昌寧機械密封利用(yong)機(ji)(ji)械(xie)方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)(he)(he)運(yun)(yun)動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在(zai)機(ji)(ji)械(xie)工程中應(ying)用(yong)非常廣泛，有多種形式，主要包括(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒輪(lun)(lun)齒條(tiao)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)(he)螺旋(xuan)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)(neng)夠(gou)用(yong)于(yu)大功率(lv)(lv)的(de)場合(he)，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)(bi)準確(que)，但一般(ban)要求較高的(de)制造精(jing)度和(he)(he)(he)安(an)裝精(jing)度。還有一類是(shi)靠機(ji)(ji)件間的(de)摩擦(ca)(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)(he)(he)運(yun)(yun)動(dong)(dong)(dong)(dong)的(de)摩擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)(he)(he)摩擦(ca)(ca)輪(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩擦(ca)(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級變速(su)，可以適(shi)應(ying)軸(zhou)間距較大的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合(he)，而(er)過載打滑(hua)還能(neng)(neng)起到緩沖和(he)(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)的(de)作用(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般(ban)不(bu)能(neng)(neng)用(yong)于(yu)大功率(lv)(lv)的(de)場合(he)，也不(bu)能(neng)(neng)保證準確(que)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)(bi)。

　　傳動形式多，但是昌寧機械密封的(de)(de)更換工作大同小異，首(shou)先(xian)拆(chai)前(qian)需確認電機處(chu)于(yu)檢(jian)修狀態，擰下加油螺塞(sai)，用吸管把密封座腔內的(de)(de)潤滑油吸出。準備好放置泵零件的(de)(de)工作臺及拆(chai)裝工具，切勿任意亂(luan)放亂(luan)用，避免碰壞泵的(de)(de)零部件。

　　拆(chai)對分式(shi)聯(lian)軸器(qi)(qi)(qi)：先把(ba)聯(lian)軸器(qi)(qi)(qi)的(de)固定內六(liu)角螺(luo)釘(ding)擰下(xia)(xia)來，再輕輕把(ba)聯(lian)軸器(qi)(qi)(qi)的(de)一(yi)半(ban)從軸上慢慢拉(la)下(xia)(xia)，注意不要掉了，再用梅花扳手擰下(xia)(xia)泵(beng)(beng)軸吊緊螺(luo)栓和擋(dang)塊，讓葉(xie)輪慢慢下(xia)(xia)沉(chen)至(zhi)泵(beng)(beng)體，然后拆(chai)下(xia)(xia)另外一(yi)半(ban)聯(lian)軸器(qi)(qi)(qi)，拿下(xia)(xia)泵(beng)(beng)軸擋(dang)圈。

　　拆卸昌寧機械密封：抓住密(mi)封(feng)彈簧順著泵軸往上提，就能拆(chai)下(xia)來了。

　　拆卸并清(qing)(qing)洗軸(zhou)承(cheng)座：先(xian)輕輕松動一下(xia)軸(zhou)承(cheng)座后用拆卸螺栓頂起(qi)軸(zhou)承(cheng)座，并且沿著泵軸(zhou)往上提(ti)而卸下(xia)，再用噴氣(qi)燃(ran)料清(qing)(qing)洗軸(zhou)承(cheng)及座，裝(zhuang)前(qian)晾干并涂抹少許20號機(ji)械油用來(lai)潤滑保護。

　　拆密封座：擰下密封座壓緊螺母，輕(qing)輕(qing)卸(xie)下密封座并(bing)清洗。

　　昌寧機械密封裝(zhuang)配：在動(dong)、靜(jing)環鏡面上(shang)(shang)涂一層潔凈的20號(hao)潤滑油(you)，導(dao)軸(zhou)承座也抹(mo)(mo)上(shang)(shang)潤滑油(you)，先把靜(jing)環輕輕定位裝(zhuang)入導(dao)軸(zhou)承座，再在泵(beng)軸(zhou)上(shang)(shang)抹(mo)(mo)上(shang)(shang)潤滑油(you)，把動(dong)環部分(fen)輕輕裝(zhuang)入泵(beng)軸(zhou)上(shang)(shang)，用(yong)手輕推密封環應能(neng)伸縮自如，注(zhu)意動(dong)、靜(jing)環部分(fen)的防轉部位需裝(zhuang)配到位。

　　裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)：在電機軸(zhou)(zhou)(zhou)(zhou)頭(tou)上(shang)裝(zhuang)上(shang)擋(dang)圈，裝(zhuang)上(shang)一半(ban)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)，再在泵軸(zhou)(zhou)(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)槽內(nei)裝(zhuang)上(shang)擋(dang)塊并用梅花(hua)扳手擰(ning)緊螺栓；再裝(zhuang)上(shang)另(ling)一半(ban)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)擰(ning)上(shang)內(nei)六角螺釘(ding)。安(an)裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)正確的檢查(cha)要求：對分(fen)式聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)上(shang)下間(jian)隙(xi)需要均勻，用手盤動(dong)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)(qi)幾圈檢查(cha)轉(zhuan)動(dong)的靈活性(xing)。

　　裝密(mi)封座(zuo)：先將密(mi)封座(zuo)裝入橡(xiang)膠油封，再把密(mi)封座(zuo)裝入泵蓋(gai)(gai)并(bing)壓(ya)在(zai)(zai)軸(zhou)(zhou)承座(zuo)上，擰緊螺(luo)母，確保(bao)所有(you)安裝螺(luo)釘緊固。當安裝螺(luo)釘被(bei)用(yong)(yong)作密(mi)封與軸(zhou)(zhou)之間(jian)(jian)的驅動時(shi)，軸(zhou)(zhou)應打埋頭孔來加固連接，緊固壓(ya)蓋(gai)(gai)螺(luo)栓時(shi)應該平穩緊固，并(bing)且不要使壓(ya)蓋(gai)(gai)受彈力。在(zai)(zai)可能的地方(fang)使用(yong)(yong)4個以(yi)上螺(luo)釘的等間(jian)(jian)距壓(ya)蓋(gai)(gai)，緊固壓(ya)蓋(gai)(gai)螺(luo)栓時(shi)，用(yong)(yong)塞尺檢查軸(zhou)(zhou)與壓(ya)蓋(gai)(gai)之間(jian)(jian)的間(jian)(jian)隙，這(zhe)在(zai)(zai)密(mi)封腔對(dui)壓(ya)蓋(gai)(gai)不導向(xiang)時(shi)，顯得特別重要，因為壓(ya)蓋(gai)(gai)必(bi)須對(dui)中。
