　　傳動形式多，但是寧江機械密封的(de)更換(huan)工作大同(tong)小異，首(shou)先拆(chai)前需確認電機(ji)處于檢修狀(zhuang)態(tai)，擰下加油螺塞，用吸管把密封座腔內的(de)潤滑油吸出。準備好放置(zhi)泵零件的(de)工作臺及拆(chai)裝(zhuang)工具，切勿任意亂放亂用，避(bi)免碰壞泵的(de)零部件。

　　拆(chai)對分式聯軸(zhou)(zhou)(zhou)器：先把聯軸(zhou)(zhou)(zhou)器的(de)固定內六角螺釘擰下來，再輕輕把聯軸(zhou)(zhou)(zhou)器的(de)一半從軸(zhou)(zhou)(zhou)上慢(man)慢(man)拉(la)下，注意不(bu)要掉(diao)了，再用梅花扳手擰下泵軸(zhou)(zhou)(zhou)吊緊(jin)螺栓(shuan)和擋(dang)塊(kuai)，讓葉輪慢(man)慢(man)下沉至泵體，然(ran)后(hou)拆(chai)下另外一半聯軸(zhou)(zhou)(zhou)器，拿下泵軸(zhou)(zhou)(zhou)擋(dang)圈。

　　拆卸寧江機械密封：抓住(zhu)密封(feng)彈(dan)簧順著泵(beng)軸往(wang)上提，就能拆下來了。

　　拆卸(xie)并清洗(xi)軸(zhou)(zhou)承座：先輕輕松動一(yi)下軸(zhou)(zhou)承座后用拆卸(xie)螺(luo)栓頂(ding)起軸(zhou)(zhou)承座，并且沿著泵軸(zhou)(zhou)往上(shang)提而卸(xie)下，再用噴氣燃(ran)料清洗(xi)軸(zhou)(zhou)承及座，裝前晾干(gan)并涂抹(mo)少許20號機械油(you)用來潤滑保護。

　　拆密(mi)封(feng)座：擰下(xia)密(mi)封(feng)座壓緊螺母，輕(qing)輕(qing)卸下(xia)密(mi)封(feng)座并清洗。

　　寧江機械密封裝(zhuang)配：在動(dong)、靜環(huan)(huan)鏡面上(shang)(shang)(shang)(shang)涂(tu)一(yi)層潔凈(jing)的(de)20號潤滑油，導軸(zhou)(zhou)承座(zuo)也抹上(shang)(shang)(shang)(shang)潤滑油，先把靜環(huan)(huan)輕(qing)(qing)輕(qing)(qing)定位(wei)裝(zhuang)入導軸(zhou)(zhou)承座(zuo)，再在泵軸(zhou)(zhou)上(shang)(shang)(shang)(shang)抹上(shang)(shang)(shang)(shang)潤滑油，把動(dong)環(huan)(huan)部分輕(qing)(qing)輕(qing)(qing)裝(zhuang)入泵軸(zhou)(zhou)上(shang)(shang)(shang)(shang)，用手輕(qing)(qing)推密封環(huan)(huan)應能伸縮自如(ru)，注意(yi)動(dong)、靜環(huan)(huan)部分的(de)防轉部位(wei)需裝(zhuang)配到位(wei)。

　　裝(zhuang)(zhuang)(zhuang)聯軸(zhou)器(qi)(qi)：在電機軸(zhou)頭上(shang)裝(zhuang)(zhuang)(zhuang)上(shang)擋(dang)圈，裝(zhuang)(zhuang)(zhuang)上(shang)一半聯軸(zhou)器(qi)(qi)，再在泵軸(zhou)端和聯軸(zhou)器(qi)(qi)槽內裝(zhuang)(zhuang)(zhuang)上(shang)擋(dang)塊并用梅(mei)花扳(ban)手(shou)擰緊(jin)螺(luo)栓(shuan)；再裝(zhuang)(zhuang)(zhuang)上(shang)另一半聯軸(zhou)器(qi)(qi)擰上(shang)內六(liu)角螺(luo)釘。安裝(zhuang)(zhuang)(zhuang)聯軸(zhou)器(qi)(qi)正確的檢(jian)查要(yao)求：對(dui)分(fen)式聯軸(zhou)器(qi)(qi)上(shang)下間隙(xi)需(xu)要(yao)均勻，用手(shou)盤(pan)動聯軸(zhou)器(qi)(qi)幾圈檢(jian)查轉動的靈活性。

　　裝(zhuang)(zhuang)密(mi)封(feng)座：先將密(mi)封(feng)座裝(zhuang)(zhuang)入(ru)橡膠油(you)封(feng)，再把密(mi)封(feng)座裝(zhuang)(zhuang)入(ru)泵蓋(gai)(gai)(gai)(gai)并壓(ya)(ya)(ya)在軸(zhou)承座上(shang)，擰緊螺母，確保所有安裝(zhuang)(zhuang)螺釘(ding)緊固。當(dang)安裝(zhuang)(zhuang)螺釘(ding)被用(yong)作密(mi)封(feng)與軸(zhou)之(zhi)間(jian)(jian)的(de)(de)驅動時，軸(zhou)應打(da)埋頭孔來加固連接，緊固壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)螺栓(shuan)時應該平穩緊固，并且(qie)不要(yao)使(shi)壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)受(shou)彈力。在可能的(de)(de)地方使(shi)用(yong)4個以上(shang)螺釘(ding)的(de)(de)等間(jian)(jian)距壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)，緊固壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)螺栓(shuan)時，用(yong)塞尺檢查軸(zhou)與壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)之(zhi)間(jian)(jian)的(de)(de)間(jian)(jian)隙，這在密(mi)封(feng)腔對壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)不導向(xiang)時，顯得特別重要(yao)，因為壓(ya)(ya)(ya)蓋(gai)(gai)(gai)(gai)必須對中。
