　　傳動形式多，但是長嶺機械密封的(de)更換工作(zuo)大同小(xiao)異，首先拆前需確認電機處(chu)于檢(jian)修狀態，擰(ning)下加(jia)油螺塞，用吸管把密封座(zuo)腔(qiang)內的(de)潤(run)滑油吸出。準備好放置泵(beng)(beng)零(ling)件的(de)工作(zuo)臺及拆裝(zhuang)工具，切勿任意亂放亂用，避免碰壞泵(beng)(beng)的(de)零(ling)部(bu)件。

　　拆(chai)對分式聯(lian)軸(zhou)(zhou)器(qi)：先把聯(lian)軸(zhou)(zhou)器(qi)的固定(ding)內(nei)六角螺釘(ding)擰下(xia)來，再輕輕把聯(lian)軸(zhou)(zhou)器(qi)的一半(ban)從(cong)軸(zhou)(zhou)上慢(man)(man)慢(man)(man)拉下(xia)，注意不要掉(diao)了(le)，再用梅花扳手擰下(xia)泵軸(zhou)(zhou)吊(diao)緊螺栓和擋塊，讓葉輪慢(man)(man)慢(man)(man)下(xia)沉至(zhi)泵體，然后拆(chai)下(xia)另外(wai)一半(ban)聯(lian)軸(zhou)(zhou)器(qi)，拿下(xia)泵軸(zhou)(zhou)擋圈。

　　拆卸長嶺機械密封：抓住密(mi)封彈簧順著泵軸(zhou)往上提，就(jiu)能拆下來了。

　　拆卸并清(qing)洗軸承(cheng)座：先(xian)輕輕松動一下軸承(cheng)座后用(yong)拆卸螺栓頂起(qi)軸承(cheng)座，并且沿(yan)著(zhu)泵軸往上提(ti)而卸下，再用(yong)噴氣燃料(liao)清(qing)洗軸承(cheng)及座，裝前(qian)晾干并涂抹少許20號機械(xie)油用(yong)來(lai)潤(run)滑保護(hu)。

　　拆密封座：擰下密封座壓(ya)緊螺母，輕輕卸下密封座并清洗。

　　長嶺機械密封裝(zhuang)(zhuang)配：在動、靜(jing)(jing)環(huan)鏡面上(shang)(shang)涂一層潔凈的(de)20號潤(run)滑(hua)油，導(dao)軸承座也(ye)抹上(shang)(shang)潤(run)滑(hua)油，先把靜(jing)(jing)環(huan)輕輕定位(wei)(wei)裝(zhuang)(zhuang)入導(dao)軸承座，再在泵(beng)軸上(shang)(shang)抹上(shang)(shang)潤(run)滑(hua)油，把動環(huan)部分(fen)輕輕裝(zhuang)(zhuang)入泵(beng)軸上(shang)(shang)，用手輕推密封(feng)環(huan)應能(neng)伸縮自如，注意動、靜(jing)(jing)環(huan)部分(fen)的(de)防轉部位(wei)(wei)需(xu)裝(zhuang)(zhuang)配到位(wei)(wei)。

　　裝聯(lian)軸(zhou)(zhou)(zhou)器：在電機軸(zhou)(zhou)(zhou)頭上(shang)(shang)裝上(shang)(shang)擋圈，裝上(shang)(shang)一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器，再(zai)在泵軸(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)器槽內(nei)(nei)裝上(shang)(shang)擋塊并用(yong)梅花(hua)扳手(shou)擰緊螺栓；再(zai)裝上(shang)(shang)另一(yi)半聯(lian)軸(zhou)(zhou)(zhou)器擰上(shang)(shang)內(nei)(nei)六角(jiao)螺釘。安裝聯(lian)軸(zhou)(zhou)(zhou)器正(zheng)確的(de)檢(jian)查要(yao)求：對分(fen)式聯(lian)軸(zhou)(zhou)(zhou)器上(shang)(shang)下間(jian)隙(xi)需要(yao)均勻，用(yong)手(shou)盤動(dong)聯(lian)軸(zhou)(zhou)(zhou)器幾(ji)圈檢(jian)查轉(zhuan)動(dong)的(de)靈活性(xing)。

　　裝(zhuang)密(mi)封(feng)座(zuo)：先將密(mi)封(feng)座(zuo)裝(zhuang)入橡膠油封(feng)，再把密(mi)封(feng)座(zuo)裝(zhuang)入泵蓋(gai)并壓(ya)(ya)(ya)在軸(zhou)承座(zuo)上(shang)，擰緊(jin)螺母(mu)，確保(bao)所有(you)安(an)裝(zhuang)螺釘(ding)緊(jin)固。當(dang)安(an)裝(zhuang)螺釘(ding)被用(yong)作密(mi)封(feng)與(yu)軸(zhou)之間(jian)的驅動時(shi)，軸(zhou)應(ying)打埋頭(tou)孔來加固連接，緊(jin)固壓(ya)(ya)(ya)蓋(gai)螺栓時(shi)應(ying)該平穩(wen)緊(jin)固，并且不要使壓(ya)(ya)(ya)蓋(gai)受彈力(li)。在可(ke)能的地方使用(yong)4個以(yi)上(shang)螺釘(ding)的等間(jian)距壓(ya)(ya)(ya)蓋(gai)，緊(jin)固壓(ya)(ya)(ya)蓋(gai)螺栓時(shi)，用(yong)塞尺檢(jian)查(cha)軸(zhou)與(yu)壓(ya)(ya)(ya)蓋(gai)之間(jian)的間(jian)隙，這在密(mi)封(feng)腔對壓(ya)(ya)(ya)蓋(gai)不導向時(shi)，顯得特別重(zhong)要，因(yin)為(wei)壓(ya)(ya)(ya)蓋(gai)必須對中(zhong)。
