疏勒機械密封利(li)用(yong)機械方(fang)式傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力(li)(li)和(he)運動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong),機械傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在機械工(gong)程中(zhong)應(ying)用(yong)非(fei)常廣泛,有(you)多種(zhong)形式,主要包括(kuo)皮帶傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸(gua)(gua)桿(gan)蝸(gua)(gua)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)夠(gou)用(yong)于大功(gong)(gong)率(lv)的(de)場合,傳(chuan)(chuan)動(dong)(dong)(dong)(dong)比準確(que)(que),但一(yi)般(ban)(ban)要求較高的(de)制造(zao)精度和(he)安裝精度。還有(you)一(yi)類是(shi)靠機件(jian)間的(de)摩(mo)(mo)擦力(li)(li)傳(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力(li)(li)和(he)運動(dong)(dong)(dong)(dong)的(de)摩(mo)(mo)擦傳(chuan)(chuan)動(dong)(dong)(dong)(dong),包括(kuo)帶傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)摩(mo)(mo)擦輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。摩(mo)(mo)擦傳(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級變速,可(ke)以適應(ying)軸間距較大的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)場合,而過載打滑還能(neng)起(qi)到緩沖和(he)保護傳(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置的(de)作用(yong),但這種(zhong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)一(yi)般(ban)(ban)不能(neng)用(yong)于大功(gong)(gong)率(lv)的(de)場合,也不能(neng)保證準確(que)(que)的(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)比。
傳動形式多,但是疏勒機械密封的(de)(de)更換工(gong)作大同小異,首先拆前需確認電機處于(yu)檢修狀態,擰下加油螺塞(sai),用吸(xi)管把密封座腔內的(de)(de)潤(run)滑油吸(xi)出。準(zhun)備好放(fang)置泵(beng)零件的(de)(de)工(gong)作臺及拆裝工(gong)具,切(qie)勿任意亂(luan)放(fang)亂(luan)用,避免碰壞泵(beng)的(de)(de)零部件。
拆對分式聯(lian)(lian)軸(zhou)(zhou)器:先(xian)把聯(lian)(lian)軸(zhou)(zhou)器的固定(ding)內六角螺釘擰下來,再(zai)輕輕把聯(lian)(lian)軸(zhou)(zhou)器的一半從軸(zhou)(zhou)上慢(man)慢(man)拉下,注意不要掉了,再(zai)用梅花扳(ban)手擰下泵(beng)(beng)軸(zhou)(zhou)吊緊螺栓和擋(dang)塊,讓葉輪慢(man)慢(man)下沉至泵(beng)(beng)體(ti),然(ran)后拆下另外一半聯(lian)(lian)軸(zhou)(zhou)器,拿(na)下泵(beng)(beng)軸(zhou)(zhou)擋(dang)圈。
拆卸疏勒機械密封:抓住密(mi)封彈(dan)簧(huang)順著(zhu)泵軸往上(shang)提,就能拆(chai)下來了。
拆(chai)卸并清(qing)(qing)洗軸(zhou)(zhou)承座:先輕(qing)輕(qing)松(song)動一下軸(zhou)(zhou)承座后用(yong)拆(chai)卸螺栓頂(ding)起軸(zhou)(zhou)承座,并且沿著泵軸(zhou)(zhou)往上(shang)提而卸下,再(zai)用(yong)噴氣燃料清(qing)(qing)洗軸(zhou)(zhou)承及座,裝前晾干并涂(tu)抹少(shao)許20號(hao)機械油用(yong)來潤滑保護。
拆密(mi)(mi)封(feng)座:擰下密(mi)(mi)封(feng)座壓緊螺(luo)母,輕輕卸下密(mi)(mi)封(feng)座并(bing)清(qing)洗。
疏勒機械密封裝(zhuang)配:在(zai)動、靜環(huan)鏡(jing)面上(shang)(shang)涂一層潔凈的20號潤(run)(run)滑油(you),導(dao)(dao)軸承座也(ye)抹上(shang)(shang)潤(run)(run)滑油(you),先(xian)把(ba)靜環(huan)輕(qing)輕(qing)定位裝(zhuang)入導(dao)(dao)軸承座,再在(zai)泵軸上(shang)(shang)抹上(shang)(shang)潤(run)(run)滑油(you),把(ba)動環(huan)部(bu)(bu)分(fen)輕(qing)輕(qing)裝(zhuang)入泵軸上(shang)(shang),用手(shou)輕(qing)推密封環(huan)應能伸縮自如,注意動、靜環(huan)部(bu)(bu)分(fen)的防(fang)轉部(bu)(bu)位需裝(zhuang)配到位。
裝(zhuang)聯(lian)(lian)(lian)軸(zhou)器(qi):在(zai)電機軸(zhou)頭上裝(zhuang)上擋圈(quan),裝(zhuang)上一半聯(lian)(lian)(lian)軸(zhou)器(qi),再在(zai)泵軸(zhou)端(duan)和聯(lian)(lian)(lian)軸(zhou)器(qi)槽內(nei)裝(zhuang)上擋塊(kuai)并用梅花扳手擰緊(jin)螺栓;再裝(zhuang)上另(ling)一半聯(lian)(lian)(lian)軸(zhou)器(qi)擰上內(nei)六角螺釘。安裝(zhuang)聯(lian)(lian)(lian)軸(zhou)器(qi)正確的檢查要(yao)求:對分式(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)上下間隙需(xu)要(yao)均勻,用手盤(pan)動(dong)(dong)聯(lian)(lian)(lian)軸(zhou)器(qi)幾(ji)圈(quan)檢查轉(zhuan)動(dong)(dong)的靈(ling)活性。
裝(zhuang)密封(feng)座:先將密封(feng)座裝(zhuang)入橡膠油封(feng),再把密封(feng)座裝(zhuang)入泵蓋(gai)(gai)(gai)并壓(ya)在軸承座上(shang),擰緊螺(luo)(luo)母(mu),確保所有安(an)裝(zhuang)螺(luo)(luo)釘緊固(gu)(gu)。當(dang)安(an)裝(zhuang)螺(luo)(luo)釘被(bei)用(yong)(yong)作(zuo)密封(feng)與軸之間(jian)的(de)驅動時,軸應(ying)打埋(mai)頭(tou)孔來加固(gu)(gu)連接,緊固(gu)(gu)壓(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時應(ying)該平(ping)穩緊固(gu)(gu),并且不要使壓(ya)蓋(gai)(gai)(gai)受彈力。在可能的(de)地方使用(yong)(yong)4個(ge)以上(shang)螺(luo)(luo)釘的(de)等間(jian)距壓(ya)蓋(gai)(gai)(gai),緊固(gu)(gu)壓(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時,用(yong)(yong)塞尺檢查軸與壓(ya)蓋(gai)(gai)(gai)之間(jian)的(de)間(jian)隙,這在密封(feng)腔對壓(ya)蓋(gai)(gai)(gai)不導(dao)向時,顯得特別重要,因為壓(ya)蓋(gai)(gai)(gai)必(bi)須對中。
