昌寧機械密封利用機(ji)械(xie)方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在(zai)機(ji)械(xie)工程中(zhong)應用非常廣泛，有多種形式，主要包(bao)(bao)括(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪齒(chi)條(tiao)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用于(yu)大功率(lv)的(de)(de)場(chang)合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)準確，但(dan)一般要求較高的(de)(de)制造(zao)精度和(he)(he)安(an)裝精度。還(huan)有一類(lei)是靠機(ji)件間(jian)的(de)(de)摩(mo)擦(ca)力(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包(bao)(bao)括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)和(he)(he)摩(mo)擦(ca)輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)容易實現無級變(bian)速，可以適應軸間(jian)距較大的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場(chang)合，而過載打(da)滑還(huan)能(neng)起到緩沖(chong)和(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)(de)作(zuo)用，但(dan)這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一般不(bu)能(neng)用于(yu)大功率(lv)的(de)(de)場(chang)合，也不(bu)能(neng)保證準確的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是昌寧機械密封的更換工(gong)作大同小異，首(shou)先拆前需確(que)認電機處于檢修狀態，擰下(xia)加油螺塞(sai)，用吸管把密封座腔內的潤滑油吸出(chu)。準備好放置(zhi)泵(beng)零件的工(gong)作臺及拆裝工(gong)具(ju)，切勿任意亂放亂用，避免(mian)碰壞泵(beng)的零部件。

　　拆對分式聯軸(zhou)(zhou)器：先(xian)把(ba)聯軸(zhou)(zhou)器的固定(ding)內六角螺釘擰下(xia)來，再(zai)輕(qing)輕(qing)把(ba)聯軸(zhou)(zhou)器的一(yi)半(ban)從軸(zhou)(zhou)上慢慢拉下(xia)，注意不要掉(diao)了，再(zai)用梅花扳手(shou)擰下(xia)泵軸(zhou)(zhou)吊緊(jin)螺栓(shuan)和擋(dang)塊，讓葉輪慢慢下(xia)沉至(zhi)泵體，然后拆下(xia)另外一(yi)半(ban)聯軸(zhou)(zhou)器，拿(na)下(xia)泵軸(zhou)(zhou)擋(dang)圈。

　　拆卸昌寧機械密封：抓住(zhu)密封彈簧順著(zhu)泵軸往(wang)上(shang)提，就能(neng)拆(chai)下來了。

　　拆卸并(bing)(bing)清洗軸(zhou)(zhou)承(cheng)座：先輕輕松(song)動一下軸(zhou)(zhou)承(cheng)座后用(yong)(yong)拆卸螺栓頂起軸(zhou)(zhou)承(cheng)座，并(bing)(bing)且沿著(zhu)泵軸(zhou)(zhou)往上提而卸下，再用(yong)(yong)噴氣燃料(liao)清洗軸(zhou)(zhou)承(cheng)及座，裝前(qian)晾干并(bing)(bing)涂抹少許20號機(ji)械油用(yong)(yong)來潤滑保(bao)護。

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

　　昌寧機械密封裝(zhuang)配：在動、靜(jing)環(huan)鏡面上(shang)(shang)涂(tu)一層潔凈(jing)的20號(hao)潤(run)滑油(you)，導軸(zhou)承(cheng)座(zuo)也抹上(shang)(shang)潤(run)滑油(you)，先把靜(jing)環(huan)輕輕定位裝(zhuang)入(ru)導軸(zhou)承(cheng)座(zuo)，再在泵軸(zhou)上(shang)(shang)抹上(shang)(shang)潤(run)滑油(you)，把動環(huan)部(bu)分(fen)輕輕裝(zhuang)入(ru)泵軸(zhou)上(shang)(shang)，用手輕推密封環(huan)應能伸縮自如，注意動、靜(jing)環(huan)部(bu)分(fen)的防(fang)轉部(bu)位需(xu)裝(zhuang)配到位。

　　裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器：在(zai)電機軸(zhou)(zhou)(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈，裝(zhuang)上(shang)一半聯(lian)軸(zhou)(zhou)(zhou)(zhou)器，再在(zai)泵(beng)軸(zhou)(zhou)(zhou)(zhou)端和(he)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器槽內裝(zhuang)上(shang)擋塊并用梅花扳手擰緊螺(luo)栓(shuan)；再裝(zhuang)上(shang)另(ling)一半聯(lian)軸(zhou)(zhou)(zhou)(zhou)器擰上(shang)內六角螺(luo)釘(ding)。安裝(zhuang)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器正確的(de)檢查(cha)要(yao)求：對(dui)分式聯(lian)軸(zhou)(zhou)(zhou)(zhou)器上(shang)下間隙(xi)需要(yao)均(jun)勻，用手盤(pan)動(dong)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器幾圈檢查(cha)轉動(dong)的(de)靈活性。

　　裝密(mi)封(feng)座：先將密(mi)封(feng)座裝入橡膠油(you)封(feng)，再把(ba)密(mi)封(feng)座裝入泵(beng)蓋(gai)(gai)并(bing)壓(ya)(ya)在軸承座上，擰(ning)緊(jin)螺(luo)母，確(que)保所有安裝螺(luo)釘(ding)緊(jin)固(gu)。當安裝螺(luo)釘(ding)被(bei)用作密(mi)封(feng)與(yu)軸之間的(de)(de)驅動時，軸應(ying)(ying)打埋頭孔(kong)來加固(gu)連接，緊(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓時應(ying)(ying)該平(ping)穩緊(jin)固(gu)，并(bing)且不(bu)要使(shi)壓(ya)(ya)蓋(gai)(gai)受彈力。在可(ke)能(neng)的(de)(de)地方使(shi)用4個以上螺(luo)釘(ding)的(de)(de)等間距壓(ya)(ya)蓋(gai)(gai)，緊(jin)固(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓時，用塞尺檢查(cha)軸與(yu)壓(ya)(ya)蓋(gai)(gai)之間的(de)(de)間隙，這在密(mi)封(feng)腔對(dui)壓(ya)(ya)蓋(gai)(gai)不(bu)導向時，顯得特(te)別重(zhong)要，因為壓(ya)(ya)蓋(gai)(gai)必須對(dui)中。
