什玲鎮機械密封利用機械方式(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)(di)動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)在(zai)機械工程中應(ying)用非常(chang)廣泛，有多種(zhong)(zhong)形式(shi)，主要(yao)包括皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、蝸桿(gan)蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(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(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)夠用于大功(gong)(gong)率的(de)場合(he)(he)，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比準確(que)(que)，但(dan)一(yi)般(ban)要(yao)求較(jiao)高的(de)制造精度和(he)(he)安裝精度。還(huan)有一(yi)類是靠機件間的(de)摩(mo)擦(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)(di)動(dong)(dong)(dong)(dong)(dong)(dong)力和(he)(he)運動(dong)(dong)(dong)(dong)(dong)(dong)的(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，包括帶傳(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(lun)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)容易實現無級變速，可以適應(ying)軸間距較(jiao)大的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)場合(he)(he)，而過載打滑還(huan)能(neng)起到緩沖和(he)(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)作用，但(dan)這種(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)一(yi)般(ban)不(bu)能(neng)用于大功(gong)(gong)率的(de)場合(he)(he)，也(ye)不(bu)能(neng)保證準確(que)(que)的(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是什玲鎮機械密封的更(geng)換工(gong)作(zuo)大同小異，首先拆前需確認電(dian)機(ji)處于檢修狀態，擰下加油(you)螺塞，用吸(xi)管(guan)把密封座(zuo)腔內的潤滑(hua)油(you)吸(xi)出。準備好(hao)放置泵零件的工(gong)作(zuo)臺及拆裝工(gong)具(ju)，切勿(wu)任意亂(luan)放亂(luan)用，避免(mian)碰壞(huai)泵的零部件。

　　拆(chai)對分式聯(lian)軸(zhou)(zhou)器：先把(ba)聯(lian)軸(zhou)(zhou)器的固定內六角螺(luo)釘擰(ning)下來，再輕(qing)輕(qing)把(ba)聯(lian)軸(zhou)(zhou)器的一(yi)半(ban)從軸(zhou)(zhou)上慢(man)慢(man)拉下，注意不要(yao)掉了，再用梅花(hua)扳(ban)手擰(ning)下泵軸(zhou)(zhou)吊緊螺(luo)栓和擋(dang)塊，讓葉輪慢(man)慢(man)下沉(chen)至泵體，然后拆(chai)下另外一(yi)半(ban)聯(lian)軸(zhou)(zhou)器，拿下泵軸(zhou)(zhou)擋(dang)圈。

　　拆卸什玲鎮機械密封：抓(zhua)住密封彈簧(huang)順(shun)著泵軸往上提，就能(neng)拆下來了。

　　拆(chai)卸(xie)并(bing)清(qing)洗軸承(cheng)座：先輕(qing)輕(qing)松動一下(xia)軸承(cheng)座后用拆(chai)卸(xie)螺栓頂起(qi)軸承(cheng)座，并(bing)且沿著泵軸往上提而卸(xie)下(xia)，再用噴氣燃料(liao)清(qing)洗軸承(cheng)及座，裝前晾干并(bing)涂抹少許20號(hao)機械油用來(lai)潤滑保護。

　　拆密(mi)封座(zuo)(zuo)：擰下(xia)密(mi)封座(zuo)(zuo)壓緊螺(luo)母，輕輕卸下(xia)密(mi)封座(zuo)(zuo)并(bing)清(qing)洗。

　　什玲鎮機械密封裝(zhuang)配：在動、靜(jing)環(huan)鏡面(mian)上涂一層潔(jie)凈的(de)20號潤(run)滑油(you)，導(dao)軸(zhou)承(cheng)座也抹上潤(run)滑油(you)，先把靜(jing)環(huan)輕輕定位裝(zhuang)入導(dao)軸(zhou)承(cheng)座，再在泵(beng)軸(zhou)上抹上潤(run)滑油(you)，把動環(huan)部(bu)(bu)分輕輕裝(zhuang)入泵(beng)軸(zhou)上，用手輕推密封環(huan)應(ying)能伸縮自如，注意動、靜(jing)環(huan)部(bu)(bu)分的(de)防轉(zhuan)部(bu)(bu)位需(xu)裝(zhuang)配到位。

　　裝聯(lian)軸(zhou)器：在電機軸(zhou)頭上(shang)(shang)裝上(shang)(shang)擋圈，裝上(shang)(shang)一(yi)半(ban)聯(lian)軸(zhou)器，再(zai)在泵軸(zhou)端和聯(lian)軸(zhou)器槽(cao)內裝上(shang)(shang)擋塊并用梅花(hua)扳手擰緊螺栓；再(zai)裝上(shang)(shang)另一(yi)半(ban)聯(lian)軸(zhou)器擰上(shang)(shang)內六角螺釘(ding)。安裝聯(lian)軸(zhou)器正(zheng)確的檢(jian)查要(yao)求：對(dui)分式聯(lian)軸(zhou)器上(shang)(shang)下間隙需要(yao)均勻，用手盤動聯(lian)軸(zhou)器幾圈檢(jian)查轉動的靈活(huo)性。

　　裝(zhuang)密(mi)封(feng)(feng)(feng)座：先(xian)將密(mi)封(feng)(feng)(feng)座裝(zhuang)入橡膠(jiao)油封(feng)(feng)(feng)，再把密(mi)封(feng)(feng)(feng)座裝(zhuang)入泵蓋(gai)(gai)并(bing)壓在軸承座上(shang)，擰緊螺(luo)母，確保所有安裝(zhuang)螺(luo)釘(ding)緊固(gu)。當安裝(zhuang)螺(luo)釘(ding)被用(yong)作密(mi)封(feng)(feng)(feng)與(yu)(yu)軸之間(jian)(jian)的(de)驅動(dong)時，軸應打埋頭孔來加固(gu)連接(jie)，緊固(gu)壓蓋(gai)(gai)螺(luo)栓(shuan)時應該平(ping)穩緊固(gu)，并(bing)且(qie)不要使壓蓋(gai)(gai)受彈力(li)。在可(ke)能的(de)地方(fang)使用(yong)4個以(yi)上(shang)螺(luo)釘(ding)的(de)等間(jian)(jian)距壓蓋(gai)(gai)，緊固(gu)壓蓋(gai)(gai)螺(luo)栓(shuan)時，用(yong)塞尺檢查軸與(yu)(yu)壓蓋(gai)(gai)之間(jian)(jian)的(de)間(jian)(jian)隙，這在密(mi)封(feng)(feng)(feng)腔(qiang)對壓蓋(gai)(gai)不導(dao)向時，顯(xian)得特別(bie)重要，因為壓蓋(gai)(gai)必須對中。
