　　傳動形式多，但是長清機械密封的(de)更換(huan)工(gong)作(zuo)大同小異，首先拆(chai)前需確認(ren)電機處于檢修(xiu)狀態，擰下加油螺塞(sai)，用吸(xi)管(guan)把密封座腔內的(de)潤(run)滑油吸(xi)出。準備好(hao)放置泵(beng)零(ling)件的(de)工(gong)作(zuo)臺及拆(chai)裝工(gong)具(ju)，切勿任(ren)意亂(luan)(luan)放亂(luan)(luan)用，避免(mian)碰壞泵(beng)的(de)零(ling)部(bu)件。

　　拆對分式聯軸(zhou)(zhou)器：先把(ba)聯軸(zhou)(zhou)器的固定內(nei)六角螺釘(ding)擰(ning)下(xia)來(lai)，再輕輕把(ba)聯軸(zhou)(zhou)器的一(yi)半從軸(zhou)(zhou)上慢(man)(man)慢(man)(man)拉下(xia)，注意(yi)不要(yao)掉了，再用梅花扳手擰(ning)下(xia)泵軸(zhou)(zhou)吊(diao)緊螺栓和擋(dang)塊，讓(rang)葉輪慢(man)(man)慢(man)(man)下(xia)沉至泵體(ti)，然(ran)后拆下(xia)另外一(yi)半聯軸(zhou)(zhou)器，拿下(xia)泵軸(zhou)(zhou)擋(dang)圈。

　　拆卸長清機械密封：抓(zhua)住密封(feng)彈簧順著泵軸往上提(ti)，就能拆下來了。

　　拆卸并清(qing)洗(xi)軸(zhou)承(cheng)座(zuo)：先輕輕松(song)動一下軸(zhou)承(cheng)座(zuo)后用(yong)拆卸螺栓頂起軸(zhou)承(cheng)座(zuo)，并且沿著泵軸(zhou)往上提(ti)而卸下，再用(yong)噴氣燃料(liao)清(qing)洗(xi)軸(zhou)承(cheng)及座(zuo)，裝前晾(liang)干并涂(tu)抹少(shao)許20號機械油用(yong)來潤滑保護。

　　拆(chai)密封(feng)座(zuo)(zuo)：擰下密封(feng)座(zuo)(zuo)壓緊(jin)螺母(mu)，輕(qing)輕(qing)卸下密封(feng)座(zuo)(zuo)并清洗。

　　長清機械密封裝配(pei)：在動、靜環鏡面上(shang)(shang)涂(tu)一層潔(jie)凈(jing)的20號潤(run)(run)滑油，導軸(zhou)(zhou)承(cheng)座也抹上(shang)(shang)潤(run)(run)滑油，先把(ba)靜環輕(qing)輕(qing)定位(wei)裝入導軸(zhou)(zhou)承(cheng)座，再在泵(beng)(beng)軸(zhou)(zhou)上(shang)(shang)抹上(shang)(shang)潤(run)(run)滑油，把(ba)動環部分(fen)輕(qing)輕(qing)裝入泵(beng)(beng)軸(zhou)(zhou)上(shang)(shang)，用(yong)手(shou)輕(qing)推密封(feng)環應能伸縮(suo)自(zi)如(ru)，注意動、靜環部分(fen)的防轉部位(wei)需裝配(pei)到位(wei)。

　　裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)：在(zai)電(dian)機軸(zhou)(zhou)(zhou)頭上(shang)裝(zhuang)(zhuang)上(shang)擋(dang)圈，裝(zhuang)(zhuang)上(shang)一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)，再在(zai)泵軸(zhou)(zhou)(zhou)端和聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)槽(cao)內裝(zhuang)(zhuang)上(shang)擋(dang)塊并用(yong)梅花扳(ban)手擰緊螺(luo)栓；再裝(zhuang)(zhuang)上(shang)另一半聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)擰上(shang)內六(liu)角螺(luo)釘。安裝(zhuang)(zhuang)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)正確的檢(jian)查要求(qiu)：對分式聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)上(shang)下間隙需要均勻，用(yong)手盤動聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)(qi)幾圈檢(jian)查轉動的靈活性(xing)。

　　裝(zhuang)密封(feng)座(zuo)：先將密封(feng)座(zuo)裝(zhuang)入橡(xiang)膠油(you)封(feng)，再把密封(feng)座(zuo)裝(zhuang)入泵蓋(gai)(gai)并壓(ya)(ya)在軸(zhou)承座(zuo)上，擰緊螺(luo)母(mu)，確保所有安裝(zhuang)螺(luo)釘緊固(gu)。當安裝(zhuang)螺(luo)釘被用作密封(feng)與軸(zhou)之間(jian)(jian)的(de)(de)驅動(dong)時(shi)，軸(zhou)應打埋(mai)頭孔來(lai)加(jia)固(gu)連(lian)接(jie)，緊固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)應該平(ping)穩緊固(gu)，并且不要使(shi)壓(ya)(ya)蓋(gai)(gai)受彈(dan)力。在可能的(de)(de)地方(fang)使(shi)用4個以上螺(luo)釘的(de)(de)等間(jian)(jian)距壓(ya)(ya)蓋(gai)(gai)，緊固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓(shuan)時(shi)，用塞尺(chi)檢查軸(zhou)與壓(ya)(ya)蓋(gai)(gai)之間(jian)(jian)的(de)(de)間(jian)(jian)隙，這(zhe)在密封(feng)腔(qiang)對壓(ya)(ya)蓋(gai)(gai)不導向時(shi)，顯得特別重要，因(yin)為壓(ya)(ya)蓋(gai)(gai)必須對中。
