　　傳動形式多，但是申扎機械密封的(de)(de)(de)更換工(gong)作大同小異，首先拆(chai)前需確認電機處于檢(jian)修狀態(tai)，擰下加油(you)螺塞，用(yong)吸管把密(mi)封(feng)座(zuo)腔(qiang)內的(de)(de)(de)潤滑油(you)吸出。準備好(hao)放置泵(beng)零件(jian)的(de)(de)(de)工(gong)作臺及拆(chai)裝(zhuang)工(gong)具，切(qie)勿任意亂(luan)放亂(luan)用(yong)，避免碰壞泵(beng)的(de)(de)(de)零部件(jian)。

　　拆(chai)對(dui)分式聯(lian)軸(zhou)(zhou)(zhou)器：先(xian)把(ba)聯(lian)軸(zhou)(zhou)(zhou)器的(de)固定內六(liu)角螺釘擰下(xia)來，再輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)(zhou)(zhou)器的(de)一(yi)半從軸(zhou)(zhou)(zhou)上慢(man)慢(man)拉下(xia)，注意不(bu)要(yao)掉了，再用梅(mei)花扳(ban)手擰下(xia)泵(beng)軸(zhou)(zhou)(zhou)吊緊螺栓(shuan)和擋塊，讓葉輪慢(man)慢(man)下(xia)沉至泵(beng)體，然(ran)后拆(chai)下(xia)另(ling)外一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器，拿下(xia)泵(beng)軸(zhou)(zhou)(zhou)擋圈。

　　拆卸申扎機械密封：抓住密(mi)封彈簧順(shun)著泵軸往(wang)上提，就(jiu)能拆下(xia)來了。

　　拆(chai)卸并清(qing)洗軸(zhou)承座(zuo)：先輕輕松動一下(xia)軸(zhou)承座(zuo)后(hou)用(yong)拆(chai)卸螺栓頂起軸(zhou)承座(zuo)，并且沿著泵軸(zhou)往上提而卸下(xia)，再(zai)用(yong)噴氣燃料清(qing)洗軸(zhou)承及座(zuo)，裝前晾干并涂抹少許20號機械(xie)油用(yong)來潤滑保(bao)護。

　　拆密封(feng)座(zuo)：擰下密封(feng)座(zuo)壓(ya)緊螺(luo)母，輕輕卸下密封(feng)座(zuo)并清洗。

　　申扎機械密封裝配：在(zai)動、靜環鏡面上(shang)(shang)涂(tu)一層潔(jie)凈的(de)20號(hao)潤滑(hua)油(you)，導(dao)軸(zhou)承(cheng)座(zuo)也抹(mo)上(shang)(shang)潤滑(hua)油(you)，先把(ba)靜環輕(qing)輕(qing)定位(wei)裝入導(dao)軸(zhou)承(cheng)座(zuo)，再在(zai)泵軸(zhou)上(shang)(shang)抹(mo)上(shang)(shang)潤滑(hua)油(you)，把(ba)動環部分(fen)輕(qing)輕(qing)裝入泵軸(zhou)上(shang)(shang)，用手輕(qing)推密封(feng)環應能伸(shen)縮自如，注意動、靜環部分(fen)的(de)防轉部位(wei)需裝配到位(wei)。

　　裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)：在電機軸(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈，裝(zhuang)上(shang)一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)槽內裝(zhuang)上(shang)擋塊并用梅花扳手擰緊螺栓(shuan)；再裝(zhuang)上(shang)另一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)擰上(shang)內六角螺釘。安裝(zhuang)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)正(zheng)確的(de)檢(jian)查(cha)要(yao)求：對(dui)分(fen)式聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)下間隙需要(yao)均(jun)勻，用手盤動聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)幾圈檢(jian)查(cha)轉動的(de)靈(ling)活性。

　　裝(zhuang)密(mi)封座：先(xian)將密(mi)封座裝(zhuang)入橡膠油封，再把(ba)密(mi)封座裝(zhuang)入泵蓋(gai)并壓(ya)(ya)(ya)在(zai)軸承座上(shang)，擰緊螺(luo)(luo)母(mu)，確保所有安裝(zhuang)螺(luo)(luo)釘緊固(gu)(gu)。當(dang)安裝(zhuang)螺(luo)(luo)釘被用(yong)作密(mi)封與(yu)軸之(zhi)間的(de)(de)驅動(dong)時，軸應打埋(mai)頭孔來加(jia)固(gu)(gu)連接，緊固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)(luo)栓時應該(gai)平穩緊固(gu)(gu)，并且不(bu)要(yao)使壓(ya)(ya)(ya)蓋(gai)受(shou)彈力。在(zai)可能的(de)(de)地方使用(yong)4個以上(shang)螺(luo)(luo)釘的(de)(de)等間距壓(ya)(ya)(ya)蓋(gai)，緊固(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)(luo)栓時，用(yong)塞尺檢查軸與(yu)壓(ya)(ya)(ya)蓋(gai)之(zhi)間的(de)(de)間隙，這在(zai)密(mi)封腔對壓(ya)(ya)(ya)蓋(gai)不(bu)導向時，顯得特(te)別重要(yao)，因為壓(ya)(ya)(ya)蓋(gai)必須對中。
