　　傳動形式多，但是嘉善機械密封的(de)更(geng)換工(gong)(gong)作大(da)同小(xiao)異，首先拆(chai)前需確認(ren)電機處于(yu)檢修狀態(tai)，擰下加油螺塞，用吸(xi)管把密封座腔內的(de)潤滑油吸(xi)出。準備(bei)好放置泵零(ling)件的(de)工(gong)(gong)作臺及拆(chai)裝工(gong)(gong)具，切(qie)勿任(ren)意亂放亂用，避免碰壞泵的(de)零(ling)部件。

　　拆對分式(shi)聯(lian)(lian)(lian)軸(zhou)(zhou)器：先把聯(lian)(lian)(lian)軸(zhou)(zhou)器的(de)固定內(nei)六角螺(luo)釘擰(ning)下來，再(zai)輕(qing)輕(qing)把聯(lian)(lian)(lian)軸(zhou)(zhou)器的(de)一半(ban)從(cong)軸(zhou)(zhou)上慢慢拉下，注意不要掉了，再(zai)用梅花(hua)扳手(shou)擰(ning)下泵軸(zhou)(zhou)吊緊螺(luo)栓和擋(dang)塊，讓(rang)葉輪慢慢下沉至泵體，然后(hou)拆下另外一半(ban)聯(lian)(lian)(lian)軸(zhou)(zhou)器，拿(na)下泵軸(zhou)(zhou)擋(dang)圈。

　　拆卸嘉善機械密封：抓(zhua)住密封(feng)彈簧順著泵(beng)軸往(wang)上(shang)提，就能(neng)拆下來(lai)了。

　　拆卸并(bing)清洗軸承座：先(xian)輕輕松(song)動一下(xia)軸承座后用拆卸螺栓(shuan)頂起(qi)軸承座，并(bing)且沿著泵(beng)軸往(wang)上提而(er)卸下(xia)，再(zai)用噴氣燃料(liao)清洗軸承及座，裝前晾干并(bing)涂抹少許20號(hao)機械油用來(lai)潤滑保(bao)護。

　　拆(chai)密封(feng)座(zuo)(zuo)：擰(ning)下密封(feng)座(zuo)(zuo)壓緊螺母，輕輕卸下密封(feng)座(zuo)(zuo)并清洗。

　　嘉善機械密封裝(zhuang)配：在動、靜(jing)環(huan)鏡面上涂一層潔凈的20號潤滑油，導軸承座(zuo)也抹上潤滑油，先(xian)把靜(jing)環(huan)輕輕定位裝(zhuang)入導軸承座(zuo)，再在泵軸上抹上潤滑油，把動環(huan)部分輕輕裝(zhuang)入泵軸上，用手(shou)輕推密封環(huan)應能伸縮自如(ru)，注(zhu)意動、靜(jing)環(huan)部分的防轉部位需(xu)裝(zhuang)配到位。

　　裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)：在電機軸(zhou)(zhou)頭上(shang)裝(zhuang)(zhuang)上(shang)擋(dang)圈，裝(zhuang)(zhuang)上(shang)一半(ban)(ban)聯(lian)軸(zhou)(zhou)器(qi)，再(zai)在泵軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)槽內(nei)裝(zhuang)(zhuang)上(shang)擋(dang)塊(kuai)并用梅花(hua)扳手擰緊螺栓；再(zai)裝(zhuang)(zhuang)上(shang)另(ling)一半(ban)(ban)聯(lian)軸(zhou)(zhou)器(qi)擰上(shang)內(nei)六(liu)角(jiao)螺釘。安(an)裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)正(zheng)確的檢(jian)查要(yao)求：對分式(shi)聯(lian)軸(zhou)(zhou)器(qi)上(shang)下間隙需(xu)要(yao)均勻，用手盤動聯(lian)軸(zhou)(zhou)器(qi)幾圈檢(jian)查轉動的靈活性。

　　裝密(mi)(mi)封座(zuo)：先將密(mi)(mi)封座(zuo)裝入橡膠油封，再(zai)把密(mi)(mi)封座(zuo)裝入泵蓋(gai)(gai)并壓(ya)(ya)(ya)在軸承座(zuo)上，擰緊(jin)螺(luo)母，確保所有安裝螺(luo)釘(ding)緊(jin)固。當安裝螺(luo)釘(ding)被用作密(mi)(mi)封與(yu)軸之(zhi)間的驅(qu)動時(shi)(shi)，軸應打埋(mai)頭孔(kong)來加固連接(jie)，緊(jin)固壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時(shi)(shi)應該平(ping)穩緊(jin)固，并且不(bu)要(yao)使(shi)壓(ya)(ya)(ya)蓋(gai)(gai)受彈力。在可能的地(di)方(fang)使(shi)用4個(ge)以上螺(luo)釘(ding)的等間距壓(ya)(ya)(ya)蓋(gai)(gai)，緊(jin)固壓(ya)(ya)(ya)蓋(gai)(gai)螺(luo)栓時(shi)(shi)，用塞尺檢查軸與(yu)壓(ya)(ya)(ya)蓋(gai)(gai)之(zhi)間的間隙，這在密(mi)(mi)封腔對壓(ya)(ya)(ya)蓋(gai)(gai)不(bu)導向時(shi)(shi)，顯得特別重要(yao)，因為壓(ya)(ya)(ya)蓋(gai)(gai)必須對中。
