　　傳動形式多，但是樂至機械密封的(de)更(geng)換工(gong)作(zuo)大(da)同小異，首先(xian)拆前(qian)需(xu)確認(ren)電機處于(yu)檢修狀態，擰下(xia)加油螺(luo)塞，用吸管把(ba)密(mi)封(feng)座(zuo)腔內(nei)的(de)潤滑(hua)油吸出。準備(bei)好放置泵(beng)(beng)零件的(de)工(gong)作(zuo)臺及拆裝工(gong)具，切勿(wu)任意(yi)亂放亂用，避免碰壞泵(beng)(beng)的(de)零部件。

　　拆對(dui)分式聯軸(zhou)器(qi)：先把聯軸(zhou)器(qi)的固定內六(liu)角螺(luo)釘(ding)擰下(xia)來，再輕(qing)(qing)輕(qing)(qing)把聯軸(zhou)器(qi)的一(yi)半從軸(zhou)上(shang)慢(man)(man)慢(man)(man)拉下(xia)，注意不要掉(diao)了，再用(yong)梅花扳(ban)手擰下(xia)泵(beng)軸(zhou)吊緊(jin)螺(luo)栓(shuan)和擋(dang)塊(kuai)，讓葉輪慢(man)(man)慢(man)(man)下(xia)沉至泵(beng)體，然(ran)后拆下(xia)另外一(yi)半聯軸(zhou)器(qi)，拿下(xia)泵(beng)軸(zhou)擋(dang)圈。

　　拆卸樂至機械密封：抓(zhua)住密封彈簧順(shun)著泵軸往上提，就能(neng)拆下來了。

　　拆卸(xie)并(bing)清洗軸(zhou)承座(zuo)：先輕輕松動一(yi)下軸(zhou)承座(zuo)后用拆卸(xie)螺(luo)栓頂起軸(zhou)承座(zuo)，并(bing)且沿著泵軸(zhou)往上提而卸(xie)下，再(zai)用噴氣燃料清洗軸(zhou)承及(ji)座(zuo)，裝(zhuang)前晾(liang)干并(bing)涂抹(mo)少許20號(hao)機械油(you)用來潤(run)滑(hua)保護(hu)。

　　拆密(mi)(mi)封座：擰下密(mi)(mi)封座壓緊螺母，輕(qing)輕(qing)卸下密(mi)(mi)封座并清洗。

　　樂至機械密封裝(zhuang)(zhuang)配(pei)：在動(dong)、靜(jing)環鏡面上涂一層潔凈的20號潤(run)滑油，導軸(zhou)承座也抹(mo)上潤(run)滑油，先把(ba)靜(jing)環輕輕定(ding)位(wei)裝(zhuang)(zhuang)入(ru)導軸(zhou)承座，再(zai)在泵軸(zhou)上抹(mo)上潤(run)滑油，把(ba)動(dong)環部分輕輕裝(zhuang)(zhuang)入(ru)泵軸(zhou)上，用手輕推密封環應能伸縮自如，注(zhu)意動(dong)、靜(jing)環部分的防轉部位(wei)需裝(zhuang)(zhuang)配(pei)到位(wei)。

　　裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)(qi)：在電機軸(zhou)(zhou)頭上(shang)裝(zhuang)(zhuang)上(shang)擋圈，裝(zhuang)(zhuang)上(shang)一(yi)半聯(lian)軸(zhou)(zhou)器(qi)(qi)，再(zai)(zai)在泵軸(zhou)(zhou)端和(he)聯(lian)軸(zhou)(zhou)器(qi)(qi)槽內(nei)裝(zhuang)(zhuang)上(shang)擋塊并用梅花扳(ban)手(shou)擰(ning)(ning)緊螺栓；再(zai)(zai)裝(zhuang)(zhuang)上(shang)另(ling)一(yi)半聯(lian)軸(zhou)(zhou)器(qi)(qi)擰(ning)(ning)上(shang)內(nei)六角螺釘。安裝(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)(qi)正(zheng)確的檢查要求：對分式(shi)聯(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)下間隙需要均勻，用手(shou)盤動聯(lian)軸(zhou)(zhou)器(qi)(qi)幾圈檢查轉動的靈活性。

　　裝密封(feng)座(zuo)：先將密封(feng)座(zuo)裝入橡(xiang)膠油封(feng)，再把密封(feng)座(zuo)裝入泵蓋(gai)(gai)(gai)并壓(ya)(ya)在軸(zhou)承(cheng)座(zuo)上(shang)，擰緊(jin)螺(luo)(luo)母(mu)，確(que)保(bao)所有安裝螺(luo)(luo)釘緊(jin)固(gu)。當安裝螺(luo)(luo)釘被用作密封(feng)與軸(zhou)之(zhi)間的(de)驅動時(shi)，軸(zhou)應打埋頭孔來加固(gu)連接，緊(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi)應該平穩緊(jin)固(gu)，并且不(bu)要使壓(ya)(ya)蓋(gai)(gai)(gai)受彈(dan)力。在可能(neng)的(de)地(di)方使用4個以上(shang)螺(luo)(luo)釘的(de)等間距壓(ya)(ya)蓋(gai)(gai)(gai)，緊(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)(luo)栓時(shi)，用塞尺檢(jian)查軸(zhou)與壓(ya)(ya)蓋(gai)(gai)(gai)之(zhi)間的(de)間隙，這在密封(feng)腔(qiang)對壓(ya)(ya)蓋(gai)(gai)(gai)不(bu)導向時(shi)，顯得特別重要，因為壓(ya)(ya)蓋(gai)(gai)(gai)必(bi)須(xu)對中。
