西昌鎮機械密封利用(yong)機(ji)械(xie)方式傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力和運(yun)動(dong)(dong)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)在機(ji)械(xie)工程中應(ying)用(yong)非常廣泛，有多(duo)種形式，主要(yao)包(bao)括皮帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、蝸(gua)(gua)桿蝸(gua)(gua)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、齒(chi)(chi)(chi)輪(lun)齒(chi)(chi)(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等。齒(chi)(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)能夠用(yong)于大功(gong)率(lv)的(de)(de)場合(he)，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比(bi)準確(que)，但一般要(yao)求較高的(de)(de)制造精度和安(an)裝(zhuang)精度。還有一類(lei)是靠(kao)機(ji)件間的(de)(de)摩(mo)擦(ca)力傳(chuan)(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力和運(yun)動(dong)(dong)的(de)(de)摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)，包(bao)括帶(dai)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)和摩(mo)擦(ca)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等。摩(mo)擦(ca)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)容易實(shi)現(xian)無級變速，可以適應(ying)軸間距較大的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)場合(he)，而過載打滑還能起到緩沖和保(bao)(bao)護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)裝(zhuang)置的(de)(de)作用(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)一般不(bu)能用(yong)于大功(gong)率(lv)的(de)(de)場合(he)，也不(bu)能保(bao)(bao)證準確(que)的(de)(de)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)比(bi)。

　　傳動形式多，但是西昌鎮機械密封的(de)更換(huan)工(gong)作大(da)同小異，首先拆(chai)前需確認電機處(chu)于檢修狀態，擰下加油螺塞，用(yong)吸管把(ba)密(mi)封(feng)座腔內的(de)潤滑油吸出(chu)。準備好放(fang)(fang)置(zhi)泵零(ling)件的(de)工(gong)作臺及拆(chai)裝工(gong)具(ju)，切勿任意亂(luan)放(fang)(fang)亂(luan)用(yong)，避(bi)免碰(peng)壞泵的(de)零(ling)部件。

　　拆對分(fen)式聯(lian)軸(zhou)(zhou)器：先把(ba)聯(lian)軸(zhou)(zhou)器的固定內六角螺釘擰(ning)下來，再(zai)輕輕把(ba)聯(lian)軸(zhou)(zhou)器的一(yi)半(ban)從軸(zhou)(zhou)上(shang)慢(man)慢(man)拉下，注(zhu)意不要(yao)掉了，再(zai)用梅(mei)花扳手擰(ning)下泵(beng)軸(zhou)(zhou)吊緊(jin)螺栓(shuan)和(he)擋塊(kuai)，讓(rang)葉輪慢(man)慢(man)下沉至泵(beng)體，然后拆下另外一(yi)半(ban)聯(lian)軸(zhou)(zhou)器，拿(na)下泵(beng)軸(zhou)(zhou)擋圈(quan)。

　　拆卸西昌鎮機械密封：抓(zhua)住(zhu)密(mi)封彈簧順著泵軸往上提，就能拆下來了。

　　拆卸(xie)并(bing)(bing)清(qing)洗軸(zhou)(zhou)承(cheng)(cheng)座(zuo)：先輕輕松動一下(xia)軸(zhou)(zhou)承(cheng)(cheng)座(zuo)后用(yong)拆卸(xie)螺栓頂起軸(zhou)(zhou)承(cheng)(cheng)座(zuo)，并(bing)(bing)且沿著泵軸(zhou)(zhou)往上提而卸(xie)下(xia)，再用(yong)噴(pen)氣燃料(liao)清(qing)洗軸(zhou)(zhou)承(cheng)(cheng)及座(zuo)，裝(zhuang)前晾干并(bing)(bing)涂(tu)抹少許20號(hao)機械油用(yong)來(lai)潤(run)滑保護。

　　拆密封座(zuo)：擰(ning)下密封座(zuo)壓緊螺母，輕輕卸下密封座(zuo)并清(qing)洗。

　　西昌鎮機械密封裝配(pei)(pei)：在(zai)動(dong)(dong)、靜(jing)環鏡面上(shang)涂一層潔凈的20號潤(run)滑油，導軸承座也抹上(shang)潤(run)滑油，先把(ba)靜(jing)環輕(qing)輕(qing)定位裝入導軸承座，再在(zai)泵軸上(shang)抹上(shang)潤(run)滑油，把(ba)動(dong)(dong)環部(bu)分輕(qing)輕(qing)裝入泵軸上(shang)，用(yong)手輕(qing)推密(mi)封環應能伸縮自如，注意動(dong)(dong)、靜(jing)環部(bu)分的防轉部(bu)位需裝配(pei)(pei)到(dao)位。

　　裝(zhuang)(zhuang)聯(lian)(lian)軸器(qi)：在電機軸頭上裝(zhuang)(zhuang)上擋(dang)圈，裝(zhuang)(zhuang)上一(yi)(yi)半聯(lian)(lian)軸器(qi)，再在泵軸端和(he)聯(lian)(lian)軸器(qi)槽內裝(zhuang)(zhuang)上擋(dang)塊并(bing)用(yong)梅花扳手擰緊(jin)螺栓(shuan)；再裝(zhuang)(zhuang)上另(ling)一(yi)(yi)半聯(lian)(lian)軸器(qi)擰上內六角螺釘。安(an)裝(zhuang)(zhuang)聯(lian)(lian)軸器(qi)正確的(de)檢查(cha)要(yao)求：對分式聯(lian)(lian)軸器(qi)上下間(jian)隙需(xu)要(yao)均(jun)勻，用(yong)手盤動(dong)聯(lian)(lian)軸器(qi)幾圈檢查(cha)轉動(dong)的(de)靈活性。

　　裝(zhuang)密(mi)(mi)封(feng)座(zuo)：先將密(mi)(mi)封(feng)座(zuo)裝(zhuang)入橡膠(jiao)油(you)封(feng)，再(zai)把密(mi)(mi)封(feng)座(zuo)裝(zhuang)入泵蓋(gai)(gai)并壓(ya)在軸承座(zuo)上，擰緊(jin)螺母，確保所有安裝(zhuang)螺釘緊(jin)固(gu)(gu)。當安裝(zhuang)螺釘被用(yong)作(zuo)密(mi)(mi)封(feng)與(yu)軸之(zhi)間(jian)的驅動(dong)時(shi)，軸應(ying)打埋頭孔來加固(gu)(gu)連(lian)接，緊(jin)固(gu)(gu)壓(ya)蓋(gai)(gai)螺栓(shuan)時(shi)應(ying)該平穩緊(jin)固(gu)(gu)，并且不要使壓(ya)蓋(gai)(gai)受彈力(li)。在可(ke)能的地方使用(yong)4個以上螺釘的等間(jian)距(ju)壓(ya)蓋(gai)(gai)，緊(jin)固(gu)(gu)壓(ya)蓋(gai)(gai)螺栓(shuan)時(shi)，用(yong)塞尺(chi)檢查軸與(yu)壓(ya)蓋(gai)(gai)之(zhi)間(jian)的間(jian)隙，這在密(mi)(mi)封(feng)腔對壓(ya)蓋(gai)(gai)不導(dao)向時(shi)，顯(xian)得特別重要，因為壓(ya)蓋(gai)(gai)必(bi)須對中。
