南坤鎮機械密封利用(yong)(yong)機(ji)械方式傳(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)(li)和運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械工程中應用(yong)(yong)非常廣泛，有多(duo)種形式，主要包括皮(pi)帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)動(dong)(dong)(dong)(dong)(dong)和螺旋傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)(neng)夠(gou)用(yong)(yong)于大功率的(de)場(chang)合(he)，傳(chuan)動(dong)(dong)(dong)(dong)(dong)比準確(que)，但(dan)一般要求(qiu)較高的(de)制造精(jing)度和安(an)裝(zhuang)精(jing)度。還(huan)有一類是(shi)靠機(ji)件間的(de)摩擦力(li)(li)傳(chuan)遞動(dong)(dong)(dong)(dong)(dong)力(li)(li)和運(yun)(yun)動(dong)(dong)(dong)(dong)(dong)的(de)摩擦傳(chuan)動(dong)(dong)(dong)(dong)(dong)，包括帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)(dong)(dong)和摩擦輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩擦傳(chuan)動(dong)(dong)(dong)(dong)(dong)容易實(shi)現無級(ji)變速，可以適應軸(zhou)間距較大的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)合(he)，而(er)過載打滑還(huan)能(neng)(neng)起到緩(huan)沖(chong)和保護傳(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的(de)作用(yong)(yong)，但(dan)這種傳(chuan)動(dong)(dong)(dong)(dong)(dong)一般不能(neng)(neng)用(yong)(yong)于大功率的(de)場(chang)合(he)，也不能(neng)(neng)保證準確(que)的(de)傳(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是南坤鎮機械密封的更換工作大(da)同小異，首先拆(chai)前需(xu)確認電機處于(yu)檢修(xiu)狀態，擰下加油(you)螺塞，用吸管把密(mi)封座腔內(nei)的潤滑油(you)吸出(chu)。準備好放(fang)置泵(beng)零件(jian)的工作臺及拆(chai)裝工具，切勿任(ren)意亂放(fang)亂用，避免碰(peng)壞泵(beng)的零部件(jian)。

　　拆對分(fen)式聯軸(zhou)(zhou)(zhou)器：先把聯軸(zhou)(zhou)(zhou)器的固定(ding)內六角螺(luo)釘擰(ning)下來(lai)，再輕(qing)輕(qing)把聯軸(zhou)(zhou)(zhou)器的一(yi)半(ban)從(cong)軸(zhou)(zhou)(zhou)上慢(man)慢(man)拉(la)下，注意不要掉(diao)了，再用梅(mei)花(hua)扳手擰(ning)下泵(beng)軸(zhou)(zhou)(zhou)吊緊螺(luo)栓和擋塊，讓(rang)葉輪慢(man)慢(man)下沉(chen)至(zhi)泵(beng)體，然(ran)后拆下另外一(yi)半(ban)聯軸(zhou)(zhou)(zhou)器，拿下泵(beng)軸(zhou)(zhou)(zhou)擋圈。

　　拆卸南坤鎮機械密封：抓(zhua)住密封彈(dan)簧順著(zhu)泵軸往上(shang)提，就能拆下來了。

　　拆卸并(bing)清洗(xi)軸承座：先輕輕松動一下軸承座后(hou)用拆卸螺栓(shuan)頂起(qi)軸承座，并(bing)且沿著泵軸往上提而(er)卸下，再(zai)用噴(pen)氣(qi)燃(ran)料清洗(xi)軸承及座，裝前晾干并(bing)涂抹少許20號(hao)機械油(you)用來潤滑保護。

　　拆密(mi)封(feng)座：擰(ning)下(xia)密(mi)封(feng)座壓緊(jin)螺母(mu)，輕(qing)輕(qing)卸下(xia)密(mi)封(feng)座并清洗(xi)。

　　南坤鎮機械密封裝(zhuang)配：在(zai)動、靜(jing)(jing)環鏡面上(shang)(shang)(shang)涂一層潔(jie)凈的20號(hao)潤滑油，導軸承(cheng)座也抹上(shang)(shang)(shang)潤滑油，先把靜(jing)(jing)環輕(qing)輕(qing)定位裝(zhuang)入導軸承(cheng)座，再在(zai)泵軸上(shang)(shang)(shang)抹上(shang)(shang)(shang)潤滑油，把動環部(bu)(bu)分(fen)輕(qing)輕(qing)裝(zhuang)入泵軸上(shang)(shang)(shang)，用手(shou)輕(qing)推密(mi)封環應能(neng)伸(shen)縮自如，注意(yi)動、靜(jing)(jing)環部(bu)(bu)分(fen)的防轉部(bu)(bu)位需裝(zhuang)配到位。

　　裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)：在電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)(shang)裝(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)擋圈，裝(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)，再在泵(beng)軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)槽(cao)內(nei)裝(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)擋塊并用(yong)梅花(hua)扳手擰緊(jin)螺(luo)(luo)栓；再裝(zhuang)(zhuang)(zhuang)上(shang)(shang)(shang)另一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)擰上(shang)(shang)(shang)內(nei)六角螺(luo)(luo)釘(ding)。安(an)裝(zhuang)(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)正(zheng)確的檢查要(yao)求：對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)上(shang)(shang)(shang)下間隙需要(yao)均(jun)勻(yun)，用(yong)手盤(pan)動(dong)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)幾(ji)圈檢查轉動(dong)的靈活性。

　　裝密封(feng)(feng)(feng)座：先將密封(feng)(feng)(feng)座裝入(ru)橡(xiang)膠油封(feng)(feng)(feng)，再把密封(feng)(feng)(feng)座裝入(ru)泵蓋并壓在軸承座上(shang)(shang)，擰緊螺(luo)(luo)(luo)母(mu)，確保(bao)所有(you)安裝螺(luo)(luo)(luo)釘緊固(gu)(gu)。當安裝螺(luo)(luo)(luo)釘被用(yong)作密封(feng)(feng)(feng)與(yu)軸之間的(de)驅動時，軸應(ying)打埋頭孔來加固(gu)(gu)連接，緊固(gu)(gu)壓蓋螺(luo)(luo)(luo)栓時應(ying)該平穩緊固(gu)(gu)，并且不(bu)要(yao)使壓蓋受(shou)彈力。在可能的(de)地方(fang)使用(yong)4個以(yi)上(shang)(shang)螺(luo)(luo)(luo)釘的(de)等間距壓蓋，緊固(gu)(gu)壓蓋螺(luo)(luo)(luo)栓時，用(yong)塞尺檢查軸與(yu)壓蓋之間的(de)間隙，這在密封(feng)(feng)(feng)腔對壓蓋不(bu)導向時，顯得特別(bie)重要(yao)，因為壓蓋必(bi)須(xu)對中。
