　　傳動形式多，但是木魚鎮機械密封的更(geng)換工作大同小異(yi)，首先拆前需確認電機處于檢修(xiu)狀態(tai)，擰下加油(you)螺塞，用吸(xi)管把密封(feng)座腔(qiang)內(nei)的潤滑油(you)吸(xi)出。準備好放置(zhi)泵(beng)零(ling)(ling)件(jian)(jian)的工作臺及拆裝工具，切勿任(ren)意亂(luan)放亂(luan)用，避免(mian)碰壞泵(beng)的零(ling)(ling)部件(jian)(jian)。

　　拆對分式聯軸(zhou)(zhou)(zhou)(zhou)器(qi)：先把聯軸(zhou)(zhou)(zhou)(zhou)器(qi)的(de)固定內六角螺釘擰下來，再(zai)輕輕把聯軸(zhou)(zhou)(zhou)(zhou)器(qi)的(de)一(yi)半(ban)從軸(zhou)(zhou)(zhou)(zhou)上慢慢拉(la)下，注意不要掉了，再(zai)用梅花扳手擰下泵軸(zhou)(zhou)(zhou)(zhou)吊(diao)緊(jin)螺栓和擋塊，讓葉輪慢慢下沉(chen)至泵體(ti)，然(ran)后拆下另(ling)外一(yi)半(ban)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)，拿下泵軸(zhou)(zhou)(zhou)(zhou)擋圈。

　　拆卸木魚鎮機械密封：抓住密封彈簧(huang)順著泵軸往上提，就能拆下(xia)來(lai)了。

　　拆卸(xie)并清(qing)洗軸(zhou)(zhou)承(cheng)座：先輕輕松動一下(xia)軸(zhou)(zhou)承(cheng)座后用(yong)拆卸(xie)螺栓頂起軸(zhou)(zhou)承(cheng)座，并且沿著泵軸(zhou)(zhou)往(wang)上提而卸(xie)下(xia)，再用(yong)噴氣(qi)燃料清(qing)洗軸(zhou)(zhou)承(cheng)及座，裝前晾干并涂抹少許20號(hao)機械油(you)用(yong)來潤(run)滑保護(hu)。

　　拆密(mi)(mi)封座(zuo)(zuo)：擰下密(mi)(mi)封座(zuo)(zuo)壓緊(jin)螺母，輕輕卸下密(mi)(mi)封座(zuo)(zuo)并清洗(xi)。

　　木魚鎮機械密封裝配：在(zai)動(dong)、靜(jing)(jing)環(huan)鏡面上(shang)(shang)涂(tu)一層潔凈(jing)的(de)20號潤(run)滑油，導軸(zhou)承座也抹上(shang)(shang)潤(run)滑油，先把(ba)靜(jing)(jing)環(huan)輕(qing)輕(qing)定位(wei)裝入(ru)導軸(zhou)承座，再在(zai)泵軸(zhou)上(shang)(shang)抹上(shang)(shang)潤(run)滑油，把(ba)動(dong)環(huan)部(bu)分輕(qing)輕(qing)裝入(ru)泵軸(zhou)上(shang)(shang)，用手輕(qing)推(tui)密封環(huan)應能伸(shen)縮自如(ru)，注意動(dong)、靜(jing)(jing)環(huan)部(bu)分的(de)防轉部(bu)位(wei)需裝配到(dao)位(wei)。

　　裝聯(lian)(lian)軸(zhou)(zhou)器(qi)：在(zai)電機軸(zhou)(zhou)頭上(shang)裝上(shang)擋(dang)圈(quan)，裝上(shang)一半聯(lian)(lian)軸(zhou)(zhou)器(qi)，再在(zai)泵軸(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)器(qi)槽內裝上(shang)擋(dang)塊并用(yong)梅花扳手擰緊螺栓；再裝上(shang)另(ling)一半聯(lian)(lian)軸(zhou)(zhou)器(qi)擰上(shang)內六(liu)角螺釘。安(an)裝聯(lian)(lian)軸(zhou)(zhou)器(qi)正確的(de)檢查要求：對分式(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)上(shang)下間隙需(xu)要均(jun)勻，用(yong)手盤動聯(lian)(lian)軸(zhou)(zhou)器(qi)幾圈(quan)檢查轉動的(de)靈活性。

　　裝(zhuang)(zhuang)密(mi)封(feng)座：先將密(mi)封(feng)座裝(zhuang)(zhuang)入橡膠油封(feng)，再把密(mi)封(feng)座裝(zhuang)(zhuang)入泵(beng)蓋(gai)(gai)(gai)并(bing)壓(ya)(ya)在(zai)軸承座上，擰緊(jin)螺母，確保所有安(an)裝(zhuang)(zhuang)螺釘緊(jin)固(gu)(gu)。當安(an)裝(zhuang)(zhuang)螺釘被用(yong)作密(mi)封(feng)與軸之間的(de)驅(qu)動時(shi)，軸應(ying)打埋頭(tou)孔來加(jia)固(gu)(gu)連(lian)接，緊(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺栓(shuan)時(shi)應(ying)該平穩緊(jin)固(gu)(gu)，并(bing)且不要(yao)使壓(ya)(ya)蓋(gai)(gai)(gai)受(shou)彈力(li)。在(zai)可(ke)能的(de)地方使用(yong)4個以上螺釘的(de)等(deng)間距壓(ya)(ya)蓋(gai)(gai)(gai)，緊(jin)固(gu)(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺栓(shuan)時(shi)，用(yong)塞尺檢查軸與壓(ya)(ya)蓋(gai)(gai)(gai)之間的(de)間隙，這在(zai)密(mi)封(feng)腔對(dui)(dui)壓(ya)(ya)蓋(gai)(gai)(gai)不導(dao)向時(shi)，顯得特別重要(yao)，因為(wei)壓(ya)(ya)蓋(gai)(gai)(gai)必須對(dui)(dui)中。
