錫林郭勒如何對機械密封進行更換工作

發布(bu)時間:2021-12-17 11:49:09 人氣:98933 來(lai)源:

  錫林郭勒機械密封利用(yong)機械(xie)方式(shi)傳(chuan)(chuan)(chuan)遞動(dong)(dong)力(li)和運動(dong)(dong)的(de)(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong),機械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)在機械(xie)工(gong)程(cheng)中應(ying)用(yong)非(fei)常廣泛(fan),有多種(zhong)形式(shi),主要包(bao)(bao)括(kuo)皮帶(dai)(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)動(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)動(dong)(dong)等。齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)能(neng)夠(gou)用(yong)于(yu)大(da)(da)(da)功(gong)(gong)率的(de)(de)(de)(de)(de)場(chang)合,傳(chuan)(chuan)(chuan)動(dong)(dong)比準確(que),但一般(ban)要求較高(gao)的(de)(de)(de)(de)(de)制(zhi)造精度和安裝精度。還有一類是(shi)靠機件間的(de)(de)(de)(de)(de)摩(mo)擦(ca)力(li)傳(chuan)(chuan)(chuan)遞動(dong)(dong)力(li)和運動(dong)(dong)的(de)(de)(de)(de)(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong),包(bao)(bao)括(kuo)帶(dai)(dai)傳(chuan)(chuan)(chuan)動(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)和摩(mo)擦(ca)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)容易實現(xian)無級變速(su),可(ke)以適應(ying)軸間距較大(da)(da)(da)的(de)(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)場(chang)合,而過載(zai)打滑還能(neng)起到緩(huan)沖和保護傳(chuan)(chuan)(chuan)動(dong)(dong)裝置(zhi)的(de)(de)(de)(de)(de)作用(yong),但這種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)一般(ban)不(bu)(bu)能(neng)用(yong)于(yu)大(da)(da)(da)功(gong)(gong)率的(de)(de)(de)(de)(de)場(chang)合,也不(bu)(bu)能(neng)保證準確(que)的(de)(de)(de)(de)(de)傳(chuan)(chuan)(chuan)動(dong)(dong)比。


  傳動形式多,但是錫林郭勒機械密封的(de)(de)更(geng)換(huan)工作(zuo)大同小(xiao)異,首先拆前需確認(ren)電(dian)機處于(yu)檢修狀態,擰(ning)下加油螺塞,用(yong)吸管把密封座腔(qiang)內的(de)(de)潤滑油吸出。準(zhun)備好放(fang)置泵零件的(de)(de)工作(zuo)臺及拆裝工具,切(qie)勿任意(yi)亂放(fang)亂用(yong),避免(mian)碰壞泵的(de)(de)零部件。


  拆對分式聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi):先把聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的固定內六角螺(luo)釘擰下(xia)來,再輕(qing)輕(qing)把聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的一(yi)半從軸(zhou)(zhou)(zhou)上慢慢拉下(xia),注意不要(yao)掉了,再用梅花扳手擰下(xia)泵軸(zhou)(zhou)(zhou)吊(diao)緊螺(luo)栓和擋塊,讓葉輪慢慢下(xia)沉至(zhi)泵體,然后拆下(xia)另外一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi),拿下(xia)泵軸(zhou)(zhou)(zhou)擋圈。

  拆卸錫林郭勒機械密封:抓住密封(feng)彈簧順著泵軸往上提,就能拆下來了(le)。


  拆(chai)卸并清洗軸承座:先(xian)輕輕松動(dong)一下(xia)軸承座后用(yong)拆(chai)卸螺(luo)栓頂起軸承座,并且沿著泵軸往上提而卸下(xia),再(zai)用(yong)噴(pen)氣燃料(liao)清洗軸承及座,裝前晾干并涂抹少許(xu)20號(hao)機(ji)械(xie)油用(yong)來潤滑(hua)保護。


