劍閣機械密封利用(yong)機(ji)(ji)械方式傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)(ji)械工程(cheng)中應用(yong)非(fei)常廣泛(fan)，有多種形(xing)式，主要包括皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。齒輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)能夠(gou)用(yong)于(yu)大功率(lv)的(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)準(zhun)確(que)，但(dan)一(yi)(yi)(yi)般(ban)要求較(jiao)高(gao)的(de)制造(zao)精度和(he)安裝精度。還(huan)有一(yi)(yi)(yi)類是靠機(ji)(ji)件間(jian)的(de)摩(mo)擦(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、繩(sheng)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)摩(mo)擦(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等(deng)。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)容易(yi)實現無級變速，可以適(shi)應軸(zhou)間(jian)距較(jiao)大的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合，而過載打滑還(huan)能起到緩沖(chong)和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置的(de)作用(yong)，但(dan)這種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)一(yi)(yi)(yi)般(ban)不能用(yong)于(yu)大功率(lv)的(de)場(chang)合，也不能保證準(zhun)確(que)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是劍閣機械密封的更換工作大同小異，首先拆前需確認(ren)電(dian)機處于檢修狀態，擰(ning)下加油(you)螺塞，用(yong)吸管把密封座腔(qiang)內的潤滑油(you)吸出(chu)。準備好(hao)放置泵零件的工作臺及拆裝工具，切勿任意亂放亂用(yong)，避免碰(peng)壞泵的零部件。

　　拆(chai)對(dui)分式聯(lian)軸(zhou)器：先把聯(lian)軸(zhou)器的固定內六角(jiao)螺釘擰下(xia)來，再輕(qing)輕(qing)把聯(lian)軸(zhou)器的一(yi)半從軸(zhou)上慢慢拉下(xia)，注(zhu)意不要掉了，再用梅花(hua)扳手(shou)擰下(xia)泵軸(zhou)吊緊螺栓(shuan)和(he)擋塊，讓葉輪慢慢下(xia)沉至泵體，然后(hou)拆(chai)下(xia)另(ling)外一(yi)半聯(lian)軸(zhou)器，拿下(xia)泵軸(zhou)擋圈。

　　拆卸劍閣機械密封：抓住密封彈(dan)簧順(shun)著泵軸往上(shang)提，就能拆下來了(le)。

　　拆(chai)卸(xie)并清洗軸承座：先(xian)輕輕松動一下(xia)軸承座后用拆(chai)卸(xie)螺(luo)栓頂起軸承座，并且沿著泵軸往(wang)上(shang)提而卸(xie)下(xia)，再用噴氣燃(ran)料清洗軸承及座，裝前晾干并涂抹少許20號機械油用來潤滑保護。

　　拆密封(feng)座(zuo)(zuo)：擰下密封(feng)座(zuo)(zuo)壓緊螺母，輕(qing)(qing)輕(qing)(qing)卸下密封(feng)座(zuo)(zuo)并清洗。

　　劍閣機械密封裝(zhuang)配：在動(dong)、靜環鏡面上(shang)涂一層(ceng)潔(jie)凈(jing)的20號(hao)潤(run)滑油，導(dao)軸(zhou)承(cheng)(cheng)座(zuo)也抹上(shang)潤(run)滑油，先把靜環輕輕定位裝(zhuang)入導(dao)軸(zhou)承(cheng)(cheng)座(zuo)，再(zai)在泵軸(zhou)上(shang)抹上(shang)潤(run)滑油，把動(dong)環部(bu)分輕輕裝(zhuang)入泵軸(zhou)上(shang)，用(yong)手輕推密封環應能(neng)伸縮自如，注意動(dong)、靜環部(bu)分的防轉部(bu)位需裝(zhuang)配到(dao)位。

　　裝(zhuang)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)：在(zai)電(dian)機軸(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋(dang)圈，裝(zhuang)上(shang)一半聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)，再在(zai)泵軸(zhou)(zhou)端和聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)槽內裝(zhuang)上(shang)擋(dang)塊(kuai)并用梅花扳手擰緊螺栓；再裝(zhuang)上(shang)另一半聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)擰上(shang)內六角(jiao)螺釘。安裝(zhuang)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)正確的檢(jian)查要(yao)求：對分式聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)上(shang)下間隙需(xu)要(yao)均勻，用手盤動聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)(qi)幾圈檢(jian)查轉動的靈活性。

　　裝密(mi)封(feng)(feng)座(zuo)：先將(jiang)密(mi)封(feng)(feng)座(zuo)裝入(ru)橡膠油封(feng)(feng)，再把密(mi)封(feng)(feng)座(zuo)裝入(ru)泵蓋并壓在軸(zhou)承(cheng)座(zuo)上，擰緊(jin)螺(luo)(luo)母(mu)，確保所有安(an)裝螺(luo)(luo)釘緊(jin)固(gu)。當安(an)裝螺(luo)(luo)釘被(bei)用作密(mi)封(feng)(feng)與軸(zhou)之(zhi)間的驅動時，軸(zhou)應(ying)(ying)打埋頭孔來加固(gu)連接，緊(jin)固(gu)壓蓋螺(luo)(luo)栓時應(ying)(ying)該(gai)平穩緊(jin)固(gu)，并且不要使(shi)(shi)壓蓋受彈(dan)力。在可(ke)能的地方(fang)使(shi)(shi)用4個以(yi)上螺(luo)(luo)釘的等間距壓蓋，緊(jin)固(gu)壓蓋螺(luo)(luo)栓時，用塞尺檢(jian)查軸(zhou)與壓蓋之(zhi)間的間隙，這在密(mi)封(feng)(feng)腔對壓蓋不導向時，顯得特別重要，因(yin)為壓蓋必須(xu)對中。
