沅陵機械密封利(li)用(yong)機械方式(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機械工(gong)程中應用(yong)非常廣泛(fan)，有多種形式(shi)，主要(yao)包(bao)括(kuo)(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。齒(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)能夠用(yong)于(yu)大功率的場合(he)(he)，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比準確(que)，但一(yi)般(ban)要(yao)求較高的制造精度和(he)安裝精度。還有一(yi)類是靠機件間的摩(mo)擦力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)的摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，包(bao)括(kuo)(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)摩(mo)擦輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易實現無級變(bian)速(su)，可以適應軸間距較大的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)場合(he)(he)，而過載(zai)打滑還能起到緩沖和(he)保(bao)護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝置(zhi)的作用(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)一(yi)般(ban)不能用(yong)于(yu)大功率的場合(he)(he)，也不能保(bao)證準確(que)的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比。

　　傳動形式多，但是沅陵機械密封的更換工(gong)作(zuo)大同小異，首先拆前需確認電(dian)機處(chu)于檢(jian)修狀態，擰下(xia)加油螺(luo)塞，用吸管把密封座腔內的潤滑油吸出。準備好(hao)放置泵零件的工(gong)作(zuo)臺及(ji)拆裝(zhuang)工(gong)具，切勿任(ren)意亂放亂用，避免碰(peng)壞(huai)泵的零部件。

　　拆對分式(shi)聯軸(zhou)器(qi)(qi)：先(xian)把(ba)聯軸(zhou)器(qi)(qi)的固定內六角螺釘擰下(xia)來，再(zai)輕(qing)輕(qing)把(ba)聯軸(zhou)器(qi)(qi)的一半(ban)從(cong)軸(zhou)上慢(man)慢(man)拉下(xia)，注意(yi)不要掉了(le)，再(zai)用(yong)梅花扳手擰下(xia)泵(beng)(beng)軸(zhou)吊(diao)緊螺栓和擋(dang)塊，讓葉輪(lun)慢(man)慢(man)下(xia)沉至泵(beng)(beng)體，然后拆下(xia)另外一半(ban)聯軸(zhou)器(qi)(qi)，拿下(xia)泵(beng)(beng)軸(zhou)擋(dang)圈(quan)。

　　拆卸沅陵機械密封：抓住(zhu)密封彈簧順著(zhu)泵軸往上提，就能拆(chai)下來了。

　　拆卸并清(qing)洗軸(zhou)(zhou)承(cheng)座：先輕(qing)(qing)輕(qing)(qing)松動一下(xia)軸(zhou)(zhou)承(cheng)座后用拆卸螺栓頂起軸(zhou)(zhou)承(cheng)座，并且沿著泵軸(zhou)(zhou)往上(shang)提(ti)而卸下(xia)，再用噴氣燃料清(qing)洗軸(zhou)(zhou)承(cheng)及座，裝前晾干(gan)并涂抹(mo)少許20號機械油用來潤滑(hua)保護(hu)。

　　拆密(mi)(mi)封座(zuo)：擰下密(mi)(mi)封座(zuo)壓緊螺(luo)母，輕輕卸下密(mi)(mi)封座(zuo)并(bing)清洗(xi)。

　　沅陵機械密封裝(zhuang)配(pei)：在動(dong)、靜環(huan)鏡面上涂一層潔凈的20號潤滑(hua)油，導軸(zhou)(zhou)承(cheng)座也抹上潤滑(hua)油，先把(ba)靜環(huan)輕輕定位(wei)裝(zhuang)入導軸(zhou)(zhou)承(cheng)座，再在泵軸(zhou)(zhou)上抹上潤滑(hua)油，把(ba)動(dong)環(huan)部(bu)分輕輕裝(zhuang)入泵軸(zhou)(zhou)上，用手輕推密封環(huan)應(ying)能(neng)伸縮自如，注意動(dong)、靜環(huan)部(bu)分的防轉(zhuan)部(bu)位(wei)需裝(zhuang)配(pei)到位(wei)。

　　裝(zhuang)(zhuang)聯(lian)(lian)軸器(qi)(qi)：在電機軸頭上(shang)(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)(shang)擋圈，裝(zhuang)(zhuang)上(shang)(shang)(shang)一(yi)半聯(lian)(lian)軸器(qi)(qi)，再在泵軸端(duan)和聯(lian)(lian)軸器(qi)(qi)槽(cao)內(nei)裝(zhuang)(zhuang)上(shang)(shang)(shang)擋塊并用梅花扳手(shou)擰(ning)緊螺栓；再裝(zhuang)(zhuang)上(shang)(shang)(shang)另一(yi)半聯(lian)(lian)軸器(qi)(qi)擰(ning)上(shang)(shang)(shang)內(nei)六角螺釘。安裝(zhuang)(zhuang)聯(lian)(lian)軸器(qi)(qi)正確(que)的(de)檢查(cha)要(yao)求(qiu)：對分式聯(lian)(lian)軸器(qi)(qi)上(shang)(shang)(shang)下間隙需(xu)要(yao)均勻(yun)，用手(shou)盤動(dong)聯(lian)(lian)軸器(qi)(qi)幾圈檢查(cha)轉動(dong)的(de)靈活(huo)性。

　　裝(zhuang)(zhuang)密(mi)封(feng)座(zuo)：先將密(mi)封(feng)座(zuo)裝(zhuang)(zhuang)入橡膠(jiao)油封(feng)，再(zai)把密(mi)封(feng)座(zuo)裝(zhuang)(zhuang)入泵蓋(gai)并壓在(zai)(zai)軸(zhou)承座(zuo)上(shang)，擰緊(jin)螺母，確保所有安(an)裝(zhuang)(zhuang)螺釘緊(jin)固。當安(an)裝(zhuang)(zhuang)螺釘被用作密(mi)封(feng)與(yu)軸(zhou)之(zhi)(zhi)間的(de)驅動時(shi)，軸(zhou)應打埋(mai)頭孔來加固連接，緊(jin)固壓蓋(gai)螺栓(shuan)時(shi)應該(gai)平穩緊(jin)固，并且不要使壓蓋(gai)受彈力。在(zai)(zai)可能(neng)的(de)地(di)方(fang)使用4個以上(shang)螺釘的(de)等(deng)間距壓蓋(gai)，緊(jin)固壓蓋(gai)螺栓(shuan)時(shi)，用塞尺檢查軸(zhou)與(yu)壓蓋(gai)之(zhi)(zhi)間的(de)間隙，這在(zai)(zai)密(mi)封(feng)腔(qiang)對(dui)壓蓋(gai)不導(dao)向時(shi)，顯得特別重要，因為壓蓋(gai)必(bi)須對(dui)中。
