應城機械密封利用機(ji)械方(fang)式傳(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，機(ji)械傳(chuan)(chuan)動(dong)(dong)(dong)(dong)在機(ji)械工程中應(ying)用非常廣泛，有(you)多種(zhong)(zhong)形(xing)式，主要包(bao)括皮帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、鏈傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、蝸桿蝸輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、齒(chi)(chi)輪齒(chi)(chi)條傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)螺旋傳(chuan)(chuan)動(dong)(dong)(dong)(dong)等。齒(chi)(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)能夠用于(yu)大(da)功(gong)率的(de)(de)場(chang)合(he)(he)，傳(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)準確(que)(que)，但(dan)一(yi)般要求較(jiao)(jiao)高的(de)(de)制造精度(du)和(he)安裝精度(du)。還有(you)一(yi)類是靠機(ji)件間(jian)的(de)(de)摩擦(ca)力傳(chuan)(chuan)遞(di)動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)(de)摩擦(ca)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，包(bao)括帶(dai)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)、繩傳(chuan)(chuan)動(dong)(dong)(dong)(dong)和(he)摩擦(ca)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)等。摩擦(ca)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)容易(yi)實(shi)現無(wu)級變速，可以適應(ying)軸間(jian)距較(jiao)(jiao)大(da)的(de)(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)場(chang)合(he)(he)，而過(guo)載打(da)滑還能起到(dao)緩沖和(he)保護傳(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置的(de)(de)作(zuo)用，但(dan)這種(zhong)(zhong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)一(yi)般不能用于(yu)大(da)功(gong)率的(de)(de)場(chang)合(he)(he)，也(ye)不能保證準確(que)(que)的(de)(de)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)比(bi)。

　　傳動形式多，但是應城機械密封的(de)更換工(gong)作(zuo)(zuo)大同小異，首先拆前需確認(ren)電機處于檢(jian)修狀態，擰下加油螺塞，用吸管把密封座腔內的(de)潤滑油吸出。準(zhun)備好放(fang)置泵零(ling)件(jian)的(de)工(gong)作(zuo)(zuo)臺及(ji)拆裝工(gong)具，切勿任意亂(luan)放(fang)亂(luan)用，避免(mian)碰壞泵的(de)零(ling)部件(jian)。

　　拆對分式聯(lian)軸(zhou)器：先把(ba)聯(lian)軸(zhou)器的固定內(nei)六角螺釘(ding)擰(ning)下(xia)來，再輕輕把(ba)聯(lian)軸(zhou)器的一半從(cong)軸(zhou)上慢慢拉下(xia)，注意不要掉了，再用梅(mei)花扳(ban)手擰(ning)下(xia)泵軸(zhou)吊緊螺栓和擋(dang)塊，讓(rang)葉輪(lun)慢慢下(xia)沉至泵體，然后拆下(xia)另外(wai)一半聯(lian)軸(zhou)器，拿下(xia)泵軸(zhou)擋(dang)圈。

　　拆卸應城機械密封：抓住密(mi)封(feng)彈簧順著(zhu)泵軸往上(shang)提，就(jiu)能拆下來了。

　　拆卸(xie)并清洗軸(zhou)承座(zuo)：先輕輕松動一下(xia)軸(zhou)承座(zuo)后用(yong)拆卸(xie)螺栓頂起軸(zhou)承座(zuo)，并且沿著泵軸(zhou)往上提而卸(xie)下(xia)，再用(yong)噴氣燃料清洗軸(zhou)承及座(zuo)，裝(zhuang)前晾干并涂抹少許(xu)20號機械油(you)用(yong)來潤滑保護。

　　拆密(mi)封(feng)座(zuo)：擰下(xia)密(mi)封(feng)座(zuo)壓緊螺母，輕輕卸下(xia)密(mi)封(feng)座(zuo)并清洗。

