　　傳動形式多，但是紅毛鎮機械密封的(de)更(geng)換工作大同小異，首先拆前需確(que)認(ren)電機處(chu)于檢(jian)修(xiu)狀態，擰下(xia)加油螺塞，用(yong)(yong)吸管把密封座腔(qiang)內的(de)潤滑油吸出(chu)。準備好放置泵(beng)零件的(de)工作臺及(ji)拆裝工具(ju)，切勿任(ren)意亂放亂用(yong)(yong)，避免(mian)碰壞泵(beng)的(de)零部(bu)件。

　　拆對分式聯軸器(qi)：先把(ba)聯軸器(qi)的(de)固定內六角(jiao)螺釘(ding)擰(ning)下(xia)來，再輕輕把(ba)聯軸器(qi)的(de)一半(ban)從軸上慢(man)(man)(man)慢(man)(man)(man)拉下(xia)，注意不要掉了，再用梅花扳手擰(ning)下(xia)泵(beng)軸吊緊螺栓和擋塊，讓葉輪慢(man)(man)(man)慢(man)(man)(man)下(xia)沉(chen)至泵(beng)體，然后拆下(xia)另外一半(ban)聯軸器(qi)，拿下(xia)泵(beng)軸擋圈。

　　拆卸紅毛鎮機械密封：抓住密封彈簧順著(zhu)泵(beng)軸往上提(ti)，就能拆(chai)下來了。

　　拆(chai)卸(xie)(xie)并(bing)清洗軸承(cheng)座(zuo)：先(xian)輕輕松(song)動一下(xia)軸承(cheng)座(zuo)后用(yong)拆(chai)卸(xie)(xie)螺栓頂(ding)起軸承(cheng)座(zuo)，并(bing)且沿著泵(beng)軸往上提而卸(xie)(xie)下(xia)，再(zai)用(yong)噴氣燃料(liao)清洗軸承(cheng)及座(zuo)，裝前晾干并(bing)涂(tu)抹少許20號機械油(you)用(yong)來潤滑保護。

　　拆密(mi)(mi)封座(zuo)(zuo)：擰下密(mi)(mi)封座(zuo)(zuo)壓緊(jin)螺(luo)母，輕輕卸下密(mi)(mi)封座(zuo)(zuo)并清洗。

　　紅毛鎮機械密封裝(zhuang)配(pei)：在動(dong)、靜(jing)環(huan)(huan)(huan)鏡面上涂一層潔凈(jing)的20號(hao)潤(run)滑(hua)油，導軸(zhou)(zhou)(zhou)承座也抹(mo)上潤(run)滑(hua)油，先把(ba)靜(jing)環(huan)(huan)(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)入導軸(zhou)(zhou)(zhou)承座，再在泵(beng)軸(zhou)(zhou)(zhou)上抹(mo)上潤(run)滑(hua)油，把(ba)動(dong)環(huan)(huan)(huan)部分輕(qing)輕(qing)裝(zhuang)入泵(beng)軸(zhou)(zhou)(zhou)上，用手輕(qing)推密(mi)封(feng)環(huan)(huan)(huan)應能伸(shen)縮(suo)自如，注意動(dong)、靜(jing)環(huan)(huan)(huan)部分的防轉部位(wei)需(xu)裝(zhuang)配(pei)到(dao)位(wei)。

　　裝聯(lian)軸(zhou)(zhou)器(qi)(qi)：在電機軸(zhou)(zhou)頭上(shang)裝上(shang)擋圈，裝上(shang)一半(ban)聯(lian)軸(zhou)(zhou)器(qi)(qi)，再(zai)在泵(beng)軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)(qi)槽內(nei)裝上(shang)擋塊并(bing)用梅花扳手(shou)擰緊螺栓；再(zai)裝上(shang)另一半(ban)聯(lian)軸(zhou)(zhou)器(qi)(qi)擰上(shang)內(nei)六角螺釘。安裝聯(lian)軸(zhou)(zhou)器(qi)(qi)正確的(de)檢查要(yao)求(qiu)：對分式(shi)聯(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)下間隙需要(yao)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(zhuang)密封(feng)座(zuo)：先將(jiang)密封(feng)座(zuo)裝(zhuang)入橡膠油封(feng)，再(zai)把密封(feng)座(zuo)裝(zhuang)入泵蓋(gai)并(bing)壓(ya)(ya)在軸承座(zuo)上，擰緊(jin)(jin)(jin)螺(luo)母，確(que)保所有(you)安裝(zhuang)螺(luo)釘(ding)(ding)(ding)緊(jin)(jin)(jin)固。當安裝(zhuang)螺(luo)釘(ding)(ding)(ding)被(bei)用作密封(feng)與(yu)軸之間(jian)的(de)(de)驅動時(shi)，軸應打埋頭孔來加固連接，緊(jin)(jin)(jin)固壓(ya)(ya)蓋(gai)螺(luo)栓時(shi)應該平(ping)穩(wen)緊(jin)(jin)(jin)固，并(bing)且不要(yao)使(shi)壓(ya)(ya)蓋(gai)受彈(dan)力。在可能的(de)(de)地方使(shi)用4個以上螺(luo)釘(ding)(ding)(ding)的(de)(de)等間(jian)距壓(ya)(ya)蓋(gai)，緊(jin)(jin)(jin)固壓(ya)(ya)蓋(gai)螺(luo)栓時(shi)，用塞尺檢(jian)查軸與(yu)壓(ya)(ya)蓋(gai)之間(jian)的(de)(de)間(jian)隙(xi)，這在密封(feng)腔對壓(ya)(ya)蓋(gai)不導向時(shi)，顯得特別(bie)重要(yao)，因(yin)為壓(ya)(ya)蓋(gai)必(bi)須(xu)對中。
