　　傳動形式多，但是丹江口機械密封的(de)更換工作大(da)同小(xiao)異，首先(xian)拆前需確(que)認電機處于檢修狀態，擰(ning)下加油螺塞，用(yong)吸管把(ba)密封座腔內(nei)的(de)潤滑油吸出。準備好放置泵(beng)零件(jian)(jian)的(de)工作臺及拆裝(zhuang)工具，切勿任(ren)意亂(luan)(luan)放亂(luan)(luan)用(yong)，避(bi)免碰壞泵(beng)的(de)零部件(jian)(jian)。

　　拆對(dui)分式聯軸(zhou)(zhou)器(qi)：先把聯軸(zhou)(zhou)器(qi)的(de)固定(ding)內六角螺(luo)釘(ding)擰(ning)(ning)下(xia)(xia)來，再(zai)輕輕把聯軸(zhou)(zhou)器(qi)的(de)一(yi)半從軸(zhou)(zhou)上慢慢拉下(xia)(xia)，注(zhu)意不要掉了，再(zai)用梅花扳手擰(ning)(ning)下(xia)(xia)泵軸(zhou)(zhou)吊緊螺(luo)栓和擋(dang)塊，讓葉輪慢慢下(xia)(xia)沉至泵體，然后拆下(xia)(xia)另(ling)外一(yi)半聯軸(zhou)(zhou)器(qi)，拿下(xia)(xia)泵軸(zhou)(zhou)擋(dang)圈。

　　拆卸丹江口機械密封：抓住(zhu)密封彈簧順著泵軸往上(shang)提，就能(neng)拆下來(lai)了。

　　拆(chai)(chai)卸并清洗軸(zhou)承(cheng)座(zuo)(zuo)：先輕(qing)輕(qing)松動(dong)一下軸(zhou)承(cheng)座(zuo)(zuo)后(hou)用拆(chai)(chai)卸螺栓頂(ding)起軸(zhou)承(cheng)座(zuo)(zuo)，并且沿著泵軸(zhou)往上提而(er)卸下，再用噴氣燃料清洗軸(zhou)承(cheng)及座(zuo)(zuo)，裝前晾干并涂抹少許20號(hao)機械油用來(lai)潤(run)滑保護。

　　拆(chai)密(mi)封座(zuo)：擰下密(mi)封座(zuo)壓緊(jin)螺母，輕輕卸下密(mi)封座(zuo)并清(qing)洗。

　　丹江口機械密封裝配(pei)：在(zai)動、靜環(huan)(huan)(huan)鏡面上(shang)涂一(yi)層潔凈(jing)的20號潤(run)滑(hua)(hua)油(you)，導軸承座(zuo)也抹上(shang)潤(run)滑(hua)(hua)油(you)，先(xian)把(ba)靜環(huan)(huan)(huan)輕(qing)輕(qing)定位(wei)裝入(ru)導軸承座(zuo)，再在(zai)泵軸上(shang)抹上(shang)潤(run)滑(hua)(hua)油(you)，把(ba)動環(huan)(huan)(huan)部分輕(qing)輕(qing)裝入(ru)泵軸上(shang)，用手輕(qing)推密封環(huan)(huan)(huan)應能伸縮自(zi)如，注意動、靜環(huan)(huan)(huan)部分的防(fang)轉(zhuan)部位(wei)需裝配(pei)到位(wei)。

　　裝聯(lian)軸(zhou)(zhou)器(qi)(qi)：在(zai)電(dian)機(ji)軸(zhou)(zhou)頭上(shang)裝上(shang)擋(dang)圈(quan)，裝上(shang)一半聯(lian)軸(zhou)(zhou)器(qi)(qi)，再在(zai)泵軸(zhou)(zhou)端和(he)聯(lian)軸(zhou)(zhou)器(qi)(qi)槽內裝上(shang)擋(dang)塊并用梅(mei)花扳手擰緊螺(luo)栓；再裝上(shang)另一半聯(lian)軸(zhou)(zhou)器(qi)(qi)擰上(shang)內六角螺(luo)釘。安(an)裝聯(lian)軸(zhou)(zhou)器(qi)(qi)正確的(de)檢查要(yao)求(qiu)：對分式聯(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)下間(jian)隙(xi)需要(yao)均勻(yun)，用手盤動(dong)聯(lian)軸(zhou)(zhou)器(qi)(qi)幾圈(quan)檢查轉(zhuan)動(dong)的(de)靈活性。

　　裝(zhuang)密(mi)(mi)封(feng)座(zuo)：先將密(mi)(mi)封(feng)座(zuo)裝(zhuang)入橡膠油封(feng)，再把密(mi)(mi)封(feng)座(zuo)裝(zhuang)入泵蓋并壓(ya)在軸承(cheng)座(zuo)上，擰緊(jin)螺(luo)母(mu)，確保所有安裝(zhuang)螺(luo)釘(ding)緊(jin)固。當安裝(zhuang)螺(luo)釘(ding)被用(yong)作密(mi)(mi)封(feng)與軸之(zhi)間的(de)驅動(dong)時(shi)，軸應打埋頭(tou)孔(kong)來加固連接，緊(jin)固壓(ya)蓋螺(luo)栓(shuan)時(shi)應該平穩(wen)緊(jin)固，并且不(bu)要(yao)使(shi)壓(ya)蓋受彈(dan)力。在可能(neng)的(de)地方使(shi)用(yong)4個以上螺(luo)釘(ding)的(de)等間距(ju)壓(ya)蓋，緊(jin)固壓(ya)蓋螺(luo)栓(shuan)時(shi)，用(yong)塞尺(chi)檢查軸與壓(ya)蓋之(zhi)間的(de)間隙，這在密(mi)(mi)封(feng)腔對(dui)壓(ya)蓋不(bu)導向(xiang)時(shi)，顯得特別重要(yao)，因(yin)為壓(ya)蓋必須對(dui)中。