　　應城機械密封裝(zhuang)配：在動、靜環鏡(jing)面上涂一層潔凈(jing)的20號潤滑(hua)油(you)，導軸(zhou)(zhou)承座也抹(mo)上潤滑(hua)油(you)，先把靜環輕(qing)輕(qing)定位裝(zhuang)入導軸(zhou)(zhou)承座，再(zai)在泵軸(zhou)(zhou)上抹(mo)上潤滑(hua)油(you)，把動環部分輕(qing)輕(qing)裝(zhuang)入泵軸(zhou)(zhou)上，用手輕(qing)推密封環應(ying)能(neng)伸縮(suo)自(zi)如，注意動、靜環部分的防(fang)轉部位需裝(zhuang)配到(dao)位。

　　裝(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)(qi)：在(zai)電(dian)機(ji)軸(zhou)(zhou)頭上(shang)裝(zhuang)(zhuang)(zhuang)上(shang)擋圈(quan)，裝(zhuang)(zhuang)(zhuang)上(shang)一(yi)半聯(lian)軸(zhou)(zhou)器(qi)(qi)，再在(zai)泵軸(zhou)(zhou)端和聯(lian)軸(zhou)(zhou)器(qi)(qi)槽內裝(zhuang)(zhuang)(zhuang)上(shang)擋塊并用(yong)梅花(hua)扳手擰緊螺栓；再裝(zhuang)(zhuang)(zhuang)上(shang)另(ling)一(yi)半聯(lian)軸(zhou)(zhou)器(qi)(qi)擰上(shang)內六角螺釘。安裝(zhuang)(zhuang)(zhuang)聯(lian)軸(zhou)(zhou)器(qi)(qi)正確的檢查(cha)要求(qiu)：對分式(shi)聯(lian)軸(zhou)(zhou)器(qi)(qi)上(shang)下間隙需(xu)要均勻(yun)，用(yong)手盤動聯(lian)軸(zhou)(zhou)器(qi)(qi)幾圈(quan)檢查(cha)轉動的靈活性。

　　裝(zhuang)密封(feng)(feng)座(zuo)(zuo)：先將密封(feng)(feng)座(zuo)(zuo)裝(zhuang)入橡(xiang)膠油(you)封(feng)(feng)，再把密封(feng)(feng)座(zuo)(zuo)裝(zhuang)入泵蓋(gai)(gai)(gai)并(bing)壓(ya)(ya)在軸(zhou)(zhou)承(cheng)座(zuo)(zuo)上，擰(ning)緊(jin)(jin)螺(luo)母，確保所(suo)有(you)安裝(zhuang)螺(luo)釘(ding)緊(jin)(jin)固。當安裝(zhuang)螺(luo)釘(ding)被用作密封(feng)(feng)與軸(zhou)(zhou)之(zhi)間(jian)(jian)(jian)的(de)驅動時(shi)，軸(zhou)(zhou)應打埋頭孔來加(jia)固連(lian)接，緊(jin)(jin)固壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓時(shi)應該平穩緊(jin)(jin)固，并(bing)且不(bu)要(yao)使壓(ya)(ya)蓋(gai)(gai)(gai)受(shou)彈(dan)力。在可能的(de)地方使用4個以(yi)上螺(luo)釘(ding)的(de)等(deng)間(jian)(jian)(jian)距壓(ya)(ya)蓋(gai)(gai)(gai)，緊(jin)(jin)固壓(ya)(ya)蓋(gai)(gai)(gai)螺(luo)栓時(shi)，用塞尺檢查軸(zhou)(zhou)與壓(ya)(ya)蓋(gai)(gai)(gai)之(zhi)間(jian)(jian)(jian)的(de)間(jian)(jian)(jian)隙，這在密封(feng)(feng)腔對壓(ya)(ya)蓋(gai)(gai)(gai)不(bu)導向時(shi)，顯(xian)得(de)特別重要(yao)，因為壓(ya)(ya)蓋(gai)(gai)(gai)必須對中(zhong)。
