西陵機械密封利用(yong)(yong)機械(xie)方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong),機械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)在(zai)機械(xie)工程中應用(yong)(yong)非常廣泛(fan),有(you)(you)多種形式,主要包括皮(pi)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪(lun)(lun)齒(chi)(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)(he)螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)能(neng)(neng)夠(gou)用(yong)(yong)于(yu)大功率(lv)的(de)(de)(de)場(chang)合,傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)比準(zhun)(zhun)確,但一(yi)般要求較高(gao)的(de)(de)(de)制造精度(du)和(he)(he)安裝精度(du)。還有(you)(you)一(yi)類是靠機件(jian)間的(de)(de)(de)摩(mo)擦(ca)(ca)力傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)的(de)(de)(de)摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong),包括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)(ca)輪(lun)(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。摩(mo)擦(ca)(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易實(shi)現無級變速,可(ke)以(yi)適應軸間距較大的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)場(chang)合,而過載(zai)打滑還能(neng)(neng)起(qi)到緩沖和(he)(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝置的(de)(de)(de)作用(yong)(yong),但這(zhe)種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)一(yi)般不(bu)能(neng)(neng)用(yong)(yong)于(yu)大功率(lv)的(de)(de)(de)場(chang)合,也(ye)不(bu)能(neng)(neng)保證(zheng)準(zhun)(zhun)確的(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)比。
傳動形式多,但是西陵機械密封的(de)更(geng)換(huan)工(gong)(gong)作大同小異,首先拆前需確認電機處于(yu)檢修狀(zhuang)態(tai),擰(ning)下(xia)加油螺塞,用吸(xi)管把密封座腔內的(de)潤滑(hua)油吸(xi)出。準備好(hao)放(fang)置泵(beng)零件的(de)工(gong)(gong)作臺及拆裝工(gong)(gong)具,切勿任意亂放(fang)亂用,避免碰壞泵(beng)的(de)零部件。
拆對分(fen)式聯(lian)軸(zhou)(zhou)器(qi)(qi):先把聯(lian)軸(zhou)(zhou)器(qi)(qi)的固定內(nei)六(liu)角螺釘擰下(xia)來,再輕輕把聯(lian)軸(zhou)(zhou)器(qi)(qi)的一(yi)半(ban)從軸(zhou)(zhou)上慢慢拉下(xia),注意不要(yao)掉了(le),再用梅花扳手擰下(xia)泵(beng)軸(zhou)(zhou)吊緊螺栓和擋塊,讓葉輪慢慢下(xia)沉至泵(beng)體(ti),然后(hou)拆下(xia)另(ling)外一(yi)半(ban)聯(lian)軸(zhou)(zhou)器(qi)(qi),拿下(xia)泵(beng)軸(zhou)(zhou)擋圈。
拆卸西陵機械密封:抓住密封彈簧順著泵(beng)軸往上提,就能拆下來了。
拆卸并(bing)清(qing)洗(xi)(xi)軸承(cheng)座(zuo)(zuo):先輕輕松動一下(xia)軸承(cheng)座(zuo)(zuo)后用拆卸螺栓(shuan)頂起軸承(cheng)座(zuo)(zuo),并(bing)且(qie)沿(yan)著泵軸往上提(ti)而卸下(xia),再用噴氣燃料清(qing)洗(xi)(xi)軸承(cheng)及(ji)座(zuo)(zuo),裝前晾干并(bing)涂抹少許20號機械油(you)用來潤滑(hua)保護。
拆密(mi)封(feng)座:擰下密(mi)封(feng)座壓緊螺母,輕(qing)輕(qing)卸下密(mi)封(feng)座并清洗。
西陵機械密封裝(zhuang)配:在動(dong)、靜(jing)環(huan)鏡面上涂一層潔凈的20號潤滑(hua)油(you),導(dao)軸(zhou)承座也抹(mo)上潤滑(hua)油(you),先把靜(jing)環(huan)輕(qing)輕(qing)定位裝(zhuang)入導(dao)軸(zhou)承座,再(zai)在泵軸(zhou)上抹(mo)上潤滑(hua)油(you),把動(dong)環(huan)部分輕(qing)輕(qing)裝(zhuang)入泵軸(zhou)上,用(yong)手輕(qing)推密封環(huan)應能伸縮自如(ru),注意動(dong)、靜(jing)環(huan)部分的防轉(zhuan)部位需裝(zhuang)配到位。
裝(zhuang)(zhuang)(zhuang)聯軸(zhou)(zhou)器(qi):在(zai)電機(ji)軸(zhou)(zhou)頭上裝(zhuang)(zhuang)(zhuang)上擋圈,裝(zhuang)(zhuang)(zhuang)上一半聯軸(zhou)(zhou)器(qi),再(zai)在(zai)泵軸(zhou)(zhou)端(duan)和聯軸(zhou)(zhou)器(qi)槽內(nei)裝(zhuang)(zhuang)(zhuang)上擋塊并用(yong)梅花扳(ban)手(shou)擰(ning)緊螺栓;再(zai)裝(zhuang)(zhuang)(zhuang)上另(ling)一半聯軸(zhou)(zhou)器(qi)擰(ning)上內(nei)六角(jiao)螺釘。安裝(zhuang)(zhuang)(zhuang)聯軸(zhou)(zhou)器(qi)正確的檢查要求(qiu):對(dui)分式聯軸(zhou)(zhou)器(qi)上下(xia)間隙需要均勻,用(yong)手(shou)盤動聯軸(zhou)(zhou)器(qi)幾圈檢查轉動的靈活(huo)性。
裝密(mi)(mi)封座:先(xian)將(jiang)密(mi)(mi)封座裝入橡膠油封,再把密(mi)(mi)封座裝入泵(beng)蓋(gai)(gai)(gai)并(bing)壓(ya)(ya)在(zai)軸(zhou)承座上(shang),擰(ning)緊螺(luo)(luo)母,確(que)保所有(you)安裝螺(luo)(luo)釘緊固(gu)(gu)。當(dang)安裝螺(luo)(luo)釘被用作(zuo)密(mi)(mi)封與軸(zhou)之(zhi)(zhi)間(jian)的驅動(dong)時(shi),軸(zhou)應打埋頭孔來(lai)加(jia)固(gu)(gu)連接,緊固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi)應該平穩緊固(gu)(gu),并(bing)且(qie)不(bu)要使(shi)壓(ya)(ya)蓋(gai)(gai)(gai)受(shou)彈(dan)力。在(zai)可能的地方使(shi)用4個以(yi)上(shang)螺(luo)(luo)釘的等間(jian)距(ju)壓(ya)(ya)蓋(gai)(gai)(gai),緊固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi),用塞尺(chi)檢查軸(zhou)與壓(ya)(ya)蓋(gai)(gai)(gai)之(zhi)(zhi)間(jian)的間(jian)隙,這在(zai)密(mi)(mi)封腔對壓(ya)(ya)蓋(gai)(gai)(gai)不(bu)導向時(shi),顯得特別重要,因為壓(ya)(ya)蓋(gai)(gai)(gai)必須對中(zhong)。
