南通機械密封利用機(ji)(ji)械方式(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)(ji)械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)在機(ji)(ji)械工程中應用非常廣泛(fan)，有(you)多種形式(shi)，主(zhu)要包括皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)能夠(gou)用于大(da)功(gong)率的(de)(de)場(chang)合(he)(he)，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比準確，但(dan)一般要求較高的(de)(de)制造(zao)精度(du)和安裝精度(du)。還有(you)一類是靠機(ji)(ji)件間的(de)(de)摩(mo)擦力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)和運動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)，包括帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)和摩(mo)擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)等(deng)。摩(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級(ji)變(bian)速，可(ke)以適應軸間距(ju)較大(da)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合(he)(he)，而過載(zai)打滑還能起到緩(huan)沖(chong)和保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)作用，但(dan)這(zhe)種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)一般不(bu)能用于大(da)功(gong)率的(de)(de)場(chang)合(he)(he)，也(ye)不(bu)能保證(zheng)準確的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是南通機械密封的更換工(gong)作大同小(xiao)異，首(shou)先拆(chai)前需(xu)確認電(dian)機處于檢(jian)修狀態(tai)，擰下(xia)加油(you)螺塞，用(yong)吸(xi)管把密封(feng)座腔(qiang)內的潤滑(hua)油(you)吸(xi)出。準備好(hao)放置泵零件(jian)的工(gong)作臺及拆(chai)裝工(gong)具，切勿任(ren)意亂(luan)放亂(luan)用(yong)，避免碰壞(huai)泵的零部件(jian)。

　　拆對分式聯軸(zhou)器：先把聯軸(zhou)器的(de)固定內六角螺(luo)釘擰下(xia)來，再(zai)輕輕把聯軸(zhou)器的(de)一半從(cong)軸(zhou)上慢慢拉下(xia)，注意不要(yao)掉(diao)了，再(zai)用梅(mei)花(hua)扳手擰下(xia)泵軸(zhou)吊緊(jin)螺(luo)栓和擋塊，讓葉輪(lun)慢慢下(xia)沉至泵體(ti)，然(ran)后拆下(xia)另外(wai)一半聯軸(zhou)器，拿下(xia)泵軸(zhou)擋圈。

　　拆卸南通機械密封：抓住(zhu)密封(feng)彈簧順著泵軸往上(shang)提，就能拆(chai)下(xia)來了。

　　拆卸并(bing)(bing)清洗軸(zhou)承(cheng)座：先輕輕松動一下軸(zhou)承(cheng)座后用(yong)拆卸螺栓頂起軸(zhou)承(cheng)座，并(bing)(bing)且(qie)沿著泵(beng)軸(zhou)往(wang)上提而卸下，再(zai)用(yong)噴氣燃(ran)料清洗軸(zhou)承(cheng)及座，裝前晾干并(bing)(bing)涂抹少許20號機械油(you)用(yong)來潤滑保護。

　　拆密(mi)封(feng)座(zuo)：擰下密(mi)封(feng)座(zuo)壓(ya)緊螺母，輕輕卸下密(mi)封(feng)座(zuo)并清洗(xi)。

　　南通機械密封裝(zhuang)配(pei)：在動(dong)、靜(jing)環(huan)鏡面(mian)上涂一層潔凈的20號潤(run)滑油(you)(you)，導(dao)軸承(cheng)座也抹上潤(run)滑油(you)(you)，先把(ba)靜(jing)環(huan)輕輕定位裝(zhuang)入導(dao)軸承(cheng)座，再在泵軸上抹上潤(run)滑油(you)(you)，把(ba)動(dong)環(huan)部分(fen)輕輕裝(zhuang)入泵軸上，用手輕推密封(feng)環(huan)應能伸縮自如，注意動(dong)、靜(jing)環(huan)部分(fen)的防轉(zhuan)部位需裝(zhuang)配(pei)到位。

　　裝聯(lian)軸(zhou)(zhou)器(qi)：在(zai)電機軸(zhou)(zhou)頭上(shang)裝上(shang)擋圈，裝上(shang)一(yi)半聯(lian)軸(zhou)(zhou)器(qi)，再在(zai)泵軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)槽內裝上(shang)擋塊(kuai)并用(yong)梅花扳手擰緊螺(luo)栓(shuan)；再裝上(shang)另一(yi)半聯(lian)軸(zhou)(zhou)器(qi)擰上(shang)內六(liu)角(jiao)螺(luo)釘。安裝聯(lian)軸(zhou)(zhou)器(qi)正(zheng)確(que)的(de)檢查(cha)要(yao)求：對分(fen)式聯(lian)軸(zhou)(zhou)器(qi)上(shang)下間(jian)隙需要(yao)均勻，用(yong)手盤動聯(lian)軸(zhou)(zhou)器(qi)幾圈檢查(cha)轉動的(de)靈活性。

　　裝(zhuang)密(mi)封(feng)(feng)(feng)座(zuo)：先將密(mi)封(feng)(feng)(feng)座(zuo)裝(zhuang)入橡膠(jiao)油(you)封(feng)(feng)(feng)，再(zai)把密(mi)封(feng)(feng)(feng)座(zuo)裝(zhuang)入泵蓋(gai)(gai)并壓在軸(zhou)承(cheng)座(zuo)上，擰緊(jin)(jin)螺母，確保所有安裝(zhuang)螺釘(ding)(ding)緊(jin)(jin)固。當安裝(zhuang)螺釘(ding)(ding)被用作密(mi)封(feng)(feng)(feng)與(yu)軸(zhou)之間(jian)的(de)驅動時，軸(zhou)應(ying)打埋頭孔(kong)來加固連(lian)接(jie)，緊(jin)(jin)固壓蓋(gai)(gai)螺栓時應(ying)該平穩緊(jin)(jin)固，并且不(bu)要(yao)使壓蓋(gai)(gai)受彈力。在可能的(de)地方(fang)使用4個以上螺釘(ding)(ding)的(de)等間(jian)距壓蓋(gai)(gai)，緊(jin)(jin)固壓蓋(gai)(gai)螺栓時，用塞尺(chi)檢查軸(zhou)與(yu)壓蓋(gai)(gai)之間(jian)的(de)間(jian)隙，這在密(mi)封(feng)(feng)(feng)腔對壓蓋(gai)(gai)不(bu)導(dao)向時，顯得特別重要(yao)，因為壓蓋(gai)(gai)必須對中。
