　　傳動形式多，但是龍安機械密封的(de)更換(huan)工(gong)作(zuo)大(da)同(tong)小異(yi)，首先拆前需確認電機處于(yu)檢修狀態，擰(ning)下加油(you)螺(luo)塞，用吸管(guan)把(ba)密封座腔內的(de)潤滑油(you)吸出。準備好(hao)放置泵零件(jian)的(de)工(gong)作(zuo)臺及拆裝工(gong)具(ju)，切勿任(ren)意亂放亂用，避免(mian)碰壞泵的(de)零部(bu)件(jian)。

　　拆對分式(shi)聯(lian)(lian)軸器(qi)(qi)：先把聯(lian)(lian)軸器(qi)(qi)的固定內(nei)六角(jiao)螺釘擰下(xia)來，再(zai)輕(qing)(qing)輕(qing)(qing)把聯(lian)(lian)軸器(qi)(qi)的一半(ban)從軸上(shang)慢(man)慢(man)拉下(xia)，注意(yi)不要(yao)掉了，再(zai)用梅花扳手擰下(xia)泵軸吊緊螺栓和(he)擋塊，讓葉輪慢(man)慢(man)下(xia)沉至泵體，然后(hou)拆下(xia)另(ling)外一半(ban)聯(lian)(lian)軸器(qi)(qi)，拿下(xia)泵軸擋圈(quan)。

　　拆卸龍安機械密封：抓住密(mi)封(feng)彈簧(huang)順著(zhu)泵軸往(wang)上提(ti)，就能拆下來(lai)了。

　　拆(chai)卸并(bing)清洗軸承(cheng)座(zuo)：先輕輕松(song)動一下軸承(cheng)座(zuo)后(hou)用(yong)拆(chai)卸螺(luo)栓頂(ding)起軸承(cheng)座(zuo)，并(bing)且沿著泵(beng)軸往上提而卸下，再(zai)用(yong)噴氣燃料清洗軸承(cheng)及(ji)座(zuo)，裝前晾干并(bing)涂抹少許(xu)20號機械油(you)用(yong)來潤滑保護。

　　拆(chai)密封座：擰下密封座壓緊(jin)螺母，輕輕卸下密封座并清洗。

　　龍安機械密封裝配(pei)：在(zai)動、靜環(huan)鏡面上(shang)涂一層潔(jie)凈(jing)的20號潤滑油(you)(you)，導軸承座(zuo)也抹(mo)上(shang)潤滑油(you)(you)，先把(ba)靜環(huan)輕(qing)輕(qing)定位裝入導軸承座(zuo)，再在(zai)泵軸上(shang)抹(mo)上(shang)潤滑油(you)(you)，把(ba)動環(huan)部分輕(qing)輕(qing)裝入泵軸上(shang)，用手輕(qing)推密封環(huan)應能伸縮(suo)自如，注意動、靜環(huan)部分的防轉部位需裝配(pei)到位。

　　裝(zhuang)(zhuang)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)(shang)(shang)擋圈(quan)，裝(zhuang)(zhuang)上(shang)(shang)(shang)(shang)一(yi)半聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)，再在泵(beng)軸(zhou)(zhou)(zhou)端(duan)和聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)槽(cao)內(nei)裝(zhuang)(zhuang)上(shang)(shang)(shang)(shang)擋塊(kuai)并用梅(mei)花扳手擰緊(jin)螺栓；再裝(zhuang)(zhuang)上(shang)(shang)(shang)(shang)另(ling)一(yi)半聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)擰上(shang)(shang)(shang)(shang)內(nei)六(liu)角螺釘。安裝(zhuang)(zhuang)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)正確的(de)(de)檢查要求：對分式(shi)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)上(shang)(shang)(shang)(shang)下(xia)間隙需要均勻(yun)，用手盤動聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)幾圈(quan)檢查轉動的(de)(de)靈活性。

　　裝密(mi)(mi)封(feng)座：先將密(mi)(mi)封(feng)座裝入(ru)橡膠油封(feng)，再把密(mi)(mi)封(feng)座裝入(ru)泵蓋(gai)(gai)并(bing)壓(ya)(ya)(ya)在軸(zhou)(zhou)承座上(shang)，擰緊螺(luo)母，確保(bao)所有安(an)(an)裝螺(luo)釘緊固。當安(an)(an)裝螺(luo)釘被用(yong)作密(mi)(mi)封(feng)與軸(zhou)(zhou)之(zhi)間(jian)的(de)驅動時，軸(zhou)(zhou)應打埋頭孔來加固連接，緊固壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時應該平(ping)穩緊固，并(bing)且(qie)不(bu)(bu)要使壓(ya)(ya)(ya)蓋(gai)(gai)受彈力(li)。在可(ke)能的(de)地方使用(yong)4個以上(shang)螺(luo)釘的(de)等間(jian)距(ju)壓(ya)(ya)(ya)蓋(gai)(gai)，緊固壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時，用(yong)塞尺(chi)檢查軸(zhou)(zhou)與壓(ya)(ya)(ya)蓋(gai)(gai)之(zhi)間(jian)的(de)間(jian)隙(xi)，這在密(mi)(mi)封(feng)腔(qiang)對(dui)壓(ya)(ya)(ya)蓋(gai)(gai)不(bu)(bu)導(dao)向(xiang)時，顯得(de)特別(bie)重要，因為壓(ya)(ya)(ya)蓋(gai)(gai)必(bi)須對(dui)中。
