麻涌鎮機械密封利用(yong)機(ji)械(xie)方式傳(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)(li)和(he)(he)運動(dong)(dong)(dong)(dong)(dong)的傳(chuan)動(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)動(dong)(dong)(dong)(dong)(dong)在機(ji)械(xie)工程中應用(yong)非(fei)常廣泛，有多(duo)種形式，主要包(bao)括皮帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)動(dong)(dong)(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、齒輪(lun)(lun)齒條傳(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)螺旋傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。齒輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)能(neng)夠用(yong)于(yu)大功(gong)率(lv)的場(chang)(chang)合(he)，傳(chuan)動(dong)(dong)(dong)(dong)(dong)比準確，但(dan)一般要求較高的制造精度(du)和(he)(he)安裝(zhuang)精度(du)。還有一類是靠機(ji)件間(jian)的摩(mo)(mo)擦力(li)(li)傳(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)力(li)(li)和(he)(he)運動(dong)(dong)(dong)(dong)(dong)的摩(mo)(mo)擦傳(chuan)動(dong)(dong)(dong)(dong)(dong)，包(bao)括帶傳(chuan)動(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)動(dong)(dong)(dong)(dong)(dong)和(he)(he)摩(mo)(mo)擦輪(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)等。摩(mo)(mo)擦傳(chuan)動(dong)(dong)(dong)(dong)(dong)容易實現(xian)無級變(bian)速，可以適應軸(zhou)間(jian)距較大的傳(chuan)動(dong)(dong)(dong)(dong)(dong)場(chang)(chang)合(he)，而過(guo)載打(da)滑還能(neng)起到(dao)緩沖和(he)(he)保護傳(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置的作用(yong)，但(dan)這(zhe)種傳(chuan)動(dong)(dong)(dong)(dong)(dong)一般不能(neng)用(yong)于(yu)大功(gong)率(lv)的場(chang)(chang)合(he)，也不能(neng)保證準確的傳(chuan)動(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是麻涌鎮機械密封的更(geng)換工作大同小(xiao)異，首先(xian)拆前(qian)需確認(ren)電機處于(yu)檢修狀態，擰下加油螺塞(sai)，用吸(xi)管把密封座腔內(nei)的潤滑油吸(xi)出。準備(bei)好放置泵零(ling)件的工作臺及拆裝工具，切勿(wu)任(ren)意亂(luan)放亂(luan)用，避免碰(peng)壞泵的零(ling)部件。

　　拆(chai)對分(fen)式聯軸(zhou)(zhou)器(qi)(qi)：先把聯軸(zhou)(zhou)器(qi)(qi)的固(gu)定內六角螺(luo)釘擰下(xia)(xia)來(lai)，再(zai)輕(qing)輕(qing)把聯軸(zhou)(zhou)器(qi)(qi)的一(yi)半從軸(zhou)(zhou)上慢慢拉(la)下(xia)(xia)，注意不要掉(diao)了(le)，再(zai)用(yong)梅花(hua)扳手擰下(xia)(xia)泵軸(zhou)(zhou)吊緊螺(luo)栓和(he)擋(dang)塊，讓葉輪慢慢下(xia)(xia)沉至(zhi)泵體(ti)，然(ran)后拆(chai)下(xia)(xia)另外一(yi)半聯軸(zhou)(zhou)器(qi)(qi)，拿下(xia)(xia)泵軸(zhou)(zhou)擋(dang)圈。

　　拆卸麻涌鎮機械密封：抓住(zhu)密封(feng)彈簧順著泵軸往上提(ti)，就能拆(chai)下來了。

　　拆卸(xie)并(bing)清(qing)洗軸(zhou)(zhou)(zhou)承座(zuo)：先輕輕松(song)動一下軸(zhou)(zhou)(zhou)承座(zuo)后用(yong)拆卸(xie)螺栓頂起軸(zhou)(zhou)(zhou)承座(zuo)，并(bing)且沿(yan)著泵軸(zhou)(zhou)(zhou)往上提而卸(xie)下，再用(yong)噴(pen)氣(qi)燃料清(qing)洗軸(zhou)(zhou)(zhou)承及(ji)座(zuo)，裝前(qian)晾(liang)干(gan)并(bing)涂抹少許20號(hao)機械油用(yong)來潤滑保護。

