安吉機械密封利(li)用機械方式傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)，機械傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)在(zai)機械工程(cheng)中應用非常廣泛，有多種形式，主要(yao)包括(kuo)皮帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)螺旋(xuan)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)能夠用于大功(gong)率(lv)的(de)場(chang)合，傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)準確，但一般要(yao)求較高的(de)制造精度和(he)安裝精度。還有一類是靠(kao)機件(jian)間(jian)的(de)摩(mo)(mo)擦(ca)力(li)傳(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)力(li)和(he)運(yun)動(dong)(dong)(dong)的(de)摩(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)，包括(kuo)帶傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)和(he)摩(mo)(mo)擦(ca)輪(lun)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)等。摩(mo)(mo)擦(ca)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)容易(yi)實現無(wu)級變速，可以適應軸間(jian)距較大的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)場(chang)合，而(er)過載打滑還能起到緩沖和(he)保護傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝置(zhi)的(de)作用，但這種傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)一般不能用于大功(gong)率(lv)的(de)場(chang)合，也不能保證準確的(de)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是安吉機械密封的更換工作大同小異，首先拆前(qian)需確認電機處于檢修(xiu)狀態，擰下加油螺塞，用吸管把密(mi)封座腔內的潤滑油吸出。準備好放置泵零件(jian)的工作臺及拆裝(zhuang)工具(ju)，切(qie)勿(wu)任意亂放亂用，避免(mian)碰壞泵的零部件(jian)。

　　拆對分(fen)式聯(lian)軸(zhou)(zhou)器(qi)：先(xian)把聯(lian)軸(zhou)(zhou)器(qi)的(de)固(gu)定內六角(jiao)螺釘擰(ning)下(xia)(xia)來，再(zai)輕輕把聯(lian)軸(zhou)(zhou)器(qi)的(de)一半(ban)從軸(zhou)(zhou)上慢慢拉下(xia)(xia)，注意不要掉(diao)了，再(zai)用(yong)梅花(hua)扳手擰(ning)下(xia)(xia)泵軸(zhou)(zhou)吊緊(jin)螺栓和(he)擋塊(kuai)，讓葉輪慢慢下(xia)(xia)沉至(zhi)泵體，然(ran)后拆下(xia)(xia)另外一半(ban)聯(lian)軸(zhou)(zhou)器(qi)，拿下(xia)(xia)泵軸(zhou)(zhou)擋圈。

　　拆卸安吉機械密封：抓(zhua)住密封彈(dan)簧順著泵軸往上(shang)提，就能(neng)拆(chai)下來了。

　　拆(chai)卸并(bing)清洗軸(zhou)承座(zuo)：先(xian)輕輕松(song)動一下軸(zhou)承座(zuo)后用(yong)拆(chai)卸螺栓頂起軸(zhou)承座(zuo)，并(bing)且沿(yan)著泵(beng)軸(zhou)往上提(ti)而卸下，再用(yong)噴氣(qi)燃(ran)料清洗軸(zhou)承及座(zuo)，裝前晾干并(bing)涂抹少許20號機(ji)械(xie)油用(yong)來(lai)潤滑(hua)保護。

　　拆密(mi)封(feng)(feng)座：擰(ning)下密(mi)封(feng)(feng)座壓緊(jin)螺母，輕輕卸下密(mi)封(feng)(feng)座并(bing)清(qing)洗。

　　安吉機械密封裝配：在動(dong)、靜(jing)(jing)環鏡面上(shang)(shang)涂一(yi)層潔(jie)凈的(de)20號(hao)潤(run)滑(hua)油(you)，導(dao)軸(zhou)承(cheng)座(zuo)也抹上(shang)(shang)潤(run)滑(hua)油(you)，先把靜(jing)(jing)環輕(qing)(qing)(qing)輕(qing)(qing)(qing)定位(wei)裝入導(dao)軸(zhou)承(cheng)座(zuo)，再在泵軸(zhou)上(shang)(shang)抹上(shang)(shang)潤(run)滑(hua)油(you)，把動(dong)環部(bu)分輕(qing)(qing)(qing)輕(qing)(qing)(qing)裝入泵軸(zhou)上(shang)(shang)，用手輕(qing)(qing)(qing)推密封(feng)環應能伸縮自如(ru)，注意動(dong)、靜(jing)(jing)環部(bu)分的(de)防(fang)轉(zhuan)部(bu)位(wei)需裝配到位(wei)。

　　裝聯軸(zhou)(zhou)器(qi)(qi)：在(zai)電(dian)機軸(zhou)(zhou)頭上(shang)(shang)(shang)(shang)裝上(shang)(shang)(shang)(shang)擋(dang)圈(quan)，裝上(shang)(shang)(shang)(shang)一半聯軸(zhou)(zhou)器(qi)(qi)，再在(zai)泵軸(zhou)(zhou)端和聯軸(zhou)(zhou)器(qi)(qi)槽內(nei)裝上(shang)(shang)(shang)(shang)擋(dang)塊(kuai)并用梅花扳(ban)手(shou)擰緊螺(luo)栓(shuan)；再裝上(shang)(shang)(shang)(shang)另一半聯軸(zhou)(zhou)器(qi)(qi)擰上(shang)(shang)(shang)(shang)內(nei)六角螺(luo)釘。安裝聯軸(zhou)(zhou)器(qi)(qi)正(zheng)確的檢查(cha)要(yao)求(qiu)：對分式聯軸(zhou)(zhou)器(qi)(qi)上(shang)(shang)(shang)(shang)下間隙需要(yao)均勻(yun)，用手(shou)盤動聯軸(zhou)(zhou)器(qi)(qi)幾圈(quan)檢查(cha)轉動的靈活性(xing)。

　　裝密(mi)封座(zuo)：先(xian)將密(mi)封座(zuo)裝入橡膠(jiao)油封，再(zai)把密(mi)封座(zuo)裝入泵蓋(gai)并壓(ya)(ya)(ya)在軸(zhou)承座(zuo)上，擰(ning)緊(jin)螺(luo)母，確(que)保所有安裝螺(luo)釘緊(jin)固(gu)(gu)(gu)。當安裝螺(luo)釘被用(yong)作(zuo)密(mi)封與(yu)軸(zhou)之間(jian)(jian)(jian)的驅動(dong)時，軸(zhou)應打埋(mai)頭孔來加固(gu)(gu)(gu)連(lian)接，緊(jin)固(gu)(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)栓時應該平(ping)穩緊(jin)固(gu)(gu)(gu)，并且不(bu)要使壓(ya)(ya)(ya)蓋(gai)受彈(dan)力(li)。在可能(neng)的地(di)方使用(yong)4個以(yi)上螺(luo)釘的等間(jian)(jian)(jian)距壓(ya)(ya)(ya)蓋(gai)，緊(jin)固(gu)(gu)(gu)壓(ya)(ya)(ya)蓋(gai)螺(luo)栓時，用(yong)塞尺檢查軸(zhou)與(yu)壓(ya)(ya)(ya)蓋(gai)之間(jian)(jian)(jian)的間(jian)(jian)(jian)隙，這(zhe)在密(mi)封腔對(dui)壓(ya)(ya)(ya)蓋(gai)不(bu)導向時，顯得特別(bie)重要，因為壓(ya)(ya)(ya)蓋(gai)必須對(dui)中。
