配(pei)：在(zai)動(dong)、靜(jing)環(huan)(huan)鏡面(mian)上涂一層潔凈的(de)(de)20號潤滑(hua)(hua)油，導軸(zhou)(zhou)(zhou)承座(zuo)(zuo)也抹(mo)(mo)上潤滑(hua)(hua)油，先(xian)把靜(jing)環(huan)(huan)輕(qing)(qing)輕(qing)(qing)定位裝(zhuang)入導軸(zhou)(zhou)(zhou)承座(zuo)(zuo)，再在(zai)泵(beng)軸(zhou)(zhou)(zhou)上抹(mo)(mo)上潤滑(hua)(hua)油，把動(dong)環(huan)(huan)部分(fen)輕(qing)(qing)輕(qing)(qing)裝(zhuang)入泵(beng)軸(zhou)(zhou)(zhou)上，用手(shou)輕(qing)(qing)推密封環(huan)(huan)應能伸縮自如，注意動(dong)、靜(jing)環(huan)(huan)部分(fen)的(de)(de)防轉部位需(xu)裝(zhuang)配(pei)到位。

　　裝(zhuang)聯(lian)軸(zhou)器(qi)(qi)：在電機軸(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)圈，裝(zhuang)上(shang)(shang)一半聯(lian)軸(zhou)器(qi)(qi)，再在泵軸(zhou)端和聯(lian)軸(zhou)器(qi)(qi)槽內裝(zhuang)上(shang)(shang)擋(dang)塊(kuai)并用梅花(hua)扳手擰緊(jin)螺栓(shuan)；再裝(zhuang)上(shang)(shang)另(ling)一半聯(lian)軸(zhou)器(qi)(qi)擰上(shang)(shang)內六角螺釘。安裝(zhuang)聯(lian)軸(zhou)器(qi)(qi)正(zheng)確的檢查(cha)(cha)要求：對分(fen)式(shi)聯(lian)軸(zhou)器(qi)(qi)上(shang)(shang)下(xia)間隙需要均勻(yun)，用手盤動聯(lian)軸(zhou)器(qi)(qi)幾圈檢查(cha)(cha)轉動的靈活性。

　　裝密(mi)(mi)(mi)封(feng)座(zuo)：先將密(mi)(mi)(mi)封(feng)座(zuo)裝入橡膠油(you)封(feng)，再把(ba)密(mi)(mi)(mi)封(feng)座(zuo)裝入泵蓋(gai)并壓(ya)在軸承座(zuo)上，擰緊螺(luo)母，確保所有(you)安裝螺(luo)釘(ding)(ding)緊固(gu)(gu)。當(dang)安裝螺(luo)釘(ding)(ding)被用(yong)(yong)作密(mi)(mi)(mi)封(feng)與(yu)(yu)軸之(zhi)間(jian)的(de)驅(qu)動時，軸應打埋頭(tou)孔來加(jia)固(gu)(gu)連(lian)接(jie)，緊固(gu)(gu)壓(ya)蓋(gai)螺(luo)栓時應該平穩緊固(gu)(gu)，并且不要使壓(ya)蓋(gai)受彈力。在可能的(de)地方使用(yong)(yong)4個以上螺(luo)釘(ding)(ding)的(de)等間(jian)距壓(ya)蓋(gai)，緊固(gu)(gu)壓(ya)蓋(gai)螺(luo)栓時，用(yong)(yong)塞尺檢查軸與(yu)(yu)壓(ya)蓋(gai)之(zhi)間(jian)的(de)間(jian)隙，這在密(mi)(mi)(mi)封(feng)腔對壓(ya)蓋(gai)不導(dao)向時，顯(xian)得特別重要，因為(wei)壓(ya)蓋(gai)必須(xu)對中。
