南票機械密封利用(yong)(yong)機(ji)(ji)械(xie)方式傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)(ji)械(xie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)(ji)械(xie)工程(cheng)中(zhong)應(ying)用(yong)(yong)非(fei)常(chang)廣泛，有多種(zhong)形式，主(zhu)要(yao)包括皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)輪(lun)齒(chi)(chi)條(tiao)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能(neng)夠(gou)用(yong)(yong)于(yu)大(da)功率的場合(he)(he)，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準(zhun)確(que)(que)，但一般要(yao)求較(jiao)高(gao)的制造精度和(he)安裝(zhuang)精度。還有一類是靠機(ji)(ji)件間的摩擦(ca)(ca)力傳(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的摩擦(ca)(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)摩擦(ca)(ca)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩擦(ca)(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現無級(ji)變速，可以適應(ying)軸間距較(jiao)大(da)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合(he)(he)，而過載(zai)打滑還能(neng)起到(dao)緩沖和(he)保護(hu)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置(zhi)的作用(yong)(yong)，但這種(zhong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般不(bu)能(neng)用(yong)(yong)于(yu)大(da)功率的場合(he)(he)，也不(bu)能(neng)保證準(zhun)確(que)(que)的傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是南票機械密封的更(geng)換工(gong)(gong)作(zuo)大同小異，首先拆前需確認電(dian)機處(chu)于檢修狀態(tai)，擰下加油螺塞(sai)，用(yong)吸(xi)管把密封(feng)座腔(qiang)內的潤滑油吸(xi)出。準(zhun)備好放置泵零件(jian)的工(gong)(gong)作(zuo)臺及拆裝(zhuang)工(gong)(gong)具(ju)，切勿(wu)任(ren)意(yi)亂放亂用(yong)，避免碰壞泵的零部件(jian)。

　　拆對分式聯(lian)(lian)(lian)軸器：先(xian)把(ba)聯(lian)(lian)(lian)軸器的固定內六角螺釘(ding)擰下(xia)來，再(zai)輕(qing)輕(qing)把(ba)聯(lian)(lian)(lian)軸器的一半從(cong)軸上慢慢拉下(xia)，注(zhu)意不要掉了(le)，再(zai)用梅(mei)花扳手擰下(xia)泵軸吊緊螺栓和擋塊(kuai)，讓葉輪(lun)慢慢下(xia)沉至泵體，然(ran)后拆下(xia)另外一半聯(lian)(lian)(lian)軸器，拿下(xia)泵軸擋圈(quan)。

　　拆卸南票機械密封：抓住密封(feng)彈簧(huang)順著泵軸往上提，就(jiu)能(neng)拆(chai)下來(lai)了。

　　拆卸(xie)并(bing)清(qing)洗(xi)軸(zhou)承(cheng)座(zuo)：先輕(qing)輕(qing)松動一下軸(zhou)承(cheng)座(zuo)后用(yong)拆卸(xie)螺栓(shuan)頂起軸(zhou)承(cheng)座(zuo)，并(bing)且沿著(zhu)泵(beng)軸(zhou)往上提而卸(xie)下，再(zai)用(yong)噴氣燃料(liao)清(qing)洗(xi)軸(zhou)承(cheng)及座(zuo)，裝前晾干并(bing)涂抹(mo)少許20號機械油用(yong)來(lai)潤滑保(bao)護。

　　拆密(mi)封座：擰下(xia)密(mi)封座壓緊(jin)螺(luo)母，輕(qing)輕(qing)卸下(xia)密(mi)封座并清洗。

　　南票機械密封裝(zhuang)配(pei)：在動、靜環鏡面上(shang)涂一層潔(jie)凈(jing)的20號潤(run)滑油(you)，導軸承座也抹(mo)上(shang)潤(run)滑油(you)，先把靜環輕輕定位裝(zhuang)入(ru)導軸承座，再在泵軸上(shang)抹(mo)上(shang)潤(run)滑油(you)，把動環部分輕輕裝(zhuang)入(ru)泵軸上(shang)，用(yong)手(shou)輕推密封環應能伸(shen)縮自(zi)如，注意(yi)動、靜環部分的防轉部位需裝(zhuang)配(pei)到(dao)位。

　　裝(zhuang)聯(lian)軸(zhou)(zhou)器(qi)：在(zai)電機軸(zhou)(zhou)頭上(shang)裝(zhuang)上(shang)擋圈，裝(zhuang)上(shang)一半聯(lian)軸(zhou)(zhou)器(qi)，再(zai)在(zai)泵軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)槽內裝(zhuang)上(shang)擋塊并用梅(mei)花扳手擰緊螺栓；再(zai)裝(zhuang)上(shang)另(ling)一半聯(lian)軸(zhou)(zhou)器(qi)擰上(shang)內六角螺釘。安裝(zhuang)聯(lian)軸(zhou)(zhou)器(qi)正確的檢(jian)(jian)查要求：對分式聯(lian)軸(zhou)(zhou)器(qi)上(shang)下間隙需要均勻，用手盤動聯(lian)軸(zhou)(zhou)器(qi)幾圈檢(jian)(jian)查轉動的靈活性。

　　裝(zhuang)密(mi)封座(zuo)(zuo)：先(xian)將密(mi)封座(zuo)(zuo)裝(zhuang)入橡膠(jiao)油封，再把密(mi)封座(zuo)(zuo)裝(zhuang)入泵蓋(gai)(gai)并壓(ya)(ya)在軸(zhou)承座(zuo)(zuo)上(shang)，擰緊螺(luo)母，確保所有安(an)裝(zhuang)螺(luo)釘緊固(gu)(gu)(gu)。當安(an)裝(zhuang)螺(luo)釘被用(yong)作密(mi)封與(yu)軸(zhou)之間(jian)(jian)的(de)驅(qu)動(dong)時(shi)，軸(zhou)應(ying)打埋頭孔(kong)來加固(gu)(gu)(gu)連接，緊固(gu)(gu)(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓時(shi)應(ying)該平穩緊固(gu)(gu)(gu)，并且不要使壓(ya)(ya)蓋(gai)(gai)受彈力(li)。在可能的(de)地(di)方使用(yong)4個以上(shang)螺(luo)釘的(de)等間(jian)(jian)距壓(ya)(ya)蓋(gai)(gai)，緊固(gu)(gu)(gu)壓(ya)(ya)蓋(gai)(gai)螺(luo)栓時(shi)，用(yong)塞尺檢(jian)查軸(zhou)與(yu)壓(ya)(ya)蓋(gai)(gai)之間(jian)(jian)的(de)間(jian)(jian)隙，這(zhe)在密(mi)封腔(qiang)對(dui)壓(ya)(ya)蓋(gai)(gai)不導向時(shi)，顯得特別重(zhong)要，因為(wei)壓(ya)(ya)蓋(gai)(gai)必須對(dui)中。