  拆密(mi)封(feng)座:擰下(xia)密(mi)封(feng)座壓緊螺(luo)母,輕輕卸下(xia)密(mi)封(feng)座并清洗(xi)。


  錫林郭勒機械密封裝(zhuang)(zhuang)配(pei):在動、靜環(huan)鏡面上涂一層潔凈的(de)20號(hao)潤(run)滑(hua)油(you),導軸承座(zuo)也(ye)抹(mo)上潤(run)滑(hua)油(you),先(xian)把靜環(huan)輕(qing)(qing)(qing)輕(qing)(qing)(qing)定位裝(zhuang)(zhuang)入導軸承座(zuo),再在泵(beng)軸上抹(mo)上潤(run)滑(hua)油(you),把動環(huan)部(bu)分(fen)輕(qing)(qing)(qing)輕(qing)(qing)(qing)裝(zhuang)(zhuang)入泵(beng)軸上,用手輕(qing)(qing)(qing)推(tui)密封環(huan)應能伸縮自如,注意(yi)動、靜環(huan)部(bu)分(fen)的(de)防轉部(bu)位需裝(zhuang)(zhuang)配(pei)到位。


  裝(zhuang)聯(lian)軸器(qi):在電機軸頭上(shang)裝(zhuang)上(shang)擋(dang)(dang)圈,裝(zhuang)上(shang)一(yi)半聯(lian)軸器(qi),再在泵軸端和聯(lian)軸器(qi)槽內裝(zhuang)上(shang)擋(dang)(dang)塊并用梅花扳手(shou)擰緊(jin)螺(luo)栓;再裝(zhuang)上(shang)另一(yi)半聯(lian)軸器(qi)擰上(shang)內六角螺(luo)釘。安(an)裝(zhuang)聯(lian)軸器(qi)正確(que)的檢查要求:對(dui)分式(shi)聯(lian)軸器(qi)上(shang)下間隙(xi)需要均勻,用手(shou)盤動(dong)聯(lian)軸器(qi)幾圈檢查轉動(dong)的靈活性。


  裝密(mi)封(feng)(feng)座(zuo):先將密(mi)封(feng)(feng)座(zuo)裝入橡膠油封(feng)(feng),再把密(mi)封(feng)(feng)座(zuo)裝入泵蓋并(bing)壓(ya)(ya)(ya)(ya)(ya)在(zai)軸(zhou)承座(zuo)上,擰緊(jin)(jin)(jin)螺(luo)母,確保所有安裝螺(luo)釘緊(jin)(jin)(jin)固。當安裝螺(luo)釘被用作密(mi)封(feng)(feng)與(yu)軸(zhou)之(zhi)(zhi)間(jian)(jian)的驅動(dong)時,軸(zhou)應(ying)打埋頭孔(kong)來加固連接,緊(jin)(jin)(jin)固壓(ya)(ya)(ya)(ya)(ya)蓋螺(luo)栓(shuan)(shuan)時應(ying)該平穩緊(jin)(jin)(jin)固,并(bing)且不(bu)要使壓(ya)(ya)(ya)(ya)(ya)蓋受彈力。在(zai)可能的地(di)方使用4個以(yi)上螺(luo)釘的等間(jian)(jian)距(ju)壓(ya)(ya)(ya)(ya)(ya)蓋,緊(jin)(jin)(jin)固壓(ya)(ya)(ya)(ya)(ya)蓋螺(luo)栓(shuan)(shuan)時,用塞(sai)尺檢查軸(zhou)與(yu)壓(ya)(ya)(ya)(ya)(ya)蓋之(zhi)(zhi)間(jian)(jian)的間(jian)(jian)隙,這在(zai)密(mi)封(feng)(feng)腔對壓(ya)(ya)(ya)(ya)(ya)蓋不(bu)導向時,顯得特別重要,因為壓(ya)(ya)(ya)(ya)(ya)蓋必須對中(zhong)。
