　　傳動形式多，但是和政機械密封的更換工作大同(tong)小異，首先拆前需確認電機處于檢(jian)修狀態，擰下加(jia)油螺塞(sai)，用吸管把密(mi)封座腔內(nei)的潤滑(hua)油吸出。準備好(hao)放置泵(beng)零件的工作臺及(ji)拆裝(zhuang)工具(ju)，切勿任意亂放亂用，避(bi)免碰壞泵(beng)的零部件。

　　拆(chai)對分式(shi)聯(lian)軸(zhou)(zhou)(zhou)器(qi)：先把(ba)聯(lian)軸(zhou)(zhou)(zhou)器(qi)的(de)固(gu)定內六(liu)角(jiao)螺(luo)釘擰下(xia)(xia)來(lai)，再(zai)(zai)輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)(zhou)(zhou)器(qi)的(de)一(yi)半從軸(zhou)(zhou)(zhou)上慢(man)慢(man)拉下(xia)(xia)，注意不要掉(diao)了(le)，再(zai)(zai)用梅花扳手擰下(xia)(xia)泵軸(zhou)(zhou)(zhou)吊緊螺(luo)栓和擋塊，讓葉(xie)輪(lun)慢(man)慢(man)下(xia)(xia)沉至(zhi)泵體(ti)，然后拆(chai)下(xia)(xia)另外(wai)一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器(qi)，拿下(xia)(xia)泵軸(zhou)(zhou)(zhou)擋圈。

　　拆卸和政機械密封：抓(zhua)住密封彈簧順著泵軸往上提，就能拆(chai)下(xia)來了。

　　拆(chai)卸(xie)并清(qing)洗(xi)軸(zhou)承(cheng)座(zuo)：先輕(qing)輕(qing)松(song)動一(yi)下軸(zhou)承(cheng)座(zuo)后用(yong)拆(chai)卸(xie)螺(luo)栓頂(ding)起(qi)軸(zhou)承(cheng)座(zuo)，并且沿著泵軸(zhou)往上(shang)提而卸(xie)下，再用(yong)噴氣燃(ran)料清(qing)洗(xi)軸(zhou)承(cheng)及(ji)座(zuo)，裝(zhuang)前晾干并涂抹少(shao)許20號機械油用(yong)來潤滑保護。

　　拆密(mi)(mi)封(feng)座：擰下密(mi)(mi)封(feng)座壓(ya)緊螺母，輕輕卸(xie)下密(mi)(mi)封(feng)座并(bing)清洗。

　　和政機械密封裝配(pei)：在動(dong)、靜(jing)環鏡面上(shang)涂(tu)一層潔凈(jing)的(de)20號潤(run)滑油(you)，導(dao)軸(zhou)(zhou)承座也抹(mo)上(shang)潤(run)滑油(you)，先把靜(jing)環輕(qing)輕(qing)定位裝入(ru)導(dao)軸(zhou)(zhou)承座，再在泵軸(zhou)(zhou)上(shang)抹(mo)上(shang)潤(run)滑油(you)，把動(dong)環部(bu)分(fen)輕(qing)輕(qing)裝入(ru)泵軸(zhou)(zhou)上(shang)，用手輕(qing)推密封環應能伸縮(suo)自如，注意動(dong)、靜(jing)環部(bu)分(fen)的(de)防轉部(bu)位需(xu)裝配(pei)到位。

　　裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)：在電機軸(zhou)頭上(shang)(shang)(shang)裝(zhuang)上(shang)(shang)(shang)擋圈，裝(zhuang)上(shang)(shang)(shang)一半(ban)聯(lian)(lian)軸(zhou)器(qi)，再(zai)在泵軸(zhou)端和聯(lian)(lian)軸(zhou)器(qi)槽內裝(zhuang)上(shang)(shang)(shang)擋塊并用(yong)梅(mei)花扳手(shou)擰緊(jin)螺栓；再(zai)裝(zhuang)上(shang)(shang)(shang)另一半(ban)聯(lian)(lian)軸(zhou)器(qi)擰上(shang)(shang)(shang)內六角螺釘。安裝(zhuang)聯(lian)(lian)軸(zhou)器(qi)正確的(de)檢查(cha)要(yao)(yao)求(qiu)：對分式聯(lian)(lian)軸(zhou)器(qi)上(shang)(shang)(shang)下間隙需要(yao)(yao)均勻，用(yong)手(shou)盤(pan)動聯(lian)(lian)軸(zhou)器(qi)幾圈檢查(cha)轉動的(de)靈活(huo)性(xing)。

　　裝密(mi)封(feng)(feng)座(zuo)：先將密(mi)封(feng)(feng)座(zuo)裝入(ru)橡(xiang)膠油封(feng)(feng)，再把密(mi)封(feng)(feng)座(zuo)裝入(ru)泵蓋(gai)并壓(ya)(ya)在(zai)軸(zhou)承座(zuo)上，擰緊螺(luo)母(mu)，確(que)保所有安裝螺(luo)釘(ding)(ding)緊固(gu)(gu)(gu)。當安裝螺(luo)釘(ding)(ding)被用作(zuo)密(mi)封(feng)(feng)與軸(zhou)之間的驅動時，軸(zhou)應打埋(mai)頭孔來加固(gu)(gu)(gu)連(lian)接(jie)，緊固(gu)(gu)(gu)壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時應該平穩緊固(gu)(gu)(gu)，并且不要使壓(ya)(ya)蓋(gai)受彈力(li)。在(zai)可能的地(di)方(fang)使用4個(ge)以上螺(luo)釘(ding)(ding)的等間距(ju)壓(ya)(ya)蓋(gai)，緊固(gu)(gu)(gu)壓(ya)(ya)蓋(gai)螺(luo)栓(shuan)時，用塞尺檢查(cha)軸(zhou)與壓(ya)(ya)蓋(gai)之間的間隙，這在(zai)密(mi)封(feng)(feng)腔對壓(ya)(ya)蓋(gai)不導(dao)向時，顯得特別重要，因為壓(ya)(ya)蓋(gai)必須(xu)對中(zhong)。
