昆山機械密封利用(yong)機(ji)械方式(shi)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)(li)和運動(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)械工程(cheng)中應用(yong)非常廣泛，有多(duo)種形式(shi)，主(zhu)要(yao)包括皮(pi)帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和螺(luo)旋傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠(gou)用(yong)于大(da)功(gong)率的(de)場合，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準(zhun)確，但(dan)一般(ban)要(yao)求較(jiao)高的(de)制造(zao)精(jing)度和安裝(zhuang)(zhuang)精(jing)度。還有一類是(shi)靠機(ji)件間的(de)摩(mo)(mo)擦力(li)(li)傳(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)(li)和運動(dong)(dong)(dong)(dong)的(de)摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括帶傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和摩(mo)(mo)擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易實現(xian)無級變速，可以適(shi)應軸間距較(jiao)大(da)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合，而過(guo)載打滑還能起到緩(huan)沖和保護(hu)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)(zhuang)置的(de)作(zuo)用(yong)，但(dan)這種傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般(ban)不能用(yong)于大(da)功(gong)率的(de)場合，也不能保證準(zhun)確的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是昆山機械密封的(de)更換工(gong)作大同小異，首先拆前需確(que)認電機(ji)處于檢修狀態，擰(ning)下加油(you)(you)螺(luo)塞(sai)，用吸管把密封(feng)座腔(qiang)內的(de)潤滑油(you)(you)吸出。準備(bei)好放置(zhi)泵(beng)零件的(de)工(gong)作臺及(ji)拆裝工(gong)具，切(qie)勿任(ren)意亂放亂用，避免碰壞泵(beng)的(de)零部件。

　　拆對分(fen)式聯軸(zhou)(zhou)器(qi)(qi)：先(xian)把(ba)聯軸(zhou)(zhou)器(qi)(qi)的固定內六角螺(luo)釘(ding)擰下(xia)來，再輕(qing)輕(qing)把(ba)聯軸(zhou)(zhou)器(qi)(qi)的一半從(cong)軸(zhou)(zhou)上慢慢拉下(xia)，注(zhu)意不要(yao)掉(diao)了(le)，再用梅(mei)花扳手擰下(xia)泵(beng)軸(zhou)(zhou)吊緊(jin)螺(luo)栓(shuan)和(he)擋塊，讓葉(xie)輪慢慢下(xia)沉(chen)至泵(beng)體，然后(hou)拆下(xia)另外一半聯軸(zhou)(zhou)器(qi)(qi)，拿下(xia)泵(beng)軸(zhou)(zhou)擋圈。

　　拆卸昆山機械密封：抓住密封(feng)彈簧順(shun)著(zhu)泵軸(zhou)往上提，就(jiu)能拆下(xia)來了。

　　拆卸并清(qing)洗軸(zhou)承(cheng)座(zuo)(zuo)：先輕輕松(song)動一下軸(zhou)承(cheng)座(zuo)(zuo)后用拆卸螺(luo)栓頂(ding)起軸(zhou)承(cheng)座(zuo)(zuo)，并且沿著泵軸(zhou)往上提而卸下，再用噴氣燃料(liao)清(qing)洗軸(zhou)承(cheng)及座(zuo)(zuo)，裝前晾干并涂抹少許20號(hao)機械油(you)用來潤滑(hua)保(bao)護。

　　拆密封(feng)座(zuo)：擰下密封(feng)座(zuo)壓緊螺母，輕(qing)輕(qing)卸下密封(feng)座(zuo)并清洗。

　　昆山機械密封裝(zhuang)配：在動(dong)、靜(jing)(jing)環(huan)(huan)鏡面上涂(tu)一層潔凈的20號潤滑(hua)油(you)，導軸(zhou)承座(zuo)(zuo)也抹(mo)上潤滑(hua)油(you)，先把(ba)靜(jing)(jing)環(huan)(huan)輕(qing)輕(qing)定位裝(zhuang)入導軸(zhou)承座(zuo)(zuo)，再在泵軸(zhou)上抹(mo)上潤滑(hua)油(you)，把(ba)動(dong)環(huan)(huan)部分輕(qing)輕(qing)裝(zhuang)入泵軸(zhou)上，用手(shou)輕(qing)推密封環(huan)(huan)應能伸縮自如，注意動(dong)、靜(jing)(jing)環(huan)(huan)部分的防(fang)轉部位需裝(zhuang)配到位。

　　裝(zhuang)(zhuang)(zhuang)(zhuang)聯軸(zhou)(zhou)(zhou)(zhou)器：在(zai)電(dian)機軸(zhou)(zhou)(zhou)(zhou)頭上(shang)(shang)裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)擋(dang)圈，裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)一半(ban)聯軸(zhou)(zhou)(zhou)(zhou)器，再在(zai)泵軸(zhou)(zhou)(zhou)(zhou)端和聯軸(zhou)(zhou)(zhou)(zhou)器槽內裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)擋(dang)塊并用梅花扳手擰(ning)緊螺(luo)栓(shuan)；再裝(zhuang)(zhuang)(zhuang)(zhuang)上(shang)(shang)另一半(ban)聯軸(zhou)(zhou)(zhou)(zhou)器擰(ning)上(shang)(shang)內六(liu)角(jiao)螺(luo)釘。安裝(zhuang)(zhuang)(zhuang)(zhuang)聯軸(zhou)(zhou)(zhou)(zhou)器正確(que)的檢(jian)查(cha)要求：對(dui)分式聯軸(zhou)(zhou)(zhou)(zhou)器上(shang)(shang)下間隙需要均(jun)勻(yun)，用手盤動(dong)聯軸(zhou)(zhou)(zhou)(zhou)器幾圈檢(jian)查(cha)轉動(dong)的靈活(huo)性。

　　裝密(mi)封(feng)座(zuo)：先將密(mi)封(feng)座(zuo)裝入橡膠油封(feng)，再(zai)把密(mi)封(feng)座(zuo)裝入泵蓋(gai)并壓(ya)(ya)在(zai)軸承座(zuo)上(shang)，擰緊(jin)(jin)螺(luo)母，確保所有安裝螺(luo)釘緊(jin)(jin)固(gu)。當安裝螺(luo)釘被用作密(mi)封(feng)與軸之間(jian)(jian)(jian)的(de)驅動時，軸應打埋(mai)頭(tou)孔來(lai)加固(gu)連接(jie)，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時應該平穩緊(jin)(jin)固(gu)，并且不(bu)要使壓(ya)(ya)蓋(gai)受彈(dan)力。在(zai)可能的(de)地方使用4個以上(shang)螺(luo)釘的(de)等間(jian)(jian)(jian)距壓(ya)(ya)蓋(gai)，緊(jin)(jin)固(gu)壓(ya)(ya)蓋(gai)螺(luo)栓時，用塞(sai)尺(chi)檢查軸與壓(ya)(ya)蓋(gai)之間(jian)(jian)(jian)的(de)間(jian)(jian)(jian)隙，這在(zai)密(mi)封(feng)腔對(dui)壓(ya)(ya)蓋(gai)不(bu)導向時，顯得(de)特別重要，因為(wei)壓(ya)(ya)蓋(gai)必須對(dui)中。
