　　傳動形式多，但是阿拉爾農場機械密封的更(geng)換工作大同小異(yi)，首先拆前需確認電(dian)機處于檢修狀態，擰下(xia)加油螺塞(sai)，用吸管(guan)把密封座腔內的潤滑油吸出(chu)。準備好放置(zhi)泵零(ling)件(jian)的工作臺及拆裝工具，切勿任意亂放亂用，避免(mian)碰(peng)壞泵的零(ling)部(bu)件(jian)。

　　拆對分式聯(lian)軸(zhou)(zhou)器(qi)(qi)：先把聯(lian)軸(zhou)(zhou)器(qi)(qi)的(de)固(gu)定內六角螺釘擰(ning)下(xia)來，再(zai)輕(qing)輕(qing)把聯(lian)軸(zhou)(zhou)器(qi)(qi)的(de)一(yi)半從(cong)軸(zhou)(zhou)上慢慢拉下(xia)，注意(yi)不(bu)要掉了(le)，再(zai)用(yong)梅花扳手擰(ning)下(xia)泵(beng)軸(zhou)(zhou)吊緊螺栓和擋塊(kuai)，讓葉輪慢慢下(xia)沉至泵(beng)體，然(ran)后(hou)拆下(xia)另外一(yi)半聯(lian)軸(zhou)(zhou)器(qi)(qi)，拿下(xia)泵(beng)軸(zhou)(zhou)擋圈(quan)。

　　拆卸阿拉爾農場機械密封：抓(zhua)住密封(feng)彈簧(huang)順著(zhu)泵(beng)軸(zhou)往上提，就能拆下來了。

　　拆卸并(bing)清洗(xi)軸承座：先輕(qing)輕(qing)松動一(yi)下軸承座后(hou)用(yong)拆卸螺栓(shuan)頂起軸承座，并(bing)且沿著(zhu)泵軸往(wang)上提而(er)卸下，再用(yong)噴氣燃(ran)料清洗(xi)軸承及座，裝前晾干并(bing)涂抹少許20號機(ji)械油用(yong)來潤滑(hua)保護。

　　拆密封座(zuo)：擰下(xia)密封座(zuo)壓緊(jin)螺母，輕(qing)輕(qing)卸下(xia)密封座(zuo)并清(qing)洗。

　　阿拉爾農場機械密封裝(zhuang)配：在動(dong)、靜(jing)(jing)環(huan)鏡面上涂一層潔凈(jing)的(de)20號潤(run)(run)滑油(you)，導軸(zhou)(zhou)承座也(ye)抹(mo)上潤(run)(run)滑油(you)，先把(ba)靜(jing)(jing)環(huan)輕(qing)(qing)(qing)輕(qing)(qing)(qing)定位(wei)裝(zhuang)入(ru)導軸(zhou)(zhou)承座，再在泵(beng)軸(zhou)(zhou)上抹(mo)上潤(run)(run)滑油(you)，把(ba)動(dong)環(huan)部(bu)(bu)分輕(qing)(qing)(qing)輕(qing)(qing)(qing)裝(zhuang)入(ru)泵(beng)軸(zhou)(zhou)上，用(yong)手輕(qing)(qing)(qing)推(tui)密(mi)封環(huan)應(ying)能伸縮(suo)自(zi)如，注意動(dong)、靜(jing)(jing)環(huan)部(bu)(bu)分的(de)防(fang)轉部(bu)(bu)位(wei)需(xu)裝(zhuang)配到位(wei)。

　　裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)(qi)：在電(dian)機軸(zhou)(zhou)頭上(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)擋(dang)圈，裝(zhuang)(zhuang)上(shang)(shang)一(yi)半(ban)聯(lian)軸(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)(qi)槽(cao)內裝(zhuang)(zhuang)上(shang)(shang)擋(dang)塊(kuai)并(bing)用梅花扳手(shou)擰緊螺栓(shuan)；再裝(zhuang)(zhuang)上(shang)(shang)另一(yi)半(ban)聯(lian)軸(zhou)(zhou)器(qi)(qi)擰上(shang)(shang)內六(liu)角螺釘(ding)。安(an)裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)(qi)正確的(de)檢查要求：對分式聯(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)(shang)下間隙需要均(jun)勻，用手(shou)盤動聯(lian)軸(zhou)(zhou)器(qi)(qi)幾圈檢查轉動的(de)靈活性。

　　裝密(mi)封(feng)(feng)座(zuo)(zuo)：先將密(mi)封(feng)(feng)座(zuo)(zuo)裝入橡(xiang)膠油封(feng)(feng)，再把密(mi)封(feng)(feng)座(zuo)(zuo)裝入泵蓋(gai)(gai)并(bing)(bing)壓(ya)(ya)在軸承(cheng)座(zuo)(zuo)上(shang)，擰緊螺母，確保所(suo)有安裝螺釘(ding)緊固。當安裝螺釘(ding)被用(yong)作密(mi)封(feng)(feng)與軸之間(jian)(jian)的(de)(de)驅動時(shi)，軸應打(da)埋頭孔來加固連接，緊固壓(ya)(ya)蓋(gai)(gai)螺栓時(shi)應該(gai)平穩緊固，并(bing)(bing)且不要使壓(ya)(ya)蓋(gai)(gai)受彈力。在可能的(de)(de)地方使用(yong)4個(ge)以上(shang)螺釘(ding)的(de)(de)等間(jian)(jian)距壓(ya)(ya)蓋(gai)(gai)，緊固壓(ya)(ya)蓋(gai)(gai)螺栓時(shi)，用(yong)塞尺檢查(cha)軸與壓(ya)(ya)蓋(gai)(gai)之間(jian)(jian)的(de)(de)間(jian)(jian)隙，這在密(mi)封(feng)(feng)腔對壓(ya)(ya)蓋(gai)(gai)不導向時(shi)，顯(xian)得特別重要，因為壓(ya)(ya)蓋(gai)(gai)必(bi)須對中。
