　　傳動形式多，但是平湖機械密封的(de)(de)更(geng)換工作(zuo)大同小異，首先拆前需確認電機處于檢修狀態，擰下加(jia)油螺塞(sai)，用吸管把密(mi)封座腔內(nei)的(de)(de)潤滑油吸出。準(zhun)備(bei)好放(fang)置泵零件的(de)(de)工作(zuo)臺及拆裝(zhuang)工具(ju)，切勿任(ren)意(yi)亂(luan)(luan)放(fang)亂(luan)(luan)用，避免碰壞泵的(de)(de)零部件。

　　拆對分式(shi)聯(lian)軸器：先把聯(lian)軸器的(de)固定內六角(jiao)螺釘擰下(xia)(xia)(xia)來，再輕輕把聯(lian)軸器的(de)一半(ban)(ban)從軸上(shang)慢(man)慢(man)拉下(xia)(xia)(xia)，注意(yi)不要掉了，再用梅花(hua)扳手(shou)擰下(xia)(xia)(xia)泵(beng)軸吊(diao)緊(jin)螺栓和(he)擋(dang)塊(kuai)，讓(rang)葉輪慢(man)慢(man)下(xia)(xia)(xia)沉至(zhi)泵(beng)體，然后拆下(xia)(xia)(xia)另外一半(ban)(ban)聯(lian)軸器，拿下(xia)(xia)(xia)泵(beng)軸擋(dang)圈。

　　拆卸平湖機械密封：抓住密封彈(dan)簧順著泵軸往上提，就能拆下來了。

　　拆(chai)(chai)卸(xie)并(bing)清洗(xi)軸(zhou)承座：先輕(qing)輕(qing)松(song)動(dong)一下軸(zhou)承座后用拆(chai)(chai)卸(xie)螺栓頂起(qi)軸(zhou)承座，并(bing)且沿著泵軸(zhou)往上提而卸(xie)下，再用噴氣燃料清洗(xi)軸(zhou)承及座，裝前晾干并(bing)涂抹少許(xu)20號機械(xie)油用來潤滑保護。

　　拆密封(feng)座(zuo)：擰下(xia)密封(feng)座(zuo)壓緊螺母，輕輕卸(xie)下(xia)密封(feng)座(zuo)并清洗。

　　平湖機械密封裝(zhuang)(zhuang)(zhuang)配：在動、靜環(huan)(huan)鏡面上(shang)涂一層潔凈的20號(hao)潤滑(hua)油(you)，導(dao)軸(zhou)承(cheng)座也(ye)抹(mo)上(shang)潤滑(hua)油(you)，先把(ba)靜環(huan)(huan)輕(qing)輕(qing)定位(wei)裝(zhuang)(zhuang)(zhuang)入導(dao)軸(zhou)承(cheng)座，再在泵(beng)軸(zhou)上(shang)抹(mo)上(shang)潤滑(hua)油(you)，把(ba)動環(huan)(huan)部(bu)分輕(qing)輕(qing)裝(zhuang)(zhuang)(zhuang)入泵(beng)軸(zhou)上(shang)，用手(shou)輕(qing)推密(mi)封(feng)環(huan)(huan)應能伸縮自如(ru)，注意(yi)動、靜環(huan)(huan)部(bu)分的防(fang)轉部(bu)位(wei)需裝(zhuang)(zhuang)(zhuang)配到位(wei)。

　　裝聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)：在電機軸(zhou)(zhou)頭上(shang)裝上(shang)擋圈，裝上(shang)一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)，再在泵(beng)軸(zhou)(zhou)端和(he)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)槽內裝上(shang)擋塊并用梅(mei)花扳手擰緊螺栓；再裝上(shang)另一(yi)半聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)擰上(shang)內六角螺釘。安裝聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)正確的檢查要求(qiu)：對分式(shi)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)下間隙需要均(jun)勻(yun)，用手盤動聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)幾(ji)圈檢查轉動的靈活性(xing)。

　　裝密(mi)封(feng)(feng)座(zuo)：先將密(mi)封(feng)(feng)座(zuo)裝入橡膠油封(feng)(feng)，再(zai)把密(mi)封(feng)(feng)座(zuo)裝入泵蓋(gai)并壓(ya)在(zai)軸(zhou)承座(zuo)上，擰緊螺(luo)(luo)母(mu)，確保所有安裝螺(luo)(luo)釘緊固(gu)(gu)。當安裝螺(luo)(luo)釘被用(yong)(yong)作密(mi)封(feng)(feng)與軸(zhou)之(zhi)間的驅動時(shi)，軸(zhou)應打埋頭孔來加固(gu)(gu)連接，緊固(gu)(gu)壓(ya)蓋(gai)螺(luo)(luo)栓時(shi)應該平穩緊固(gu)(gu)，并且不要使壓(ya)蓋(gai)受彈(dan)力。在(zai)可能(neng)的地方使用(yong)(yong)4個(ge)以上螺(luo)(luo)釘的等間距壓(ya)蓋(gai)，緊固(gu)(gu)壓(ya)蓋(gai)螺(luo)(luo)栓時(shi)，用(yong)(yong)塞(sai)尺檢查軸(zhou)與壓(ya)蓋(gai)之(zhi)間的間隙，這在(zai)密(mi)封(feng)(feng)腔對(dui)壓(ya)蓋(gai)不導向時(shi)，顯得特別重要，因為(wei)壓(ya)蓋(gai)必(bi)須(xu)對(dui)中。
