　　傳動形式多，但是南林鄉機械密封的(de)更換(huan)工作大同小異，首先拆前需確認電機處(chu)于檢修狀態(tai)，擰(ning)下加(jia)油(you)螺塞，用吸管把(ba)密封座(zuo)腔內的(de)潤滑(hua)油(you)吸出。準備好放置泵零(ling)件(jian)的(de)工作臺及拆裝工具，切(qie)勿任意亂放亂用，避免碰壞泵的(de)零(ling)部(bu)件(jian)。

　　拆(chai)對分式聯軸(zhou)(zhou)器：先把(ba)聯軸(zhou)(zhou)器的固定內六角(jiao)螺釘(ding)擰下(xia)來，再輕(qing)輕(qing)把(ba)聯軸(zhou)(zhou)器的一半(ban)從軸(zhou)(zhou)上慢(man)(man)慢(man)(man)拉(la)下(xia)，注意(yi)不要掉了，再用梅花扳手擰下(xia)泵(beng)(beng)軸(zhou)(zhou)吊緊(jin)螺栓和(he)擋塊，讓葉輪慢(man)(man)慢(man)(man)下(xia)沉至泵(beng)(beng)體，然后(hou)拆(chai)下(xia)另外一半(ban)聯軸(zhou)(zhou)器，拿下(xia)泵(beng)(beng)軸(zhou)(zhou)擋圈。

　　拆卸南林鄉機械密封：抓(zhua)住密封彈簧順(shun)著泵軸(zhou)往上(shang)提，就能拆(chai)下(xia)來了。

　　拆卸(xie)并(bing)清(qing)洗軸(zhou)承座：先輕輕松動一下軸(zhou)承座后用(yong)拆卸(xie)螺栓(shuan)頂起軸(zhou)承座，并(bing)且(qie)沿著泵軸(zhou)往上提而卸(xie)下，再用(yong)噴氣燃料清(qing)洗軸(zhou)承及座，裝前晾干并(bing)涂抹少許20號機(ji)械油(you)用(yong)來潤(run)滑(hua)保護。

　　拆密(mi)封座：擰下密(mi)封座壓緊螺母，輕(qing)輕(qing)卸(xie)下密(mi)封座并清洗。

　　南林鄉機械密封裝(zhuang)配：在動、靜環鏡面上(shang)(shang)涂一(yi)層潔凈的(de)20號潤(run)滑(hua)油(you)，導軸承(cheng)(cheng)座也抹上(shang)(shang)潤(run)滑(hua)油(you)，先把靜環輕輕定位(wei)裝(zhuang)入(ru)導軸承(cheng)(cheng)座，再在泵軸上(shang)(shang)抹上(shang)(shang)潤(run)滑(hua)油(you)，把動環部分輕輕裝(zhuang)入(ru)泵軸上(shang)(shang)，用手(shou)輕推密封環應能伸縮(suo)自如，注意動、靜環部分的(de)防轉部位(wei)需裝(zhuang)配到位(wei)。

　　裝聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)：在電(dian)機軸(zhou)(zhou)(zhou)頭上(shang)裝上(shang)擋圈，裝上(shang)一半聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)槽內裝上(shang)擋塊并用梅花扳手擰(ning)緊(jin)螺栓；再裝上(shang)另一半聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)擰(ning)上(shang)內六(liu)角螺釘。安裝聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)正(zheng)確(que)的檢查要求：對分(fen)式聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)上(shang)下間隙需(xu)要均勻，用手盤動聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)幾(ji)圈檢查轉動的靈(ling)活性。

　　裝(zhuang)密(mi)封(feng)座：先將(jiang)密(mi)封(feng)座裝(zhuang)入橡膠(jiao)油封(feng)，再把密(mi)封(feng)座裝(zhuang)入泵(beng)蓋(gai)(gai)(gai)并壓(ya)(ya)在軸(zhou)承座上，擰緊(jin)螺(luo)(luo)母(mu)，確保所有安裝(zhuang)螺(luo)(luo)釘(ding)緊(jin)固(gu)(gu)。當安裝(zhuang)螺(luo)(luo)釘(ding)被用(yong)作密(mi)封(feng)與(yu)軸(zhou)之間的驅動時(shi)(shi)，軸(zhou)應打埋頭孔來加(jia)固(gu)(gu)連接(jie)，緊(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi)(shi)應該平(ping)穩緊(jin)固(gu)(gu)，并且不(bu)要使壓(ya)(ya)蓋(gai)(gai)(gai)受(shou)彈(dan)力。在可(ke)能的地(di)方使用(yong)4個以上螺(luo)(luo)釘(ding)的等間距壓(ya)(ya)蓋(gai)(gai)(gai)，緊(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi)(shi)，用(yong)塞尺檢查軸(zhou)與(yu)壓(ya)(ya)蓋(gai)(gai)(gai)之間的間隙，這在密(mi)封(feng)腔(qiang)對壓(ya)(ya)蓋(gai)(gai)(gai)不(bu)導向時(shi)(shi)，顯(xian)得特別重(zhong)要，因為壓(ya)(ya)蓋(gai)(gai)(gai)必須(xu)對中。
