南湖機械密封利用(yong)(yong)機(ji)(ji)(ji)械(xie)(xie)方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)，機(ji)(ji)(ji)械(xie)(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)在機(ji)(ji)(ji)械(xie)(xie)工程中應(ying)(ying)用(yong)(yong)非常廣泛，有多(duo)種(zhong)形式，主要包括皮(pi)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸(gua)桿蝸(gua)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)(chi)輪齒(chi)(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。齒(chi)(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)能夠用(yong)(yong)于大功率的(de)場(chang)(chang)合(he)，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)比準確(que)，但(dan)一般要求較(jiao)高的(de)制造精度(du)和安(an)裝(zhuang)精度(du)。還(huan)有一類(lei)是靠機(ji)(ji)(ji)件間(jian)的(de)摩(mo)擦力傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的(de)摩(mo)擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和摩(mo)擦輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。摩(mo)擦傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易實現無級(ji)變(bian)速，可以適應(ying)(ying)軸間(jian)距較(jiao)大的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)場(chang)(chang)合(he)，而過載打滑還(huan)能起(qi)到緩沖和保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝(zhuang)置(zhi)的(de)作(zuo)用(yong)(yong)，但(dan)這種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)一般不能用(yong)(yong)于大功率的(de)場(chang)(chang)合(he)，也不能保證準確(que)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)比。

　　傳動形式多，但是南湖機械密封的(de)更換工(gong)作大同(tong)小異，首先拆前需(xu)確認電機(ji)處(chu)于檢修狀態，擰下(xia)加油螺(luo)塞，用(yong)吸管把密封座腔內的(de)潤滑油吸出。準備好放置(zhi)泵零(ling)件(jian)的(de)工(gong)作臺及拆裝工(gong)具，切勿(wu)任意(yi)亂放亂用(yong)，避免碰(peng)壞泵的(de)零(ling)部件(jian)。

　　拆(chai)(chai)對(dui)分式聯軸(zhou)(zhou)(zhou)器：先把聯軸(zhou)(zhou)(zhou)器的固定內六角螺(luo)釘擰下(xia)(xia)(xia)來，再輕輕把聯軸(zhou)(zhou)(zhou)器的一半從軸(zhou)(zhou)(zhou)上慢慢拉下(xia)(xia)(xia)，注(zhu)意不要掉了，再用梅花扳(ban)手(shou)擰下(xia)(xia)(xia)泵軸(zhou)(zhou)(zhou)吊緊螺(luo)栓和擋(dang)塊，讓葉(xie)輪(lun)慢慢下(xia)(xia)(xia)沉至(zhi)泵體，然后拆(chai)(chai)下(xia)(xia)(xia)另外(wai)一半聯軸(zhou)(zhou)(zhou)器，拿下(xia)(xia)(xia)泵軸(zhou)(zhou)(zhou)擋(dang)圈(quan)。

　　拆卸南湖機械密封：抓住密封(feng)彈簧順著泵(beng)軸往(wang)上提，就能(neng)拆下(xia)來了。

　　拆卸(xie)并(bing)清洗軸(zhou)承座：先輕輕松動一(yi)下軸(zhou)承座后用(yong)拆卸(xie)螺(luo)栓頂起軸(zhou)承座，并(bing)且沿著泵軸(zhou)往(wang)上(shang)提而(er)卸(xie)下，再用(yong)噴氣燃料清洗軸(zhou)承及(ji)座，裝前晾干并(bing)涂抹少許20號機械油用(yong)來潤(run)滑(hua)保護。

　　拆密封座(zuo)：擰下密封座(zuo)壓緊螺母(mu)，輕輕卸下密封座(zuo)并清洗。

　　南湖機械密封裝(zhuang)配(pei)：在動、靜(jing)環(huan)鏡面上(shang)(shang)涂一(yi)層潔凈的20號潤滑油(you)，導軸(zhou)承座也抹上(shang)(shang)潤滑油(you)，先把靜(jing)環(huan)輕(qing)(qing)輕(qing)(qing)定位裝(zhuang)入(ru)導軸(zhou)承座，再在泵軸(zhou)上(shang)(shang)抹上(shang)(shang)潤滑油(you)，把動環(huan)部分輕(qing)(qing)輕(qing)(qing)裝(zhuang)入(ru)泵軸(zhou)上(shang)(shang)，用手輕(qing)(qing)推密(mi)封環(huan)應(ying)能伸縮自(zi)如(ru)，注意動、靜(jing)環(huan)部分的防轉部位需裝(zhuang)配(pei)到位。

　　裝(zhuang)聯軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)：在電(dian)機軸(zhou)(zhou)(zhou)頭上裝(zhuang)上擋圈，裝(zhuang)上一半聯軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)，再在泵(beng)軸(zhou)(zhou)(zhou)端和聯軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)槽(cao)內(nei)裝(zhuang)上擋塊并用梅花扳手(shou)擰緊螺(luo)栓；再裝(zhuang)上另(ling)一半聯軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)擰上內(nei)六(liu)角螺(luo)釘。安裝(zhuang)聯軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)正(zheng)確(que)的檢查要求：對分式(shi)聯軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)上下間隙需要均(jun)勻，用手(shou)盤動聯軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)幾圈檢查轉動的靈活(huo)性(xing)。

　　裝(zhuang)(zhuang)密封(feng)(feng)座：先將密封(feng)(feng)座裝(zhuang)(zhuang)入(ru)橡膠油封(feng)(feng)，再把密封(feng)(feng)座裝(zhuang)(zhuang)入(ru)泵蓋(gai)并(bing)壓(ya)(ya)在軸(zhou)承座上(shang)，擰緊(jin)(jin)螺(luo)母(mu)，確保所有安裝(zhuang)(zhuang)螺(luo)釘緊(jin)(jin)固(gu)(gu)(gu)。當安裝(zhuang)(zhuang)螺(luo)釘被(bei)用(yong)作密封(feng)(feng)與軸(zhou)之間(jian)的(de)驅(qu)動時(shi)(shi)，軸(zhou)應打(da)埋頭孔(kong)來加固(gu)(gu)(gu)連接，緊(jin)(jin)固(gu)(gu)(gu)壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時(shi)(shi)應該平穩緊(jin)(jin)固(gu)(gu)(gu)，并(bing)且不要使(shi)壓(ya)(ya)蓋(gai)受(shou)彈(dan)力(li)。在可能的(de)地(di)方(fang)使(shi)用(yong)4個以上(shang)螺(luo)釘的(de)等間(jian)距壓(ya)(ya)蓋(gai)，緊(jin)(jin)固(gu)(gu)(gu)壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時(shi)(shi)，用(yong)塞(sai)尺檢(jian)查軸(zhou)與壓(ya)(ya)蓋(gai)之間(jian)的(de)間(jian)隙，這在密封(feng)(feng)腔(qiang)對壓(ya)(ya)蓋(gai)不導向時(shi)(shi)，顯得特別重要，因為壓(ya)(ya)蓋(gai)必(bi)須對中(zhong)。
