　　傳動形式多，但是建華機械密封的(de)更換工(gong)(gong)作(zuo)大(da)同小(xiao)異(yi)，首先拆前需確認(ren)電機處于檢修狀態，擰下加油(you)螺塞(sai)，用(yong)吸管(guan)把密封座腔內的(de)潤滑(hua)油(you)吸出(chu)。準備(bei)好放置泵零件的(de)工(gong)(gong)作(zuo)臺及拆裝工(gong)(gong)具，切勿(wu)任意(yi)亂放亂用(yong)，避免碰(peng)壞泵的(de)零部件。

　　拆對分式聯(lian)(lian)軸(zhou)(zhou)器：先把(ba)聯(lian)(lian)軸(zhou)(zhou)器的固定(ding)內(nei)六角螺釘擰(ning)下來，再輕輕把(ba)聯(lian)(lian)軸(zhou)(zhou)器的一(yi)半從軸(zhou)(zhou)上慢慢拉下，注意不要掉了(le)，再用梅花扳手(shou)擰(ning)下泵(beng)軸(zhou)(zhou)吊緊螺栓和擋(dang)塊，讓(rang)葉輪慢慢下沉至泵(beng)體，然后拆下另外一(yi)半聯(lian)(lian)軸(zhou)(zhou)器，拿下泵(beng)軸(zhou)(zhou)擋(dang)圈。

　　拆卸建華機械密封：抓住密(mi)封(feng)彈簧順著(zhu)泵軸往上(shang)提(ti)，就能拆下來(lai)了。

　　拆卸并(bing)清洗(xi)軸承(cheng)座：先輕輕松動一下軸承(cheng)座后(hou)用拆卸螺栓頂起軸承(cheng)座，并(bing)且沿著泵軸往上(shang)提而卸下，再用噴氣燃料(liao)清洗(xi)軸承(cheng)及座，裝(zhuang)前晾干并(bing)涂抹少許20號(hao)機械(xie)油用來潤滑保護。

　　拆(chai)密封(feng)座：擰下(xia)密封(feng)座壓緊螺母，輕輕卸下(xia)密封(feng)座并清洗。

　　建華機械密封裝配：在動、靜(jing)環(huan)(huan)鏡面上(shang)涂一層潔凈的20號潤滑(hua)油，導軸(zhou)(zhou)承(cheng)座也抹上(shang)潤滑(hua)油，先把(ba)靜(jing)環(huan)(huan)輕輕定位裝入導軸(zhou)(zhou)承(cheng)座，再在泵軸(zhou)(zhou)上(shang)抹上(shang)潤滑(hua)油，把(ba)動環(huan)(huan)部(bu)分輕輕裝入泵軸(zhou)(zhou)上(shang)，用(yong)手輕推密封環(huan)(huan)應能伸縮自如，注意動、靜(jing)環(huan)(huan)部(bu)分的防轉部(bu)位需裝配到位。

　　裝聯軸(zhou)器：在電機(ji)軸(zhou)頭上(shang)裝上(shang)擋圈，裝上(shang)一半(ban)聯軸(zhou)器，再在泵軸(zhou)端(duan)和聯軸(zhou)器槽內裝上(shang)擋塊并用(yong)梅花扳手擰緊螺(luo)(luo)栓；再裝上(shang)另一半(ban)聯軸(zhou)器擰上(shang)內六角螺(luo)(luo)釘。安裝聯軸(zhou)器正確(que)的檢查要求：對分式聯軸(zhou)器上(shang)下(xia)間隙需要均勻(yun)，用(yong)手盤(pan)動(dong)聯軸(zhou)器幾(ji)圈檢查轉動(dong)的靈(ling)活性。

　　裝(zhuang)密(mi)(mi)封(feng)(feng)(feng)座(zuo)：先將密(mi)(mi)封(feng)(feng)(feng)座(zuo)裝(zhuang)入橡(xiang)膠油封(feng)(feng)(feng)，再把密(mi)(mi)封(feng)(feng)(feng)座(zuo)裝(zhuang)入泵蓋(gai)(gai)并壓(ya)(ya)(ya)(ya)在軸承(cheng)座(zuo)上，擰(ning)緊(jin)螺(luo)母(mu)，確(que)保所(suo)有(you)安裝(zhuang)螺(luo)釘緊(jin)固。當安裝(zhuang)螺(luo)釘被用(yong)(yong)作密(mi)(mi)封(feng)(feng)(feng)與軸之間的(de)驅動時(shi)，軸應(ying)打埋頭孔來(lai)加(jia)固連(lian)接，緊(jin)固壓(ya)(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時(shi)應(ying)該平穩緊(jin)固，并且不(bu)(bu)要(yao)使壓(ya)(ya)(ya)(ya)蓋(gai)(gai)受(shou)彈(dan)力。在可能的(de)地方(fang)使用(yong)(yong)4個以(yi)上螺(luo)釘的(de)等間距壓(ya)(ya)(ya)(ya)蓋(gai)(gai)，緊(jin)固壓(ya)(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時(shi)，用(yong)(yong)塞尺檢(jian)查軸與壓(ya)(ya)(ya)(ya)蓋(gai)(gai)之間的(de)間隙，這(zhe)在密(mi)(mi)封(feng)(feng)(feng)腔對壓(ya)(ya)(ya)(ya)蓋(gai)(gai)不(bu)(bu)導向(xiang)時(shi)，顯(xian)得(de)特別重要(yao)，因(yin)為壓(ya)(ya)(ya)(ya)蓋(gai)(gai)必須對中。
