　　傳動形式多，但是射洪機械密封的更換工作大(da)同小異，首先拆前需確(que)認電機處于檢修狀態，擰下加(jia)油螺塞，用(yong)吸管把密封座腔內的潤滑油吸出。準備好放置泵零件(jian)的工作臺及(ji)拆裝(zhuang)工具，切(qie)勿任意亂放亂用(yong)，避(bi)免碰壞泵的零部件(jian)。

　　拆對分式聯(lian)軸(zhou)器：先把聯(lian)軸(zhou)器的(de)固定內六(liu)角螺(luo)釘擰下(xia)來，再輕輕把聯(lian)軸(zhou)器的(de)一半(ban)從軸(zhou)上慢慢拉下(xia)，注意不要掉了(le)，再用梅花扳手(shou)擰下(xia)泵軸(zhou)吊緊螺(luo)栓(shuan)和擋塊，讓(rang)葉輪慢慢下(xia)沉(chen)至(zhi)泵體，然后拆下(xia)另外一半(ban)聯(lian)軸(zhou)器，拿(na)下(xia)泵軸(zhou)擋圈。

　　拆卸射洪機械密封：抓住密(mi)封彈簧順著泵軸往上提，就能拆下(xia)來了。

　　拆(chai)(chai)卸并清洗軸(zhou)承座：先輕輕松(song)動(dong)一下軸(zhou)承座后用拆(chai)(chai)卸螺(luo)栓頂起軸(zhou)承座，并且沿著泵軸(zhou)往上提而(er)卸下，再(zai)用噴氣燃料清洗軸(zhou)承及座，裝前晾(liang)干并涂(tu)抹少許20號機(ji)械油用來潤滑保(bao)護。

　　拆密封(feng)座：擰下(xia)密封(feng)座壓緊螺(luo)母，輕輕卸下(xia)密封(feng)座并清洗。

　　射洪機械密封裝(zhuang)配：在動(dong)、靜(jing)(jing)環(huan)鏡面上(shang)涂一(yi)層(ceng)潔(jie)凈的20號(hao)潤(run)(run)滑油，導(dao)軸承(cheng)座(zuo)也(ye)抹(mo)(mo)上(shang)潤(run)(run)滑油，先把(ba)靜(jing)(jing)環(huan)輕(qing)輕(qing)定(ding)位(wei)裝(zhuang)入(ru)導(dao)軸承(cheng)座(zuo)，再在泵(beng)軸上(shang)抹(mo)(mo)上(shang)潤(run)(run)滑油，把(ba)動(dong)環(huan)部分(fen)輕(qing)輕(qing)裝(zhuang)入(ru)泵(beng)軸上(shang)，用手輕(qing)推密封環(huan)應能伸縮自如，注意動(dong)、靜(jing)(jing)環(huan)部分(fen)的防轉(zhuan)部位(wei)需裝(zhuang)配到(dao)位(wei)。

　　裝(zhuang)聯(lian)軸(zhou)(zhou)器(qi)(qi)：在電機(ji)軸(zhou)(zhou)頭上(shang)(shang)裝(zhuang)上(shang)(shang)擋(dang)圈，裝(zhuang)上(shang)(shang)一半聯(lian)軸(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)(qi)槽內裝(zhuang)上(shang)(shang)擋(dang)塊(kuai)并用梅(mei)花扳手(shou)擰緊螺(luo)栓；再裝(zhuang)上(shang)(shang)另一半聯(lian)軸(zhou)(zhou)器(qi)(qi)擰上(shang)(shang)內六角螺(luo)釘(ding)。安(an)裝(zhuang)聯(lian)軸(zhou)(zhou)器(qi)(qi)正(zheng)確的檢查要求：對分式聯(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)(shang)下間隙需要均勻，用手(shou)盤動(dong)聯(lian)軸(zhou)(zhou)器(qi)(qi)幾圈檢查轉動(dong)的靈活性。

　　裝(zhuang)密(mi)封(feng)(feng)座(zuo)：先將密(mi)封(feng)(feng)座(zuo)裝(zhuang)入橡(xiang)膠油封(feng)(feng)，再把密(mi)封(feng)(feng)座(zuo)裝(zhuang)入泵蓋(gai)并壓(ya)在(zai)軸承座(zuo)上(shang)，擰緊(jin)螺母，確保(bao)所(suo)有安(an)裝(zhuang)螺釘緊(jin)固。當安(an)裝(zhuang)螺釘被用(yong)作密(mi)封(feng)(feng)與軸之間(jian)(jian)的(de)驅動(dong)時(shi)，軸應打埋頭孔來加固連接(jie)，緊(jin)固壓(ya)蓋(gai)螺栓(shuan)時(shi)應該平穩緊(jin)固，并且不要使壓(ya)蓋(gai)受彈力。在(zai)可能的(de)地方使用(yong)4個(ge)以上(shang)螺釘的(de)等間(jian)(jian)距壓(ya)蓋(gai)，緊(jin)固壓(ya)蓋(gai)螺栓(shuan)時(shi)，用(yong)塞尺(chi)檢查軸與壓(ya)蓋(gai)之間(jian)(jian)的(de)間(jian)(jian)隙，這在(zai)密(mi)封(feng)(feng)腔(qiang)對壓(ya)蓋(gai)不導向(xiang)時(shi)，顯得特別(bie)重要，因(yin)為壓(ya)蓋(gai)必須(xu)對中。
