　　傳動形式多，但是新縣機械密封的更(geng)換工(gong)作大同小異(yi)，首先拆(chai)前需確認電機處于檢修狀態，擰(ning)下(xia)加油螺塞，用吸管把密封座腔內(nei)的潤滑(hua)油吸出。準備好放置泵零(ling)(ling)件的工(gong)作臺及拆(chai)裝(zhuang)工(gong)具(ju)，切勿任(ren)意亂放亂用，避免碰壞泵的零(ling)(ling)部件。

　　拆對(dui)分式聯(lian)(lian)軸(zhou)(zhou)器：先把聯(lian)(lian)軸(zhou)(zhou)器的(de)固定內六角螺釘擰下來，再輕輕把聯(lian)(lian)軸(zhou)(zhou)器的(de)一(yi)半從軸(zhou)(zhou)上慢慢拉下，注(zhu)意不(bu)要掉了，再用梅花扳(ban)手擰下泵(beng)軸(zhou)(zhou)吊(diao)緊螺栓和(he)擋塊(kuai)，讓葉輪慢慢下沉至(zhi)泵(beng)體，然(ran)后(hou)拆下另外一(yi)半聯(lian)(lian)軸(zhou)(zhou)器，拿下泵(beng)軸(zhou)(zhou)擋圈。

　　拆卸新縣機械密封：抓住密封彈簧順著(zhu)泵(beng)軸往上提，就能拆下(xia)來了(le)。

　　拆卸并清洗軸(zhou)承座(zuo)：先輕(qing)(qing)輕(qing)(qing)松(song)動一下軸(zhou)承座(zuo)后用(yong)(yong)拆卸螺栓頂(ding)起軸(zhou)承座(zuo)，并且沿著泵軸(zhou)往上提而卸下，再用(yong)(yong)噴(pen)氣燃料清洗軸(zhou)承及座(zuo)，裝(zhuang)前晾(liang)干并涂抹少許20號機(ji)械(xie)油(you)用(yong)(yong)來(lai)潤滑保護(hu)。

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

　　新縣機械密封裝配(pei)：在(zai)動、靜(jing)環鏡面上(shang)涂一層潔(jie)凈的20號潤(run)(run)滑油，導軸(zhou)承座也抹上(shang)潤(run)(run)滑油，先把靜(jing)環輕(qing)輕(qing)定位(wei)裝入(ru)導軸(zhou)承座，再在(zai)泵軸(zhou)上(shang)抹上(shang)潤(run)(run)滑油，把動環部分(fen)(fen)輕(qing)輕(qing)裝入(ru)泵軸(zhou)上(shang)，用手輕(qing)推密封環應能伸(shen)縮(suo)自如，注意動、靜(jing)環部分(fen)(fen)的防轉部位(wei)需裝配(pei)到位(wei)。

　　裝(zhuang)(zhuang)(zhuang)聯軸(zhou)(zhou)器：在電機軸(zhou)(zhou)頭(tou)上(shang)(shang)裝(zhuang)(zhuang)(zhuang)上(shang)(shang)擋(dang)(dang)圈，裝(zhuang)(zhuang)(zhuang)上(shang)(shang)一半聯軸(zhou)(zhou)器，再在泵(beng)軸(zhou)(zhou)端和聯軸(zhou)(zhou)器槽(cao)內裝(zhuang)(zhuang)(zhuang)上(shang)(shang)擋(dang)(dang)塊并用梅花扳手(shou)擰(ning)緊螺(luo)栓；再裝(zhuang)(zhuang)(zhuang)上(shang)(shang)另一半聯軸(zhou)(zhou)器擰(ning)上(shang)(shang)內六角螺(luo)釘(ding)。安裝(zhuang)(zhuang)(zhuang)聯軸(zhou)(zhou)器正確的檢查(cha)要(yao)求：對分式聯軸(zhou)(zhou)器上(shang)(shang)下間隙需(xu)要(yao)均勻(yun)，用手(shou)盤動(dong)聯軸(zhou)(zhou)器幾圈檢查(cha)轉動(dong)的靈活性。

　　裝密(mi)封(feng)(feng)座：先將密(mi)封(feng)(feng)座裝入橡(xiang)膠油封(feng)(feng)，再把密(mi)封(feng)(feng)座裝入泵(beng)蓋(gai)(gai)(gai)并(bing)壓(ya)(ya)(ya)在(zai)軸承(cheng)座上，擰緊(jin)螺(luo)母，確保所(suo)有安裝螺(luo)釘(ding)緊(jin)固(gu)。當安裝螺(luo)釘(ding)被(bei)用(yong)(yong)作密(mi)封(feng)(feng)與軸之間(jian)(jian)的(de)驅動時，軸應打埋頭孔來加固(gu)連接，緊(jin)固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓(shuan)時應該平穩緊(jin)固(gu)，并(bing)且不(bu)要(yao)使(shi)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)受彈(dan)力。在(zai)可(ke)能的(de)地方使(shi)用(yong)(yong)4個以(yi)上螺(luo)釘(ding)的(de)等間(jian)(jian)距壓(ya)(ya)(ya)蓋(gai)(gai)(gai)，緊(jin)固(gu)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓(shuan)時，用(yong)(yong)塞尺檢查軸與壓(ya)(ya)(ya)蓋(gai)(gai)(gai)之間(jian)(jian)的(de)間(jian)(jian)隙，這在(zai)密(mi)封(feng)(feng)腔對壓(ya)(ya)(ya)蓋(gai)(gai)(gai)不(bu)導向(xiang)時，顯(xian)得特別重要(yao)，因為壓(ya)(ya)(ya)蓋(gai)(gai)(gai)必須對中。
