　　傳動形式多，但是南華機械密封的更換(huan)工(gong)作(zuo)(zuo)大同小異，首先(xian)拆前需確認電(dian)機處于檢修狀態(tai)，擰(ning)下(xia)加(jia)油螺(luo)塞，用(yong)吸管把密封座腔內的潤滑油吸出。準備好(hao)放置泵零件(jian)的工(gong)作(zuo)(zuo)臺及拆裝工(gong)具，切勿任意亂(luan)放亂(luan)用(yong)，避免(mian)碰壞泵的零部件(jian)。

　　拆對(dui)分式(shi)聯(lian)軸(zhou)器(qi)：先把聯(lian)軸(zhou)器(qi)的固定內六角螺(luo)(luo)釘(ding)擰(ning)下來(lai)，再輕輕把聯(lian)軸(zhou)器(qi)的一(yi)半(ban)從軸(zhou)上慢(man)(man)慢(man)(man)拉下，注意不要(yao)掉了(le)，再用梅花扳手擰(ning)下泵(beng)軸(zhou)吊緊螺(luo)(luo)栓和擋塊(kuai)，讓葉輪慢(man)(man)慢(man)(man)下沉至泵(beng)體(ti)，然后(hou)拆下另外一(yi)半(ban)聯(lian)軸(zhou)器(qi)，拿下泵(beng)軸(zhou)擋圈。

　　拆卸南華機械密封：抓住密封彈簧(huang)順著泵軸往上提，就能(neng)拆下來了。

　　拆(chai)卸并清(qing)洗軸(zhou)(zhou)(zhou)承(cheng)座(zuo)(zuo)(zuo)：先輕(qing)輕(qing)松動一(yi)下軸(zhou)(zhou)(zhou)承(cheng)座(zuo)(zuo)(zuo)后用拆(chai)卸螺(luo)栓頂起軸(zhou)(zhou)(zhou)承(cheng)座(zuo)(zuo)(zuo)，并且沿著泵軸(zhou)(zhou)(zhou)往上提而卸下，再用噴(pen)氣燃料清(qing)洗軸(zhou)(zhou)(zhou)承(cheng)及座(zuo)(zuo)(zuo)，裝前晾干并涂抹少許20號機(ji)械油用來潤(run)滑(hua)保護。

　　拆密封(feng)座(zuo)：擰下密封(feng)座(zuo)壓緊螺母，輕輕卸(xie)下密封(feng)座(zuo)并清(qing)洗。

　　南華機械密封裝(zhuang)配(pei)：在動、靜(jing)環(huan)鏡面上(shang)(shang)涂一層潔凈的20號潤(run)(run)滑(hua)油，導軸承座也抹上(shang)(shang)潤(run)(run)滑(hua)油，先把靜(jing)環(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)入(ru)(ru)導軸承座，再在泵軸上(shang)(shang)抹上(shang)(shang)潤(run)(run)滑(hua)油，把動環(huan)部(bu)分輕(qing)輕(qing)裝(zhuang)入(ru)(ru)泵軸上(shang)(shang)，用手輕(qing)推密封(feng)環(huan)應(ying)能(neng)伸縮自如，注(zhu)意動、靜(jing)環(huan)部(bu)分的防轉部(bu)位(wei)需(xu)裝(zhuang)配(pei)到位(wei)。

　　裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)：在(zai)電(dian)機軸(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋圈，裝(zhuang)上(shang)(shang)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)，再在(zai)泵軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)槽(cao)內裝(zhuang)上(shang)(shang)擋塊并用梅花扳手(shou)擰緊(jin)螺栓；再裝(zhuang)上(shang)(shang)另一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)擰上(shang)(shang)內六角螺釘。安(an)裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)正確的(de)檢查要求：對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)上(shang)(shang)下(xia)間隙需(xu)要均(jun)勻，用手(shou)盤動聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈檢查轉動的(de)靈活性(xing)。

　　裝密(mi)封(feng)座(zuo)：先將密(mi)封(feng)座(zuo)裝入橡(xiang)膠(jiao)油(you)封(feng)，再把密(mi)封(feng)座(zuo)裝入泵(beng)蓋(gai)(gai)并壓(ya)(ya)在軸(zhou)(zhou)承(cheng)座(zuo)上(shang)，擰緊(jin)螺(luo)母(mu)，確保所(suo)有安(an)裝螺(luo)釘緊(jin)固(gu)(gu)。當安(an)裝螺(luo)釘被用(yong)(yong)(yong)作密(mi)封(feng)與軸(zhou)(zhou)之(zhi)間的驅動(dong)時(shi)，軸(zhou)(zhou)應打(da)埋頭(tou)孔(kong)來加固(gu)(gu)連接，緊(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)應該平(ping)穩(wen)緊(jin)固(gu)(gu)，并且不(bu)要使壓(ya)(ya)蓋(gai)(gai)受彈力(li)。在可能(neng)的地方使用(yong)(yong)(yong)4個以上(shang)螺(luo)釘的等間距(ju)壓(ya)(ya)蓋(gai)(gai)，緊(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)，用(yong)(yong)(yong)塞尺檢查軸(zhou)(zhou)與壓(ya)(ya)蓋(gai)(gai)之(zhi)間的間隙，這在密(mi)封(feng)腔對壓(ya)(ya)蓋(gai)(gai)不(bu)導向時(shi)，顯(xian)得特別重要，因為壓(ya)(ya)蓋(gai)(gai)必須對中。
