  高唐機械密封利用機(ji)械(xie)方式傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和運(yun)動(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong),機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機(ji)械(xie)工程中應(ying)用非常廣泛,有(you)多種形式,主要包括(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)能(neng)(neng)夠用于大功(gong)率的(de)(de)場合,傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)準確,但(dan)一(yi)般(ban)要求較高的(de)(de)制造精度和安裝精度。還(huan)有(you)一(yi)類是靠機(ji)件間的(de)(de)摩(mo)(mo)擦力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和運(yun)動(dong)(dong)(dong)的(de)(de)摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong),包括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)和摩(mo)(mo)擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易(yi)實現(xian)無級變速,可以(yi)適應(ying)軸(zhou)間距較大的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)場合,而過載打滑還(huan)能(neng)(neng)起到(dao)緩沖和保(bao)護傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝置(zhi)的(de)(de)作(zuo)用,但(dan)這種傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)一(yi)般(ban)不(bu)(bu)能(neng)(neng)用于大功(gong)率的(de)(de)場合,也不(bu)(bu)能(neng)(neng)保(bao)證準確的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)。

  傳動形式多,但是高唐機械密封的(de)更換工作(zuo)大(da)同小異,首先拆前需確認電機處于檢修狀態,擰(ning)下加油(you)螺塞(sai),用吸管(guan)把密封座腔內的(de)潤(run)滑油(you)吸出。準備(bei)好放(fang)置(zhi)泵零(ling)件的(de)工作(zuo)臺及拆裝工具,切勿任意(yi)亂放(fang)亂用,避(bi)免碰壞泵的(de)零(ling)部件。

  拆對分(fen)式(shi)聯(lian)(lian)軸(zhou)器(qi)(qi)(qi):先把聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)的固(gu)定內六角螺(luo)釘擰(ning)下(xia)(xia)(xia)(xia)來,再輕輕把聯(lian)(lian)軸(zhou)器(qi)(qi)(qi)的一半從軸(zhou)上慢(man)慢(man)拉下(xia)(xia)(xia)(xia),注意不要掉了,再用(yong)梅花(hua)扳手擰(ning)下(xia)(xia)(xia)(xia)泵軸(zhou)吊緊螺(luo)栓和(he)擋塊,讓葉輪慢(man)慢(man)下(xia)(xia)(xia)(xia)沉(chen)至泵體,然后(hou)拆下(xia)(xia)(xia)(xia)另外一半聯(lian)(lian)軸(zhou)器(qi)(qi)(qi),拿下(xia)(xia)(xia)(xia)泵軸(zhou)擋圈。

  拆卸高唐機械密封:抓住密封(feng)彈簧順(shun)著泵軸往上提,就能拆下來(lai)了。

  拆卸(xie)(xie)并清洗軸(zhou)(zhou)承座(zuo):先輕輕松動一下軸(zhou)(zhou)承座(zuo)后用(yong)拆卸(xie)(xie)螺栓(shuan)頂起(qi)軸(zhou)(zhou)承座(zuo),并且沿(yan)著泵軸(zhou)(zhou)往(wang)上提而卸(xie)(xie)下,再用(yong)噴氣(qi)燃料清洗軸(zhou)(zhou)承及座(zuo),裝前晾(liang)干并涂抹少(shao)許20號機械油(you)用(yong)來潤滑保(bao)護。

  拆(chai)密(mi)封(feng)座:擰(ning)下密(mi)封(feng)座壓緊螺母,輕輕卸下密(mi)封(feng)座并(bing)清洗。

  高唐機械密封裝(zhuang)配:在動、靜環(huan)鏡(jing)面(mian)上(shang)涂一層(ceng)潔凈的(de)20號(hao)潤(run)滑(hua)油(you),導軸承座也抹(mo)上(shang)潤(run)滑(hua)油(you),先把靜環(huan)輕輕定位(wei)裝(zhuang)入導軸承座,再在泵軸上(shang)抹(mo)上(shang)潤(run)滑(hua)油(you),把動環(huan)部(bu)分輕輕裝(zhuang)入泵軸上(shang),用手輕推密封環(huan)應能伸縮自如,注意動、靜環(huan)部(bu)分的(de)防轉部(bu)位(wei)需裝(zhuang)配到位(wei)。

  裝(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)(qi):在電機軸(zhou)頭(tou)上裝(zhuang)(zhuang)上擋(dang)圈,裝(zhuang)(zhuang)上一(yi)半聯(lian)軸(zhou)器(qi)(qi),再(zai)在泵軸(zhou)端和(he)聯(lian)軸(zhou)器(qi)(qi)槽內(nei)裝(zhuang)(zhuang)上擋(dang)塊并(bing)用梅花扳手擰緊螺栓;再(zai)裝(zhuang)(zhuang)上另(ling)一(yi)半聯(lian)軸(zhou)器(qi)(qi)擰上內(nei)六角螺釘。安裝(zhuang)(zhuang)聯(lian)軸(zhou)器(qi)(qi)正確(que)的檢(jian)(jian)查要求:對(dui)分式聯(lian)軸(zhou)器(qi)(qi)上下間(jian)隙需要均(jun)勻,用手盤動聯(lian)軸(zhou)器(qi)(qi)幾圈檢(jian)(jian)查轉動的靈(ling)活性(xing)。

  裝(zhuang)(zhuang)(zhuang)密(mi)封(feng)座:先將密(mi)封(feng)座裝(zhuang)(zhuang)(zhuang)入(ru)橡膠油(you)封(feng),再把密(mi)封(feng)座裝(zhuang)(zhuang)(zhuang)入(ru)泵蓋(gai)并(bing)壓(ya)在(zai)軸承座上(shang),擰緊螺(luo)(luo)母,確保所有安裝(zhuang)(zhuang)(zhuang)螺(luo)(luo)釘緊固。當安裝(zhuang)(zhuang)(zhuang)螺(luo)(luo)釘被用作(zuo)密(mi)封(feng)與軸之間的(de)驅動時(shi)(shi),軸應(ying)打(da)埋(mai)頭孔來加固連接,緊固壓(ya)蓋(gai)螺(luo)(luo)栓時(shi)(shi)應(ying)該平(ping)穩(wen)緊固,并(bing)且不要(yao)使壓(ya)蓋(gai)受(shou)彈力。在(zai)可(ke)能的(de)地方使用4個以上(shang)螺(luo)(luo)釘的(de)等間距壓(ya)蓋(gai),緊固壓(ya)蓋(gai)螺(luo)(luo)栓時(shi)(shi),用塞尺檢查軸與壓(ya)蓋(gai)之間的(de)間隙(xi),這在(zai)密(mi)封(feng)腔對壓(ya)蓋(gai)不導(dao)向時(shi)(shi),顯得(de)特(te)別重要(yao),因為壓(ya)蓋(gai)必(bi)須(xu)對中。
