　　傳動形式多，但是隴南機械密封的更換(huan)工(gong)作大同小異，首先拆前需確認電機處(chu)于(yu)檢(jian)修狀態，擰(ning)下(xia)加(jia)油螺塞，用吸管把密封座(zuo)腔內(nei)的潤滑(hua)油吸出。準(zhun)備(bei)好(hao)放置泵零件的工(gong)作臺(tai)及(ji)拆裝工(gong)具，切勿(wu)任意亂(luan)放亂(luan)用，避免碰壞泵的零部件。

　　拆(chai)對(dui)分式聯(lian)(lian)軸(zhou)器(qi)：先把聯(lian)(lian)軸(zhou)器(qi)的固(gu)定內六角螺釘擰下(xia)(xia)(xia)來，再輕輕把聯(lian)(lian)軸(zhou)器(qi)的一(yi)半(ban)從軸(zhou)上慢(man)(man)慢(man)(man)拉下(xia)(xia)(xia)，注(zhu)意(yi)不要掉了，再用梅花(hua)扳手擰下(xia)(xia)(xia)泵軸(zhou)吊緊(jin)螺栓和擋塊(kuai)，讓葉輪慢(man)(man)慢(man)(man)下(xia)(xia)(xia)沉(chen)至泵體，然后拆(chai)下(xia)(xia)(xia)另外一(yi)半(ban)聯(lian)(lian)軸(zhou)器(qi)，拿下(xia)(xia)(xia)泵軸(zhou)擋圈(quan)。

　　拆卸隴南機械密封：抓住密(mi)封彈簧順著泵軸(zhou)往上提，就(jiu)能拆下來了。

　　拆卸(xie)并(bing)(bing)清(qing)洗(xi)軸(zhou)(zhou)(zhou)(zhou)承(cheng)座：先輕輕松動一下(xia)軸(zhou)(zhou)(zhou)(zhou)承(cheng)座后(hou)用(yong)拆卸(xie)螺栓頂起軸(zhou)(zhou)(zhou)(zhou)承(cheng)座，并(bing)(bing)且沿著泵軸(zhou)(zhou)(zhou)(zhou)往上提而卸(xie)下(xia)，再用(yong)噴氣燃料(liao)清(qing)洗(xi)軸(zhou)(zhou)(zhou)(zhou)承(cheng)及座，裝(zhuang)前晾干并(bing)(bing)涂抹少許20號機械油用(yong)來潤滑(hua)保護。

　　拆密(mi)(mi)封座(zuo)：擰下(xia)密(mi)(mi)封座(zuo)壓緊螺(luo)母(mu)，輕輕卸下(xia)密(mi)(mi)封座(zuo)并清(qing)洗。

　　隴南機械密封裝配：在(zai)動(dong)、靜(jing)環(huan)鏡(jing)面上(shang)涂一層潔凈的20號潤滑(hua)油(you)，導軸(zhou)承座(zuo)也抹上(shang)潤滑(hua)油(you)，先把靜(jing)環(huan)輕(qing)輕(qing)定(ding)位裝入導軸(zhou)承座(zuo)，再在(zai)泵軸(zhou)上(shang)抹上(shang)潤滑(hua)油(you)，把動(dong)環(huan)部(bu)(bu)分輕(qing)輕(qing)裝入泵軸(zhou)上(shang)，用手(shou)輕(qing)推密封環(huan)應能伸縮(suo)自如，注意動(dong)、靜(jing)環(huan)部(bu)(bu)分的防轉部(bu)(bu)位需裝配到位。

　　裝(zhuang)(zhuang)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)：在(zai)電機軸(zhou)頭上(shang)(shang)(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)(shang)(shang)擋圈，裝(zhuang)(zhuang)上(shang)(shang)(shang)(shang)一半聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)，再在(zai)泵軸(zhou)端和聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)槽內裝(zhuang)(zhuang)上(shang)(shang)(shang)(shang)擋塊(kuai)并(bing)用梅(mei)花扳手(shou)擰緊螺栓；再裝(zhuang)(zhuang)上(shang)(shang)(shang)(shang)另一半聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)擰上(shang)(shang)(shang)(shang)內六角螺釘。安(an)裝(zhuang)(zhuang)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)正確的檢(jian)(jian)查要(yao)求：對分式(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)上(shang)(shang)(shang)(shang)下間隙(xi)需要(yao)均勻(yun)，用手(shou)盤動(dong)(dong)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)幾圈檢(jian)(jian)查轉動(dong)(dong)的靈活(huo)性(xing)。

　　裝(zhuang)密(mi)封(feng)座(zuo)(zuo)：先將密(mi)封(feng)座(zuo)(zuo)裝(zhuang)入(ru)橡膠油封(feng)，再把密(mi)封(feng)座(zuo)(zuo)裝(zhuang)入(ru)泵(beng)蓋并壓(ya)(ya)(ya)(ya)在軸承(cheng)座(zuo)(zuo)上，擰緊螺母(mu)，確保(bao)所有安裝(zhuang)螺釘(ding)(ding)緊固(gu)。當安裝(zhuang)螺釘(ding)(ding)被用(yong)作密(mi)封(feng)與軸之間(jian)的驅動時(shi)(shi)，軸應(ying)打埋頭孔來加固(gu)連接，緊固(gu)壓(ya)(ya)(ya)(ya)蓋螺栓時(shi)(shi)應(ying)該平穩緊固(gu)，并且不要使壓(ya)(ya)(ya)(ya)蓋受彈力。在可能的地方使用(yong)4個以上螺釘(ding)(ding)的等間(jian)距壓(ya)(ya)(ya)(ya)蓋，緊固(gu)壓(ya)(ya)(ya)(ya)蓋螺栓時(shi)(shi)，用(yong)塞尺檢查(cha)軸與壓(ya)(ya)(ya)(ya)蓋之間(jian)的間(jian)隙，這在密(mi)封(feng)腔對壓(ya)(ya)(ya)(ya)蓋不導向時(shi)(shi)，顯得特別(bie)重(zhong)要，因為壓(ya)(ya)(ya)(ya)蓋必須對中。
