　　傳動形式多，但是建昌機械密封的(de)更換工(gong)(gong)作(zuo)大同小異，首先拆前(qian)需確認電(dian)機處于檢(jian)修(xiu)狀態(tai)，擰下加油(you)螺塞(sai)，用(yong)吸(xi)管把(ba)密(mi)封座腔內(nei)的(de)潤滑油(you)吸(xi)出。準(zhun)備好放(fang)置泵(beng)(beng)零(ling)件(jian)的(de)工(gong)(gong)作(zuo)臺(tai)及拆裝工(gong)(gong)具，切勿任意(yi)亂(luan)放(fang)亂(luan)用(yong)，避(bi)免碰壞泵(beng)(beng)的(de)零(ling)部件(jian)。

　　拆對分式聯軸(zhou)器(qi)：先把聯軸(zhou)器(qi)的固定內六角螺釘(ding)擰下來，再輕輕把聯軸(zhou)器(qi)的一(yi)半從(cong)軸(zhou)上慢(man)慢(man)拉(la)下，注意不要掉了，再用梅(mei)花扳手擰下泵軸(zhou)吊緊螺栓和擋(dang)塊，讓葉(xie)輪慢(man)慢(man)下沉至泵體，然(ran)后拆下另外一(yi)半聯軸(zhou)器(qi)，拿下泵軸(zhou)擋(dang)圈。

　　拆卸建昌機械密封：抓(zhua)住密封彈簧順著泵軸往上提，就能(neng)拆下來(lai)了(le)。

　　拆(chai)卸(xie)并(bing)(bing)清(qing)洗軸(zhou)承(cheng)座(zuo)(zuo)：先(xian)輕(qing)輕(qing)松(song)動(dong)一(yi)下(xia)軸(zhou)承(cheng)座(zuo)(zuo)后(hou)用(yong)拆(chai)卸(xie)螺栓頂起(qi)軸(zhou)承(cheng)座(zuo)(zuo)，并(bing)(bing)且沿著泵軸(zhou)往(wang)上提而卸(xie)下(xia)，再用(yong)噴氣燃料清(qing)洗軸(zhou)承(cheng)及座(zuo)(zuo)，裝前晾干并(bing)(bing)涂抹(mo)少許20號機械油用(yong)來潤滑保護。

　　拆密封座：擰下密封座壓(ya)緊螺母，輕(qing)輕(qing)卸下密封座并清洗(xi)。

　　建昌機械密封裝(zhuang)配(pei)：在動(dong)、靜(jing)環(huan)鏡面(mian)上(shang)涂一層(ceng)潔凈的20號潤滑油，導軸(zhou)(zhou)承座也抹上(shang)潤滑油，先(xian)把靜(jing)環(huan)輕輕定位(wei)裝(zhuang)入導軸(zhou)(zhou)承座，再在泵軸(zhou)(zhou)上(shang)抹上(shang)潤滑油，把動(dong)環(huan)部分輕輕裝(zhuang)入泵軸(zhou)(zhou)上(shang)，用手輕推密封環(huan)應能(neng)伸縮自如，注意(yi)動(dong)、靜(jing)環(huan)部分的防轉部位(wei)需(xu)裝(zhuang)配(pei)到位(wei)。

　　裝(zhuang)(zhuang)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)：在(zai)電機軸(zhou)(zhou)(zhou)頭上(shang)裝(zhuang)(zhuang)上(shang)擋(dang)(dang)圈(quan)，裝(zhuang)(zhuang)上(shang)一(yi)半聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)，再在(zai)泵(beng)軸(zhou)(zhou)(zhou)端和(he)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)槽內(nei)(nei)裝(zhuang)(zhuang)上(shang)擋(dang)(dang)塊(kuai)并用梅花扳手(shou)擰緊螺栓(shuan)；再裝(zhuang)(zhuang)上(shang)另一(yi)半聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)擰上(shang)內(nei)(nei)六角螺釘。安裝(zhuang)(zhuang)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)正確的(de)檢查要(yao)求：對分(fen)式聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)上(shang)下間隙需要(yao)均勻，用手(shou)盤動(dong)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)(qi)幾圈(quan)檢查轉動(dong)的(de)靈活(huo)性。

　　裝(zhuang)(zhuang)密(mi)封座：先(xian)將密(mi)封座裝(zhuang)(zhuang)入(ru)橡膠(jiao)油封，再把密(mi)封座裝(zhuang)(zhuang)入(ru)泵(beng)蓋(gai)(gai)并壓(ya)在軸(zhou)承座上，擰緊(jin)螺(luo)母，確(que)保所(suo)有安裝(zhuang)(zhuang)螺(luo)釘緊(jin)固。當安裝(zhuang)(zhuang)螺(luo)釘被用作密(mi)封與軸(zhou)之(zhi)(zhi)間的(de)驅(qu)動時，軸(zhou)應打埋(mai)頭(tou)孔來加固連接，緊(jin)固壓(ya)蓋(gai)(gai)螺(luo)栓(shuan)時應該平穩緊(jin)固，并且不(bu)要使(shi)壓(ya)蓋(gai)(gai)受彈力。在可能(neng)的(de)地方使(shi)用4個以上螺(luo)釘的(de)等間距壓(ya)蓋(gai)(gai)，緊(jin)固壓(ya)蓋(gai)(gai)螺(luo)栓(shuan)時，用塞尺檢查軸(zhou)與壓(ya)蓋(gai)(gai)之(zhi)(zhi)間的(de)間隙，這(zhe)在密(mi)封腔對壓(ya)蓋(gai)(gai)不(bu)導向(xiang)時，顯(xian)得特別重要，因為壓(ya)蓋(gai)(gai)必須對中。
