鳳翔機械密封利用(yong)(yong)機械方(fang)式(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力和(he)(he)運動(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong),機械傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)在機械工(gong)程中(zhong)應用(yong)(yong)非(fei)常廣泛,有多種形式(shi),主要(yao)包(bao)括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒輪(lun)(lun)(lun)齒條傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和(he)(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等。齒輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)能(neng)夠用(yong)(yong)于(yu)大(da)功(gong)率的(de)場(chang)(chang)合(he),傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比準確,但(dan)一(yi)般(ban)要(yao)求較高(gao)的(de)制造精(jing)度和(he)(he)安裝精(jing)度。還有一(yi)類是(shi)靠機件間的(de)摩(mo)(mo)擦(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力和(he)(he)運動(dong)(dong)的(de)摩(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong),包(bao)括帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和(he)(he)摩(mo)(mo)擦(ca)輪(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等。摩(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)容易實現無級變速,可以適應軸間距較大(da)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)場(chang)(chang)合(he),而過載打滑還能(neng)起到緩沖和(he)(he)保護(hu)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)裝置的(de)作用(yong)(yong),但(dan)這(zhe)種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)一(yi)般(ban)不(bu)能(neng)用(yong)(yong)于(yu)大(da)功(gong)率的(de)場(chang)(chang)合(he),也(ye)不(bu)能(neng)保證準確的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比。
傳動形式多,但是鳳翔機械密封的更換工作大(da)同小(xiao)異,首先(xian)拆前需確認電機處于檢修狀態(tai),擰下加油螺塞,用吸(xi)管把密(mi)封座腔內的潤滑油吸(xi)出。準備好放(fang)置泵零件的工作臺及拆裝工具(ju),切(qie)勿任意亂(luan)放(fang)亂(luan)用,避免碰壞泵的零部件。
拆對分式聯(lian)軸(zhou)器(qi):先(xian)把聯(lian)軸(zhou)器(qi)的固定(ding)內(nei)六角螺(luo)釘(ding)擰下來(lai),再輕輕把聯(lian)軸(zhou)器(qi)的一半從軸(zhou)上慢慢拉下,注意(yi)不要掉了,再用梅花扳手擰下泵軸(zhou)吊緊(jin)螺(luo)栓和擋塊(kuai),讓葉輪(lun)慢慢下沉至泵體,然(ran)后拆下另外一半聯(lian)軸(zhou)器(qi),拿下泵軸(zhou)擋圈。
拆卸鳳翔機械密封:抓(zhua)住密封彈簧順著泵軸往(wang)上提,就(jiu)能(neng)拆下來了。
拆卸并(bing)(bing)清洗軸承座(zuo):先輕(qing)輕(qing)松(song)動一下軸承座(zuo)后用(yong)拆卸螺栓頂起(qi)軸承座(zuo),并(bing)(bing)且(qie)沿著泵(beng)軸往(wang)上提而卸下,再(zai)用(yong)噴氣燃(ran)料(liao)清洗軸承及(ji)座(zuo),裝前晾(liang)干并(bing)(bing)涂抹少(shao)許20號機械油用(yong)來(lai)潤滑保護。
拆密封(feng)座:擰下密封(feng)座壓緊螺母(mu),輕(qing)輕(qing)卸下密封(feng)座并(bing)清洗。
鳳翔機械密封裝(zhuang)(zhuang)(zhuang)配:在動(dong)、靜(jing)環鏡面上(shang)涂一層(ceng)潔凈(jing)的20號潤滑(hua)油,導軸承座也(ye)抹(mo)上(shang)潤滑(hua)油,先(xian)把靜(jing)環輕(qing)輕(qing)定位(wei)裝(zhuang)(zhuang)(zhuang)入導軸承座,再在泵軸上(shang)抹(mo)上(shang)潤滑(hua)油,把動(dong)環部分輕(qing)輕(qing)裝(zhuang)(zhuang)(zhuang)入泵軸上(shang),用手輕(qing)推密封環應(ying)能伸縮(suo)自(zi)如,注(zhu)意動(dong)、靜(jing)環部分的防轉部位(wei)需裝(zhuang)(zhuang)(zhuang)配到位(wei)。
裝聯(lian)軸(zhou)(zhou)(zhou)器(qi):在(zai)電機軸(zhou)(zhou)(zhou)頭(tou)上(shang)(shang)裝上(shang)(shang)擋圈,裝上(shang)(shang)一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器(qi),再在(zai)泵軸(zhou)(zhou)(zhou)端(duan)和聯(lian)軸(zhou)(zhou)(zhou)器(qi)槽(cao)內裝上(shang)(shang)擋塊并用梅花扳手(shou)擰緊螺栓;再裝上(shang)(shang)另一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器(qi)擰上(shang)(shang)內六角螺釘。安裝聯(lian)軸(zhou)(zhou)(zhou)器(qi)正確的(de)檢(jian)查(cha)要求:對分式聯(lian)軸(zhou)(zhou)(zhou)器(qi)上(shang)(shang)下間(jian)隙需要均勻,用手(shou)盤(pan)動聯(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈檢(jian)查(cha)轉動的(de)靈活性。
裝密封座(zuo):先(xian)將密封座(zuo)裝入橡膠油(you)封,再(zai)把密封座(zuo)裝入泵蓋(gai)(gai)并壓(ya)在軸承座(zuo)上,擰(ning)緊螺(luo)母,確保所有安(an)裝螺(luo)釘(ding)緊固(gu)。當安(an)裝螺(luo)釘(ding)被用作密封與(yu)(yu)軸之間的(de)(de)驅動時(shi)(shi),軸應(ying)打埋頭孔來加固(gu)連(lian)接,緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)(shi)應(ying)該平(ping)穩緊固(gu),并且不要使(shi)壓(ya)蓋(gai)(gai)受彈力(li)。在可(ke)能的(de)(de)地方使(shi)用4個以上螺(luo)釘(ding)的(de)(de)等間距壓(ya)蓋(gai)(gai),緊固(gu)壓(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)(shi),用塞尺檢查軸與(yu)(yu)壓(ya)蓋(gai)(gai)之間的(de)(de)間隙,這(zhe)在密封腔對壓(ya)蓋(gai)(gai)不導向時(shi)(shi),顯得(de)特別重要,因為壓(ya)蓋(gai)(gai)必須(xu)對中。