　　拆密(mi)封(feng)座：擰下(xia)密(mi)封(feng)座壓緊(jin)螺母，輕輕卸下(xia)密(mi)封(feng)座并清洗。

　　麻涌鎮機械密封裝(zhuang)(zhuang)配：在動、靜環(huan)(huan)鏡面上涂一層潔凈的20號潤滑油(you)，導(dao)軸承座(zuo)也抹上潤滑油(you)，先把(ba)靜環(huan)(huan)輕(qing)(qing)輕(qing)(qing)定位(wei)裝(zhuang)(zhuang)入(ru)導(dao)軸承座(zuo)，再在泵軸上抹上潤滑油(you)，把(ba)動環(huan)(huan)部(bu)分輕(qing)(qing)輕(qing)(qing)裝(zhuang)(zhuang)入(ru)泵軸上，用手輕(qing)(qing)推密封環(huan)(huan)應能(neng)伸縮自如，注意(yi)動、靜環(huan)(huan)部(bu)分的防轉(zhuan)部(bu)位(wei)需裝(zhuang)(zhuang)配到(dao)位(wei)。

　　裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)：在(zai)電機軸(zhou)(zhou)頭(tou)上(shang)裝(zhuang)(zhuang)上(shang)擋(dang)圈(quan)，裝(zhuang)(zhuang)上(shang)一(yi)(yi)半(ban)聯(lian)(lian)軸(zhou)(zhou)器(qi)，再在(zai)泵軸(zhou)(zhou)端和(he)聯(lian)(lian)軸(zhou)(zhou)器(qi)槽內(nei)裝(zhuang)(zhuang)上(shang)擋(dang)塊并用梅花扳手擰緊(jin)螺栓；再裝(zhuang)(zhuang)上(shang)另(ling)一(yi)(yi)半(ban)聯(lian)(lian)軸(zhou)(zhou)器(qi)擰上(shang)內(nei)六(liu)角螺釘(ding)。安裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)正確的檢查要求：對(dui)分(fen)式聯(lian)(lian)軸(zhou)(zhou)器(qi)上(shang)下間隙需要均(jun)勻，用手盤動聯(lian)(lian)軸(zhou)(zhou)器(qi)幾圈(quan)檢查轉動的靈活性。

　　裝(zhuang)密(mi)封(feng)(feng)座(zuo)：先將(jiang)密(mi)封(feng)(feng)座(zuo)裝(zhuang)入(ru)橡(xiang)膠油封(feng)(feng)，再把密(mi)封(feng)(feng)座(zuo)裝(zhuang)入(ru)泵蓋(gai)(gai)(gai)并壓(ya)(ya)在軸(zhou)承座(zuo)上，擰緊(jin)(jin)螺(luo)母，確保所有安裝(zhuang)螺(luo)釘緊(jin)(jin)固(gu)。當安裝(zhuang)螺(luo)釘被用作密(mi)封(feng)(feng)與軸(zhou)之間(jian)的(de)驅動(dong)時(shi)，軸(zhou)應(ying)打埋頭孔來加固(gu)連接，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓時(shi)應(ying)該平穩(wen)緊(jin)(jin)固(gu)，并且不(bu)要使壓(ya)(ya)蓋(gai)(gai)(gai)受彈力。在可能的(de)地(di)方使用4個以上螺(luo)釘的(de)等間(jian)距壓(ya)(ya)蓋(gai)(gai)(gai)，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓時(shi)，用塞尺檢查軸(zhou)與壓(ya)(ya)蓋(gai)(gai)(gai)之間(jian)的(de)間(jian)隙，這在密(mi)封(feng)(feng)腔對(dui)壓(ya)(ya)蓋(gai)(gai)(gai)不(bu)導(dao)向時(shi)，顯得(de)特別重要，因為(wei)壓(ya)(ya)蓋(gai)(gai)(gai)必須(xu)對(dui)中。
