六合機械密封利用(yong)機(ji)械(xie)方式(shi)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)(li)和(he)運(yun)動(dong)(dong)(dong)(dong)的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)在(zai)機(ji)械(xie)工程中應用(yong)非常廣泛，有多種形式(shi)，主要包括(kuo)皮帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈(lian)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)輪(lun)齒(chi)條傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。齒(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用(yong)于大功率的場合，傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比準確(que)，但一般(ban)要求較(jiao)(jiao)高的制造精度和(he)安裝精度。還(huan)有一類(lei)是靠機(ji)件間的摩(mo)(mo)擦力(li)(li)傳(chuan)(chuan)(chuan)(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力(li)(li)和(he)運(yun)動(dong)(dong)(dong)(dong)的摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，包括(kuo)帶傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)摩(mo)(mo)擦輪(lun)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等(deng)。摩(mo)(mo)擦傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)容易(yi)實現無級變速(su)，可(ke)以(yi)適應軸(zhou)間距較(jiao)(jiao)大的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)場合，而過載(zai)打滑還(huan)能起(qi)到緩(huan)沖和(he)保護傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置的作用(yong)，但這種傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)一般(ban)不能用(yong)于大功率的場合，也(ye)不能保證準確(que)的傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)比。

　　傳動形式多，但是六合機械密封的更換工作大同小異，首先拆前需確認電機處(chu)于檢修狀態，擰下加油(you)螺塞，用(yong)吸(xi)管把(ba)密封座腔內(nei)的潤滑(hua)油(you)吸(xi)出。準(zhun)備(bei)好(hao)放置泵(beng)零(ling)件(jian)的工作臺及拆裝工具，切勿(wu)任意亂(luan)放亂(luan)用(yong)，避免碰壞(huai)泵(beng)的零(ling)部件(jian)。

　　拆對分式聯(lian)(lian)軸(zhou)器：先把聯(lian)(lian)軸(zhou)器的固定內六角螺釘擰下(xia)來(lai)，再輕(qing)輕(qing)把聯(lian)(lian)軸(zhou)器的一(yi)半從軸(zhou)上(shang)慢慢拉下(xia)，注意(yi)不要掉了，再用(yong)梅花扳(ban)手擰下(xia)泵軸(zhou)吊(diao)緊(jin)螺栓(shuan)和擋塊，讓葉輪慢慢下(xia)沉至泵體，然后拆下(xia)另外一(yi)半聯(lian)(lian)軸(zhou)器，拿下(xia)泵軸(zhou)擋圈。

　　拆卸六合機械密封：抓住密封彈(dan)簧順著泵(beng)軸往(wang)上提，就能拆下來了。

　　拆(chai)卸(xie)(xie)并清(qing)洗(xi)軸承座：先(xian)輕(qing)輕(qing)松動一下軸承座后用拆(chai)卸(xie)(xie)螺栓頂起軸承座，并且沿(yan)著泵(beng)軸往上提而卸(xie)(xie)下，再用噴(pen)氣燃(ran)料清(qing)洗(xi)軸承及座，裝前(qian)晾干并涂抹(mo)少許20號機(ji)械油(you)用來潤滑保護。

　　拆密封(feng)座：擰下密封(feng)座壓(ya)緊螺母(mu)，輕(qing)輕(qing)卸下密封(feng)座并清洗。

　　六合機械密封裝配：在動(dong)(dong)、靜(jing)(jing)環鏡面上涂一層潔凈(jing)的(de)(de)20號潤滑油，導(dao)軸承(cheng)座也抹(mo)(mo)上潤滑油，先(xian)把靜(jing)(jing)環輕(qing)輕(qing)定位裝入導(dao)軸承(cheng)座，再在泵軸上抹(mo)(mo)上潤滑油，把動(dong)(dong)環部(bu)分(fen)輕(qing)輕(qing)裝入泵軸上，用(yong)手輕(qing)推密(mi)封環應能伸(shen)縮自(zi)如，注意動(dong)(dong)、靜(jing)(jing)環部(bu)分(fen)的(de)(de)防轉部(bu)位需(xu)裝配到位。

　　裝(zhuang)(zhuang)聯軸器：在電機軸頭上(shang)(shang)(shang)裝(zhuang)(zhuang)上(shang)(shang)(shang)擋圈，裝(zhuang)(zhuang)上(shang)(shang)(shang)一(yi)半聯軸器，再在泵軸端和(he)聯軸器槽內裝(zhuang)(zhuang)上(shang)(shang)(shang)擋塊并(bing)用(yong)梅花扳手擰緊螺栓；再裝(zhuang)(zhuang)上(shang)(shang)(shang)另(ling)一(yi)半聯軸器擰上(shang)(shang)(shang)內六角(jiao)螺釘。安裝(zhuang)(zhuang)聯軸器正確的檢查(cha)要(yao)求：對分式聯軸器上(shang)(shang)(shang)下間隙需要(yao)均勻，用(yong)手盤(pan)動聯軸器幾圈檢查(cha)轉動的靈活性。

　　裝(zhuang)(zhuang)密(mi)(mi)封座(zuo)(zuo)(zuo)：先(xian)將密(mi)(mi)封座(zuo)(zuo)(zuo)裝(zhuang)(zhuang)入橡(xiang)膠(jiao)油(you)封，再(zai)把密(mi)(mi)封座(zuo)(zuo)(zuo)裝(zhuang)(zhuang)入泵蓋(gai)(gai)(gai)并壓(ya)(ya)在(zai)軸(zhou)承(cheng)座(zuo)(zuo)(zuo)上，擰緊螺母，確保所有安裝(zhuang)(zhuang)螺釘(ding)緊固(gu)。當安裝(zhuang)(zhuang)螺釘(ding)被用(yong)作密(mi)(mi)封與(yu)(yu)軸(zhou)之間的(de)驅(qu)動時(shi)，軸(zhou)應打埋頭孔(kong)來加固(gu)連接，緊固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺栓時(shi)應該平穩緊固(gu)，并且不(bu)要使壓(ya)(ya)蓋(gai)(gai)(gai)受(shou)彈力。在(zai)可能(neng)的(de)地(di)方使用(yong)4個以上螺釘(ding)的(de)等間距壓(ya)(ya)蓋(gai)(gai)(gai)，緊固(gu)壓(ya)(ya)蓋(gai)(gai)(gai)螺栓時(shi)，用(yong)塞(sai)尺檢查軸(zhou)與(yu)(yu)壓(ya)(ya)蓋(gai)(gai)(gai)之間的(de)間隙，這在(zai)密(mi)(mi)封腔對壓(ya)(ya)蓋(gai)(gai)(gai)不(bu)導向時(shi)，顯得(de)特(te)別重要，因為壓(ya)(ya)蓋(gai)(gai)(gai)必(bi)須對中(zhong)。
